Install Cisco VPN Client on Ubuntu 10.10

I just upgraded my OS from Ubuntu 10.04 (Karmic Koala) to Ubuntu 10.10 (Maverick Meerkat) yesterday and as usual the Cisco VPN client wasn’t working. So I had to patch it. Below is the *how to* for installing Cisco VPN client on Ubuntu 10.10.
Assuming you already have the Cisco VPN client (vpnclient-linux-x86_64-4.8.02.0030-k9.tar.gz) downloaded. Lets extract it and then enter into the directory.

shuvo@shuvo:~$ tar -zxvf vpnclient-linux-x86_64-4.8.02.0030-k9.tar.gz

vpnclient/
vpnclient/libvpnapi.so
…..
…..
vpnclient/Makefile
vpnclient/AMD-PATCH-README.txt

shuvo@shuvo:~$ cd vpnclient/

Now download the patch and apply it.

shuvo@shuvo:~/vpnclient$ wget http://files.shuvoovuhs.com/fixes.patch

shuvo@shuvo:~/vpnclient$ patch < ./fixes.patch

patching file interceptor.c

patching file linuxkernelapi.c
patching file Makefile

After patching lets install the VPN client!

shuvo@shuvo:~/vpnclient$ sudo ./vpn_install

* You may wish to change these permissions to restrict access to root.
* You must run “/etc/init.d/vpnclient_init start” before using the client.

Now that we are done installing the VPN client lets see if its working :) First start the VPN client.

shuvo@shuvo:~/vpnclient$ sudo /etc/init.d/vpnclient_init start

Starting /opt/cisco-vpnclient/bin/vpnclient: Done

Finally put your .pcf file in /etc/opt/cisco-vpnclient/Profiles/ directory and try to connect.

shuvo@shuvo:~/vpnclient$ vpnclient connect fairfax
