To use Kryptnet on Linux, you will need to do a number of things:

1. Install the OpenVPN network manager package (this will also install OpenVPN for you).
2. Download and save the Kryptnet OpenVPN configuration files.
3. Use the Linux network manager to configure your Kryptnet connection.
4. Connect to Kryptnet
5. Start surfing.

Alternatively, you can install the OpenVPN software package seperately and start the connection from the command line (click here for details).

Please note that, to improve the speed and reliability of your connection, we have set the default connections to use the UDP protocol. This means that your ISP will be able to tell that you are using a VPN connection, but not what you are sending or receiving over it. We have included alternative configuration files that will disguise your VPN connection as normal encrypted web surfing. These are named kryptnet-us.tcp and kryptnet-eu.tcp - you can use these the same way as normal, but be aware that your connection speed may be slower.

Open a terminal window in Linux and enter the following command:

sudo yum install NetworkManager-openvpn

This will install the Network Manager OpenVPN module and all required dependencies, including the correct versions of OpenVPN. If the module is not available for your Linux distribution, please see the faq or contact support.

Ensure that the Network Manager service is running. If it is, you should see its icon at the top-right of your screen. If not, issue the following command in a terminal window:

sudo service NetworkManager restart
sudo chkconfig NetworkManager on

Download the Kryptnet configuration files from here and save them to your hard drive. Extract the contents of the zip file and save them in a known location (for example, create a directory called "kryptnet" in your home directory and extract the configuration files to there).

Open the Network Connections app (in CentOS, click on System, then Preferences, then More Preferences and Network Connections). Click on the VPN tab and the Import button.

In the dialogue that opens, navigate to the directory you saved the Kryptnet configration files to and open either kryptnet-eu.ovpn or kryptnet-us.ovpn - depending on whether you want to connect to the European- or US-based service. This will open a new window which will allow you to edit your connection settings.

Change the Gateway field to either us01.kryptnet.com or vpn01.kryptnet.com, depending on whether you wish to connect to kryptnet through the US or Europe respectively. Enter the Kryptnet user name and password you chose when you signed up to the password, into their respective fields on the window and click on Apply.

Click on the network icon at the top-right of your screen, click on VPN connections, then the name of the VPN connection you created earlier. The icon will flash while connecting, then show a lock symbol when the connection is established.

If you have followed the instructions above, you should now be connected to Kryptnet and can start using the internet anonymously, securely and privately.

To confirm that Kryptnet is doing its job, we recommend you visit a site such as whatismyip.com, where you should see Kryptnet's IP address instead of your own.

Install OpenVPN as per step 1 above, or through yum on the command line (yum install openvpn) or download, compile and install the latest version from openvpn.net. Download the Kryptnet configuration files as per step 2 above. To start your Kryptnet OpenVPN connection, open a terminal window, change to the directory where you placed the Kryptnet OpenVPN configuration files and enter the following command:

sudo openvpn kryptnet-us.ovpn

This will connect you to the US servers. Alternatively, replace kryptnet-us.ovpn with kryptnet-eu.ovpn to connect to the European servers.

Leave the terminal window open while you are using the VPN connection. To disconnect, click on the terminal window and type ctrl-C.
