-* Introduction
-
-#+BEGIN_VERSE
-/The battle for liberty is never won, and is never lost. The battle for liberty always continues. It is never too late, and it is never soon enough, to defend freedom. No matter how enslaved we are, we always have hope. No matter how free we are we are never safe. Nothing ever limits the government, except the people. Any generation which fails to defend freedom will lose it, and the next generation will have to shed blood to gain it back./

-
-** What is FreedomBone?
-Today many of us rely upon "free" services in the cloud, such as Gmail, Facebook, Google+ and so on. It might appear that these services are indispensible infrastructure of the modern internet, but actually they're not strictly needed and the amount of value which they deliver to the average internet user is very marginal. It is possible to be a citizen of the internet and yet not use those things - to disintermediate the most well known companies and cut out their prurient or merely cringeworthy business models.
-
-FreedomBone is a personal home communications server based upon the BeagleBone Black hardware. It's small and cheap and will allow you to use email, have your own web site and do social networking in a federated way without needing to rely upon any intermediary companies other than your ISP.
-** Do I need any prior knowledge?
-In these instructions only a minimal level of familiarity with Linux is assumed. It's assumed that you know the basics of the /nano/ and /emacs/ editors, but it would be simple to also use other editors if you prefer.
-** Why should I do this?
-You should consider doing this if you are a freedom-oriented sort of person and you want to maintain sovereignty over your information. Laws in many places in the world consider you to have relinquished any property rights over data which you put onto a server not owned by youself (i.e. owned by a third party, such as Google or Facebook). The frequently cited and often absurd mantra is that there is "/no reasonable expectation of privacy/".
-
-If you don't like the idea of having all your communications intercepted and investigated by the Surveillance State then you should consider running a FreedomBone. If your profession involves maintaining confidentiality as an essential feature, such as legal or medical services, counselling, teaching or any sort of activism then you should consider running a FreedomBone. Especially if your activities include [[https://firstlook.org/theintercept/article/2014/03/20/inside-nsa-secret-efforts-hunt-hack-system-administrators/][systems administration]] or [[http://www.spiegel.de/international/germany/gchq-and-nsa-targeted-private-german-companies-a-961444.html][software engineering for any communications-related systems]] then it is highly likely that you have already been targeted and "tasked" by the surveillance apparatus.
-
-As Eben Moglen noted in his now famous [[https://www.youtube.com/watch?v=QOEMv0S8AcA]["Freedom in The Cloud"]] talk the simple fact of you keeping your own internet logs (found in the /var/log directory) puts a certain amount of power in your hands and takes it away from parties who would otherwise sell that information without your knowledge or permission to advertisers or other shady outfits who may not have your best interests at heart.
-** After it's installed will it need a lot of maintenance?
-So long as the hardware is ok the amount of maintenance needed should be very small. Unlike on Windows based systems you don't need to defragment drives or mess about with anti-virus programs. I ran a similar Sheevaplug system between 2010 and 2013 with only occasional software updates or reboots, and uptime was probably 99% or better.
-** Is it secure?
-Nothing is totally secure or infallible. You could have the most secure technology and yet still use easy to guess passwords. In general any software described as "uncrackable", "guaranteed secure" or "NSA-proof" is likely to be bogus and should be treated with suspicion. No matter what the hype may claim, all software has bugs so it's really a question of whether your communications are more secure or less secure. Using something like Freedombone will be likely to increase your degree of communications security to a level which is above average.
-
-This system will not defend you from an attacker who is actively trying to block or corrupt your communications, but I assume that doesn't apply in the majority of cases. Another thing to be aware of is that running a FreedomBone could make you more vulnerable to traffic analysis, since the server is associated with your home address and isn't a giant aggregation of users somewhere in the cloud. You need to weigh this alongside the additional legal protection which owning the server and having it in your own home gives you.
-
-FreedomBone should be far more secure than using popular cloud-based services which have spying built into them as a core feature (although not one which is typically advertised), but it is not necessarily any kind of impenetrable information fortress.
-
-This project is not only about security. It's also about having independence and at least in the realm of information being able to have more control over your own life, without having gatekeepers, censors or companies in the middle. That's the way that the internet was designed to be in the first place.
-** Will running a server all the time affect my electricity bill?
-Hardly at all. The BeagleBone Black consumes very little power - less than 5W. It would even be potentially possible to run it from a solar panel.
-** Can I use a Raspberry Pi or Cubieboard instead?
-These instructions are not highly specific to the Beaglebone Black and so will likely also work on other single board computers (SBCs) such as the [[https://en.wikipedia.org/wiki/Raspberry_pi][Raspberry Pi]] or [[https://en.wikipedia.org/wiki/Cubieboard][Cubieboard]]. The original Raspberry Pi only had 256MB of RAM and so the performance of some services may be more limited. The Beaglebone Black was chosen mainly because of its low cost, relatively good CPU performance for the price (by the standards of 2013) and also low electricity consumption. The Cubieboard is also another good alternative, with the A20 version having similar specifications but twice as much RAM as the BeagleBone Black.
-** Why should I trust the packages or source code downloaded from this site?
-If you're particularly security conscious then you shouldn't. Binary or source packages have only been included here for convenience and to avoid confusion. "/Go and find a Debian installation for the BeagleBone Black somewhere on the web/" is too vague an instruction for my liking, and I've attempted to keep things as concise and unambiguous as possible - particularly with an average or new Linux user in mind.
-
-However, for maximum security for those software systems which are not already packaged within the Debian repositories then seek out the original sources and verify the hashes independently.
-
-It's worth adopting an attitude of "/trust but verify/". Don't let fear of mass surveillance and [[https://www.techdirt.com/articles/20140207/08354426130/gchq-has-entire-program-dirty-tricks-including-honeypots-using-journalists-deleting-online-accounts.shtml]["dirty tricks"]] paralyse you into trusting nothing and consequently doing nothing. Doing nothing means that the surveillance apparatus has succeeded in keeping you under observation at all times.
-** Do I need to have a static IP address?
-This is often a question which people ask about running a server from home. The answer is that you don't need a static IP address. In the vast majority of cases you will have a dynamic IP address issued by your ISP, which may change from time to time. How then does the DNS system know how to resolve your domain name correctly? To do this you need to use a dynamic IP address system, such as [[http://freedns.afraid.org/][freeDNS]]. The details of that are explained [[Getting onto the web][here]]. Other services are available, but they're not usually /free as in beer/. In this guide a static IP address of 192.168.1.60 is only used within your /local network/ (i.e. not the big bad internet of public IP addresses), so that your internet router can be set up to send incoming traffic to the right computer.

--- Dalai Lama
-#+END_VERSE
-
-These instructions assume that you have the following ingredients.
-
-** A BeagleBone Black (BBB)
-
-It should come with a suitable USB cable for the initial setup. To make things look nicer you may also want to get a case for it.
-
-** An internet connection
-
-It is assumed that the most common situation is via a router installed at home. The router should have ethernet sockets on it and a web interface which allows you to forward ports (sometimes under the "firewall" settings), so that you can forward ssh and web traffic to the BBB.
-
-** microSD card
-
-To use as the main storage for the BBB. 16 or 32GB is fine, and can be obtained quite cheaply. Try to use Sandisk (class 10 or better) where possible and avoid cheaper cards which often have poor performance.
-
-You may also need an SD card adaptor or USB card reader in order to flash the operating image to the microSD card. For instance, many laptops have an SD card slot but not a microSD slot.
-
-** 5V/2A power supply
-
-With a plug suitable for powering the BBB. If you have some device with a USB socket nearby you may also be able to just use that for electrical power. However, powering from the USB cable alone might result in crashes when the system is under load, depending upon how many milliamps can be supplied by the USB hub/socket. If the system crashes due to running out of power then you will see that the LEDs on the BBB are continuously on, rather than flashing. One way to test whether the board has enough power is to try compiling a Linux kernel on it, but any CPU and disk intensive program will also suffice as a test.
-
-[[http://beagleboard.org/Support/FAQ][beagleboard.org]] gives the following advice on power supplies:
-
-#+BEGIN_VERSE
-/Power over USB is sufficient as long as the software and system running perform some management to keep it under the USB current limit threshold. For simplicity and maximum capability, powering over the 5V barrel connector is typically recommended./
-
-/The power adapter is required to provide 5V over a 5.5mm outer diameter and 2.1mm inner diameter barrel connector (a barrel connector length of 9.5mm is more than sufficient). The recommended supply current is at least 1.2A (or 6W), but at least 2A (or 10W) is recommended if you are going to connect up anything over the USB./
-#+END_VERSE
-
-The plug should be /centre positive/, meaning that the centre/tip is positive and the outer part is negative.
-
-** An ethernet patch cable
-
-Just an ordinary cat5 or cat6 cable that you can get from most electrical/computer stores.
-
-* Installing Debian onto the microSD card
-** Beaglebone Black
-
-The Debian Linux OS will be installed onto a small flash drive. It's a good idea to do this rather than using the internal flash, because it will allow you to easily create backups of the entire system if necessary using the dd command.
-
-Download the image.
-
-#+BEGIN_SRC: bash
-cd ~/
-wget http://freedombone.uk.to/debian-jessie-console-armhf-2014-08-13.tar.xz
-#+END_SRC
-
-Verify it.
-
-#+BEGIN_SRC: bash
-sha256sum debian-jessie-console-armhf-2014-08-13.tar.xz
-fc225cfb3c2dfad92cccafa97e92c3cd3db9d94f4771af8da364ef59609f43de
-#+END_SRC
-
-Uncompress it.
-
-#+BEGIN_SRC: bash
-tar xJf debian-jessie-console-armhf-2014-08-13.tar.xz
-cd debian-jessie-console-armhf-2014-08-13
-#+END_SRC
-
-Create the disk image, where sdX is the name of the flash drive (probably it will be sdb or sdc). An easy way to find out the device name of the flash drive is to enter the command:
-
-#+BEGIN_SRC: bash
-ls /dev/sd*
-#+END_SRC
-
-then plug in the flash drive and type the same command again. You'll be able to see the difference. Once you know the device name then you can proceed to install the image onto the flash drive.
-
-#+BEGIN_SRC: bash
-sudo apt-get install u-boot-tools dosfstools git-core kpartx wget parted
-sudo ./setup_sdcard.sh --mmc /dev/sdX --dtb beaglebone
-#+END_SRC
-
-Once that is completed we need to copy a boot file to enable the system to boot correctly. An example /uEnv.txt/ file can also be [[Boot (uEnv.txt)][seen here]].
-
-#+BEGIN_SRC: bash
-sudo cp /media/$USER/BOOT/bbb-uEnv.txt /media/$USER/BOOT/uEnv.txt
-sync
-#+END_SRC
-
-Now the microSD card can be safely removed via your file manager (usually right click and "safely remove" or "eject").
-
-** Cubieboard
-
-The Debian Linux OS will be installed onto a small flash drive. It's a good idea to do this rather than using the internal flash, because it will allow you to easily create backups of the entire system if necessary using the dd command.
-
-Download the Cubieboard image from http://cubian.org/downloads/
-
-#+BEGIN_SRC: bash
-sudo apt-get install p7zip-full
-7z x CUBIAN_IMAGE.7z
-#+END_SRC
-
-Create the disk image, where sdX is the name of the flash drive (probably it will be sdb or sdc). An easy way to find out the device name of the flash drive is to enter the command:
-
-#+BEGIN_SRC: bash
-ls /dev/sd*
-#+END_SRC
-
-then plug in the flash drive and type the same command again. You'll be able to see the difference. Once you know the device name then you can proceed to install the image onto the flash drive.
-
-#+BEGIN_SRC: bash
-sudo dd if=EXTRACTED_CUBIAN_IMAGE of=/dev/sdX bs=4096; sync

