We have VPN (Virtual Private Network) access at work which I use often when I need to get at files whist I’m at home or abroad. To use VPN under Ubuntu Linux is simple; all you need to do is install pptp support for network manager to enable VPN support. Run the following command in an xterm:
sudo apt-get install network-manager-pptp
sudo killall nm-applet
sudo /etc/init.d/dbus restart
nm-applet –sm-disable &
Left click on the network manager applet on the top right of your desktop and select VPN Connections->Configure VPN. From here configure your VPN details as normal. To connect to your newly setup VPN left click on the network manager applet again and select VPN Connections->your_vpn_connection.
