How do I add OpenVPN client to Ubuntu?

Is there a way I can just add an openvpn client to Ubuntu (by installing an OpenVPN client and setting up the file on my Raspberry PI) and have it work without installing full Ubuntu, setting up the software and setting up the entire VPN client program? Yes, there's a way. The only software that does everything for you is StrongSwan, but it requires a little configuration. I'll detail the steps here, assuming you already have a RPi set up and running Ubuntu.

Install OpenVPN in Ubuntu. Open the terminal and type: sudo apt-get update. Sudo apt-get install network-manager-strongswan strongswan-openvpn-plugin. Sudo service strongswan restart. Sudo systemctl restart strongswan. To download your OpenVPN public/private keypair, use: curl -s config/strongswan/config/strongswan.conf (see the link above) as so: # This must match the public key from your VPN server. Ca-certificate=~/.ssh/idrsa.pub
# The password to log into the VPN server, as obtained during. # account-req or using some GUI. Set this if no credentials provided pass-udp-tunnel=password. # Port for authentication. Auth-port=1194. # Which IP addresses to allow to tunnel traffic over the VPN. Ifconfig-push="eth0 192.168.1"
Save the .conf file.

Enable the "strongswan"-interface. From the SSH connection, in a separate terminal or console window: sudo dhclient . This step is where it gets a bit tricky. For most modern routers, you should be able to set your local and remote interfaces up as "autoconfigured", ie: static interface strongswan. Static interfaceipv6. You should then be able to just restart the daemon and it should work, even when the rest of the network isn't using OpenVPN, such as when other routers are down.

How do I install OpenVPN client?

I have a computer running Windows 7 and I want to install OpenVPN client to that machine.

Now I have OpenVPN installed but I don't know how to open the GUI of it. It's not listed in the "open with" dialogs. How do I do it?

Start OpenVPN. The OpenVPN GUI should already be running. Click "Open" and select your OpenVPN binary and the name you gave to the OpenVPN service. If it asks for your login credentials, enter them. If you want to use the OpenVPN GUI to config, logout of it first or just run a "killall -HUP openvpn" on the terminal window.
