After the system has installed a README file will be generated which contains passwords and some brief advice on using the installed systems. You can read this with the following commands:
#+BEGIN_SRC bash
ssh username@domainname -p 2222
emacs ~/README
#+END_SRC
You should transfer any passwords to a password manager such as [[http://www.keepassx.org/][KeepassX]] and then delete them from the README file. To save the file after removing passwords use *CTRL-x CTRL-s*.
To exit you can either just close the terminal or use *CTRL-x CTRL-c* followed by the *exit* command.
Select /Manage Users/ then /Change user ssh public key/. Copy and paste the public key here, then exit.
It's a good idea to also copy the contents of *~/.ssh/id_rsa* and *~/.ssh/id_rsa.pub* to you password manager, together with the private key password if you created one.
There are advantages and disadvantages to using ssh keys for logins. The advantage is that this is much more secure than a memorised password, but the disadvantage is that you need to carry your ssh keys around and be able to install them on any computer of mobile device that you use. In high security or hostile infosec environments it may not be possible to carry or use USB thumb drives containing your keys and so memorised passwords may be the only available choice.
If you wish to only use ssh keys then log in to the Freedombone, become the root user and open the control panel with the 'control' command. Select /Security Settings/ then keep hitting enter until you reach the question about allowing password logins. Select "no" for that, then apply the settings. Any subsequent attempts to log in via a password will then be denied.
Within a browser go to your owncloud domain, then create an administrator account. The username and password can be anything, and ideally should be generated from a password manager.
You will also need to enter database details:
| Owncloud database user | owncloudadmin |
| Owncloud database password | See the [[Readme]] file |
| Owncloud database name | owncloud |
After creating an administrator account then create a user account via the Users dropdown menu entry on the right hand side and log the details in a password manager. Give the user a quota suitable for the size of your microSD card or other storage.
Log out from the administrator account and then log back in as the user you just created.
** On Android
Within F-droid search for *owncloud* and install the client. Also install *CalDAV Sync Adapter*.
Open the owncloud app and enter your owncloud domain name (including the https prefix) and login details for the user you created.
Open the calendar app (S planner) and under *settings* select *Calendars* then *Add account* then *CalDAV Sync Adapter*. Enter your owncloud username and password and the following URL:
An easy way to play music on any mobile device in your home is to use the DLNA service. Copy your music into a directory called "/Music/" on a USB thumb drive and then insert it into from socket on the Beaglebone.
ssh into the system with:
#+BEGIN_SRC bash
ssh myusername@mydomain.com -p 2222
#+END_SRC
Then mount the USB drive with:
#+BEGIN_SRC bash
su
attach-music
#+END_SRC
The system will scan the Music directory, which could take a while if there are thousands of files, but you don't need to do anything further with the Beaglebone other than perhaps to log out by typing *exit* a couple of times.
If you have an Android device then go to F-Droid (if you don't already have it installed then it can be [[https://f-droid.org/][downloaded here]]) and search for *ControlDLNA*. On running the app you should see a red Debian icon which you can press on, then you may need to select "local". After a few seconds the list of albums or tracks should then appear and you can browse and play them.
The DLNA service will only work within your local home network, and isn't remotely accessible from other locations via the internet. That can be both a good and a bad thing. Another consideration is that there are no access controls on DLNA services, so any music or videos on the USB drive will be playable by anyone within your home network. If you need to restrict access to certain files then it may be better to use the music player within Owncloud.
** With Owncloud
The main advantage of playing music via Owncloud is that you can do that from anywhere - not only within your home network.
By default a music player is installed into Owncloud, so all you need to do is to visit your Owncloud web site, select the *music* directory and then upload some music files. Afterwards you can select the *music icon* from the top left drop down menu and albums will then appear which can be played. If you want to share music with other users then you can select the *share* option from within the files view to make the tracks available.

When the install is complete you will see a lot of warnings but just ignore those and navigate to your microblog domain and you can then complete the configuration via the *Admin* section on the header bar. Some recommended admin settings are:
| Site settings | Text limit 140, Dupe Limit 60000 |
You will need to have a non self-signed SSL certificate in order to use Hubzilla. Put the public certificate in */etc/ssl/certs/yourhubzilladomainname.crt* and the private certificate in */etc/ssl/private/yourhubzilladomainname.key*. If there is an intermediate certificate needed (such as with StartSSL) then this will need to be concatenated onto the end of the crt file, like this:
Visit the URL of your Hubzilla 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.
IRC is useful for multi-user chat. The classic use case is for software development where many engineers might need to coordinate their activities, but it's also useful for meetings, parties and general socialising.
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 (username@domainname) 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*.
Tor Messenger is a messaging client which supports XMPP, and its onion routing enables you to protect the metadata of chat interactions to some extent by making it difficult for an adversary to know which server is talking to which. You can download Tor Messenger from [[https://torproject.org][torproject.org]] and the setup is pretty simple.
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.
Tox is an encrypted peer-to-peer messaging system and so should work without Freedombone. It uses a system of nodes which act as a sort of directory service allowing users to find and connect to each other. The Tox node ID on the Freedombone can be found within the README within your home directory. If you have other users connect to your node then you will be able to continue chatting even when no other nodes are available.
Click on "add new" to add a new server and enter the default domain name for the Freedombone, your username (which can be anything) and the VoIP server password which can be found in the README file on the Freedombone. Accept the self-signed SSL certificate. You are now ready to chat.
/Note: if you don't know the default domain name and you did a full installation then it will be the same as the wiki domain name./
*** Using with Android
Install [[https://f-droid.org/][F-Droid]]
Search for and install Plumble.
Press the plus button to add a Mumble server.
Enter a label (which can be any name you choose for the server), the default domain name of the Freedombone, your username (which can also be anything) and the VoIP server password which can be found in the README file on the Freedombone.
Selecting the server by pressing on it then connects you to the server so that you can chat with other connected users.
/Note: if you don't know the default domain name and you did a full installation then it will be the same as the wiki domain name./
Freedombone also supports SIP phones The username and domain is the same as for your email address, and the SIP password and extension number will appear within the README file in your home directory. Various SIP client options are available, such as CSipSimple on Android and Jitsi on desktop or laptop machines. Ideally use clients which support ZRTP, which will provide the best level of security.[fn:1]
