Hi.

We found a reproducable bug with NetworkManager. In the end you have a

connection but resolv.conf is empty and.

How to reproduce:

* establish a mobile broadband connection (make sure everything else is

disconnected)

* Connect to ethernet in parallel

* disconnect from mobile broadband connection

* check /etc/resolv.conf. The file will not contain any dns server

Please tell me if you need further information.

I can't reproduce with the new NM 0.8.1 release using plain resolv.conf.

Are you using a system with resolvconf or netconf enabled?

Dan, What do you mean with a resolvconf or netconf enabled System?

i.e. Debian (resolvconf) or SUSE (netconf).  If you have the resolvconf

or netconf binaries installed, then you're probably using them.  If you

don't, then NM is probably set up to talk directly to /etc/resolv.conf.

Ah, ok. I checked my ubuntu based system. There is no netconf or resolvconf Package installed.

Ok, at this point we need to do more debugging internally then.  Are you
able to rebuild the Ubuntu NM package?  If so, please do that and see if
you can reproduce the problem.  If you can still reproduce it with your
rebuilt package, then we can add a patch to print out what's going on in
src/named-manager/ and isolate your issue.

Sure. It's build from git source by us.
