Why Freedombone and not FreedomBox?

When the project began in late 2013 the FreedomBox project seemed to be going nowhere, and was only designed to work with the DreamPlug hardware. There was some new hardware out - the Beaglebone Black - which could run Debian and was also a free hardware design so seemed more appropriate. Hence the name "Freedombone", being like FreedomBox but on a Beaglebone. There are some similarities and differences between the two projects:

Why not support building images for Raspberry Pi?

+

The FreedomBox project supports Raspberry Pi builds, and the image build system for Freedombone is based on the same system. However, although the Raspberry Pi can run a version of Debian it requires a closed proprietary blob in order to boot the hardware. Who knows what that blob might contain or what exploits it could facilitate. From an adversarial point of view if you were trying to deliver "bulk equipment interference" then it doesn't get any better than piggybacking on something which has control of the boot process, and hence all subsequently run processes.

You could if you manually edited the relevant nginx configuration files and installed some dynamic DNS system yourself. If you already have sysadmin knowledge then that's probably not too hard.

It was originally designed to run on the Beaglebone Black, but that should be regarded as the most minimal system, because it's single core and has by today's standards a small amount of memory. Obviously the more powerful the hardware is the faster things like web pages (blog, social networking, etc) will be served but the more electricity such a system will require if you're running it 24/7. A good compromise between performance and energy consumption is something like an old netbook. The battery of an old netbook or laptop even gives you UPS capability to keep the system going during brief power outages or cable re-arrangements, and that means using full disk encryption on the server also becomes more practical.

How do I get a "real" SSL/TLS/HTTPS certificate?

Normally certificates will be automatically renewed once per month, so you don't need to be concerned about it. If anything goes wrong with the automatic renewal then you should receive a warning email.

Most likely it's because Let's Encrypt doesn't support your particular domain or subdomain. Currently free subdomains tend not to work. You'll need to buy a domain name, link it to your dynamic DNS account and then do:

Why not use the services of $company instead? They took the Seppuku pledge

-That pledge is utterly worthless. Years ago people trusted Google in the same sort of way, because they promised not be be evil and because a lot of the engineers working for them seemed like honest types who were "on our side". Post-nymwars and post-PRISM we know exactly how much Google cared about the privacy and security of its users. But Google is only one particular example. In general don't trust pledges made by companies, even if the people running them seem really sincere. +That pledge is utterly worthless.

Why does my email keep getting rejected as spam by Gmail/etc?

Welcome to the world of email. Email is really the archetypal decentralized service, developed during the early days of the internet. In principle anyone can run an email server, and that's exactly what you're doing with Freedombone. Email is very useful, but it has a big problem, and that's that the protocols are totally insecure. That made it easy for spammers to do their thing, and in response highly elaborate spam filtering and blocking systems were developed. Chances are that your emails are being blocked in this way. Sometimes the blocking is so indisciminate that entire countries are excluded. What can you do about it? Unless you control the block list at the receiving end you may not be able to do much unless you can find an email proxy server which is trusted by the receiving server.

Tor is censored/blocked in my area. What can I do?

If you can find some details for an obfs4 Tor bridge (its IP address, port number and key or nickname) then you can set up the system to use it to connect to the Tor network. Unlike relay nodes the IP addresses for bridges are not public information and so can't be easily known and added to block lists by authoritarian regimes or over-zealous ISPs.

I want to block a particular domain from getting its content into my social network sites

If you're being pestered by some domain which contains bad/illegal/harrassing content or irritating users you can block domains at the firewall level. Go to the administrator control panel and select domain blocking. You can then block, unblock and view the list of blocked domains.
