NetworkManager ignoring /etc/sysconfig/network hostname, using localhost.localdomain instead
Last modified: 2011-02-25 14:08:25 EST
Description of problem:
We have noticed recently that NetworkManager is ignoring or otherwise overriding /etc/sysconfig/network hostname settings. We set an FQDN there, but after reboot and logging in via GDM, it has changed to localhost.localdomain. We are using wireless with DHCP by default, and these are multi-homed laptops. They are often booted on different networks and/or suspended on one and resumed on another.
Version-Release number of selected component (if applicable):
but we think this has been going on for a while, so it probably isn't specific to that version. It also occurs on an up to date F13 laptop.
Steps to Reproduce:
1. set a hostname in /etc/sysconfig/network
2. have wireless networks configured in nm-applet with DHCP, shared by all, and on boot
'hostname' returns localhost.localdomain by the time the user logs in
'hostname' ALWAYS returns the value set in /etc/sysconfig/network
I noticed a 'DHCP--Addresses only' option in nm-applet, but that seems to expect manually configured DNS servers. What we expect is to get the network-provided DNS server IPs, but keep our static hostname no matter what.
This didn't occur for me on a fully updated F13, but I upgraded to F14 today and got this bug. :/
Dan, comments? Workaround?
Found the problem here. /etc/hosts had gotten the wrong SELinux context, which upset NM and made it fall back to localhost. I should remember to check the log files before I go complaining in bugzilla next time. :/
NM no longer touches /etc/hosts so we shouldn't run into this problem anymore.
