This guide is focuses on Ubuntu users who needs to connect to Cisco VPN. We will be using VPNC (it is in Ubuntu 9.04) and assumes you have profile file in .pcf format (we will use cisco.pcf as an example here).
Let’s begin and follow the steps exactly replacing your own pcf file:
Open terminal and run the following commands. Create a directory for our configuration and change into that directory,
mkdir vpnclient
cd vpnclient