-** Things to be aware of
-*** A note on ssh
-When using ssh to log into the BBB if you get warnings of the type "/the ECDSA host key for domain differs from the key for the IP address/" then run the command:
-
-#+BEGIN_SRC: bash
-ssh-keygen -R
-#+END_SRC
-*** Passwords
-It's highly recommended that you use a password manager, such as KeepassX, and make all your passwords long random strings. It's also a good idea to use different passwords for different pieces of software, instead of one or two passwords for the whole system. That compartmentalises the security such that even if an attacker gains access to one system they can't necessarily get access to others.
-*** HTTPS
-Throughout these instructions self signed SSL certificates are used to implement access to web pages via HTTPS. The whole HTTPS security model upon which much of the internet currently rests seems broken in that it usually depends upon "trusted certificate authorities" who are not really trusted, except perhaps by the maintainers of certain web browser software. So all that HTTPS really guarantees is that you have an encrypted connection, but an encrypted connection /to who/ can be subject to doubt. As was seen in 2013 with the [[https://www.schneier.com/essay-455.html][information coming from Edward Snowden]], and also the [[http://en.wikipedia.org/wiki/Lavabit][Lavabit email service]], it's possible for companies/organisations to be compromised or bribed and SSL private keys for all users can be demanded using gagging orders or secret laws without any individual user ever being able to know that their communications is no longer secure..
-
-Not knowing who you're really connecting to is especially true for self-signed certificates, so it is in principle possible that when logging into a site with a username and password a system such as [[http://arstechnica.com/tech-policy/2013/11/uk-spies-continue-quantum-insert-attack-via-linkedin-slashdot-pages/][Quantum Insert]], or a compromised [[http://en.wikipedia.org/wiki/Domain_Name_System][DNS service]], could be used to direct the user to a fake copy of the login screen for the purposes of obtaining their login details. While this doesn't seem to be a major problem at the time of writing it's something to keep in mind. So if you can't log in or if you log in and what you see doesn't look like your site then it's possible that such a compromise could have taken place. Using a password manager with different login details for each site is one way to ensure that if one system is compromised then the attacker can't necessarily get access to all your other stuff.
-** Initial
-
-Eject the microSD card from your computer and plug it into the BBB, then connect the USB cable between the two. You may need to wait for a couple of minutes for the BBB to boot from the card, then you can then open a terminal and login via ssh.
-
-Note that if you're using a Cubieboard then the ssh login is different (see https://github.com/cubieplayer/Cubian/wiki/Get-started-with-Cubian) and it may be easier to directly edit the following files with the microSD card plugged into your laptop.
-
-#+BEGIN_SRC: bash
-ssh debian@192.168.7.2
-#+END_SRC
-
-The default password is /temppwd/
-
-Then log in as root:
-
-#+BEGIN_SRC: bash
-su
-#+END_SRC
-
-The default password is /root/
-
-The first thing to do is to change the passwords from their defaults.
-
-#+BEGIN_SRC: bash
-passwd
-#+END_SRC
-
-Then you will need to change the network interfaces. The main task here is to comment out the stuff related to usb0. That will enable you to plug the BBB into the back of a router and for it to be detectable on the network.
-
-#+BEGIN_SRC: bash
-nano /etc/network/interfaces
-#+END_SRC
-
-The resulting interfaces file should look like this:
-
-#+BEGIN_SRC: bash
-# This file describes the network interfaces available on your system
-# and how to activate them. For more information, see interfaces(5).
-
-# The loopback network interface
-auto lo
-iface lo inet loopback
-
-# The primary network interface
-allow-hotplug eth0
-iface eth0 inet static
- address 192.168.1.60
- netmask 255.255.255.0
- gateway 192.168.1.254
- dns-nameservers 213.73.91.35 85.214.20.141
-# Example to keep MAC address between reboots
-#hwaddress ether DA:AD:CE:EF:CA:FE
-
-# WiFi Example
-#auto wlan0
-#iface wlan0 inet dhcp
-# wpa-ssid "essid"
-# wpa-psk "password"
-
-# Ethernet/RNDIS gadget (g_ether)
-# ... or on host side, usbnet and random hwaddr
-# Note on some boards, usb0 is automaticly setup with an init script
-# in that case, to completely disable remove file [run_boot-scripts] from the boot partition
-#iface usb0 inet static
-# address 192.168.7.2
-# netmask 255.255.255.0
-# network 192.168.7.0
-# gateway 192.168.7.1
-#+END_SRC
-
-CTRL-o followed by ENTER to save, then CTRL-x to exit.
-
-In the above example "address 192.168.1.60" is a static IP address for the BBB, which will allow incoming network traffic to be directed from the router in a reliable manner. It should be outside of the DHCP range set up on the router.
-
-"gateway 192.168.1.254" should be the IP address of the router.
-
-Note that setting the DNS servers with dns-nameservers is important because some home routers do not allow you to change the DNS settings.
-
-Edit resolv.conf.
-
-#+BEGIN_SRC: bash
-nano /etc/resolv.conf
-#+END_SRC
-
-It should look something like the following:
-
-#+BEGIN_SRC: bash
-domain localdomain
-search localdomain
-nameserver 213.73.91.35
-nameserver 85.214.20.141
-#+END_SRC
-
-It's not a good idea to use the DNS servers provided by default by your ISP, since those are almost certainly subject to censorship and monitoring. Other possible IP addresses are:

-
-CTRL-o followed by ENTER to save, then CTRL-x to exit.
-
-Now disconnect the BBB from your computer and plug it into the router. You'll need an ethernet patch cable and you may also need a 5V/1A power supply for the BBB.
-
-If you go to the web administration screen for your internet router (often it's on 192.168.2.1 or 192.168.1.254) then after a few minutes you should see the BBB appear on the network. It's name will be "arm".
-
-If you're using a Cubieboard:
-
-#+BEGIN_SRC: bash
-nano /etc/apt/sources.list
-#+END_SRC
-
-Delete the existing sources and replace them with the sources [[Example software sources][listed here]], then save and exit. If you use the default Cubian software sources then dependency problems will occur later on.
-
-** Add a user
-
-Ssh back in to the BBB and login as root. In this example the BBB's IP address is 192.168.1.60.
-
-#+BEGIN_SRC: bash
-ssh-keygen -f "/home/myusername/.ssh/known_hosts" -R 192.168.1.60
-ssh debian@192.168.1.60
-su
-#+END_SRC
-
-Then make a new user. It's a bad idea to add users to the sudo group, because that then means that an attacker potentially only needs to know one password in order to get administrator access to the system. With no sudoers an attacker needs to know, or be able to obtain, two separate passwords to be able to really compromise the system.
-
-#+BEGIN_SRC: bash
-adduser myusername
-#+END_SRC
-
-Exit from the ssh login by typing "exit" a couple of times, then ssh back in as the new user. Make sure you use a difficult to guess password/phrase, or ideally a randomly generated password used together with a password manager such as KeepassX.
-
-Remove the default debian user.
-
-#+BEGIN_SRC: bash
-userdel -r debian
-#+END_SRC
-
-** Text editor
-
-For an editor which is less erratic than vi when used within a remote console such as Terminator.
-
-#+BEGIN_SRC: bash
-apt-get update
-apt-get install emacs24
-update-alternatives --set editor /usr/bin/emacs24
-#+END_SRC
-
-Some basic Emacs keys which will be useful to new users are:
-
-| Load a file | CTRL-x CTRL-f |
-| Save | CTRL-x CTRL-s |
-| Exit | CTRL-x CTRL-c |
-
-If you need an example Emacs configuration file to get you going then one can be [[Emacs setup][found here]].
-
-** Remove proprietary repositories
-
-By default the Debian operating system includes references to a repository which can be used to install some proprietary software. Because the source code of proprietary software cannot be independently audited or patched it could contain malicious backdoors or malware, or more likely because it's unmaintainable it could just be old and out of date and so may contain security vulnerabilities which the Surveillance State can make use of via its [[https://en.wikipedia.org/wiki/FOXACID][automated exploit delivery system]]. It's a good idea to remove those repositories as follows, so that the software from them can't be installed by accident:
-
-#+BEGIN_SRC: bash
-editor /etc/apt/sources.list
-#+END_SRC
-
-Then remove any references to *non-free*, save and exit. With that done you can be sure that all the software on your system is [[https://en.wikipedia.org/wiki/Free_and_open_source_software][FOSS]], and so can be checked, updated or customized as necessary.
-** Enable backports
-
-To enable some newer packages add backports to the repositories.
-
-#+BEGIN_SRC: bash
-echo "deb http://ftp.us.debian.org/debian jessie-backports main" >> /etc/apt/sources.list
-apt-get update
-apt-get dist-upgrade
-apt-get install ca-certificates
-#+END_SRC
-
-** Configure your location/language
-
-Not everybody lives in the US or Europe. You may want to change your location and language settings accordingly.
-
-#+BEGIN_SRC: bash
-dpkg-reconfigure locales
-apt-get install keyboard-configuration
-reboot
-#+END_SRC
-
-After reboot is complete ssh back in as the root user, then to verify the change.
-
-#+BEGIN_SRC: bash
-locale -a
-#+END_SRC
-
-Set your time zone with:
-
-#+BEGIN_SRC: bash
-tzselect
-#+END_SRC
-
-For example, for British time:
-

-** Upgrade the kernel
-Using a more recent kernel should improve stability of the system and also allow it to make use of hardware random number generation, which improves the overall security. Please note that this kernel is specific to the BBB, so if you're using a Raspberry Pi, Cubieboard or other SBC then look elsewhere on the web for information about upgrading the kernel. Newer kernels are also available at http://rcn-ee.net/deb/jessie-armhf ("bone" in the name indicates kernels with BBB specific patches).
-
-#+BEGIN_SRC: bash
-cd /opt/scripts/tools
-./update_kernel.sh --kernel v3.15.10-bone7
-reboot
-#+END_SRC
-
-After the system has rebooted you can ssh back unto it and log in as the root user. You can check that the kernel version has changed with the command:
-
-#+BEGIN_SRC: bash
-uname -mrs
-#+END_SRC
-
-Note: If you're upgrading to any other kernel version and the BBB fails to reboot, with lights continuously on, then remove power, take out the microSD, insert it into your laptop then do something like "*sudo emacs /media/$USER/rootfs/boot/uEnv.txt*" and change the kernel version to the previous one which you were using, then eject the microSD drive, re-insert it into the BBB and re-apply power.

-** Random number generation
-
-#+BEGIN_VERSE
-/Near as I can tell, the answer on what has been requested is everything: deliberate weakenings of encryption algorithms, deliberate weakenings of random number generations, copies of master keys, encryption of the session key with an NSA-specific key … everything./
-
--- Bruce Schneier, on the 2013 leaked NSA documents
-#+END_VERSE
-
-The security of encryption depends upon the randomness of the random source used on your system. If it isn't very random then it may be far more vulnerable to cryptanalysis, and it's known that in the past some dubious agencies have encouraged the use of flawed random number generators to assist with their prurient activities. Randomness - typically referred to as /entropy/ - is often gathered from factors such as the timing of key presses or mouse movements, but since the BBB won't have such devices plugged into it this reduces the amount of entropy available.
-
-*** On the Beaglebone Black
-Computers can't really generate truly random numbers by themselves, since they're deterministic and so operate in a highly predictable manner. Fortunately, the BBB has an onboard hardware random number generator, which is a physical process which behaves randomly and which can then be read into the computer and stored for later use in encryption algorithms.
-
-Information on exactly how the hardware random number generator on the Beaglebone AM335x CPU works [[http://e2e.ti.com/support/arm/sitara_arm/f/791/t/292794.aspx][seems hard to come by]], but we can later use some software to verify that it does indeed produce random numbers and hasn't been deliberately weakened.
-
-If you are using a Beaglebone and have updated the kernel then install:
-
-#+BEGIN_SRC: bash
-apt-get install rng-tools
-editor /etc/default/rng-tools
-#+END_SRC
-
-Uncomment *HRNGDEVICE=/dev/hwrng*, save and exit then restart the daemon.
-
-#+BEGIN_SRC: bash
-service rng-tools restart
-#+END_SRC
-
-Your BBB will now use hardware to generate random numbers.
-
-*** On other Single Board Computers
-If you are not using a Beaglebone (a Cubieboard for example), or if you didn't update the kernel, then you can still improve the random number generation by installing:
-
-#+BEGIN_SRC: bash
-apt-get install haveged
-#+END_SRC
-
-*** Verifying random number quality
-
-#+BEGIN_VERSE
-/Living in a surveillance state is exactly like being guilty until proven guilty./
-
--- Mohammad Tarakiyee
-#+END_VERSE
-
-You can check how much randomness (entropy) is available with:
-
-#+BEGIN_SRC: bash
-cat /proc/sys/kernel/random/entropy_avail
-#+END_SRC
-
-Ideally it should be in the range 1000-4096. If it is persistently below 500 then there may be a problem with your system which could make it less secure.
-
-To verify that random number generation is good on the BBB run:
-
-#+BEGIN_SRC: bash
-cat /dev/hwrng | rngtest -c 1000
-#+END_SRC
-
-You should see something like this, with zero or a small number of failures:

-
-Install the hashlet [[./images/hashlet_installed.jpg][like this]] on the BBB, then install some dependencies.

-#+BEGIN_SRC: bash
-cd hashlet
-chmod o+rw /dev/i2c*

-#+END_SRC
-
-To check the initial state of the device:
-
-#+BEGIN_SRC: bash
-hashlet --bus=/dev/i2c-2 state
-#+END_SRC
-
-It should return the message "/Factory/". This is intended to provide an indication that the hardware hasn't been tampered with by [[https://en.wikipedia.org/wiki/Tailored_Access_Operations][TAO]] or other shady outfits in transit. If /i2c-2/ fails then try /i2c-1/ or /i2c-0/.
-
-#+BEGIN_SRC: bash
-hashlet --bus=/dev/i2c-2 personalize
-#+END_SRC
-
-Nothing should be returned by this command, but a file called ~/.hashlet will be generated which is the private key of the device. This personalization process is a one-time operation which physically alters the hardware, so it would not be trivial to reset the device back to "Factory" again. To make sure it's only accessible by the root user:
-
-#+BEGIN_SRC: bash
-chmod 400 ~/.hashlet
-#+END_SRC

-The rate of entropy generation by the Hashlet seems very slow compared to */dev/hwrng*, and this is most likely because of the I2C interface. So it's probably a good idea to keep hwrng as the main random source and only use the Hashlet's random number generator for any ancillary stuff.

