Description Jay Fenlason 2006-12-05 18:43:38 UTC 
Description of problem: 
Old static config in /etc/sysconfig/network-scripts/ifcfg-eth0 prevents

Version-Release number of selected component (if applicable): 
initscripts-8.45.4.EL-1 
 
How reproducible: 
 
 
Steps to Reproduce: 
1.Configure a rhel4 box with a static IP configuration, then change the 
configuration to use DHCP. 
2.Upgrade the box to rhel5 
3.Observe that the box can no longer access machines beyond the local network. 
   
Actual results:

Comment 1 Bill Nottingham 2006-12-05 18:53:23 UTC 
What are the config files?

old ifcfg-eth0

Removing the last three lines "fixed" the problem, but it's still a regression
from RHEL4.
Comment 3 Bill Nottingham 2006-12-06 20:29:17 UTC 
This is done in dhclient-script (*yuk*).
Comment 4 RHEL Program Management 2007-07-23 15:38:36 UTC 
This bugzilla has Keywords: Regression.  

Since no regressions are allowed between releases, 
it is also being proposed as a blocker for this release.  

Please resolve ASAP.
Comment 5 James Laska 2007-11-02 16:55:51 UTC 
What's the proposed solution here?  Is dhclient-script being changed to honor
BOOTPROTO over IPADDR?
Comment 6 Dave Cantrell 2008-01-07 18:48:56 UTC 
This this isn't happening in dhclient-script, it happens in anaconda.  On
upgrade, we're preserving everything in the existing ifcfg-ethX file, which
shouldn't be happening.  Attached is a patch to fix the problem.

Comment 10 Milan Zázrivec 2008-02-06 11:58:17 UTC 
Upgrade from RHEL4.6 AS to RHEL5.2-Server-20080206.nightly according to 
scenario in comment 0 works as expected.
