I have a need to connect to a Cisco VPN for my work, and I need to be able to do it from Ubuntu 10.10. Cisco doesn’t have a client that I can simply install, so I needed another solution. So I found this:http://www.nulldevice.de/2010/06/cisco-client-vpn-vpnc-ubuntu-linux-10-04/
Even though this tutorial is specifically for 10.04, it worked great in my setup. I just copied over my existing configuration file from my Windows 7 box to create the default configuration file.