-** Getting onto the web
-Create a subdomain on [[http://freedns.afraid.org][freeDNS]]. You may need to click on "/subdomains/" a couple of times. FreeDNS is preferred because it is one of the few domain name providers which supports genuinely free (as in beer) accounts. So if your budget is tiny or non-existent you can still participate as a first class citizen of the internet. If you do have money to spend there is also a premium option.
-
-Select "/dynamic DNS/" then click "/quick cron example/"
-
-An example would look like:
-
-#+BEGIN_SRC: bash

-#+END_SRC
-
-It's important to make sure that you change the *http* to *https*, since this will help to prevent a potential attacker from hijacking your site and redirecting it to a fake version for the purposes of obtaining your login details.
-
-Edit */etc/crontab* and append that to the top of the file, underneath the heading line which looks like this:
-
-#+BEGIN_SRC: bash
-# m h dom mon dow user command
-#+END_SRC
-
-In general the most frequently run crontab entries should be at the top. Then save and exit.
-
-Via your router's firewall settings you should now open port 22 (secure shell). This will allow you to ssh into your BBB from any location - not just your own local network.
-
-The freeDNS subdomain which you just created will hereafter just be refered to as "/your domain name/".
-
-If you have multiple freedns subdomains then you may want to rationalise that a little within */etc/crontab*. Rather than listing them all individually create a script:
-
-#+BEGIN_SRC: bash
-editor /usr/bin/dynamicdns
-#+END_SRC
-
-Add however many freedns subdomains you have.
-
-#+BEGIN_SRC: bash
-#!/bin/bash
-# subdomain name 1
-wget -O - https://freedns.afraid.org/dynamic/update.php?== >> /dev/null 2>&1
-# subdomain name 2
-wget -O - https://freedns.afraid.org/dynamic/update.php?== >> /dev/null 2>&1
-...
-#+END_SRC
-
-Save and exit, then make the script runnable and only readable by the root user.
-
-#+BEGIN_SRC: bash
-chmod 600 /usr/bin/dynamicdns

-#+END_SRC
-
-Then within */etc/crontab*
-
-#+BEGIN_SRC: bash
-editor /etc/crontab
-#+END_SRC
-
-You can replace the multiple freedns entries with a single line:
-
-#+BEGIN_SRC: bash

-#+END_SRC
-
-Then save and exit and restart the cron daemon.

-It's convenient to have the clock on your server automatically synchronised with other servers on the internet so that you don't need to set the clock manually. The usual way of doing this is via [[https://en.wikipedia.org/wiki/Network_Time_Protocol][NTP]], but that method uses unencrypted signals which could potentially be interfered with in order to mess up your system. /tlsdate/ provides a slightly more secure way of setting the date and time over a SSL/TLS connection to a known good time source.

-/The NSA also attacks network devices directly: routers, switches, firewalls, etc. Most of these devices have surveillance capabilities already built in; the trick is to surreptitiously turn them on. This is an especially fruitful avenue of attack; routers are updated less frequently, tend not to have security software installed on them, and are generally ignored as a vulnerability./
-
--- Bruce Schneier
-#+END_VERSE
-
-A basic firewall limits the maximum rate at which connections can be made and closes any unused ports, and this helps to defend against various kinds of DDOS attack. Your internet router may contain a firewall, but chances are that it also contains proprietary software which can be remotely changed/updated by the ISP. Unless you're running free software, such as [[https://en.wikipedia.org/wiki/OpenWrt][OpenWrt]], on your internet router then it's reasonable to assume that the device is hostile and could be conducting surveillance, trying to do [[https://en.wikipedia.org/wiki/Man-in-the-middle_attack]["man in the middle"]] attacks or be pushing "implants" onto the computers and mobile devices on your local network. That means that your server needs its own firewall.

-Email is not very secure, but its usefulness and ubiquity mean that it's likely to continue as a primary communications method for many years to come. You can encrypt the contents of email using PGP/GPG, but very few people do that and even for those that do the metadata (the From/To/CC/BCC) is always transmitted in the clear as a fundamental aspect of the protocol, allowing an attacker to easily construct detailed models of people's social network and life patterns even without knowing the content.

-#
-# Unless you specify which option file to use (with the command line
-# option "--options filename"), GnuPG uses the file ~/.gnupg/gpg.conf
-# by default.
-#
-# An options file can contain any long options which are available in
-# GnuPG. If the first non white space character of a line is a '#',
-# this line is ignored. Empty lines are also ignored.
-#
-# See the man page for a list of options.
-
-# Uncomment the following option to get rid of the copyright notice
-
-#no-greeting
-
-# If you have more than 1 secret key in your keyring, you may want to
-# uncomment the following option and set your preferred keyid.
-
-#default-key 621CC013
-
-# If you do not pass a recipient to gpg, it will ask for one. Using
-# this option you can encrypt to a default key. Key validation will
-# not be done in this case. The second form uses the default key as
-# default recipient.
-
-#default-recipient some-user-id
-#default-recipient-self
-
-# Use --encrypt-to to add the specified key as a recipient to all
-# messages. This is useful, for example, when sending mail through a
-# mail client that does not automatically encrypt mail to your key.
-# In the example, this option allows you to read your local copy of
-# encrypted mail that you've sent to others.
-
-#encrypt-to some-key-id
-
-# By default GnuPG creates version 4 signatures for data files as
-# specified by OpenPGP. Some earlier (PGP 6, PGP 7) versions of PGP
-# require the older version 3 signatures. Setting this option forces
-# GnuPG to create version 3 signatures.
-
-#force-v3-sigs
-
-# Because some mailers change lines starting with "From " to ">From "
-# it is good to handle such lines in a special way when creating
-# cleartext signatures; all other PGP versions do it this way too.
-
-#no-escape-from-lines
-
-# If you do not use the Latin-1 (ISO-8859-1) charset, you should tell
-# GnuPG which is the native character set. Please check the man page
-# for supported character sets. This character set is only used for
-# metadata and not for the actual message which does not undergo any
-# translation. Note that future version of GnuPG will change to UTF-8
-# as default character set. In most cases this option is not required
-# as GnuPG is able to figure out the correct charset at runtime.
-
-#charset utf-8
-
-# Group names may be defined like this:
-# group mynames = paige 0x12345678 joe patti
-#
-# Any time "mynames" is a recipient (-r or --recipient), it will be
-# expanded to the names "paige", "joe", and "patti", and the key ID
-# "0x12345678". Note there is only one level of expansion - you
-# cannot make an group that points to another group. Note also that
-# if there are spaces in the recipient name, this will appear as two
-# recipients. In these cases it is better to use the key ID.
-
-#group mynames = paige 0x12345678 joe patti
-
-# Lock the file only once for the lifetime of a process. If you do
-# not define this, the lock will be obtained and released every time
-# it is needed, which is usually preferable.
-
-#lock-once
-
-# GnuPG can send and receive keys to and from a keyserver. These
-# servers can be HKP, email, or LDAP (if GnuPG is built with LDAP
-# support).
-#
-# Example HKP keyserver:
-# hkp://keys.gnupg.net
-# hkp://subkeys.pgp.net
-#
-# Example email keyserver:
-# mailto:pgp-public-keys@keys.pgp.net
-#
-# Example LDAP keyservers:
-# ldap://keyserver.pgp.com
-#
-# Regular URL syntax applies, and you can set an alternate port
-# through the usual method:
-# hkp://keyserver.example.net:22742
-#
-# Most users just set the name and type of their preferred keyserver.
-# Note that most servers (with the notable exception of
-# ldap://keyserver.pgp.com) synchronize changes with each other. Note
-# also that a single server name may actually point to multiple
-# servers via DNS round-robin. hkp://keys.gnupg.net is an example of
-# such a "server", which spreads the load over a number of physical
-# servers. To see the IP address of the server actually used, you may use
-# the "--keyserver-options debug".
-
-keyserver hkp://keys.gnupg.net
-#keyserver mailto:pgp-public-keys@keys.nl.pgp.net
-#keyserver ldap://keyserver.pgp.com
-
-# Common options for keyserver functions:
-#
-# include-disabled : when searching, include keys marked as "disabled"
-# on the keyserver (not all keyservers support this).
-#
-# no-include-revoked : when searching, do not include keys marked as
-# "revoked" on the keyserver.
-#
-# verbose : show more information as the keys are fetched.
-# Can be used more than once to increase the amount
-# of information shown.
-#
-# use-temp-files : use temporary files instead of a pipe to talk to the
-# keyserver. Some platforms (Win32 for one) always
-# have this on.
-#
-# keep-temp-files : do not delete temporary files after using them
-# (really only useful for debugging)
-#
-# http-proxy="proxy" : set the proxy to use for HTTP and HKP keyservers.
-# This overrides the "http_proxy" environment variable,
-# if any.
-#
-# auto-key-retrieve : automatically fetch keys as needed from the keyserver
-# when verifying signatures or when importing keys that
-# have been revoked by a revocation key that is not
-# present on the keyring.
-#
-# no-include-attributes : do not include attribute IDs (aka "photo IDs")
-# when sending keys to the keyserver.
-
-keyserver-options auto-key-retrieve
-
-# Display photo user IDs in key listings
-
-# list-options show-photos
-
-# Display photo user IDs when a signature from a key with a photo is
-# verified
-
-# verify-options show-photos
-
-# Use this program to display photo user IDs
-#
-# %i is expanded to a temporary file that contains the photo.
-# %I is the same as %i, but the file isn't deleted afterwards by GnuPG.
-# %k is expanded to the key ID of the key.
-# %K is expanded to the long OpenPGP key ID of the key.
-# %t is expanded to the extension of the image (e.g. "jpg").
-# %T is expanded to the MIME type of the image (e.g. "image/jpeg").
-# %f is expanded to the fingerprint of the key.
-# %% is %, of course.
-#
-# If %i or %I are not present, then the photo is supplied to the
-# viewer on standard input. If your platform supports it, standard
-# input is the best way to do this as it avoids the time and effort in
-# generating and then cleaning up a secure temp file.
-#
-# If no photo-viewer is provided, GnuPG will look for xloadimage, eog,
-# or display (ImageMagick). On Mac OS X and Windows, the default is
-# to use your regular JPEG image viewer.
-#
-# Some other viewers:
-# photo-viewer "qiv %i"
-# photo-viewer "ee %i"
-#
-# This one saves a copy of the photo ID in your home directory:
-# photo-viewer "cat > ~/photoid-for-key-%k.%t"
-#
-# Use your MIME handler to view photos:
-# photo-viewer "metamail -q -d -b -c %T -s 'KeyID 0x%k' -f GnuPG"
-
-# Passphrase agent
-#
-# We support the old experimental passphrase agent protocol as well as
-# the new Assuan based one (currently available in the "newpg" package
-# at ftp.gnupg.org/gcrypt/alpha/aegypten/). To make use of the agent,
-# you have to run an agent as daemon and use the option
-#
-# use-agent
-#
-# which tries to use the agent but will fallback to the regular mode
-# if there is a problem connecting to the agent. The normal way to
-# locate the agent is by looking at the environment variable
-# GPG_AGENT_INFO which should have been set during gpg-agent startup.
-# In certain situations the use of this variable is not possible, thus
-# the option
-#
-# --gpg-agent-info=::1
-#
-# may be used to override it.
-
-# Automatic key location
-#
-# GnuPG can automatically locate and retrieve keys as needed using the
-# auto-key-locate option. This happens when encrypting to an email
-# address (in the "user@example.com" form), and there are no
-# user@example.com keys on the local keyring. This option takes the
-# following arguments, in the order they are to be tried:
-#
-# cert = locate a key using DNS CERT, as specified in RFC-4398.
-# GnuPG can handle both the PGP (key) and IPGP (URL + fingerprint)
-# CERT methods.
-#
-# pka = locate a key using DNS PKA.
-#
-# ldap = locate a key using the PGP Universal method of checking
-# "ldap://keys.(thedomain)". For example, encrypting to
-# user@example.com will check ldap://keys.example.com.
-#
-# keyserver = locate a key using whatever keyserver is defined using
-# the keyserver option.
-#
-# You may also list arbitrary keyservers here by URL.
-#
-# Try CERT, then PKA, then LDAP, then hkp://subkeys.net:
-#auto-key-locate cert pka ldap hkp://subkeys.pgp.net

