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.

|
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.

<div class="outline-text-2" id="text-org2cfcc49">

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.
|
|

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

</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.

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.
