 * I don't have a static IP address. Can I still install this system?
 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.

 * 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.

 * Can I add more users to the system?
 Yes. Freedombone can support a small number of users, for a "/friends and family/" type of home installation. This gives them access to an email account, XMPP, SIP phone and the blog (depending on whether the variant which you installed includes those).
 
-#+BEGIN_SRC bash

 Select /Administrator controls/ then /Manage Users/ and then /Add a user/. You will be prompted for a username and you can also optionally provide their ssh public key.
 
 Something to consider when having more than a single user on the system is the security situation. The original administrator user will have access to all of the data for other users (including their encryption keys), so if you do add extra users they need to have *complete trust* in the administrator.
 
 Another point is that Freedombone installations are not intended to support many users (maybe ten at most). Large numbers of users may make the system unstable, and the more users you have on one system the more it becomes a single point of failure and also perhaps a honeypot from the standpoint of adversaries. Think of what happened with Lavabit and the moral dilemma which an administrator can be faced with (comply with threats and betray the trust of your users or don't comply and suffer other consequences). Ideally, you never want to put yourself into a situation where you can be forced to betray others.
+* What is the most secure chat app to use on mobile?
+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.
+
+The current safest way to chat is to use [[https://conversations.im][Conversations]] together with [[https://guardianproject.info/apps/orbot/][Orbot]] - both of which can be installed from [[https://f-droid.org/][F-droid]]. You may need to enable the [[https://guardianproject.info/][Guardian Project]] repository within F-droid in order to be able to install Orbot. Within the settings of the Conversations app you can set it to route via Tor, and also you can use the XMPP service of your Freedombone server. That way all of the software infrastructure is controlled by you or your community.
+
+There are many other fashionable chat apps with end-to-end security, but often they are closed source or can't be onion routed. For example, this means that although the often recommended Signal app may have state of the art security for the content of each message, in all likelihood Google and whichever agencies they are friendly with will be able to obtain a /complete social graph/ of all Signal users, revealing who chats with who. It's also important to remember that closed source chat apps should be assumed to be untrustworthy, since their security cannot be independently audited.

 Even when using Freedombone metadata analysis by third parties is still possible. This can be mitigated by accessing your blog, or other web services, via their /onion addresses/, rather than via more conventional domain names. In that case your ISP and any government which they might be compelled to report back to will know when your system is being accessed, but not necessarily /which/ services are being accessed /or by whom/. So for instance using a Tor browser and the onion address people may be able to safely read your blog or wiki and be reasonably confident that metadata isn't being gathered about what they read (or more concisely the metadata which can be gathered by a third party may just not be very useful or personally identifiable). On the other hand if you access the system via conventional domain names and dynamic DNS then it's safe to assume that metadata can and will be collected by third parties.

 For now a self-signed certificate will probably in most cases protect your communications from "bulk" passive surveillance. Once you've got past the scary browser warning and accepted the certificate under most conditions (except when starting up the Tor browser) you should not repeatedly see that warning. If you do then someone may be trying to meddle with your connection to the server. You can also take a note of the fingerprint of the certificate and verify that if you are especially concerned. If the fingerprint remains the same then you're probably ok.

 * 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.
 
 Often ISPs will run their own SMTP mail server which you can use for proxying, typically called /mail.ISPdomain/. On the administrator control panel there is an option to set the details for outgoing email from the Mutt client.
 
-#+BEGIN_SRC bash
+#+begin_src bash
 ssh username@mydomainname -p 2222
-#+END_SRC
+#+end_src
 
 Select /Administrator controls/ then *Outgoing Email Proxy* and enter the details for your ISP SMTP server.

 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.

+<div class="outline-text-2" id="text-orgef8453">
+<p>
+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.
+</p>
+
+<p>
+The current safest way to chat is to use <a href="https://conversations.im/">Conversations</a> together with <a href="https://guardianproject.info/apps/orbot/">Orbot</a> - both of which can be installed from <a href="https://f-droid.org/">F-droid</a>. You may need to enable the <a href="https://guardianproject.info/">Guardian Project</a> repository within F-droid in order to be able to install Orbot. Within the settings of the Conversations app you can set it to route via Tor, and also you can use the XMPP service of your Freedombone server. That way all of the software infrastructure is controlled by you or your community.
+</p>
+
+<p>
+There are many other fashionable chat apps with end-to-end security, but often they are closed source or can't be onion routed. For example, this means that although the often recommended Signal app may have state of the art security for the content of each message, in all likelihood Google and whichever agencies they are friendly with will be able to obtain a <i>complete social graph</i> of all Signal users, revealing who chats with who. It's also important to remember that closed source chat apps should be assumed to be untrustworthy, since their security cannot be independently audited.

 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.

 Use a Linux based phone operating system. Typically this will mean Android, but could also mean Cyanogenmod or Replicant. Cyanogen is the most preferable, because you can usually get an up to date image with a recent kernel which will give you better security against exploits. If you're buying a phone then look for a model which is supported by Cyanogenmod. Replicant is the most free (as in freedom) but only runs on a small number of phone models. If you have a phone which runs a full GNU/Linux system then that's fantastic, and you can probably use it in much the same way as a desktop system and the rest of the advice on this page won't apply. If you don't have a phone capable of running a Linux based operating system then consider selling, giving away or bartering your existing one.

 So maybe you're running Android and the phone came with some apps already installed. Almost certainly they'll be proprietary. Go to Settings/Apps and then uninstall or deactivate any apps which you really don't need. Mostly preinstalled apps are intended to send your data to companies who will then sell it to advertisers or governments under the business model of <i>surveillance capital</i>. It's not a good idea to get caught up in that, and to avoid becoming addicted to apps which are surveilling you without consent or installing spyware in the background without your knowledge.

If your phone is subsequently stolen then even if an adversary can get past the lock screen <i>there are no emails stored on the phone</i>.

 <a href="https://syncthing.net/">Syncthing</a> provides a similar capability to proprietary systems such as <a href="http://www.drop-dropbox.com/">Dropbox</a>, and also is well suited for use with low power single board computers. You can have one or more directories which are synchronized across your various laptops/desktops/devices, and this makes it hard for you to ever lose important files. The manner in which the synchronization is done is pretty secure, such that it would be difficult for passive adversaries (mass surveillance, "<i>men in the middle</i>", etc) to know what files you're sharing. Of course, you don't necessarily need to be running a server in order to use Syncthing, but if you do have a server which is always running then there's always at least one place to synchronize your files to or from.

When the initial cryptographic negotiation between phones is done at the start of a call a short authentication string (SAS) is calculated and displayed at both ends. To check that there isn't anyone intercepting the call and acting as a <i>man in the middle</i> - as <a href="https://en.wikipedia.org/wiki/Stingray_phone_tracker">stingray type devices</a> try to do - the short authentication string can be read out and verbally confirmed between the callers.

 The way that RSS reading is set up on Freedombone gives you strong reading privacy. Not only is there onion routing between you and the server but also between the server and the source of the RSS feed. The only down side is that many RSS feeds are still http only, and so could be vulnerable to injection attacks, but it's expected that more of this will go to https in the foreseeable future due to a combination of growing recognition of security issues and systems like Let's Encrypt which make obtaining certificates much easier.
