Two ways: Edit the /etc/sysconfig/network-scripts/ifcfg-<whatever> script for the interface associated with the router providing the bad info and add the line: PEERDNS=no You might have to reboot a couple of times after that to get the network properly shutdown and restarted with the PEERDNS=no line in place. After the reboots, it should be safe to manually edit /etc/resolv.conf and the contents should remain undisturbed from that point on. If that doesn't fix it, there is always the big hammer: Edit /etc/resolv.conf the way you want it, then do: chattr +i /etc/resolv.conf That sets the "immutable" attribute so even root can't modify the file. (If you ever want to modify it again, you'll need to do chattr -i first). P.S. This only works for redhat based distros. The rules to achieve the same PEERDNS=no effect on other distros vary wildly (the most wacko being opensuse). -- users mailing list users@lists.fedoraproject.org To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines
