Why do manual changes made to '/etc/resolv.conf' files get overwritten on Red Hat Enterprise Linux ?
Issue
- System can ping with IP but can't ping with hostname
- System doesn't properly configure nameserver info
- Using static network and can't set nameserver information
- Changes to resolv.conf being overwritten between boots
/etc/resolv.conf
created during kickstart install is changed- Server unaccessible via network after being rebooted
- For some unknown reason the
/etc/resolv.conf
file keeps getting wiped clean every other week.
Environment
- Red Hat Enterprise Linux 5
