<h2 id="org8f26a4a">Readme</h2>
<div class="outline-text-2" id="text-org8f26a4a">
<p>
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:
</p>
<div class="org-src-container">
<pre class="src src-bash">ssh username@domainname -p 2222
emacs ~/README
</pre>
</div>
<p>
You should transfer any passwords to a password manager such as <a href="https://www.keepassx.org/">KeepassX</a> and then delete them from the README file. To save the file after removing passwords use <b>CTRL-x CTRL-s</b>.
</p>
<p>
To exit you can either just close the terminal or use <b>CTRL-x CTRL-c</b> followed by the <b>exit</b> command.

<h2 id="orgb27cb32">Improving ssh security</h2>
<div class="outline-text-2" id="text-orgb27cb32">
<p>
To improve ssh security you can generate an ssh key pair on your system and then upload the public key to the Freedombone.
</p>
<p>
On your local machine:
</p>
<div class="org-src-container">
<pre class="src src-bash">ssh-keygen
</pre>
</div>
<p>
For extra security you may also want to add a passphrase to the ssh private key. You can show the generated public key with:
</p>
<div class="org-src-container">
<pre class="src src-bash">cat ~/.ssh/id_rsa.pub
</pre>
</div>
<p>
Log into your system and open the control panel.
</p>
<div class="org-src-container">
<pre class="src src-bash">ssh username@domain -p 2222
</pre>
</div>
<p>
Select <i>Administrator controls</i> then <i>Manage Users</i> then <i>Change user ssh public key</i>. Copy and paste the public key here, then exit.
</p>
<p>
It's a good idea to also copy the contents of <b>~/.ssh/id_rsa</b> and <b>~/.ssh/id_rsa.pub</b> to you password manager, together with the private key password if you created one.
</p>
<p>
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.
</p>
<p>
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 <i>Security Settings</i> 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.
</p>
</div>

<div id="outline-container-org28dd407" class="outline-2">
<h2 id="org28dd407">Administrating the system via an onion address (Tor)</h2>
<div class="outline-text-2" id="text-org28dd407">
<p>
You can also access your system via the Tor system using an onion address. To find out what the onion address for ssh access is you can do the following:
</p>
<div class="org-src-container">
<pre class="src src-bash">ssh username@freedombone.local -p 2222
</pre>
</div>
<p>
Select <i>Administrator controls</i> then select "About this system" and look for the onion address for ssh. You can then close the terminal and open another, then do the following on your local system:
</p>
<div class="org-src-container">
<pre class="src src-bash">freedombone-client
</pre>
</div>
<p>
This will set up your ssh environment to be able to handle onion addresses. In addition if you use monkeysphere then you can do:
</p>
<div class="org-src-container">
<pre class="src src-bash">freedombone-client --ms yes
</pre>
</div>
<p>
Then you can test ssh with:
</p>
<div class="org-src-container">
<pre class="src src-bash">ssh username@address.onion -p 2222
</pre>
</div>
<p>
Subsequently even if dynamic DNS isn't working you may still be able to administer your system. Using the onion address also gives you some degree of protection against corporate or government metadata analysis, since it becomes more difficult to passively detect which systems are communicating.

<h3 id="org0b87a9e">With the DLNA service</h3>
<div class="outline-text-3" id="text-org0b87a9e">
<p>
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 "<i>Music</i>" on a USB thumb drive and then insert it into from socket on the Beaglebone.
</p>
<p>
ssh into the system with:
</p>
<div class="org-src-container">
<pre class="src src-bash">ssh myusername@mydomain.com -p 2222
</pre>
</div>
<p>
Then mount the USB drive with:
</p>
<div class="org-src-container">
<pre class="src src-bash">su
attach-music
</pre>
</div>
<p>
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 <b>exit</b> a couple of times.
</p>
<p>
If you have an Android device then go to F-Droid (if you don't already have it installed then it can be <a href="https://f-droid.org/">downloaded here</a>) and search for <b>ControlDLNA</b>. 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.
</p>
<p>
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.

<p>
GNU Social has a clutter-free mobile user interface which can be accessed via a Tor compatible browser (make sure to add a NoScript exception). Unlike similar proprietary sites there are no bribed posts.

