I've got the Linux AnyConnect VPN client working, but after some struggles. I get the same problems with Ubuntu Feisty and Gutsy, and just wanted to check if anybody else was running in to these problems:
1) When trying to do a web launch, it says I need a plugin called GCJ, but I can't find any evidence this plugin exists.
2) The timestamps on all the installation files are marked December of 2008, which causes all kinds of fun error messages.
3) /opt/cisco/vpn/bin/vpnagentd is supposed to run automatically at startup, but this doesn't appear to be working. I have to manually start it every time.
Client works just dandy on Windows, but having a nice fully supported graphical VPN client is one of the reasons we're moving to AnyConnect
