| Doc Text: |
Previously, when the system had been rebooted while the network switch had been down, after the network connection was recovered, the network interface configuration was not configured with DHCP, even if the dhclient utility was running in persistent mode. With this update, the dhclient-script file has been amended to refresh the ARP (Address Resolution Protocol) table and the routing table instead of bringing the interface down, which fixes the bug.

Thank you very much for your effort with investigating the problem and back-porting the patch. Yes, the upstream (Fedora) bug for this problem is bug #574568. And as you can see in bug #574568, comment #2 I wasn't able to reproduce the problem on my hardware (it's probably HW specific problem). So, can you confirm that the attached patch fixes the problem reported by customer ? Yes, I confirmed that it fixed the problem in my test machine. I created the test packages for the customer. If they can confirm the fix, I will update it on this bugzilla.
Technical note added. If any revisions are required, please edit the "Technical Notes" field
accordingly. All revisions will be proofread by the Engineering Content Services team.

Previously, when the system had been rebooted while the network switch had been down, after the network connection was recovered, the network interface configuration was not configured with DHCP, even if the dhclient utility was running in persistent mode. With this update, the dhclient-script file has been amended to refresh the ARP (Address Resolution Protocol) table and the routing table instead of bringing the interface down, which fixes the bug.
Tested with dhclient-3.0.5-29.el5 using steps from comment 0. After plugging the cable, dhclient requested an IP address, which was successfully assigned to the network interface and networking started to work. Moving to VERIFIED. An advisory has been issued which should help the problem described in this bug report. This report is therefore being closed with a resolution of ERRATA. For more information on therefore solution and/or where to find the updated files, please follow the link below. You may reopen this bug report if the solution does not work for you. http://rhn.redhat.com/errata/RHBA-2011-1038.html |
