I thought NM had a know bug where it did not yet respect the
PEERDNS=no
entry.
Has this been fixed?
The only (and most unfortunate) way I have been able to reliably keep
my
resolf.conf file from getting waxed by NM has been to set it as
immutable. A _very_ nasty way of doing things, but it does work.
Cheers,

Problem persists. Have had several batches of patches pushed through
yum auto update, but nothing concerning NM to fix this problem.
I set PEERDNS=no with no affect.
I set /etc/resolv.conf to a workable solution and then removed the write
bits and set it immutable. I get errors in /var/log/messages about it,
but the behavior is still the same. After a reboot, all is OK. After a
while, dns dies. Restarting NM brings it back to life...then it dies a
few minutes later. As long as someone is actively accessing the net,
dns seems to stay up. But give it a few minutes of idle time and
something causes it to stop. Here is a snapshot of /var/log/messages
before, during, and after a NM restart. Can anyone figure out what is
going wrong with dns?

The error message concerning /etc/resolv.conf is due to the removal of
write bit and setting it immutable. NM does create a file called
/etc/resolv.conf.tmp which appears to be a copy of my immutable
