+
+A Virtual Private Network (VPN) allows you to move your internet traffic to a different machine in a different geographical location by creating a private cryptographically protected route to that location. The usual use cases are to get around local censorship of the internet such as when you see the message "/this content is not available in your area/" when trying to play a video. Maybe you're on holiday and your hotel or workplace internet connection is censored. Using a VPN you can connect to your home server and then use the internet normally.
+
+Using a Tor browser is another way to get around censorship, but there might be occasions where you don't want to use a Tor browser or where Tor relays and bridges are blocked or where you want to run internet apps which aren't within a browser.
+
+On Freedombone the VPN is wrapped within a TLS layer of encryption, making it difficult for any deep packet inspection systems to know whether you are using a VPN or not. Since there is lots of TLS traffic on the internet your connection looks like any other TLS connection to a server, and this may help to avoid being censored. It's probably not possible for your local ISP to block TLS traffic without immediately generating a lot of irate customers, and stopping any kind of commercial activity.
+
+* Installation
+
+ssh into the system with:
+
+#+BEGIN_SRC bash
+ssh myusername@mydomainname -p 2222
+#+END_SRC
+
+Select *Administrator controls* then *Add/Remove apps* then *vpn*. Choose the port which you want the VPN to operate on and then the install will continue.
+
+Only use ports 443 or 80 for VPN as an /absolute last resort/, since doing so will prevent other web based apps from running on your server.
+
+* Usage
+
+When the installation is complete you can download your VPN keys and configuration files onto your local machine.
+
+#+begin_src bash
+scp -P 2222 myusername@mydomainname:/home/myusername/client.ovpn .
+scp -P 2222 myusername@mydomainname:/home/myusername/stunnel* .
+#+end_src
+
+You will need to ensure that the /openvpn/ and /stunnel/ packages are installed. On an Arch based system:
+
+#+begin_src bash
+sudp pacman -S openvpn stunnel4
+#+end_src
+
+Or on a Debian based system:
+
+#+begin_src bash
+sudo apt-get install openvpn stunnel4
+#+end_src
+
+Now you can connect to your VPN with:
+
+#+begin_src bash
+sudo stunnel stunnel-client.conf
+sudo openvpn client.ovpn
+#+end_src
+
+You should see a series of messages with "/Initialization Sequence Completed/" showing at the end. Leave the terminal open and perhaps minimize it to remain connected to the VPN. To leave the VPN close the terminal window.
+
+* Changing port number
+
+Avoiding censorship can be a cat and mouse game, and so if the port you're using for VPN gets blocked then you may want to change it.
+
+#+BEGIN_SRC bash
+ssh myusername@mydomainname -p 2222
+#+END_SRC
+
+Select *Administrator controls* then *App Settings* then *vpn*. Choose *Change TLS port* and enter a new port value. You can then either manually change the port within your VPN configuration files, or download them again as described in the [[Usage]] section above.
+
+* Generating new keys
+
+It's possible that your VPN keys might get lost or compromised on your local machine. If that happens you can generate new ones from the *Administrator controls* by going to *App Settings* then *vpn* then choosing *Regenerate keys for a user* and downloading the new keys as described in the [[Usage]] section above.

 * Vim
 If you use the Mutt client to read your email then this will set it up to use vim for composing new mail.
 
+* Virtual Private Network (VPN)
+Set up a VPN on your server so that you can bypass local internet censorship.

 * XMPP
 Chat server which can be used together with client such as Gajim or Conversations to provide end-to-end content security and also onion routed metadata security. Includes advanced features such as /client state notification/ to save battery power on your mobile devices, support for seamless roaming between networks and /message carbons/ so that you can receive the same messages while being simultaneously logged in to your account on more than one device.