-#+BEGIN_SRC: bash
-gpg --gen-key
-#+END_SRC
-
-You can find your GPG key ID by entering:
-
-#+BEGIN_SRC: bash
-gpg --list-keys
-#+END_SRC
-
-The key ID is the second part of the string of numbers and letters. So for example in:
-
-#+BEGIN_SRC: bash
-pub 4096R/EA982E38 2012-05-20
-#+END_SRC
-
-the key ID is EA982E38. Now send your public key to a server so that others can find it.
-
-#+BEGIN_SRC: bash
-gpg --send-keys $MYGPGKEYID
-#+END_SRC
-*** root settings
-If you later create an encrypted mailing list then the root user will also need to have good GPG settings so that it can generate key pairs for the list. The easiest way to ensure this is to do the following, replacing /myusername/ with your username:
-
-#+BEGIN_SRC: bash
-su
-cp -r /home/myusername/.gnupg ~/
-chown -R root:root ~/.gnupg
-#+END_SRC
-
-** Protect processes
-Because the BBB has limited RAM some processes may occasionally be automatically killed if physical memory availability is getting too low. The way in which processes are chosen to be sacrificed is not particularly intelligent, and so can result in vital systems being stopped. To try to prevent that from ever happening the following script can be used, which should ensure that at a minimum ssh, email and mysql keep running.
-
-#+BEGIN_SRC: bash
-editor /usr/bin/protectprocesses
-#+END_SRC
-
-Add the following:
-
-#+BEGIN_SRC: bash
-#!/bin/bash
-
-declare -a protect=('/usr/sbin/sshd' '/usr/sbin/mysqld --basedir=/usr' '/bin/sh /usr/bin/mysqld_safe' '/usr/sbin/exim4')
-
-for p in "${protect[@]}"
-do
- OOM_PROC_ID=$(ps aux | grep '$p' | grep -v grep | head -n 1 | awk -F ' ' '{print $2}')
- if [ ! -z "$OOM_PROC_ID" ]; then
- echo -1000 >/proc/$OOM_PROC_ID/oom_score_adj
- echo -17 >/proc/$OOM_PROC_ID/oom_adj
- fi
-done
-#+END_SRC
-
-Save and exit, then edit the cron jobs:
-
-#+BEGIN_SRC: bash
-editor /etc/crontab
-#+END_SRC
-
-And add the line:
-
-#+BEGIN_SRC: bash
-*/1 * * * * root /usr/bin/timeout 30 /usr/bin/protectprocesses
-#+END_SRC
-
-Then save and exit and restart cron.
-
-#+BEGIN_SRC: bash
-chmod +x /usr/bin/protectprocesses
-service cron restart
-#+END_SRC
-
-Here cron is used so that if we stop one of the relevant processes and then restart it then its oom priority will be reassigned again

-
-Finally you can then type *mutt* to get access to your email. Hence as a fallback, or if you prefer as the primary way of accessing email, you can ssh into the BBB and use the mutt command line email client. Ssh clients are available for all operating systems, and also you should be reasonably protected from passive surveillance between wherever you are and the BBB (although not between the BBB and the wider internet), which can be useful if you are for example using an Android tablet from a cafe or railway station.
-
-To use the address book system open an email and then to add the sender to the address list press the A key. It will ask you for an alias which may be used the next time you want to send a mail. Alternatively you may just edit the *~/.mutt-alias* file directly to add email addresses.
-
-Some useful keys to know are:
-
-| ESC / | Search for text within message contents |
-| "/" | Search for text within headers |
-| * | Move to the last message |
-| TAB | Move to the next unread message |
-| d | Delete a message |
-| u | Undelete a mail which is pending deletion |
-| $ | Delete all messages selected and check for new messages |
-| a | Add to the address book |
-| m | Send a new mail |
-| ESC-m | Mark all messages as having been read |
-| S | Mark a message as spam |
-| H | Mark a message as ham |
-| CTRL-b | Toggle side bar on/off |
-| CTRL-n | Next mailbox (on side bar) |
-| CTRL-p | Previous mailbox (on side bar) |
-| CTRL-o | Open mailbox (on side bar) |
-| ] | Expand or collapse all threads |
-| [ | Expand of collapse the current thread |
-| CTRL-k | Import a PGP/GPG public key |
-
-One of the most common things which you might wish to do is to send an email. To do this first press /m/ to create a new message. Enter the address to send to and the subject, then after a few seconds the Emacs editor will appear with a blank document. Type your email then press /CTRL-x CTRL-s/ to save it and /CTRL-x CTRL-c/ to exit. You will then see a summary of the email to be sent out. Press /y/ to send it and then enter your GPG key passphrase (the one you gave when creating a PGP/GPG key). The purpose of that is to add a signature which is a strong proof that the email was written by you and not by someone else.

-For maximum speed and efficiency the recommended email client is Mutt, accessed via ssh, but non-technical people who aren't using an Android app are unlikely to want to use email in that manner. So it's a good idea to also have a webmail system installed, both for accessibility and as a fallback should ssh not be available due to port blocking.

-#+END_VERSE
-
-Another common way in which you may want to access email is via Thunderbird. This may be especially useful if you're trying to convert former Windows users who may previously have been using some version of Outlook.
-
-The following instructions should be carried out on the client machines (laptop, etc), not on the BBB itself.
-
-**** Initial setup
-
-Install *Thunderbird* and *Enigmail*. How you do this just depends upon your distro and software manager or "app store".
-
-Open Thinderbird
-
-Select "*Skip this and use existing email*"
-
-Enter your name, email address (myusername@mydomainname.com) and the password for your user (the one from [[Add a user]]).
-
-You'll get a message saying "/Thunderbird failed to find the settings/"
-
-The settings should be as follows, substituting /mydomainname.com/ for your domain name and /myusername/ for the username given previously in [[Add a user]].
-
- * Incoming: IMAP, mydomainname.com, 993, SSL/TLS, Normal Password
- * Outgoing: SMTP, mydomainname.com, 465, SSL/TLS, Normal Password
- * Username: myusername
-
-Click *Done*.
-
-Click *Get Certificate* and make sure "*permanently store this exception*" is selected", then click *Store Security Exception*.
-
-From OpenPGP setup select "*Yes, I would like the wizard to get me started*". If the wizard doesn't start automatically then "setup wizard" can be selected from OpenPGP on the menu bar.
-
-Select "*Yes, I want to sign all of my email*"
-
-Select "*No, I will create per-recipient rules*"
-
-Select "*yes*" to change default settings.
-
-**** If you have existing GPG key
-
-Export your GPG public and private keys.
-
-#+BEGIN_SRC: bash
-gpg --output ~/public_key.txt --armor --export KEY_ID
-gpg --output ~/private_key.txt --armor --export-secret-key KEY_ID
-#+END_SRC
-
-Select "*I have existing public and private keys*".
-
-Select your public and private GPG exported key files.
-
-Select the account which you want to use and click *Next*, *Next* and *Finish*.
-
-Remove your exported key files.
-
-#+BEGIN_SRC: bash
-shred -zu ~/public_key.txt
-shred -zu ~/private_key.txt
-#+END_SRC
-
-**** If you don't have any existing GPG or PGP key
-Select "*I want to create a new key pair*"
-
-Enter a passphrase and click *Next* a couple of times.
-
-Click *Generate Certificate* to generate a revocation certificate.
-
-Enter the passphrase which you gave previously.
-
-Click *Finish*
-
-From the menu select *OpenPGP* and then *Key Management*. Make sure that *Display all keys* is selected and then select your key. Select *Keyserver* on the menu and then *Upload Public Keys*. This will upload your public key to a key server so that others can find it.
-
-Select *File* from the menu then *Export keys to file*. Click on *Export Secret keys* and select a location to save them to. It's a good idea to save them to a USB stick which can then be removed from the computer and carried around on a keyring together with your physical keys. If you need to set up GPG or Thunderbird/Enigmail on others then this file will be used to import your keys.
-
-**** Using for the first time
-
-Click on the Thunderbird menu, which looks like three horizontal bars on the right hand side.
-
-Hover over *preferences* and then *Account settings*.
-
-Select *OpenPGP Security* and make sure that *use PGP/MIME by default* is ticked. This will enable you to sign/encrypt attachments, HTML bodies and UTF-8 without any problems.
-
-Select *Synchronization & Storage*.
-
-Make sure that *Keep messages for this account on this computer* is unticked, then click *Ok*.
-
-Click on *Inbox*. Depending upon how much email you have it may take a while to import the subject lines.
-
-Note that when sending an email for the first time you will also need to accept the SSL certificate.
-
-Get into the habit of using email encryption and encourage others to do so. Remember that you may not think that your emails are very interesting but the Surveillance State is highly interested in them and will be actively trying to data mine your private life looking for "suspicious" patterns, regardless of whether you are guilty of any crime or not.
-
-**** Making folders visible
-By default you won't be able to see any folders which you may have created earlier using the /mailinglistrule/ script. To make folders visible select:
-
-*Menu*, hover over *Preferences*, select *Account Settings*, select *Server Settings* then click on the *Advanced* button.
-
-Make sure that "*show only subscribed folders*" is not checked. Then click the *ok* buttons. Folders will be re-scanned, which may take some time depending upon how much email you have, but your folders will then appear.
-*** Kmail
-Kmail doesn't work very well and so isn't recommended. In particular the inbox doesn't appear to be accessible via IMAP.
-
-When the account assistant screen appears enter your email address and user login.
-
-Account type: Generic IMAP Email Server
-Check /Download all messages for offline use/
-Enter a password for KDE Wallet
-When a certificate error appears click /Continue/ then accept /Forever/
-After "could not authenticate" click /Account settings/
-Select /General/ tab
-Change your account name, username and password
-Select the /Advanced/ tab
-Click on /Serverside Subscription/ and ensure that the relevant folders are checked
-Click /Finish/
-Click /Check Mail/

-
-*** Rules for mailing lists
-A common situation with email is that you may be subscribed to various mailing lists and want incoming email from those to be automatically grouped into a separate folder for each list.
-
-We can make a script to make adding mailing list rules easy:
-
-#+BEGIN_SRC: bash
-editor /usr/bin/mailinglistrule
-#+END_SRC
-
-Add the following:
-
-#+BEGIN_SRC: bash
-#!/bin/bash
-MYUSERNAME=$1
-MAILINGLIST=$2
-SUBJECTTAG=$3
-MUTTRC=/home/$MYUSERNAME/.muttrc
-PM=/home/$MYUSERNAME/.procmailrc
-LISTDIR=/home/$MYUSERNAME/Maildir/$MAILINGLIST
-if [ ! -d "$LISTDIR" ]; then
- mkdir -m 700 $LISTDIR
- mkdir -m 700 $LISTDIR/tmp
- mkdir -m 700 $LISTDIR/new
- mkdir -m 700 $LISTDIR/cur
-fi
-chown -R $MYUSERNAME:$MYUSERNAME $LISTDIR
-echo "" >> $PM
-echo ":0" >> $PM
-echo " * ^Subject:.*()\[$SUBJECTTAG\]" >> $PM
-echo "$LISTDIR/new" >> $PM
-chown $MYUSERNAME:$MYUSERNAME $PM
-if [ ! -f "$MUTTRC" ]; then
- cp /etc/Muttrc $MUTTRC
- chown $MYUSERNAME:$MYUSERNAME $MUTTRC
-fi
-PROCMAILLOG=/home/$MYUSERNAME/log
-if [ ! -d $PROCMAILLOG ]; then
- mkdir $PROCMAILLOG
- chown -R $MYUSERNAME:$MYUSERNAME $PROCMAILLOG
-fi
-#+END_SRC
-
-Save and exit, then make the script executable.
-
-#+BEGIN_SRC: bash
-chmod +x /usr/bin/mailinglistrule
-#+END_SRC
-
-Now we can add a new mailing list rule with the following, where /myusername/ is your username, /mailinglistname/ is the name of the mailing list (with no spaces) and /subjecttag/ is the tag which usually appears within square brackets in the subject line of emails from the list.
-
-#+BEGIN_SRC: bash
-mailinglistrule [myusername] [mailinglistname] [subjecttag]
-#+END_SRC
-
-Repeat this command for as many mailing lists as you need. Then edit your local Mutt configuration.
-
-#+BEGIN_SRC: bash
-editor /home/myusername/.muttrc
-#+END_SRC
-
-Search for the *mailboxes* variable and add entries for the mailing lists you just created. For example:
-
-#+BEGIN_SRC: bash
-mailboxes = =Sent =mailinglistname
-#+END_SRC
-
-Then save and exit.
-
-*** Rules for specific email addresses
-
-You can also make a script which will allow you to move mail from specific email addresses to a folder.
-
-#+BEGIN_SRC: bash
-editor /usr/bin/emailrule
-#+END_SRC
-
-Add the following:
-
-#+BEGIN_SRC: bash
-#!/bin/bash
-MYUSERNAME=$1
-EMAILADDRESS=$2
-MAILINGLIST=$3
-MUTTRC=/home/$MYUSERNAME/.muttrc
-PM=/home/$MYUSERNAME/.procmailrc
-LISTDIR=/home/$MYUSERNAME/Maildir/$MAILINGLIST
-if [ ! -d "$LISTDIR" ]; then
- mkdir -m 700 $LISTDIR
- mkdir -m 700 $LISTDIR/tmp
- mkdir -m 700 $LISTDIR/new
- mkdir -m 700 $LISTDIR/cur
-fi
-chown -R $MYUSERNAME:$MYUSERNAME $LISTDIR
-echo "" >> $PM
-echo ":0" >> $PM
-echo " * ^From: $EMAILADDRESS" >> $PM
-echo "$LISTDIR/new" >> $PM
-chown $MYUSERNAME:$MYUSERNAME $PM
-if [ ! -f "$MUTTRC" ]; then
- cp /etc/Muttrc $MUTTRC
- chown $MYUSERNAME:$MYUSERNAME $MUTTRC
-fi
-PROCMAILLOG=/home/$MYUSERNAME/log
-if [ ! -d $PROCMAILLOG ]; then
- mkdir $PROCMAILLOG
- chown -R $MYUSERNAME:$MYUSERNAME $PROCMAILLOG
-fi
-#+END_SRC
-
-Save and exit, then make the script executable.
-
-#+BEGIN_SRC: bash
-chmod +x /usr/bin/emailrule
-#+END_SRC
-
-Then to add a particular email address to a folder run the command:
-
-#+BEGIN_SRC: bash
-emailrule [myusername] [emailaddress] [foldername]
-#+END_SRC
-
-If you want any mail from the given email address to be deleted then set the /foldername/ to /Trash/.
-
-To ensure that the folder appears within Mutt.
-
-#+BEGIN_SRC: bash
-editor /home/myusername/.muttrc
-#+END_SRC
-
-Search for the *mailboxes* variable and add entries for the mailing lists you just created. For example:
-
-#+BEGIN_SRC: bash
-mailboxes = =Sent =foldername
-#+END_SRC
-
-Then save and exit.

