Trying to get company VPN installed onto 11.3 ... I had this running under 11.2 ... I've been following other threads and tutorials in trying this ... I unzip the vpn, and patch using the 2.6.31-final.diff patch ... I get:

vpnclient # patch < ./vpnclient-linux-2.6.31-final.diff
patching file interceptor.c
Hunk #1 succeeded at 192 with fuzz 2 (offset 72 lines).
Hunk #2 FAILED at 136.
Hunk #3 FAILED at 276.
Hunk #4 FAILED at 299.
3 out of 4 hunks FAILED -- saving rejects to file interceptor.c.rej

Pretty sure I need all 4 lines patched ... but I try to install anyway and get:

Setting permissions.
/opt/cisco-vpnclient/bin/cvpnd (setuid root)
/opt/cisco-vpnclient (group bin readable)
/etc/opt/cisco-vpnclient (permissions not changed)
* You may wish to change these permissions to restrict access to root.
* The packaged Root Certificate was imported successfully.
* You must run "/etc/init.d/vpnclient_init start" before using the client.
* This script will be run AUTOMATICALLY every time you reboot your computer.

Can anyone advise please?
