I am trying to connect to a PPTP VPN on my Ubuntu 10.10 computer but it seems to fail. I have tried successfully to connect to the VPN on a OS X machine and it did work.

I connect using the NetworkManager applet and the VPN seems to think that I am connected for a while before it closes down again and tells me that the connection fails.

When I look in my /var/log/syslog this is what I find:

Clio NetworkManager[1208]: <info> Starting VPN service 'org.freedesktop.NetworkManager.pptp'...

Thus it seems to be able to connect to the VPN but encounters some sort of problem when invoking the script:

Clio nm-dispatcher.action: Script '/etc/NetworkManager/dispatcher.d/01ifupdown' exited with error status 1.

Anyone have any idea on how to fix this?
