[ubuntu] Lucid Lynx, 10.04 Cisco VPN

28 05 2010

For those who recently upgraded to Lucid Lynx, and the vpn client seems to have broken when and you get the error below:

Starting /opt/cisco-vpnclient/bin/vpnclient: insmod: error inserting ‘/lib/modules/2.6.32-22-generic/CiscoVPN/cisco_ipsec.ko’: -1 Invalid module format
Failed (insmod)

The solution is rather simple, you just need to uninstall your vpn client and reinstall it again instead of install over the old version. Simple and effective to me 😀

For those who is trying to get the Cisco VPN up and running, head to this page and read all about how to do it.

Looks like Arun’s install instructions no longer work for kernel 2.6.32? Anybody know of workaround?

I worked, but with the new kernel versions 2.6.32-23-generic this solution no longer works. If someone finds a solution, please share it.

Hi Lads,

I got it fixed on my Ubuntu 10.04, kernel 2.6.32-24-generic by modifying the line below on “netdevice.h” (in my case, /usr/src/linux-headers-2.6.32-24-generic/include/linux/netdevice.h):

#################
/* Begin Modified by FabioR
const struct net_device_ops *netdev_ops;
End Modified by FabioR*/

struct net_device_ops *netdev_ops;
#################

I hope it will help you as well.

Cheers,
FabioR
