I've made what seemed like promissing changes to /etc/sysconfig/network-scripts/ifup-post and /etc/sysconfig/network-scripts/network-functions . No go. I still get the search line in resolv.conf . I've tried putting in search google.com , but on reboot, it still gives me midco and only midco . Any idea what does affect search in resolv.conf ? How can I fix this so I do not have to manually edit resolv.conf after each reboot. -- Michael hennebry at web.cs.ndsu.NoDak.edu "Sorry but your password must contain an uppercase letter, a number, a haiku, a gang sign, a heiroglyph, and the blood of a virgin." -- someeecards

You want to edit the ifcfg-<interface name> file (replace <interface name> with the name of the network interface) and add PEERDNS=no in the file. This will make it so DHCP doesn't overwrite the resolv.conf. If you just want to hard-code DNS servers, you can either do that in your networkmanager configuration, or add DNS1=9.9.9.9 to the ifcfg file. You can add a second IP with DNS2=1.1.1.1, too. Use whatever DNS IPs you want. This is documented in /usr/share/doc/initscripts-*/sysconfig.txt -- Jonathan Billings <billings at negate.org>
