Description mark roth 2011-07-13 16:07:14 UTC

+++ This bug was initially created as a clone of Bug #706094 +++

Description of problem:

NetworkManager does not set hostname when DHCP used.

Version-Release number of selected component (if applicable):
Version     : 0.8.9997
Release     : 5.git20110702.fc15

How reproducible:
100%

Steps to Reproduce:
1. Install fedora 15.
2. Ensure /etc/sysconfig/network file has not 'hostname' defined, so have only one line
NETWORKING=yes

Edited the network file, to read:
NETWORKING_IPV6=no
# HOSTNAME=localhost.localdomain
NETWORKING=yes
NTPSERVERARGS=iburst

Actual results:

Did a service network restart

hostname gives localhost.localdomain
Expected results:

Hostname should be imported from DHCP server.
Works in Fedora 14. In messages file we can see the message
'Setting system hostname to...  ... (from address lookup)

At this point, hostname gives localhost.localdomain.

From the original bug:
--- Additional comment from updates on 2011-06-23 23:55:26 EDT ---

NetworkManager-0.8.9997-4.git20110620.fc15 has been pushed to the Fedora 15 stable repository.  If problems still persist, please make note of it in this bug report.

Apparently, as it moved to 0.8.9997-5, this fix was lost.

Yes, this is exactly 719100. Perhaps you did not read the comment that a) I could not reopen but 719100, and b) the fix from 719100 was apparently NOT MERGED into the -5 subrelease, and the bug has returned.

This is a dupe of 719100, and it'll be fixed when the fix for that bug rolls out too in an update.
