Red Hat Bugzilla – Bug 501386
DNS settings are cleared on system restart
Last modified: 2009-05-21 20:43:45 EDT
Description of problem:
DNS settings, to appear in resolv.conf, are cleared to nothing on system boot.
Version-Release number of selected component (if applicable):
system-config-network 1.5.93 is where I see the results.
I assume the bug is actually in NetworkManager, but don't know exactly.
Use the GUI to set the DNS, then reboot. Fails every time.
Steps to Reproduce:
1.Go to System, Administration, Network, click on DNS tab, enter primary and secondary DNS addresses.
2. Save configuration. You will see it in both the default resolv.conf and /etc/resolv.conf .
3. Shutdown restart the system.
DNS will be missing in all places mentioned.
No commands, such as "host", that try to access DNS will work.
The DNS IP addresses entered will remain so, and show up in resolv.conf .
NetworkManager is running, one interface is activated and controlled by it.
1. There is another bug reported in which the DNS settings are lost.
2. The bug does not occur if NetworkManager is disabled.
3. There is another bug in which interfaces do not activate on boot, unless they are controlled by NetworkManager. It is reported by another user that the bug does not occur if NetworkManager is uninstalled. Merely disabling it does not fix that problem.
Hint: NetworkManager needs serious attention or even removal from the distribution.
Thank you for the bug report. This particular bug has already been reported into our bug tracking system, but please feel free to report any further bugs you find.
