Install vpnc

Update vpnc-script

After vpnc is installed you must replace vpnc-script with new version. Ubuntu vpnc package installs old vpnc-script, which results in following error: Error: either "to" is duplicate, or "ipid" is a garbage.

Open terminal and then enter the following commands: 

   sudo su
   chmod 777 /etc/vpnc
   cd /etc/vpnc
   mv vpnc-script vpnc-script.old
   wget http://tinyurl.com/vpnc-script
   chmod 777 vpnc-script