-Wordpress is the most popular blogging platform, but in practice I found it to be high maintenance with frequent security updates and breakages. More practical for a home server is Flatpress. Flatpress doesn't use a MySql database, just text files, and so is easy to relocate or reinstall.

-#+END_SRC
-
-Connect to the IRC and identify yourself as an operator. Here /mynetwork/ should be the same as *network_name* specified earlier within /ircd.conf/. The network name is something equivalent to "freenode".
-
-#+BEGIN_SRC: bash
-/network add -nick mynick mynetwork
-
-/channel add -auto #mychannel mynetwork channelpassword

-
-/msg -servername chanserv set #mychannel mlock +k channelpassword
-
-/set paste_join_multiline OFF
-#+END_SRC
-
-If you edit the irssi config file:
-
-#+BEGIN_SRC: bash
-editor ~/.irssi/config
-#+END_SRC
-
-It should look something like this:
-
-#+BEGIN_SRC: bash
- {
- address = "mydomainname.com";
- chatnet = "mynetwork";
- port = "6697";
- password = "mysendacceptpassword";
- use_ssl = "yes";
- ssl_verify = "no";
- autoconnect = "yes";
- },
-#+END_SRC
-
-If you're not using a self-signed certificate (self-signed is the default) then you can set *ssl_verify* to "yes".
-
-By default irssi will use UTC time. An example of setting to some other time zone is as follows:
-
-#+BEGIN_SRC: bash
-echo "load perl" >> ~/.irssi/startup
-echo "script exec $ENV{'TZ'}='Europe/London';" >> ~/.irssi/startup
-#+END_SRC
-
-Also enable /Off The Record/ (OTR) messaging.
-
-#+BEGIN_SRC: bash
-echo "load otr" >> ~/.irssi/startup
-#+END_SRC
-
-By default Irssi does not look especially attractive. To improve it's looks:
-
-#+BEGIN_SRC: bash
-cd ~/.irssi
-wget http://freedombone.uk.to/irssi/xchat.theme
-mkdir ~/.irssi/scripts
-mkdir ~/.irssi/scripts/autorun

-*** Using irssi with Off The Record messaging (OTR)
-Once you're running irssi then you can enable OTR with:
-
-#+BEGIN_SRC: bash
-/statusbar window add otr
-/otr genkey mynick@network (for example mynick@irc.freenode.net)
-#+END_SRC

-
-And to trust or distrust someone else's fingerprint.
-
-#+BEGIN_SRC: bash
-/otr trust [fingerprint]
-/otr distrust [fingerprint]
-#+END_SRC
-
-*** Usage with XChat
-Within the network list click, *Add* and enter your domain name then click *Edit*.
-
-Select the entry within the servers box, then enter *mydomainname.com/6697* and press *Enter*.
-
-Uncheck *use global user information*.
-
-Enter first and second nicknames and check *auto connect to this network on startup*.
-
-Check *use SSL* and *accept invalid SSL certificate*.
-
-Enter some favourite channels and within *server password* enter /mysendacceptpassword/ which you defined earlier when setting up the server.
-
-Click *close* and then *connect*.
-*** Install Irssi as a daemon
-
-It may be useful to run a persistent Irssi session on the BBB. This will enable you to log in and see any entries which occurred previously so that you don't find yourself in an argument without knowledge of what was said in the last few minutes or hours. This feature only works for a single user on the BBB - typically the administrator.
-
-First install some prerequisites.

-
-It's possible to test that your XMPP server is working at https://xmpp.net. It may take several minutes and you'll get a low score because of the self-signed certificate, but it will at least verify that your server is capable of communicating.
-
-*** Managing users
-
-To add a user:
-
-#+BEGIN_SRC: bash
-prosodyctl adduser myusername@mydomainname.com
-#+END_SRC
-
-To change a user password:
-
-#+BEGIN_SRC: bash
-prosodyctl passwd myusername@mydomainname.com
-#+END_SRC
-
-To remove a user:
-
-#+BEGIN_SRC: bash
-prosodyctl deluser myusername@mydomainname.com
-#+END_SRC
-
-Report the status of the XMPP server:
-
-#+BEGIN_SRC: bash
-prosodyctl status
-#+END_SRC
-
-*** Using with Jitsi
-Jitsi is the recommended communications client for desktop or laptop systems, since it includes the /off the record/ (OTR) feature which provides some additional security beyond the usual SSL certificates.
-
-Jitsi can be downloaded from https://jitsi.org/
-
-On your desktop/laptop open Jitsi and select *Options* from the *Tools* menu.
-
-Click *Add* to add a new user, then enter the Jabber ID which you previously specified with /prosodyctl/ when setting up the XMPP server. Close and then you should notice that your status is "Online" (or if not then you should be able to set it to online).
-
-From the *File* menu you can add contacts, then select the chat icon to begin a chat. Click on the lock icon on the right hand side and this will initiate an authentication procedure in which you can specify a question and answer to verify the identity of the person you're communicating with. Once authentication is complete then you'll be chating using OTR, which provides an additional layer of security.
-
-When opening Jitsi initially you will get a certificate warning for your domain name (assuming that you're using a self-signed certificate). If this happens then select *View Certificate* and enable the checkbox to trust the certificate, then select *Continue Anyway*. Once you've done this then the certificate warning will not appear again unless you reinstall Jitsi or use a different computer.
-
-You can also [[https://www.youtube.com/watch?v=vgx7VSrDGjk][see this video]] as an example of using OTR.
-*** Using with Ubuntu
-The default XMPP client in Ubuntu is Empathy. Using Empathy isn't as secure as using Jitsi, since it doesn't include the /off the record/ feature, but since it's the default it's what many users will have easy access to.
-
-Open *System Settings* and select *Online Accounts*, *Add account* and then *Jabber*.
-
-Enter your username (myusername@mydomainname.com) and password.
-
-Click on *Advanced* and make sure that *Encryption required* and *Ignore SSL certificate errors* are checked. Ignoring the certificate errors will allow you to use the self-signed certificate created earlier. Then click *Done* and set your Jabber account and Empathy to *On*.
-*** Using with Android
-
-There are a few XMPP clients available on Android. Ideally choose ones which support off-the-record messaging. Here are some examples.
-
-**** Xabber
-Install [[https://f-droid.org/][F-Droid]]
-
-Search for and install Xabber.
-
-Add an account and enter your Jabber/XMPP ID and password.
-
-From the menu select *Settings* then *Security* then *OTR mode*. Set the mode to *Required*.
-
-Make sure that *Check server certificate* is not checked.
-
-Go back to the initial screen and then using the menu you can add contacts and begin chatting. Both parties will need to go through the off-the-record question and answer verification before the chat can begin, but that only needs to be done once for each person you're chatting with.
-
-**** Gibberbot
-Install [[https://f-droid.org/][F-Droid]]
-
-Search for and install Gibberbot, otherwise known as ChatSecure.
-
-From the menu open *Accounts*
-
-Select *Add account*
-
-Change the server port from 0 to 5222
-
-Done
-
-Accept unknown certificate? Select *Always*
-
-Go back to the initial screen and then using the menu you can add contacts and begin chatting.

-*** Friendica
-**** Installation
-
-See [[Setting up a web site]] for details of how to update a web server configuration for your Friendica site. You should have a separate domain name specifically to run Friendica on. It can't be installed in a subdirectory on a domain used for something else.
-
-Edit your web server configuration:
-
-#+BEGIN_SRC: bash
-editor /etc/nginx/sites-available/myfriendicadomainname.com
-#+END_SRC
-
-Replace the section which begins with "listen 80" with the following:
-
-#+BEGIN_SRC: bash
-server {
- listen 80;
- rewrite ^ https://$server_name$request_uri? permanent;
-}
-#+END_SRC
-
-Save and exit, then restart the web server.
-
-#+BEGIN_SRC: bash
-service nginx restart
-#+END_SRC
-
-Now install some dependencies.
-
-#+BEGIN_SRC: bash
-apt-get install mysql-server php5-common php5-cli php5-curl php5-gd php5-mysql php5-mcrypt php5-fpm php5-cgi php-apc
-#+END_SRC
-
-If you are installing /mysql-server/ for the first time then enter an admin password.
-
-Reduce the memory use of mysql by using the "small" configuration.
-
-#+BEGIN_SRC: bash
-cp /usr/share/doc/mysql-server-5.5/examples/my-small.cnf /etc/mysql/my.cnf
-#+END_SRC
-
-Create a mysql database, replacing /myfriendicapassword/ with a password used to administer the friendica database.
-
-#+BEGIN_SRC: bash
-mysql -u root -p
-create database friendica;
-CREATE USER 'friendicaadmin'@'localhost' IDENTIFIED BY 'myfriendicapassword';
-GRANT ALL PRIVILEGES ON friendica.* TO 'friendicaadmin'@'localhost';
-quit
-#+END_SRC
-
-You may need to fix Git SSL problems.
-
-#+BEGIN_SRC: bash
-git config --global http.sslVerify true
-apt-get install ca-certificates
-cd ~/
-editor .gitconfig
-#+END_SRC
-
-The .gitconfig file should look something like this:
-
-#+BEGIN_SRC: bash
-[user]
- name = yourname
- email = myusername@mydomainname.com
-[http]
- sslVerify = true
- sslCAinfo = /etc/ssl/certs/ca-certificates.crt
-#+END_SRC
-
-Get the source code.
-
-#+BEGIN_SRC: bash
-export HOSTNAME=myfriendicadomainname.com
-cd /var/www/$HOSTNAME
-rm -rf htdocs
-git clone https://github.com/friendica/friendica.git htdocs
-chmod -R 755 htdocs
-chown -R www-data:www-data htdocs
-chown -R www-data:www-data htdocs/view/smarty3
-git clone https://github.com/friendica/friendica-addons.git htdocs/addon
-#+END_SRC
-
-Now visit the URL of your site and you should be taken through the rest of the installation procedure.
-
-| Database Server Name | localhost |
-| Database login name | friendicaadmin |
-| Database Login Password | myfriendicapassword |
-| Database Name | friendica |
-
-When installation is complete if you already have an exported account which you wish to import then visit https://myfriendicadomain.com/uimport, rather than registering a new user.
-
-Install the poller.
-
-#+BEGIN_SRC: bash
-editor /etc/crontab
-#+END_SRC
-
-and append the following, changing /myfriendicadomainname.com/ to whatever your Friendica domain is.
-
-#+BEGIN_SRC: bash
-*/10 * * * * root cd /var/www/myfriendicadomainname.com/htdocs; /usr/bin/timeout 120 /usr/bin/php include/poller.php
-#+END_SRC
-
-Save and exit, then restart cron.
-
-#+BEGIN_SRC: bash
-service cron restart
-#+END_SRC
-
-You can improve the speed of Friendica database searches by adding the following indexes:
-
-#+BEGIN_SRC: bash
-mysql -u root -p
-use friendica;
-CREATE INDEX `uri_received` ON item(`uri`, `received`);
-CREATE INDEX `received_uri` ON item(`received`, `uri`);
-CREATE INDEX `contact-id_created` ON item(`contact-id`, created);
-CREATE INDEX `uid_network_received` ON item(`uid`, `network`, `received`);
-CREATE INDEX `uid_parent` ON item(`uid`, `parent`);
-CREATE INDEX `uid_received` ON item(`uid`, `received`);
-CREATE INDEX `uid_network_commented` ON item(`uid`, `network`, `commented`);
-CREATE INDEX `uid_title` ON item(uid, `title`);
-CREATE INDEX `created_contact-id` ON item(`created`, `contact-id`);
-quit
-#+END_SRC
-
-Make sure that Friendica doesn't use too much memory.
-
-#+BEGIN_SRC: bash
-editor /var/www/$HOSTNAME/htdocs/.htaccess
-#+END_SRC
-
-Append the following:
-
-#+BEGIN_SRC: bash
-php_value memory_limit 32M
-#+END_SRC
-
-The save ane exit.
-
-**** Backups
-
-Make sure that the database gets backed up. By using cron if anything goes wrong then you should be able to recover the database either from the previous day or the previous week.
-
-#+BEGIN_SRC: bash