+
+<blockquote>
+<p>
+"<i>The Net interprets censorship as damage and routes around it.</i>" &#x2013; John Gilmore
+</p>
+</blockquote>
+
+<p>
+A Virtual Private Network (VPN) allows you to move your internet traffic to a different machine in a different geographical location by creating a private cryptographically protected route to that location. The usual use cases are to get around local censorship of the internet such as when you see the message "<i>this content is not available in your area</i>" when trying to play a video. Maybe you're on holiday and your hotel or workplace internet connection is censored. Using a VPN you can connect to your home server and then use the internet normally.
+</p>
+
+<p>
+Using a Tor browser is another way to get around censorship, but there might be occasions where you don't want to use a Tor browser or where Tor relays and bridges are blocked or where you want to run internet apps which aren't within a browser.
+</p>
+
+<p>
+On Freedombone the VPN is wrapped within a TLS layer of encryption, making it difficult for any deep packet inspection systems to know whether you are using a VPN or not. Since there is lots of TLS traffic on the internet your connection looks like any other TLS connection to a server, and this may help to avoid being censored. It's probably not possible for your local ISP to block TLS traffic without immediately generating a lot of irate customers, and stopping any kind of commercial activity.

+<div id="outline-container-org778c839" class="outline-2">
+<h2 id="org778c839">Installation</h2>
+<div class="outline-text-2" id="text-org778c839">
+<p>
+ssh into the system with:
+</p>
+
+<div class="org-src-container">
+<pre class="src src-bash">ssh myusername@mydomainname -p 2222
+</pre>
+</div>
+
+<p>
+Select <b>Administrator controls</b> then <b>Add/Remove apps</b> then <b>vpn</b>. Choose the port which you want the VPN to operate on and then the install will continue.
+</p>
+
+<p>
+Only use ports 443 or 80 for VPN as an <i>absolute last resort</i>, since doing so will prevent other web based apps from running on your server.
+</p>
+</div>
+</div>
+
+<div id="outline-container-org2cfcc49" class="outline-2">
+<h2 id="org2cfcc49">Usage</h2>
+<div class="outline-text-2" id="text-org2cfcc49">
+<p>
+When the installation is complete you can download your VPN keys and configuration files onto your local machine.
+</p>
+
+<div class="org-src-container">
+<pre class="src src-bash">scp -P 2222 myusername@mydomainname:/home/myusername/client.ovpn .
+scp -P 2222 myusername@mydomainname:/home/myusername/stunnel* .
+</pre>
+</div>
+
+<p>
+You will need to ensure that the <i>openvpn</i> and <i>stunnel</i> packages are installed. On an Arch based system:
+</p>
+
+<div class="org-src-container">
+<pre class="src src-bash">sudp pacman -S openvpn stunnel4
+</pre>
+</div>
+
+<p>
+Or on a Debian based system:
+</p>
+
+<div class="org-src-container">
+<pre class="src src-bash">sudo apt-get install openvpn stunnel4
+</pre>
+</div>
+
+<p>
+Now you can connect to your VPN with:
+</p>
+
+<div class="org-src-container">
+<pre class="src src-bash">sudo stunnel stunnel-client.conf
+sudo openvpn client.ovpn
+</pre>
+</div>
+
+<p>
+You should see a series of messages with "<i>Initialization Sequence Completed</i>" showing at the end. Leave the terminal open and perhaps minimize it to remain connected to the VPN. To leave the VPN close the terminal window.

+<h2 id="orgc7282cd">Changing port number</h2>
+<div class="outline-text-2" id="text-orgc7282cd">
+<p>
+Avoiding censorship can be a cat and mouse game, and so if the port you're using for VPN gets blocked then you may want to change it.
+</p>
+
+<div class="org-src-container">
+<pre class="src src-bash">ssh myusername@mydomainname -p 2222
+</pre>
+</div>
+
+<p>
+Select <b>Administrator controls</b> then <b>App Settings</b> then <b>vpn</b>. Choose <b>Change TLS port</b> and enter a new port value. You can then either manually change the port within your VPN configuration files, or download them again as described in the <a href="#org2cfcc49">Usage</a> section above.
+</p>
+</div>

+<h2 id="orgbe4ddea">Generating new keys</h2>
+<div class="outline-text-2" id="text-orgbe4ddea">
+<p>
+It's possible that your VPN keys might get lost or compromised on your local machine. If that happens you can generate new ones from the <b>Administrator controls</b> by going to <b>App Settings</b> then <b>vpn</b> then choosing <b>Regenerate keys for a user</b> and downloading the new keys as described in the <a href="#org2cfcc49">Usage</a> section above.
