Fedore Core 7 Forgets Its DNS Settings on Reboot

[Andrew Kaplan]

Hi there --

I have a Fedora Core 7 server that loses its DNS settings on system reboot. The /etc/resolv.conf file does not maintain its entries even though they are entered by the root user.

The workaround that I have implemented involves the resolv.conf file saved under a different name, and a symbolic link under the appropriate name pointing to the other file. While this works, it does not fix the original problem.

Has anyone seen this, know what the cause is, and how it can be fixed? Thanks.

What happens to the file, is removed, exists but it's empty or the values are changed?

This could be for some interface having ONBOOT=YES and DHCP as the protocol. Check your /etc/sysconfig/network-scripts/ifcfg-* files.

Another troubleshooting technique could be to enable auditing over the file.

It's some "generated by dhclient" comment in there?
