 * Why can't I access my .onion site with a Tor browser?
132 132 
 Probably you need to add the site to the NoScript whitelist. Typically click/press on the noscript icon (or select from the menu on mobile) then select /whitelist/ and add the site URL. You may also need to disable HTTPS Everywhere when using onion addresses, which don't use https.

+Another factor to be aware of is that it can take a while for the onion address to become available within the Tor network. In tests the amount of time between creating a site and being able to access it's onion address seems to vary between a minute or two and half an hour. So don't be too impatient if the address doesn't appear to resolve straight away.

 * What is the best hardware to run this system on?
134 136 
 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 [[https://en.wikipedia.org/wiki/Uninterruptible_power_supply][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.

 Yes. The minimum requirements are to have some hardware that you can install Debian onto and also that you have administrator access to your internet router so that you can forward ports to the system which has Freedombone installed.

 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:

 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.

 Before you run screaming for the hills based upon whatever scare story you may have just read in the mainstream media there are a few things worthy of consideration. Tor is installed by default on Freedombone, <i>but not as a relay or exit node</i>. It's only used to provide onion addresses so that this gives you or the viewers of your sites some choice about how they access the information. It also allows you to subscribe to and read RSS feeds privately.

 Github is paradoxically a centralized, closed and proprietary system which happens to mostly host free and open source projects. Up until now it has been relatively benign, but at some point in the name of "growth" it will likely start becoming more evil, or just become like SourceForge - which was also once much loved by FOSS developers, but turned into a den of malvertizing.

 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 <a href="https://en.wikipedia.org/wiki/Uninterruptible_power_supply">UPS capability</a> 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.

 On mobile there are various options. The apps which are likely to be most secure are ones which have end-to-end encryption enabled by default and which can also be onion routed via Orbot. End-to-end encryption secures the content of the message and onion routing obscures the metadata, making it hard for a passive adversary to know who is communicating with who.

 Almost everywhere on the web you will read that self-signed certificates are worthless. They bring up <i>scary-scary looking</i> browser warnings and gurus will advise you not to use them. Self-signed certificates are quite useful though. What the scary warnings mean - and it would be good if they explained this more clearly - is that you have an encrypted connection established but there is <i>no certainty about who that connection is with</i>. They probably will protect the content of your communications from passive bulk interception - such as the tapping of under-sea cables.

 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.
