I’m sure it’s something to do with copy/paste or my blog prints it differently. I’m trying to paste the command here again. Copy everything inside the “”.
“sudo sed -i ’s/const\ struct\
net_device_ops\ \*netdev_ops;/struct\
net_device_ops\ \*netdev_ops;/’ `find /usr/src -name netdevice.h`
“

anyone have any isakmp key refresh problems with vpnc on 9.04?

vpnc used to work great on 8.10, but on 9.04, (1) the gui does not correctly update resolv.conf, so you have to launch from cmd line and (2) isakmp key refresh seems to not work, so the connection drops at key refresh time.

any advice would be much appreciated!

cheers.

Thanks so much. VPNC works well on my Ubuntu 9.04 laptop. The Cisco Vpn client that I had installed initially always dropped the connection after a few minutes and it didn’t work with dual cores. Vpnc seems to be working fine.

after vpnc
If you get error:
vpnc was built without openssl: Can’t do hybrid or cert mode

It is because you are probably using copy of example.conf which has IKE Authmode Hybrid

The right option is
IKE Authmode psk
which is default choice so you can delete this row.
vpnc: response was invalid [1]: (ISAKMP_N_INVALID_EXCHANGE_TYPE)(7)
It is because you false settings of authentication (hybrid instead of psk) so you have to change your .conf file as above meantioned.

I hope this helps.
If you try install open-ssl support for vpnc you get error

You sir, are a saint. This worked great! Nice to get away from Cisco’s VPN that crashes my system every time.

@Dwight Probably a bit late, but on your Windows install with the Cisco client, you should be able to locate the .pcf for his network either under Program Files where the client is installed or in your Documents and Settings directory under one of the application settings directories.
