I installed Ubuntu 9.10 on my computer, and very shortly after realized that I cannot connect to my VPN connection at work. The Cisco VPN client apparently has some issues installing on Kernel 2.6.31, for amd64 (although I’ve seen plenty say it doesn’t work on x86 either).
So here is what I found (and did) to make it work…
Download the vpnclient-linux-x86_64-4.8.02.0030-k9.tar.gz
Untar the files
tar zxf vpnclient-linux-x86_64-4.8.02.0030-k9.tar.gz