<p>
One important point about GNU Social is that although direct messages (DMs) are treated as being private their security is quite poor. If you want real communications privacy then use other systems such as XMPP+OMEMO/OTR, Tox or email with GPG. GNU Social is primarily about <i>fully public communications</i>.

<h2 id="org0e52735">Sharing things</h2>
<div class="outline-text-2" id="text-org0e52735">
<p>
If you have the GNU Social microblogging system installed then it's also possible to share things or services between groups or with particular users. This can be useful for sharing items within a family, club or in a local sharing economy. Sharing things freely, without money, reveals the social basis at the root of all economics which money normally conceals or obscures.

<p>
Click on "<i>share</i>" or "<i>my catalog</i>" and this will switch to a screen which allows you to enter details for things to be shared or wanted.

<p>
Both Hubzilla and GNU Social try to obtain certificates automatically at the time of installation via Let's Encrypt. This will likely mean that in order for this to work you'll need to have obtained at least one "official" domain via a domain selling service, since Let's Encrypt mostly doesn't seem to work with free subdomains from sites such as freeDNS.

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.

<h4 id="org4d790e3">Irssi</h4>
<div class="outline-text-4" id="text-org4d790e3">
<p>
The easiest way to use irssi is to connect to your system, like this:
</p>
<div class="org-src-container">
<pre class="src src-bash">ssh myusername@mydomain -p 2222
</pre>
</div>
<p>
Then select <b>IRC</b> from the menu. However, other than via this method using ssh, irssi isn't a very good IRC client because it doesn't have the capability to onion route messages, and therefore leaks metadata. For the best security when using your IRC server, use HexChat, Emacs ERC or another client which supports socks5 proxying.

<h4 id="orgd0403ac">HexChat</h4>
<div class="outline-text-4" id="text-orgd0403ac">
<p>
HexChat (formerly XChat) is compatible with proxying via Tor and so provides the best security when connecting to your IRC server. It will allow you to connect to your IRC server's onion address.
</p>
<p>
First install HexChat and set up its configuration file. This can be done on your local machine with:
</p>
<div class="org-src-container">
<pre class="src src-bash">freedombone-client --setup hexchat
</pre>
</div>
<p>
Now look up the onion address for your IRC server
</p>
<div class="org-src-container">
<pre class="src src-bash">ssh username@mydomainname -p 2222
</pre>
</div>
<p>
Select Administrator options, then <b>About this system</b> and make a note of the onion address for IRC. Also select the <b>IRC Menu</b> and take a note of the login password.
</p>
<p>
Run HexChat.
</p>
<p>
Within the network list click, <b>Add</b> and enter your domain name then click <b>Edit</b>.
</p>
<p>
Select the entry within the servers box, then enter <b>ircaddress.onion/6697</b> or <b>mydomainname/6697</b> and press <b>Enter</b>.
</p>
<p>
Uncheck <b>use global user information</b>.
</p>
<p>
Enter first and second nicknames and check <b>connect to this network on startup</b>.
</p>
<p>
If you are using the ordinary domain name (clearnet/ICANN) then make sure that <b>Use SSL</b> is checked.
</p>
<div class="figure">
<p><img src="images/hexchat_setup_clearnet.jpg" alt="hexchat_setup_clearnet.jpg" />

