I had difficulties installing Cisco5.0 VPN on my Ubuntu 10.04 LTS. I asked for assistance in this question: link to previous question. The answer is that this Cisco program will run on only older versions of the kernel.
I would like to use the VPN to connect through my university's network so that I can view academic journals under their subscription. One option could be to downgrade the kernel; how can this be done and what consequences would this have? The second question is whether I can install an alternative VPN client to connect? I have a ".pcf" file from the university to use with the Cisco client. Would this be compatible information to allow another client to connect? Is the connection independent of the software used?
