Cisco VPN

This is how I was able to set up VPNC to connect to a Cisco VPN network.

First of all make sure VPNC is installed. It was in Fedora 9 (vpnc-0.5.1-5).

Then you need to edit the /etc/vpnc/default.conf with the settings for the network you want to connect to. Mine looks like this:
IPSec gateway gateway.to.use
IPSec ID groupname
IPSec secret passwordforgroup
Xauth username myusername
Xauth password mypassword

You can translate the group password here: http://www.debuntu.org/how-to-connect-to-a-cisco-vpn-using-vpnc

To connect simply type $ sudo vpnc
or to disconnect type $ sudo vpnc-disconnect