<h4 id="org9c40bca">Using with Gajim</h4>
<div class="outline-text-4" id="text-org9c40bca">
<p>
In mid 2016 <a href="https://gajim.org/">Gajim</a> became the first desktop XMPP client to support the <a href="https://en.wikipedia.org/wiki/OMEMO">OMEMO end-to-end security standard</a>, which is superior to the more traditional <a href="https://en.wikipedia.org/wiki/Off-the-Record_Messaging">OTR</a> since it also includes multi-user chat and the ratcheting mechanism pioneered by Open Whisper Systems. To install it:
</p>
<div class="org-src-container">
<pre class="src src-bash">su -c <span class="org-string">'echo "deb ftp://ftp.gajim.org/debian unstable main" &gt; /etc/apt/sources.list.d/gajim.list'</span>
sudo apt-get update
sudo apt-get -y install gajim-dev-keyring
sudo apt-get -y install git tor python-dev python-pip gajim-nightly
mkdir ~/.local/share/gajim/plugins -p
<span class="org-builtin">cd</span> ~/.local/share/gajim/plugins
git clone https://github.com/omemo/gajim-omemo
sudo pip install <span class="org-variable-name">protobuf</span>==2.6.1, python-axolotl==0.1.35
</pre>
</div>
<p>
Open Gajim and enter your XMPP address and password.
</p>
<p>
Go to <b>Edit/Preferences</b> and select the <b>Advanced</b> tab. Under <b>Global Proxy</b> select <b>Tor</b> and the <b>Close</b> button. Then select <b>Edit/Plugins</b> and make sure that OMEMO is active (ticked), then select the <b>Close</b> button.
</p>
<p>
When you start a conversation make sure that the OMEMO box is ticked. You can also click on the keys button and trust various fingerprints. Both sides will need to do that before an encrypted chat can start.
</p>
<p>
If you wish to make backups of the OMEMO keys then they can be found within:
</p>
<div class="org-src-container">
<pre class="src src-bash">~/.local/share/gajim
</pre>
</div>
<p>
If you wish to use OpenPGP to encrypt your messages then go to <b>Edit/Accounts</b>, select your account and then the <b>Personal Information</b> tab. You can then choose your GPG key. When initiating a chat you can select the <b>Advanced</b> button and then select <b>Toggle OpenPGP Encryption</b>. OpenPGP is not as secure as OMEMO, but does allow you to use XMPP in a similar style to email in that the recipient of the message does not necessarily need to be online at the same time that you send it.

<div class="outline-text-4" id="text-orge5eb75d">
<p>
The <a href="https://profanity.im">Profanity</a> shell based user interface and is perhaps the simplest way to use XMPP from a laptop. It's also a good way to ensure that your OTR keys are the same even when logging in from different laptops or devices, and it also means that if those devices later become compomised then there are no locally stored OTR keys to be found.
</p>
<div class="org-src-container">
<pre class="src src-bash">ssh username@domain -p 2222
</pre>
</div>
<p>
Then select XMPP. Generate an <a href="https://en.wikipedia.org/wiki/Off-the-Record_Messaging">OTR</a> key with:
</p>
<div class="org-src-container">
<pre class="src src-bash">/otr gen
</pre>
</div>
<p>
Then to start a conversation using OTR:
</p>
<div class="org-src-container">
<pre class="src src-bash">/otr start otherusername@otheruserdomain
</pre>
</div>
<p>
or if you're already in an insecure chat with someone just use:
</p>
<div class="org-src-container">
<pre class="src src-bash">/otr start
</pre>
</div>
<p>
Set a security question and answer:
</p>
<div class="org-src-container">
<pre class="src src-bash">/otr question <span class="org-string">"What is the name of your best friends rabbit?"</span> fiffi
</pre>
</div>
<p>
On the other side the user can enter:
</p>
<div class="org-src-container">
<pre class="src src-bash">/otr answer fiffi
</pre>
</div>
<p>
For the most paranoid you can also obtain your fingerprint:
</p>
<div class="org-src-container">
<pre class="src src-bash">/otr myfp
</pre>
</div>
<p>
and quote that. If they quote theirs back you can check it with:
</p>
<div class="org-src-container">
<pre class="src src-bash">/otr theirfp
</pre>
</div>
<p>
If the fingerprints match then you can be pretty confident that unless you have been socially engineered via the question and answer you probably are talking to who you think you are, and that it will be difficult for mass surveillance systems to know the content of the conversation. For more details see <a href="https://www.profanity.im/otr.html">this guide</a>
</p>
<p>
When accessed via the user control panel the client is automatically routed through Tor and so if you are also using OTR then this provides protection for both message content and metadata.

