I've been successfully using vpnclient-linux-x86_64-4.8.00.0490-k9
from Cisco on a Fedora Core 5 x86_64 computer, but
kernel-2.6.20-1.2312.fc5 no longer plays nicely with it.
It did work fine with 2.6.18-1.2257 from January.

Firstly, I had to install the patch from
http://www.tuxx-home.at/archives/2006/12/07/T09_36_48/
which makes it possible to compile the vpn package, albeit with a few
warnings. I end up with a module that the kernel accepts, but trying
to open the vpn connection always fails with the rather cryptic error
message "Failed to establish a VPN connection" without producing
anything else in the system logs.

Suggestions, anyone?
