resolv.conf changing everytime network restart

cuco76 · 11-29-2004, 02:50 PM

Hello,

I am running Fedora Core 3. I need to have a few DNS Search Paths in my /etc/resolv.conf. If I add them directly or by way of system-config-redhat they disappear after a reboot or if I do a $service network restart. I believe dhcp is putting the defaul one in and removing the others. Does anyone know of a way around this?

Thanks in advance!

Chris

yeah this is part of the DHCP specifications, you'll need to add a command line flag to your dhcp client, normally there's a DHCPARGS variable, which you would specificy in /etc/sysconfig/network-scripts/ifcfg-eth0. if you're using dhcpcd, it's the -R option, but this will proabbly vary on othter clients, e.g. pump, dhclient, dhcpxd check tha relevant manpage for your option.

Try putting

Code:

request subnet-mask, broadcast-address, time-offset, routers;

in your dhclient.conf. Further information can be found in man dhclient.conf

The best way is probably to edit your dhclient-script (probably /sbin/dhclient-script) and comment out all the lines in the "make_resolv_conf" function - leave the function itself though.

Thanks David,

I commented the sections relating to make_resolve_conf. Works like a champ. I will just have to keep an eye on the nameservers just in case they change!

Thanks again!