<h4 id="orga01801d">Using with Jitsi</h4>
<div class="outline-text-4" id="text-orga01801d">
<p>
Jitsi is the recommended communications client for desktop or laptop systems, since it includes the <i>off the record</i> (OTR) feature which provides some additional security beyond the usual SSL certificates.
</p>
<p>
Jitsi can be downloaded from <a href="https://jitsi.org">https://jitsi.org</a>
</p>
<p>
On your desktop/laptop open Jitsi and select <b>Options</b> from the <b>Tools</b> menu.
</p>
<p>
Click <b>Add</b> to add a new user, then enter the Jabber ID which you previously specified with <i>prosodyctl</i> 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).
</p>
<p>
From the <b>File</b> 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.
</p>
<p>
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 <b>View Certificate</b> and enable the checkbox to trust the certificate, then select <b>Continue Anyway</b>. Once you've done this then the certificate warning will not appear again unless you reinstall Jitsi or use a different computer.
</p>
<p>
You can also <a href="https://www.youtube.com/watch?v=vgx7VSrDGjk">see this video</a> as an example of using OTR.

The default XMPP client in Ubuntu is Empathy. Using Empathy isn't as secure as using Jitsi, since it doesn't include the <i>off the record</i> feature, but since it's the default it's what many users will have easy access to.
</p>
<p>
Open <b>System Settings</b> and select <b>Online Accounts</b>, <b>Add account</b> and then <b>Jabber</b>.

<p>
Click on <b>Advanced</b> and make sure that <b>Encryption required</b> and <b>Ignore SSL certificate errors</b> are checked.

<a href="https://jitsi.org/Documentation/ZrtpFAQ">ZRTP</a> appears to be the current best standard to end-to-end encrypted voice calls, combining good security with simplicity of use. 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.

The RSS reader is accessible only via an onion address. This provides a reasonable degree of reading privacy, making it difficult for passive adversaries such as governments, corporations or criminals to create lists of sites which you are subscribed to.
</p>
<p>
To set up the system open <a href="http://rss_reader_onion_address">http://rss_reader_onion_address</a> and log in with username <b>admin</b> and the password obtained either at the beginning of the install or from the README file in your home directory. You can then select the <b>Actions</b> menu and begin adding your feeds.

<div class="outline-text-3" id="text-org8125a0f">
<p>
To access the RSS reader from a mobile device you can install a Tor compatible browser such as OrFox. It will try to automatically change to the mobile version of the user interface. Remember to add the site to the NoScript whitelist, and you may also need to turn HTTPS Everywhere off.
</p>
<blockquote>
<p>
A note for the paranoid is that on mobile devices you get redirected to a different onion address which is specially set up for the mobile interface, so don't be alarmed that it looks like your connection is being hijacked.

<p>
If you are an Emacs user then you can also read your RSS feeds via the <a href="https://github.com/dk87/avandu">Avandu</a> mode.
</p>
<p>
Add the following to your configuration, changing the address and password as appropriate.
</p>
<div class="org-src-container">
<pre class="src src-emacs-lisp">(<span class="org-keyword">setq</span> avandu-tt-rss-api-url <span class="org-string">"http://rss_reader_onion_address/api/"</span>

avandu-password <span class="org-string">"mypassword"</span>)
</pre>
</div>
<p>
If you don't already have Emacs set up to route through Tor then also add the following:
</p>
<div class="org-src-container">
<pre class="src src-emacs-lisp">(<span class="org-keyword">setq</span> socks-noproxy '(<span class="org-string">"localhost"</span>))

