Installing Cisco VPN on Mandriva 2008

As you are following the standard procedure to install the Cisco VPN client you will come to an instruction which says you must run

./vpn_install

Stop

Have you tried that already and seen errors like

• when you start the vpn service

  cisco_ipsec.ko -1 Invalid module format

• dmesg shows errors like

  $dmesg | grep cisco
  cisco_ipsec: version magic '2.6.22.9-1mdvcustom SMP mod_unload 686 ' should be '2.6.22.9-laptop-1mdv SMP mod_unload 686 '

?

Then you should check that your kernel source version agrees with your kernel version. For example, my kernel version was

$ uname -a
Linux localhost 2.6.22.9-laptop-1mdv #1 SMP Thu Sep 27 04:17:10 CEST 2007 i686 Intel(R) Pentium(R) M processor 1600MHz GNU/Linux

And my kernel source showed:

$ grep "EXTRAVERSION =" /usr/src/linux/Makefile
EXTRAVERSION = .9-1mdvcustom

• 2.6.22.9-laptop-1mdv
• 2.6.22.9-1mdvcustom

This must be fixed before proceeding with vpn installation

$ cd /usr/src/linux
$ sed -i -e"s/EXTRAVERSION = .9-1mdvcustom/EXTRAVERSION = .9-laptop-1mdv/" Makefile
$ make oldconfig
$ make modules_prepare
$ make prepare
$ cd /usr/local/src/vpnclient

We now return you to the main procedure

$ ./vpn_install
