Re: every reboot screws up my network

Like I said, personal experience on a server.

If you express an opinion then you should also provide reasons for
this opinion.

It might be due to this brilliant thing called networkmanager which was probably invented for laptops using dhcp, but it will readily overwrite your resolve.conf with an empty one on a static ip machine. (If someone can explain the logic behind that please let me know!) It bit me really hard on a remote server that i manage... it lost all access to the outside world. Google for "resolv.conf networkmanager". I think the 'solution' is to make resolv.conf non-writeable for root.

If I ever meet the guy who implemented this networkmanager I'm inclined to do something evil to him!

Running 11.04 and every time I reboot, resolv.conf gets screwed up.
I've tried a couple of different things, but none of them works...

1) changed the IPv4 settings from network tools to do "automatic
(dhcp) addressed only" and set the DNS servers and Search domains

2) modified /etc/resolv.conf/resolv.conf.d/head to specify the
appropriate search and nameserver directives

After a reboot /etc/resolv.conf is no longer a symlink and does not
contain any nameserver entries (it does have the proper search

I can manually re-establish the symlink and things work properly, but
that's obviously not a viable long term solution...

Any ideas?


Is this on a server Bruce? I had the same problem with my server
install and the fix was to put a newer resolv.conf (from 12.04) package
in. Unfortunately I didn't save the instructions but if you can search
this list you should be able to find the thread. I don't have that many
posts so you could search for my name. I think it was about 3 or 4
months ago.

It's version 1.63ubuntu3 of resolvconf.

Thanks Knute, I'll give that a try. FWIW, it's a desktop, not a server,
running as a VM (vmware).
