Network Manager VPN Connection blanks /etc/resolv.conf

[Steve Brown]

Binary package hint: network-manager

Configure a PPTP VPN Connection in Network Manager.

Choose the option Use-Peer-DNS under PPP Options tab.

Make connection to VPN server.

cat /etc/resolv.conf and notice that peer's DNS is set correctly as the nameserver entry.

Terminate VPN connection

Reconfigure VPN Connection and remove tick from Use Peer DNS option under PPP tab

Reconnect VPN.

/etc/resolv.conf is now completely blank (except for a # generated by NetworkManager, do not edit! line), rendering name resolution inactive and generally stuffing anything you might want to do on the net!

Worked correctly under Edgy - not working correctly on Feisty.

I can confirm the same behaviour on 7.04 with network-manager version 0.6.4-6ubuntu7 and network-manager-pptp version 0.6.3+cvs20060819-0ubuntu2.

I followed the steps described by the initial reporter and achieved the exact same result.
