PPTP VPN from Ubuntu cannot connect
- by Andrea Polci
I'm trying to configure under Linux (Kubuntu 9.10) a VPN I already use from Windows.
I installed the network-manager-pptp package and added the VPN under Network Manager.
These are the parameters under "advanced" button:
Authentication Methods: PAP, CHAP, MSCHAP, MSCHAP2, EAP
(I also tried "MSCHAP, MSCHAP2")
Use MPPE Encryption: yes
Crypto: Any
Use stateful encryption: no
Allow BSD compression: yes
Allow Deflate compression: yes
Allow TCP header compression: yes
Send PPP echo packets: no
When I try to connnect it doesn't work and this is what I get in the system log:

The error that sticks out here is "pppd[4932] LCP terminated by peer".
Does anyone has suggestion on what can be the problem and how to make it work?
