Cisco VPNClient in Ubuntu Feisty Fawn

Ubuntu Feisty Fawn use Linux kernel version 2.6.20. This version is new, and unfortunately is not supported by Cisco VPNclient. However, there is a patch for Cisco VPNclient, so it can be compiled successfully for Feisty Fawn.

# change directory to Desktop
cd ~/Desktop

# download Cisco VPNclient (latest version)
wget ftp://ftp.cs.cornell.edu/pub/rvr/upload/vpnclient-linux-4.8.00.0490-k9.tar.gz

# download patch (latest version)
wget http://tuxx-home.at/projects/cisco-vpnclient/vpnclient-linux-2.6.22.diff

# extract vpnclient
tar -zxvf vpnclient-linux-4.8.00.0490-k9.tar.gz

# apply patch
cd vpnclient
cp ../vpnclient-linux-2.6.22.diff .
patch < vpnclient-linux-2.6.22.diff

# install patched vpnclient
sudo ./vpn_install

# start vpnclient
sudo /etc/init.d/vpnclient_init start

Next steps :
If you already have *.pcf files, then copy all *.pcf files into /etc/opt/cisco-vpnclient/Profiles/

To start the VPNclient session, then you could open gnome terminal and type the following command :

vpnstart connect MyProfile

NOTE
After vpnclient started, then I can't open rdesktop session to my XP VM. However, I can access the samba shared from the XP VM (via console). Weird.... (I'll troubleshoot it later when I have time).
