Description Wouter De Borger 2011-07-22 15:58:53 UTC

Description of problem:

On dual stack networks, with both DHCPV4 and DHCPV6 enabled, DHCPV6 is not attemped when DHCPV4 fails. 

(see /etc/sysconfig/network-scripts/ifup-eth line 210)

Steps to Reproduce:
1. configure both BOOTPROTO=dhcp and DHCPV6C=yes on any eth interface
2. connect the device to an IPV6 only network 
3. ifup the interface
  
Actual results:

DHCPV4 fails
DHCPV6 not started

Expected results:

DHCPV4 fails
DHCPV6 started

Additional info:

running two dhcp clients causes resolve.conf to be overwritten, which may cause unanticipated change of DNS server. IMHO, this is preferable to no DNS at all when the V4 network fails.

Comment 1 Fedora End Of Life 2012-08-07 17:29:59 UTC

This message is a notice that Fedora 15 is now at end of life. Fedora
has stopped maintaining and issuing updates for Fedora 15. It is
Fedora's policy to close all bug reports from releases that are no
longer maintained. At this time, all open bugs with a Fedora 'version'
of '15' have been closed as WONTFIX.

(Please note: Our normal process is to give advanced warning of this
occurring, but we forgot to do that. A thousand apologies.)

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, feel free to reopen
this bug and simply change the 'version' to a later Fedora version.

Bug Reporter: Thank you for reporting this issue and we are sorry that
we were unable to fix it before Fedora 15 reached end of life. If you
would still like to see this bug fixed and are able to reproduce it
against a later version of Fedora, you are encouraged to click on
"Clone This Bug" (top right of this page) and open it against that
version of Fedora.

Although we aim to fix as many bugs as possible during every release's
lifetime, sometimes those efforts are overtaken by events. Often a
more recent Fedora release includes newer upstream software that fixes
bugs or makes them obsolete.

The process we are following is described here:
