Why do manual changes made to '/etc/resolv.conf' files get overwritten on Red Hat Enterprise Linux ?

Solution Verified - Updated -


  • 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.