-**** Recommended configuration
-***** Admin
-To get to the admin settings you will need to be logged in with the admin email address which you specified at the beginning of the installation procedure. Depending upon the theme which you're using "/admin/" will be available either as an icon or on a drop down menu.
-
-Under the *plugins* section the main one which you may wish to enable is the NSFW plugin. With that enabled if a post contans the #NSFW tag then it will appear minimised by default and you will need to click a button to open it.
-
-Under the *themes* section select a few themes, including mobile themes which are suitable for phones or tablets.
-
-Under the *site* section give your Friendica node a name other than "/my friend network/", you can change the icon and banner text and set the default mobile theme typically to /frost-mobile/. If you don't want your node to host a lot of accounts for people you don't know then you may want to set the register policy to "/requires approval/". For security it's probably a good idea only to host accounts for people who you actually know, rather than random strangers. Also be aware that the Beaglebone does not have a great deal of computational power or bandwidth and will not function well if there are hundreds of users using your node. If you're not federating with Diaspora or other sites then you may wish to select "/only allow Friendica contacts/". That improves the security of the system, since communication between Friendica nodes is always encrypted separately and in addition to the usual SSL encryption layer - which makes life interesting for the Surveillance State and at least keeps those cryptanalysts employed.
-
-If you also wish to publish your public posts to a Diaspora node then within the *site* settings select *enable Diaspora support*.
-
-It's probably a good idea to enable "/private posts by default for new users/" and also "/don't include post content in email notifications/". Since traditional email isn't a secure system and is easily vulnerable to attack by systems such as [[https://en.wikipedia.org/wiki/XKeyscore][Xkeyscore]].
-
-***** Settings
-Each user has their own customisable settings, typically available either via an icon or by an entry on a drop down menu.
-
-Under *additional features* enable "/richtext editor/", "/post preview/", "/group filter/", "/network filter/", "/edit sent posts/" and "/dislike posts/".
-
-Under *display settings* select your desktop and mobile themes.
-
-Once you have connected to enough friends it's also a good idea to use the "/export personal data/" option from here. This will save a file to your local system, which you can import into another friendica node if necessary.
-**** To access from an Android device
-***** App
-Open a browser on your device and go to https://f-droid.org/ then download and install the F-Droid apk. If you then open F-Droid you can search for and install the Friendica app.
-
-If you are using a self-signed certificate then at the login screen scroll down to the bottom, select the SSL settings then scroll down and disable SSL certificate checks. You will then be able to log in using https, which at least gives you some protection via the encryption.
-
-More information about the Friendica app can be found on http://friendica-for-android.wiki-lab.net/
-***** Mobile Theme
-Another way to access Friendica from a mobile device is to just use the web browser. If you have selected a mobile theme within your settings then when viewing from an Android system the mobile theme will be displayed.

-*** Red Matrix
-**** Introduction
-Red Matrix is the current version of the Friendica social networking system. It's more general than Friendica in that it's designed as a generic communication system based around a protocol called "zot". At the time of writing in early 2014 Red Matrix remains at an alpha stage of development and so it's not advised that you install it unless you're willing to put up with bugs and frustrations. In the large majority of cases it's better to stick with Friendica for now.
-
-**** Prerequisites
-The main problem with Red Matrix is that in order to install it you will need to have purchased a domain name (i.e. not a FreeDNS subdomain) and a SSL certificate for it.
-
-You could join some other Red Matrix server, but this suffers from "/The Levison Problem/" in which some goons show up with a gagging order demanding coppies of the SSL private key. In that scenario unless the owner of the server is exceptionally brave users may never be informed that the site has been compromised or that there is interception hardware attached to the server. Joining another server defeats the object of being digitally self-sufficient and raises legal question marks about the ownership of data which you might upload to a server which doesn't belong to you.
-
-**** Installation
-
-See [[Setting up a web site]] for details of how to update the Apache configuration for your Red Matrix site. You should have a separate domain name specifically to run Red Matrix on. It can't be installed in a subdirectory on a domain used for something else.
-
-Edit your Apache configuration and disable the port 80 (HTTP) version of the site. We only want to log into Red Matrix via HTTPS, so to prevent anyone from accidentally logging in insecurely:
-
-#+BEGIN_SRC: bash
-editor /etc/apache2/sites-available/mydomainname.com
-#+END_SRC
-
-Replace the section which begins with ** with the following:
-
-#+BEGIN_SRC: bash
-
- ServerAdmin myusername@mydomainname.com
- ServerName myredmatrixdomainname.com
-
- RewriteEngine On
- RewriteCond %{HTTPS} off
- RewriteRule (.*) https://%{HTTP_HOST}%{REQUEST_URI}
-
-#+END_SRC
-
-Save and exit, then restart the apache server.
-
-#+BEGIN_SRC: bash
-service apache2 restart
-#+END_SRC
-
-Now install some dependencies.
-
-#+BEGIN_SRC: bash
-apt-get install mysql-server php5-common php5-cli php5-curl php5-gd php5-mysql php5-mcrypt
-#+END_SRC
-
-Enter an admin password for MySQL.
-
-Reduce the memory use of mysql by using the "small" configuration.
-
-#+BEGIN_SRC: bash
-cp /usr/share/doc/mysql-server-5.5/examples/my-small.cnf /etc/mysql/my.cnf
-#+END_SRC
-
-Create a mysql database.
-
-#+BEGIN_SRC: bash
-mysql -u root -p
-create database redmatrix;
-CREATE USER 'redmatrixadmin'@'localhost' IDENTIFIED BY 'password';
-GRANT ALL PRIVILEGES ON redmatrix.* TO 'redmatrixadmin'@'localhost';
-quit
-#+END_SRC
-
-You may need to fix Git SSL problems.
-
-#+BEGIN_SRC: bash
-git config --global http.sslVerify true
-apt-get install ca-certificates
-cd ~/
-editor .gitconfig
-#+END_SRC
-
-The .gitconfig file should look something like this:
-
-#+BEGIN_SRC: bash
-[http]
- sslVerify = true
- sslCAinfo = /etc/ssl/certs/ca-certificates.crt
-[user]
- email = myusername@mydomainname.com
- name = yourname
-#+END_SRC
-
-Get the source code.
-
-#+BEGIN_SRC: bash
-export HOSTNAME=mydomainname.com
-mkdir /var/www/$HOSTNAME
-cd /var/www/$HOSTNAME
-rm -rf htdocs
-git clone https://github.com/friendica/red.git htdocs
-chmod -R 755 htdocs
-chown -R www-data:www-data htdocs
-mkdir htdocs/view/tpl/smarty3
-mkdir htdocs/store/[data]
-mkdir htdocs/store/[data]/smarty3
-chmod 777 htdocs/view/tpl
-chmod 777 htdocs/view/tpl/smarty3
-chmod 777 htdocs/store/[data]/smarty3
-git clone https://github.com/friendica/red-addons.git htdocs/addon
-#+END_SRC
-
-Now visit the URL of your site and you should be taken through the rest of the installation procedure. Note that this may take a few minutes so don't be concerned if it looks as if it has crashed - just leave it running. If you have trouble with "allow override" ensure that "AllowOverride" is set to "all" in your Apache settings for the site (within /etc/apache2/sites-available) and then restart the apache2 service.
-
-Install the poller.
-
-#+BEGIN_SRC
-editor /etc/crontab
-#+END_SRC
-
-and append the following, changing /mydomainname.com/ to whatever your domain is.
-
-#+BEGIN_SRC
-12,22,32,42,52 * * * * root cd /var/www/mydomainname.com/htdocs; /usr/bin/timeout 240 /usr/bin/php include/poller.php
-#+END_SRC
-
-Save and exit, then restart cron.
-
-#+BEGIN_SRC: bash
-service cron restart
-#+END_SRC
-
-**** Backups
-
-Make sure that the database gets backed up. By using cron if anything goes wrong then you should be able to recover the database either from the previous day or the previous week.
-
-#+BEGIN_SRC: bash
-editor /etc/cron.daily/backup
-#+END_SRC
-
-Uncomment the lines for Red Matrix, then save and exit. If you didn't install Friendica earlier then see the backup section within the Friendica install instructions.
-
-#+BEGIN_SRC: bash
-chmod 600 /etc/cron.daily/backup
-chmod +x /etc/cron.daily/backup
-editor /etc/cron.weekly/backup
-#+END_SRC
-
-If you already have a backup script created for Friendica then just uncomment the lines for Red Matrix. The backup script should look something like the following:
-
-#+BEGIN_SRC: bash
-#!/bin/sh
-
-umask 0077
-
-# Friendica
-cp -f /var/backups/friendica_weekly.sql /var/backups/friendica_2weekly.sql
-cp -f /var/backups/friendica_daily.sql /var/backups/friendica_weekly.sql
-
-# Red Matrix
-cp -f /var/backups/redmatrix_weekly.sql /var/backups/redmatrix_2weekly.sql
-cp -f /var/backups/redmatrix_daily.sql /var/backups/redmatrix_weekly.sql
-#+END_SRC
-
-Save and exit.
-
-#+BEGIN_SRC: bash
-chmod 600 /etc/cron.weekly/backup
-chmod +x /etc/cron.weekly/backup
-editor /etc/cron.monthly/backup
-#+END_SRC
-
-If you already have a backup script created for Friendica then just uncomment the lines for Red Matrix. The backup script should look something like the following:
-
-#+BEGIN_SRC: bash
-#!/bin/sh
-
-# Friendica
-cp -f /var/backups/friendica_monthly.sql /var/backups/friendica_2monthly.sql
-cp -f /var/backups/friendica_weekly.sql /var/backups/friendica_monthly.sql
-
-# Red Matrix
-cp -f /var/backups/redmatrix_monthly.sql /var/backups/redmatrix_2monthly.sql
-cp -f /var/backups/redmatrix_weekly.sql /var/backups/redmatrix_monthly.sql
-#+END_SRC
-
-Save and exit.
-
-#+BEGIN_SRC: bash
-chmod 600 /etc/cron.monthly/backup
-chmod +x /etc/cron.monthly/backup
-#+END_SRC
-
-**** To access from an Android device
-***** App
-Open a browser on your device and go to https://f-droid.org/ then download and install the F-Droid apk. If you then open F-Droid you can search for and install the Friendica app.
-
-If you are using a self-signed certificate then at the login screen scroll down to the bottom, select the SSL settings then scroll down and disable SSL certificate checks. You will then be able to log in using https, which at least gives you some protection via the encryption.
-
-More information about the Friendica app can be found on http://friendica-for-android.wiki-lab.net/

-*** pump.io
- :PROPERTIES:
- :ORDERED: t
- :END:
-
-pump.io is the successor to StatusNet (which later became [[GNU Social]]) and is a communications system which can do things other than just microblogging. It takes fewer system resources to run and so is better suited to low power servers such as the BBB, but is more complicated to install. pump.io doesn't work well with self-signed SSL certificates so this may be something which you can only use if you have your own domain and an "authority" issued certificate. Using a self-signed certificate you can only use pump.io as a /data silo/ which won't federate with other servers.
-
-For a pump.io site you will need a separate domain/subdomain, so see [[Setting up a web site]] for details of how to create an Apache configuration for your site. If you're using freedns then you will need to create a new subdomain.

-
-Now visit your pump.io site by navigating to:
-
-https://mypumpiodomainname.com
-
-and add a new user. If you wish this to be a single user node not open to the general public (including spammers and sockpuppets) then edit */etc/pump.io.json* and set *disableRegistration* to *true*. After making that change restart with the command *service pumpio restart*.
-
-Once you've set up your user account it's recommended that you don't use the web based user interface and instead use a native client such as [[http://jancoding.wordpress.com/dianara/][Dianara]] or Pumpa. On Ubuntu you can install these via the Software Center. On mobile devices you can install AndStatus via F-Droid.
-
-A list of pump.io sites can be found at http://pumpstatus.jpope.org. At the time of writing there isn't any public directory and so finding people to follow is really a question of navigating through lists of /following/ or /followers/ (rather like the web before search engines were invented).
-
-Ensure that data data gets backed up with:
-
-#+BEGIN_SRC: bash
-printf "\n\n# Redis backup" >> /etc/cron.daily/backup

-#+END_SRC
-
-At the time of writing creating backups of the pump.io database is critically important, because regenerating the database or moving to a different databank type causes you to be /permanently banned/ from the pump.io network unless you change your domain name (which may not always be an available option).

