Description Need Real Name 2010-12-05 13:15:37 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):

NetworkManager-0.8.1-10.git20100831.fc14.x86_64

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.

How reproducible:


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
3. reboot
  
Actual results:

'hostname' returns localhost.localdomain by the time the user logs in

Expected results:

'hostname' ALWAYS returns the value set in /etc/sysconfig/network

Additional info:

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?
Comment 2 Pierre Ossman 2010-12-16 02:25:56 EST
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. :/
Comment 3 Dan Williams 2011-02-25 14:08:25 EST
NM no longer touches /etc/hosts so we shouldn't run into this problem anymore.
