Bug Description

Binary package hint: network-manager-pptp

PPTP VPN connections fail always for me. I confirmed using wireshark that there's not even any traffic to the PPTP gateway.

I am testing on Jaunty Alpha 6 (32-bit)

uname -a
Linux kleber 2.6.28-9-generic #31-Ubuntu SMP Wed Mar 11 15:43:58 UTC 2009 i686 GNU/Linux

Steps to reproduce: Add PPTP VPN connection using gnome Network Manager. I have not found a combination of PPTP settings that did not cause this error to occur.

Sometimes, the OSD displays something about missing 'secrets'. Every time I try to click on my VPN connection, I get the following error in /var/log/syslog:

 switching betwen local wireless networks, it's also useful on desktops
 with a selection of different interfaces to use. It is not intended for
 usage on servers.

 This package provides a VPN plugin for PPTP, commonly used for connecting
 to Microsoft VPN servers.

This bug is no longer affecting me. After downloading several updates to the Jaunty Alpha series, the VPN is working for me.

This bug was fixed in the package network-manager-pptp - 0.7.1~20090213+bzr15-0ubuntu2

---------------
network-manager-pptp (0.7.1~20090213+bzr15-0ubuntu2) jaunty; urgency=low

  * Add lp343270_dbus-permissions.patch: update dbus permissions so PPTP
    works for at-console user again (LP: #343270).
  * debian/control: add missing libglade2-dev Build-Dep.

Please restart NetworkManager.

Yes, restarting "fixed" it.

Should have checked that in the first place, didn't remember seeing an update to network-manager-pptp. Sorry about that.

My fix for this issue was not correct. It is being reverted by asac since it is not needed. I have confirmed that losing the at_console stanza is no longer needed.