-** Install Gopher
-*** Server setup
-
-Gopher is an old internet protocol which originated a few years before the web and is purely text based. It can be quite fun to build a gopher site and browse the gopherverse. One thing to keep in mind is that there is no security with gopher, so any text transmitted is trivially interceptable by systems such as [[https://en.wikipedia.org/wiki/XKeyscore][Xkeyscore]] or deep packet inspection.
-
-To set up a gopher server:
-
-#+BEGIN_SRC: bash
-apt-get install build-essential
-mkdir ~/build
-cd ~/build
-wget http://freedombone.uk.to/geomyidae-current.tgz
-#+END_SRC
-
-Verify the download:
-
-#+BEGIN_SRC: bash

-*** A new kind of Email
-[[https://bitmessage.org][Bitmessage]] is a new type of messaging system intended to fulfill the same role as email, but without the security problems. In particular, Bitmessage attempts to not just encrypt the content but also the metadata. It's message broadcasting system makes it exceedingly difficult for an attacker to know which computer a message is destined for. The only way you know whether a message has been sent to you is whether you are able to decrypt it from the passing stream of messages.
-
-Although similar to Bitcoin in some regards, such as "/proof of work/", Bitmessage has no block chain and messages are only buffered for approximately three days after which they are deleted from any given node.
-
-Installing Bitmessage as a daemon will increase the size of the network, and therefore the level of security for all users.
-

-Now open port 8444 on your internet router or firewall and direct it to the BBB.
-
-*** Using Bitmessage
-Although in principle it would be possible to send Bitmessages directly from the BBB, in practice the /proof of work/ requirement would mean that it would take an infeasibly long time to send messages, and the computational workload would likely greatly impair the performance of other services also running on the system. So to send and receive Bitmessages it's better to just install the client on a laptop or desktop machine.
-
-The easiest way to install the client is either to download it from [[https://bitmessage.org][bitmessage.org]] or to get the latest build from Github as follows:
-
-#+BEGIN_SRC: bash
-mkdir ~/build
-cd ~/build
-git clone https://github.com/Bitmessage/PyBitmessage.git
-cd PyBitmessage
-make install
-pybitmessage
-#+END_SRC
-
-*** Connect Bitmessage to Email
-
-It may be convenient to have any Bitmessages addressed to you which arrive at the BBB to be transfered to your email, so that you can check for messages on mobile devices or on computers where installing a Bitmessage client isn't an available option. This transference will take place on the BBB itself, so will not involve transmitting any plaintext over the local network or internet. To do this first you'll need to set up a receiving Bitmessage address by editing:
-
-#+BEGIN_SRC: bash
-/home/bitmsg/.config/PyBitmessage/keys.dat

-
-In some environments, such as behind corporate firewalls or under regimes hostile towards the idea of open access to knowledge and information you may find that you're not able to use tools such as /ssh/ to get access to the BBB. In the worst case all ports other than 80 and 443 may be blocked.
-
-In that scenario you can use a tool called [[http://code.google.com/p/shellinabox/][shellinabox]] to log into your BBB via your web site rather than via a terminal. This means that you can administrate your system from any device which has a web browser and keyboard.

-*** Private (encrypted) mailing list
-In addition to conventional public email lists it's also possible to set up a private mailing list which is only readable by members. A private email list uses [[https://en.wikipedia.org/wiki/GNU_Privacy_Guard][GPG]] and a public/private key pair for the server which can then be used to send emails to the list in an encrypted form. The email addresses and public GPG keys of members may be added to the list so that any new messages can be distributed to them in a secure manner.
-
-Private mailing lists are likely to be able to keep the contents of the discussion out of the clutches of warrantless mass surveillance but, as with all conventional email, it won't prevent such systems from generating social graphs of who is communicating with the list since the /from/ and /to/ attributes are always transmitted in the clear.
-

-**** Importing the public key of the mailing list
-Before you can use the mailing list you will first need to import its public key. How you do this depends upon which email client you're using.
-
-***** Using Mutt
-Send an email to /mailinglistname-sendkey@mydomainname.com/ to have the list public key emailed to you.
-
-When you receive the email open it and press *CTRL-k* to import it.
-***** Using Thunderbird
-Send an email to /mailinglistname-sendkey@mydomainname.com/ to have the list public key emailed to you.
-
-When you receive the email open it, select all the text with *CTRL-a* then *CTRL-c*.
-
-On the menu select *OpenPGP* followed by *Key Management*.
-
-You will now see a new menu bar. Select *Edit* followed by *Import keys from clipboard*.
-
-Click on *Import* followed by *Ok*.
-**** Using the list
-To obtain the public keys of list members send an email to /mailinglistname-request@mydomainname.com/ containing *X-LIST-KEYS* in the message body.
-
-To add a member: *X-ADD-MEMBER: othermember@otherdomain.net*
-
-An example of adding a public key to the list:
-
-#+BEGIN_SRC: bash
-X-ADD-KEY:

-
-To delete a member: *X-DELETE-MEMBER: othermember@otherdomain.net*
-
-To delete a public key: *X-DELETE-KEY: keyID*
-
-You can unsubscribe from the list with *X-UNSUBSCRIBE* in the message body.
-
-*** Decentralised mailing list
-A disadvantage with encrypted mailing lists which use the conventional email system is that there is a single server on which the list resides, and this creates a single point of failure and a bandwidth bottleneck for more heavily subscribed lists. If the mailing list server goes down for whatever reason then that may cause a lot of disruption to its users.
-
-An alternative is to use a decentralised mailing list, implemented using Bitmessage. On your local machine (not the BBB) you can make a private mailing list which is difficult to censor and where there is no single point of failure. This type of mailing list is known as a "/chan/".
-
-With Bitmessage if any one computer goes offline then the conversation can still keep going since there is no central mailing list server. Bitmessages are also encrypted with public/private key pairs and the manner in which the system operates makes it very difficult for the surveillance apparatus to exfiltrate the social graph of list users.
-
-On a Debian based system:
-
-#+BEGIN_SRC: bash
-sudo apt-get install makepasswd
-#+END_SRC
-
-or on an RPM based system:
-
-#+BEGIN_SRC: bash
-sudo yum install makepasswd
-#+END_SRC
-
-Create a name for your mailing list. This will be a random string.
-
-#+BEGIN_SRC: bash
-makepasswd -c 40
-#+END_SRC
-
-Keep a note of this.
-
-Run the Bitmessage client and on the menu select *File/Join-Create Chan/Create new chan*
-
-Enter the random string which you created as the name of the mailing list. Also take a note of the BM address which is created.
-
-You can hand out the random string used to generate the mailing list and its corresponding BM address to fellow members, either within a bitmessage or on paper or via [[https://en.wikipedia.org/wiki/Sneakernet][sneakernet]] or in a GPG/PGP encrypted email or via an XMPP+OTR or Friendica private message. Once others have those two pieces of data then they will be able to join.
-
-To make the list easier to identify, rather than just appearing as a random string, then under the *Your Identities* tab right click on it and select *Set Avatar* and assign a suitable icon.
-
-The disadvantage of this type of mailing list is that it's not possible for any one participant to act as a list moderator, or in other words each participant must do their own moderation. That's ok if the size of the group is small, but if it's larger then anyone spamming or trolling the list can make things miserable for the others.

-** Install Mediagoblin
-
-#+BEGIN_VERSE
-/The silos that are the main current points of media sharing are not only vulnerable to attacks on free speech, but also hamper important grassroots economic activity by privileging the interests of a tiny minority over those of most of the world./
-#+END_VERSE
-
-Mediagoblin allows you to have a YouTube/Soundcloud/Flickr/Picasa type of site to share your pictures, videos or audio files. An advantage of not having any company in the middle is that you can't be arbitrarily censored without any explanation, as seems to frequently occur on YouTube. It is recommended that you use media formats which are not encumbered by patents, such as /ogg/ or /ogv/.
-
-For a mediagoblin site it is recommended to use a separate domain/subdomain, so see [[Setting up a web site]] for details of how to create an Apache configuration for your microblog. If you're using freedns then you will need to create a new subdomain.
-
-Install some dependencies.

-** Subsonic music server
-
-#+BEGIN_VERSE
-/Where words fail, music speaks./
-
--- Hans Christian Andersen
-#+END_VERSE
-
-*** Introduction
-Owncloud is probably the easiest way to handle your media, but Subsonic is another alternative and has a mobile app which can be used to conveniently play your music. Unless you particularly prefer Subsonic it's probably better to stick with Owncloud and skip this section. Another limitation of Subsonic is that it requires Java, which uses a lot of RAM, so it may be better to only install it on systems with 1GB or more of memory and also increases the [[https://en.wikipedia.org/wiki/Attack_surface]["attack surface"]].
-
-The method of installing Subsonic described here is not ideal, but works. The main issue is that the Debian package supplied from sourceforge contains a licensing [[https://www.fsf.org/blogs/community/antifeatures][antifeature]], which needs to be removed in order to achieve a fully free system.
-*** Installing the Server
-For this you will need a new subdomain (or your own domain), so see [[Setting up a web site]] for details of how to do that.
-
-#+BEGIN_SRC: bash
-apt-get install openjdk-7-jre openjdk-7-jdk lintian maven libav-tools
-adduser subsonic
-mkdir ~/build
-cd ~/build
-wget http://freedombone.uk.to/subsonic-4.9.deb
-sha256sum subsonic-4.9.deb
-064c2a7e69d47715ce230f3dfcacdc627c18f6466e0fe48952f133ce06be698d
-dpkg -i subsonic-4.9.deb
-#+END_SRC
-
-Now we remove the antifeature by compiling from source and then overwriting the relevant files.
-
-#+BEGIN_SRC: bash
-git clone https://github.com/EugeneKay/subsonic.git
-cd subsonic
-git checkout release

-#+END_SRC
-
-*** Configuration
-Open a browser and go to your subsonic domain name. Log in with username /admin/ and password /admin/, then change your administrator password.
-
-Still logged in as the administrator, click /settings/ and select /transcoding/. Change the transcoding settings to the following:
-
-
-| Name | Convert from | Convert to | Step 1 |
-|----------------+---------------------------------------------------+------------+------------------------------------------------------------------------------------------------------------------------------------------|
-| mp3 audio | ogg oga aac m4a flac wav wma aif aiff ape mpc shn | mp3 | avconv -i %s -b %bk -q 0 -loglevel error -f mp3 - |

-
-Then save.
-
-Within the settings click on /users/ and add a user. Give your user access to everything by ticking all the checkboxes. You can then log out and log back in as the user.
-
-Open port 4040 on your internet router and forward it to the BBB.
-
-*** Adding your music
-The easiest way to add your music is to obtain a large capacity USB stick, copy your music onto it, plug it into the front of the BBB and then mount it as a drive.
-
-So with the USB stick plugged in and logged into the BBB as root via ssh:
-
-#+BEGIN_SRC: bash
-editor /usr/bin/attach-music
-#+END_SRC
-
-Add the following:
-
-#+BEGIN_SRC: bash
-#!/bin/bash
-if [ ! -d /var/music ]; then
- mkdir /var/music
-fi
-mount /dev/sda1 /var/music
-chown root:root /var/music
-chown -R subsonic:subsonic /var/music/*
-#+END_SRC
-
-Save and exit
-
-#+BEGIN_SRC: bash
-chmod +x /usr/bin/attach-music
-#+END_SRC
-
-Then just typing "attach-music" on the command line will mount the USB drive.
-
-Then within a browser go to your Subsonic domain name, log in as the administrator, select *settings*, then *Media folders* then *Scan media folders now*. Depending upon how much music you have this could take a while, so don't be too impatient. WHen It's complete you can log out and log back in as a user.
-
-*** Android App
-Within [[https://f-droid.org/][F-Droid]] search for *Dsub* and install it.
-
-Open the app, then press on the Dsub icon (top left) and select *settings*, followed by *servers*. Select one of the unused servers then set the name to your domain name, the server address to https://mysubsonicdomainname.com (the domain name you used for subsonic) and your username and password for the Subsonic user which you created earlier. Press on *test server* to check the internet connection to the BBB.
-
-Remove any other servers (including the demo) by pressing on them then selecting *remove server*.
-
-You can then press *back* a few times to return to the main Dsub menu and press *recently added*. If your media library has been scanned (as in the earlier "adding your music" step) then you should see tracks appear. Press on one, then press the play button.
-
-Other proprietary Subsonic mobile apps are available, but are not recommended. Anything proprietary could contain backdoors, malware or other nasties which merely assist the surveillance apparatus.
-** Database maintenance
-
-#+BEGIN_VERSE
-/To be ready to fail is to be prepared for success./
-
--- Jose Bergamin
-#+END_VERSE
-
-Ideally the system should be as close to "/install and forget/" as possible, but sometimes mysql databases can become corrupted. To handle that situation we can set up a script to monitor the databases and automatically try to repair them, and if the repair fails then to roll back to the previous day's backup, so that at most you may have lost one day of social media updates, rather than losing everything.

