BUT, the problem seems to be, that after I set it so network didn't

removed each time anyway and this is a bug?
The /etc/resolv.conf file does indeed get emptied (file exists, just no
info) upon shutdown/boot up. Although the one
in /etc/sysconfig/networking/profiles/default/resolv.conf file is filled
out but I am guessing not ready by NM. Soooo, I thought I read about
the ifcfg-ethx file having dns info inside it? IF so, what paramaters
are used to list it there? DNS seems to be about the only thing so far
from NM being completely usable and no configuring at all.
Other thatn that, all is well and services seem to start. ALTHOUGH, I
have experienced that on shutdown, while shutting down quotas, it stays
there and never goes away? Cold boot after to get it going.
Edit /etc/sysconfig/networking/devices/ifcfg-ethx and add DNS1, DNS2,
DNS3, and set PEERDNS=no and networkmanager should pick up and reset
your resolv.conf based on those cfgs and which is configured (i.e. diff
interfaces could have diff nameservers). Also see the thread:
Re: f9 resetting dns nameservers
NM does not seem to honor PEERDNS=no
What's the expected behavior there for ifup?
/usr/share/doc/initscripts-*/sysconfig.txt :
PEERDNS=yes|no
modify /etc/resolv.conf if peer uses msdns extension (PPP only) or
DNS{1,2} are set, or if using dhclient. default to "yes".
DNS{1,2}=<ip address>
provide DNS addresses that are dropped into the resolv.conf
file if PEERDNS is not set to "no".
PEERDNS=no : do not touch /etc/resolv.conf at all...
> For NM, the way it
_should_ currently work is:
1) if using DHCP; DNS1..3 will override whatever the DHCP server sends
you
2) if using static: you must specify DNSX or else you won't get DNS
servers
The problem is that we can't pull DNS servers from the existing
resolv.conf, because stuff rewrites resolv.conf. We need to store DNS
information in the ifcfg files so that when more than one connection
gets brought up, we can merge the information from both of those
connections into a suitable resolv.conf.
What might be a good thing to do is honor PEERDNS=no for a
connection/ifcfg such that NM just won't use anything that an automatic
configuration method (like DHCP or PPP) returns for that connection.
