Re: cisco vpn client 4.6 on fedora core 2 2.6.10-1.9_FC2

Hi Teddy,

I have been fighting similar issues. On my system, though, the vpn client hangs the system when I try to start a tunnel under kernel 2.6.9-1.11_FC2. The system does not freeze under kernel 2.6.10-1.9_FC2, but I do get the same compilation warnings, and the tunnel is never successfully created. (I'm using version 4.6 of the vpn client, built from a tarball with "4.6.00.0045-k9" in the name.) For now, I'm keeping a 2.6.8-1.521 kernel around to use when I need a VPN connection. Less than ideal, to say the least.

I'm hoping that Cisco has a newer version of their client software that builds and runs properly under 2.6.10. Failing that, you may be able to use vpnc (http://www.unix-ag.uni-kl.de/~massar/vpnc/). I don't know anything about it, just happened across it.

I got warning and when I ran vpnclient connect myserver
