I am trying to setup a vpn connection in Ubuntu 10.04 to use the service from relakks.com

I used the network manager to add the vpn connection and the settings are:

Gateway: pptp.relakks.com
Username: user
Password: pwd

IPv4 Settings: Automatic (VPN)

Advanced:

MSCHAP & MSCHAPv2 checked

Use point-to-point encryption (security:default)
Allow BSD data compression checked
Allow deflate data compression checked
Use TCP header compression checked

The connection always fail, here is the syslog:

Does someone can identify something in the syslog? I've been googling and reading about pptp but couldn't find anything about the error "read returned zero, peer has closed"

Did you select those options, or are they the defaults? (defaults worked beautifully for me with that release with a MS PPTP VPN) –  Grizly Jun 27 '10 at 23:53

I get the same errors with default settings. –  fazpas Jun 28 '10 at 1:00
