UF VPN - Ubuntu Karmic Koala installation notes
==========================================

I decided to use the VPNC client in Ubuntu Koala, and followed this:
http://www.stat.ufl.edu/system/vpn.shtml

Steps: 

1. sudo apt-get install vpnc network-manager-vpnc
2. In network connections->VPN connections->configure VPN
add a new entry:
connection name: UF VPN
gateway: vpn.ufl.edu
group name: vpn-auth
user password: <your gatorlink password>
In optional settings: add username as your <gatorlink>@ufl.edu

3. Login using Gatorlink at:
http://net-services.ufl.edu/cgi-bin/vpn/vpn-clients.cgi
scroll down and download the configuration file: ufl-vpn.pcf

copy paste the "enc_GroupPwd" field into:
http://www.unix-ag.uni-kl.de/~massar/bin/cisco-decode

and get the "clear:" password and put that value into the "group password" field (in configure VPN box). Save the password in the keyring by using password "saved" option.

4. click apply and connect with the UF VPN now. Voila!

Update: 28 JUne 2010
On Lucid Lynx, you have to restart network-manager after adding the passwds, using:
sudo service network-manager restart




To perform step-2 using the command prompt:
$ sudo vpnc
Enter IPSec gateway address: vpn.ufl.edu
Enter IPSec ID for vpn.ufl.edu: vpn-auth
Enter IPSec secret for vpn-auth@vpn.ufl.edu: <clear:> field from the second link in step-3 above
Enter username for vpn.ufl.edu: <gatorlink>
Enter password for ganeshv@vpn.ufl.edu: <gatorlink passwd>
VPNC started in background (pid: 10285)...