<div class="outline-text-2" id="text-orgd680579">
<p>
Github is ok, but it's proprietary and funded by venture capital. If you been around on the internet for long enough then you know how this story eventually works itself out - i.e. badly for the users. It's really only a question of time. If you're a software developer or do things which involve the Git version control system then it's a good idea to become accustomed to hosting your own repositories, before the inevitable Github shitstorm happens.
</p>
<p>
A Git hosting system called <a href="https://gogs.io">Gogs</a> can optionally be installed. This is very similar to Github in appearance and use. It's lightweight and so well suited for use on low power ARM servers.
</p>
<p>
Navigate to your git site and click the <b>Register</b> button. The first user registered on the system becomes the administrator. Once you've done that then it's a good idea to disable further registrations. Currently that's a little complicated, but you can do it as follows:
</p>
<div class="org-src-container">
<pre class="src src-bash">sudo username@domainname -p 2222
</pre>
</div>
<p>
Select <b>Exit to the comand line</b>.
</p>
<div class="org-src-container">
<pre class="src src-bash">sudo su
sed -i <span class="org-string">"s|DISABLE_REGISTRATION =.*|DISABLE_REGISTRATION = true|g"</span> /home/gogs/custom/conf/app.ini
sed -i <span class="org-string">"s|SHOW_REGISTRATION_BUTTON =.*|SHOW_REGISTRATION_BUTTON = false|g"</span> /home/gogs/custom/conf/app.ini
systemctl restart gogs
<span class="org-keyword">exit</span>; <span class="org-keyword">exit</span>

This will stop any spam accounts being created by random strangers or bots. You might want to mirror existing repos, and at any time a mirror can be converted into the main repo.

<h2 id="org4347af5">Blocking Ads</h2>
<div class="outline-text-2" id="text-org4347af5">
<p>
Everyone except for advertisers hates adverts. Not only are they annoying, but they can consume a lot of bandwidth, be a privacy problem in terms of allowing companies to track your browsing habits and also any badly written scripts they contain may introduce exploitable security holes. Also if you're poor then adverts often make you want things that you can't have.
</p>
<p>
You can block ads for any devices connected to your local network by installing the <b>pihole</b> app from <b>Add/Remove Apps</b> on the administrator control panel. This may help to improve overall performance of your devices by not wasting time downloading unwanted images or scripts.
</p>
<p>
Also don't expect perfection. Though many ads may be blocked by this system some will still get through. It's a constant cat and mouse game between advertisers and blockers.

<div id="outline-container-orgf720b80" class="outline-3">
<h3 id="orgf720b80">Set a static IP address</h3>
<div class="outline-text-3" id="text-orgf720b80">
<p>
Ensure that your system has a static local IP address (typically 192.168..) using the option on the control panel. You will also need to know the IP address of your internet router, which is usually <b>192.168.1.1</b> or <b>192.168.1.254</b>.
</p>
<p>
When that's done select <b>About this system</b> from the control panel and see the IPv4 address. You can use this as a DNS address in two ways:
</p>
</div>
</div>
<div id="outline-container-org11b92f7" class="outline-3">
<h3 id="org11b92f7">On each client system within your local network</h3>
<div class="outline-text-3" id="text-org11b92f7">
<div class="org-src-container">
<pre class="src src-bash">sudo chattr -i /etc/resolv.conf
sudo nano /etc/resolv.conf
</pre>
</div>
<p>
Comment out any existing entries with a # character and add:
</p>
<div class="org-src-container">
<pre class="src src-bash">nameserver [IPv4 address from the About screen]
</pre>
</div>
<p>
Normally <i>resolv.conf</i> will be overwritten every time your reboot, but you can prevent this with:
</p>
<div class="org-src-container">
<pre class="src src-bash">sudo chattr +i /etc/resolv.conf
</pre>
</div>
</div>
</div>
<div id="outline-container-org8fc2ddf" class="outline-3">
<h3 id="org8fc2ddf">On your internet router</h3>
<div class="outline-text-3" id="text-org8fc2ddf">
<p>
If you can access the settings on your local internet router then this is the simplest way to provide ad blocking for all devices which connect to it. Unfortunately some router models don't let you edit the DNS settings and if that's the case you might want to consider getting a different router.
</p>
<p>
Edit the DNS settings and add the IPv4 address which you got from the control panel About screen. Exactly how you do this will just depend upon your particular router model. You may also need to set the same address twice, because two addresses are conventional.

On a router running LibreCMC from the <b>Network</b> menu select <b>DHCP and DNS</b>.

Any devices which connect to your router will now have ad blocking.

<p>
You can configure the block lists which the system uses by going to the <b>administrator control panel</b>, selecting <b>App Settings</b> then choosing <b>pihole</b>. You can also add any extra domain names to the whitelist if they're being wrongly blocked or to the blacklist if they're not blocked by the current lists.
