Well... I can tell you this.... If your ifcfg- contains BOOTPROTO=dhcp and no dhcp server is available the interface won't come up. >> When you bring it down....NM will rewrite it to read.... >> >> # No nameservers found; try putting DNS servers into your >> # ifcfg files in /etc/sysconfig/network-scripts like so: >> # >> # DNS1=xxx.xxx.xxx.xxx >> # DNS2=xxx.xxx.xxx.xxx >> # DOMAIN=lab.foo.com bar.foo.com > NM certainly didn't write that in my ifcfg-wlan0 > or I would have followed its advice. > IIRC, NM simply deleted the nameservers in /etc/resolv.conf > that I had given. That is because that isn't what I wrote.... I wrote that is what is written in /etc/resolv.conf ! I have never seen a case where /etc/resolv.conf was totally "blanked". It either contains the information supplied by DHCP, the information supplied in the ifcfg- file, or the stanza I noted above. > I'm pretty sure I did add DNS1,DNS2 to ifcfg-wlan0 at one point > (I know I added them, but it could have been on another machine), > and it didn't seem to stop NM deleting the nameservers in /etc/resolv.conf . > > My solution which seems to work is to go into NM's Manage Connections, > and give the IP address and nameservers there. > > But I'd have to say that I can't see any point in NM deleting > the nameservers in /etc/resolv.conf . > I can't think of any circumstances in which one would be better off > with no nameservers listed. > It seems to me that the rational action for NM to take > would be to leave /etc/resolv.con as it is > if it cannot find any nameservers where it looks for them. > > Well, if your interface isn't up then it doesn't matter what is in that file in any event. -- users mailing list users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines
