Just a few notes on getting the Cisco VPN to work on Ubuntu
- Excellent step by step instructions here
- Make sure that all the profiles in /etc/opt/cisco-vpnclient/Profiles/ are readable and writable by all users (chmod a+rw *.pcf)
- Disable all unused network interfaces. For example, when I used my wifi card (eth1), I disabled the wired interface (eth0) with “ifconfig eth0 down”
