vpnc plugin: order of resolv.conf entries when using Mobile Broadband vs. (W)LAN

[Marc Luethi <netztier bluewin ch>]

Hi all

I am running Ubuntu 8.10 with ...

network-manager		0.7~~svn20081018t105859-0ubuntu1.8.10.1
network-manager-gnome	0.7~~svn20081020t000444-0ubuntu1.8.10.1
network-manager-vpnc	0.7~~svn20081015t024626-0ubuntu1

... to build a VPN tunnel to the Cisco PIX at my home.


When using a public WLAN hotspot or some other form of (W)LAN
connectivity, /etc/resolv.conf looks like this after the VPN Tunnel is
up:

  nameserver <my home DNS IP>
  nameserver <hotspot LAN DNS1 IP>
  nameserver <hotspot LAN DNS2 IP>
  search <my private home domain>  

This is exactly I want it to be (VPN connection's DNS listed first), so
I can resolve internal names of my home LAN. 

Using the very same VPN connection entry, with either of my two
(swisscom) mobile phones to connect via "Mobile
Broadband", /etc/resolv.conf gets updated in a different way:

  nameserver 138.188.101.186   (dnsscm3.swisscom.com)
  nameserver 138.188.101.189   (dnsscm4.swisscom.com)
  nameserver <my home DNS IP>
  search <my private home domain>


This is unlucky, because now the mobile broadband ISPs get queried
first, and of course they wouldn't know anything about my private home
domain - and I can't resolve names in there.


Is this intentional, or can it be configured somewhere?

regards
