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).

Letís begin and follow the steps exactly replacing your own pcf file:

Go to terminal:
* Create a directory:
Code:
mkdir vpnclient
Change to that directory:
Code:
cd vpnclient
* Download cisco-decrypt file which will be used to decrypt the group password from your pcf file:

Code:
 wget http://www.debuntu.org/files/cisco-decrypt.c

Code:
sudo apt-get install libgcrypt11-dev
Code:
gcc -Wall -o cisco-decrypt cisco-decrypt.c $(libgcrypt-config --libs --cflags)
Code:
 chmod +x cisco-decrypt
Code:
 sudo cp cisco-decrypt /usr/bin
* Download pcf2vpnc to convert pcf files in vpnc configuration format

Code:
wget http://svn.unix-ag.uni-kl.de/vpnc/trunk/pcf2vpnc
Code:
chmod +x pcf2vpnc
Code:
sudo cp pcf2vpnc /usr/bin
* Go to windows vpn profiles directory and convert .pcf files to .conf files

Code:
pcf2vpnc cisco.pcf > cisco.conf
Note:replace above cisco.pcf with your own .pcf file.

Code:
sudo cp cisco.conf  /etc/vpnc/
* install vpnc and connect to vpn

Code:
sudo apt-get install vpnc resolvconf
Code:
sudo vpnc cisco
Enter username for <vpn> :
Enter password for <vpn>:
VPNC started in background (pid: 6092)...

* To disconnect simply do

Code:
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
Code:
tsclient
Goodluck