-#+BEGIN_SRC: bash

-** Messaging security
-If you're connected to other friends via Friendica then the preferred way to send private messages is via Friendica's built-in messaging system. This is a lot more convenient than using GPG with ordinary email and yet still provides a similar level of protection from unwarranted interception.
-** Moving Domains
-If you're moving servers and using a different domain name or path then you can search and replace URLs within files in the following way:
-
-#+BEGIN_SRC: bash
-find /var/www/mynewdomain/htdocs -type f -exec sed -i 's@myolddomain@mynewdomain@g' {} \;
-#+END_SRC
-
-If you're moving the blog to a new domain then you will need to delete the lock file:
-
-#+BEGIN_SRC: bash
-rm /var/www/myblogdomainname.com/htdocs/fp-content/%%setup.lock
-#+END_SRC
-
-Then visit your blog and reinstall it. Your existing content will be unaffected but you will need to delete the welcome post which gets added and also re-select your chosen theme.
-
-If you need to import blog posts from another blog then copy the *fp-content/content* directory from the old blog to the new blog, then within the admin panel select *maintain* and *rebuild index*.

-mysql -u root
-use mysql;
-update user set password=PASSWORD("mynewpassword") where User='root';
-flush privileges;
-quit
-/etc/init.d/mysql stop
-/etc/init.d/mysql start
-#+END_SRC
-*** Repair and optimize databases
-To check, repair and optimize the databases.
-
-#+BEGIN_SRC: bash

-mysqlcheck -u root -p --auto-repair --all-databases
-mysqlcheck -u root -p -o --all-databases
-#+END_SRC
-*** Backup all databases
-To back up all mysql databases:
-
-#+BEGIN_SRC: bash
-mysqldump -u root -p --all-databases --events > /var/backups/databasebackup.sql
-#+END_SRC
-*** Restoring a particular mysql database
-To restore yesterday's friendica backup:
-
-#+BEGIN_SRC: bash
-mysql -u root -p friendica -o < /var/backups/friendica_daily.sql
-#+END_SRC
-
-To restore the webmail database:
-
-#+BEGIN_SRC: bash
-mysql -u root -p roundcubemail -o < /var/backups/roundcubemail_daily.sql
-#+END_SRC
-
-To restore yesterday's Red Matrix backup:
-
-#+BEGIN_SRC: bash
-mysql -u root -p redmatrix -o < /var/backups/redmatrix_daily.sql
-#+END_SRC
-*** Removing and reinstalling mysql server
-
-Sometimes the mysql database may get completely messed up, and running /service mysql start/ may always fail with nothing reported in the logs. So if you manage to get into that unfortinate situation then you can fully remove mysql and reinstall it as follows:
-
-#+BEGIN_SRC: bash
-ps aux | grep mysql
-#+END_SRC
-
-and use /kill -9 / to kill all mysql processes.
-
-#+BEGIN_SRC: bash
-apt-get remove --purge mysql\*
-rm -rf /etc/mysql
-rm -rf /var/lib/mysql
-apt-get clean
-updatedb
-#+END_SRC
-
-Reinstall mysql:
-
-#+BEGIN_SRC: bash
-apt-get install mysql-server php5-common php5-cli php5-curl php5-gd php5-mysql php5-mcrypt php5-fpm php5-cgi php-apc
-#+END_SRC
-
-Then to recreate the Friendica and webmail databases:
-
-#+BEGIN_SRC: bash
-mysql -p
-create database friendica;
-CREATE USER 'friendicaadmin'@'localhost' IDENTIFIED BY 'myfriendicapassword';
-GRANT ALL PRIVILEGES ON friendica.* TO 'friendicaadmin'@'localhost';
-create database roundcubemail;
-CREATE USER 'roundcube'@'localhost' IDENTIFIED BY 'roundcubepassword';
-GRANT ALL PRIVILEGES ON roundcubemail.* TO 'roundcube'@'localhost';
-quit
-mysql -u root -p friendica -o < /var/backups/friendica_daily.sql
-mysql -u root -p roundcubemail -o < /var/backups/roundcubemail_daily.sql
-#+END_SRC
-
-And if you previously had Red Matrix installed:
-
-#+BEGIN_SRC: bash
-mysql -p
-create database redmatrix;
-CREATE USER 'redmatrixadmin'@'localhost' IDENTIFIED BY 'myredmatrixpassword';
-GRANT ALL PRIVILEGES ON redmatrix.* TO 'redmatrixadmin'@'localhost';
-quit
-mysql -u root -p redmatrix -o < /var/backups/redmatrix_daily.sql
-#+END_SRC
-
-Since IMAP seems entangled with mysql it may also be necessary to reinstall Exim and Dovecot.
-
-#+BEGIN_SRC: bash
-apt-get remove --purge exim4\*
-#+END_SRC
-
-Then follow the instructions in [[Install Email]], [[Spam filtering]] and [[Install Dovecot]].
-** Regenerating SSL certificates
-If a security vulnerability arrises which requires you to regenerate your SSL certificates, such as [[http://filippo.io/Heartbleed]["heartbleed"]], then this can be done as follows:
-
-Obtain the latest updates:
-
-#+BEGIN_SRC: bash
-apt-get update
-apt-get upgrade
-#+END_SRC
-
-Run *makecert * for each of your sites.
-
-Recreate the XMPP certificate:
-
-#+BEGIN_SRC: bash
-makecert xmpp
-chown prosody:prosody /etc/ssl/private/xmpp.key
-chown prosody:prosody /etc/ssl/certs/xmpp.*
-#+END_SRC
-
-And regenerate the IRC server keys:
-
-#+BEGIN_SRC: bash
-makecert ircd
-mv /etc/ssl/private/ircd.key /home/ircserver/ircd/ssl/
-mv /etc/ssl/certs/ircd.crt /home/ircserver/ircd/ssl/ircd.pem
-mv /etc/ssl/certs/ircd.dhparam /home/ircserver/ircd/ssl/dhparam.pem
-chmod 640 /home/ircserver/ircd/ssl/*
-chown -R ircserver:ircserver /home/ircserver/ircd
-chown -R ircserver:ircserver /home/ircserver/services
-chown -R ircserver:ircserver /home/ircserver/ircd/ssl
-#+END_SRC
-
-Regenerate email certificate.
-
-#+BEGIN_SRC: bash
-makecert exim
-mv /etc/ssl/private/exim.key /etc/exim4
-mv /etc/ssl/certs/exim.crt /etc/exim4
-mv /etc/ssl/certs/exim.dhparam /etc/exim4
-chown root:Debian-exim /etc/exim4/exim.key /etc/exim4/exim.crt /etc/exim4/exim.dhparam
-chmod 640 /etc/exim4/exim.key /etc/exim4/exim.crt /etc/exim4/exim.dhparam
-#+END_SRC
-
-As an added precaution you may wish to regenerate your ssh host keys:
-
-#+BEGIN_SRC: bash
-rm /etc/ssh/ssh_host_*
-dpkg-reconfigure openssh-server
-#+END_SRC
-
-Then reboot the server with:

-** Using your own domain
-Suppose that you have bought a domain name (rather than using a free subdomain on freedns) and you want to use that instead.
-
-Remove any existing nameservers for your domain (or select "custom" nameservers), then add:
-
-#+BEGIN_SRC: bash
-NS1.AFRAID.ORG
-NS2.AFRAID.ORG
-NS3.AFRAID.ORG
-NS4.AFRAID.ORG
-#+END_SRC
-
-It might take a few minutes for the above change to take effect. Within freedns click on "Domains" and add your domains (this might only be available to paid members). Make sure that they're marked as "private".
-
-Select "Subdomains" from the menu on the left then select the MX entry for your domain and change the destination to *10:mydomainname* rather than *10:mail.mydomainname*.
-
-To route email to one of your freedns domains:
-
-#+BEGIN_SRC: bash
-editor /etc/mailname
-#+END_SRC
-
-Add any extra domains which you own, then save and exit.
-
-#+BEGIN_SRC: bash
-editor /etc/exim4/update-exim4.conf.conf
-#+END_SRC
-
-Within dc_other_hostnames add your extra domain names, separated by a colon ':' character.
-
-Save and exit, then restart exim.
-
-#+BEGIN_SRC: bash
-update-exim4.conf.template -r
-update-exim4.conf
-service exim4 restart
-#+END_SRC
-
-You should now be able to send an email from /postmaster@mynewdomainname/ and it should arrive in your inbox.
-
-** Obtaining an "official" SSL certificate
-You can obtain a free "official" (as in recognised by default by web browsers) SSL certificate from [[https://www.startssl.com/][StartSSL]]. You will first need to have bought a domain name, since it's not possible to obtain one for a freedns subdomain, so see [[Using your own domain]] for details of how to do that. You should also have tested that you can send email to the domain and receive it on the BBB (via Mutt or any other email client).
-
-When creating a SSL certificate it's important that the private key (the private component of the public/private pair in [[https://en.wikipedia.org/wiki/Public-key_cryptography][public key cryptography]]) be generated on the BBB /and remain there/. Don't generate the private key via the StartSSL certificate wizard because this means that potentially they may retain a copy of it which could then be exfiltrated either via [[https://en.wikipedia.org/wiki/Lavabit][Lavabit]] style methodology, "implants", compromised sysadmins or other "side channel" methods. So that the private key isn't broadcast on the internet we can instead generate a certificate request, which is really just a request for authorisation of a public key.
-
-Firstly you should have a web server site configuration ready to go. See [[Setting up a web site]] for details.
-
-Within StartSSL under the validations wizard validate your domain, which means sending an email to it and confirming a code.
-
-Now we can generate the certificate request as follows.
-
-#+BEGIN_SRC: bash
-export HOSTNAME=mydomainname.com
-openssl genrsa -out /etc/ssl/private/$HOSTNAME.key 2048
-chown root:ssl-cert /etc/ssl/private/$HOSTNAME.key
-chmod 440 /etc/ssl/private/$HOSTNAME.key
-mkdir /etc/ssl/requests
-#+END_SRC
-
-Now make a certificate request as follows. You should copy and paste the whole of this, not just line by line.
-
-#+BEGIN_SRC: bash
-openssl req -new -sha256 -key /etc/ssl/private/$HOSTNAME.key -out /etc/ssl/requests/$HOSTNAME.csr
-#+END_SRC
-
-For the email address it's a good idea to use postmaster@mydomainname.
-
-Use a random 20 character password, and keep a note of it. We'll remove this later.
-
-View the request with:
-
-#+BEGIN_SRC: bash
-cat /etc/ssl/requests/$HOSTNAME.csr
-#+END_SRC
-
-You can then click on "skip" within the StartSSL certificates wizard and copy and paste the encrypted request into the text entry box. A confirmation will be emailed back to you normally within a few hours.
-
-Log into your StartSSL account and select *Retrieve Certificate* from the *Tool Box* tab. Copy the text.
-
-#+BEGIN_SRC: bash
-editor /etc/ssl/certs/$HOSTNAME.crt
-#+END_SRC
-
-Paste the public key, then save and exit. Then on the BBB.
-
-#+BEGIN_SRC: bash
-mkdir /etc/ssl/roots
-mkdir /etc/ssl/chains
-wget "http://www.startssl.com/certs/ca.pem" --output-document="/etc/ssl/roots/startssl-root.ca"
-wget "http://www.startssl.com/certs/sub.class1.server.ca.pem" --output-document="/etc/ssl/chains/startssl-sub.class1.server.ca.pem"
-wget "http://www.startssl.com/certs/sub.class2.server.ca.pem" --output-document="/etc/ssl/chains/startssl-sub.class2.server.ca.pem"
-wget "http://www.startssl.com/certs/sub.class3.server.ca.pem" --output-document="/etc/ssl/chains/startssl-sub.class3.server.ca.pem"

-#+END_SRC
-
-To avoid any possibility of the certificates being accidentally overwritten by self-signed ones at a later date you can create backups.
-
-#+BEGIN_SRC: bash

-mkdir /etc/ssl/backups/certs
-mkdir /etc/ssl/backups/private
-cp /etc/ssl/certs/$HOSTNAME* /etc/ssl/backups/certs/
-cp /etc/ssl/private/$HOSTNAME* /etc/ssl/backups/private/
-chmod -R 400 /etc/ssl/backups/certs/*
-chmod -R 400 /etc/ssl/backups/private/*
-#+END_SRC
-
-Remove the certificate password, so if the server is rebooted then it won't wait indefinitely for a non-existant keyboard user to type in a password.
-
-#+BEGIN_SRC: bash
-openssl rsa -in /etc/ssl/private/$HOSTNAME.key -out /etc/ssl/private/$HOSTNAME.new.key
-cp /etc/ssl/private/$HOSTNAME.new.key /etc/ssl/private/$HOSTNAME.key
-shred -zu /etc/ssl/private/$HOSTNAME.new.key
-#+END_SRC
-
-Create a bundled certificate which joins the certificate and chain file together.
-
-#+BEGIN_SRC: bash
-cat /etc/ssl/certs/$HOSTNAME.crt /etc/ssl/chains/startssl-sub.class1.server.ca.pem > /etc/ssl/certs/$HOSTNAME.bundle.crt
-#+END_SRC
-
-And also add it to the overall bundle of certificates for the BBB. This will allow you to easily install the certificates onto other systems.
-
