I've a problema with the VPA CAble connection of my university... on the website of the university there's a .sh file that set all the variables of the connection in ETC/PPP/PEERS and another .sh file that call the connection...I'm on ubuntu 11.10 and when I run the setup.sh I have this error:

impossible to find network-manager-pptp

these are the two file that I had talk about:

#!/bin/bash
echo "Creazione della connessione in corso attendere........."

and the second:

echo -n "Per terminare la connessione premere invio (in alternativa eseguire il commando 'killall pppd'):---->   "

killall pppd


echo "Connessione terminata"

I've correctly installed network-manager-pptp to the latest version...help?
