How to setup Cisco VPN using VPNC Ubuntu Jaunty (9.04)

This guide is for ubuntu users who want to connect to Cisco VPN. We will be using VPNC (it is in ubuntu 9.04 repo). This guide assumes you have profile file in .pcf format (we will use cisco.pcf as an example here).


Let’s begin and follow the steps exactly replacing your own pcf file:
Open terminal and run the following commands
* Create a directory
mkdir vpnclient
Change to that directory:
cd vpnclient
* Download cisco-decrypt file which will be used to decrypt the group password from your pcf file:
wget http://www.debuntu.org/files/cisco-decrypt.c
sudo apt-get install libgcrypt11-dev
gcc -Wall -o cisco-decrypt cisco-decrypt.c $(libgcrypt-config --libs --cflags)
chmod +x cisco-decrypt
sudo cp cisco-decrypt /usr/bin
* Download pcf2vpnc to convert pcf files in vpnc configuration format
wget http://svn.unix-ag.uni-kl.de/vpnc/trunk/pcf2vpnc
chmod +x pcf2vpnc
sudo cp pcf2vpnc /usr/bin
* Go to windows vpn profiles directory and convert .pcf files to .conf files
pcf2vpnc cisco.pcf > cisco.conf
Note:replace above cisco.pcf with your own .pcf file.
sudo cp cisco.conf /etc/vpnc/
* install vpnc and connect to vpn
sudo apt-get install vpnc resolvconf
sudo vpnc cisco
Enter username for <vpn> :

Enter password for <vpn>:

VPNC started in background (pid: 6092)…
* To disconnect simply do
sudo vpnc-disconnect
After your VPN has been established then connect to your remote desktop
Go to Applications >> Internet >> Terminal server client
Or
In terminal run
tsclient
Credir goes here
