Description David Timms 2007-04-17 11:13:33 EDT
Description of problem:
The installer seems to hang - logs suggest it waits up to twenty seconds for a
response for a rdns lookup. 

Version-Release number of selected component (if applicable):
rawhide 2007-04-17.

How reproducible:
for many fedora versions.

Steps to Reproduce:
1. pxeboot
2. ftp method
3. enter ip details = ipv4 only + dhcp
4. ok

Actual results:
Sits there for about 20 seconds.

Expected results:
Once dhcp server has provided the ip address for the machine, the installer
should immediately continue.

Additional info:
If the only reason for the reverse lookup is to configure the hostname for the
machine, then that could be done further through the install (when the installer
will be ready to use the info), or else run the lookup in a separate thread so
as not to "stall" the installer.

To test you need to ensure the machine has no ip > dns name mapping on the dhcp
supplied dns server.
Comment 1 David Cantrell 2007-04-17 13:39:08 EDT
The loader does continue after getting a lease.  The reason for the reverse
lookup is for your installation source.  If you specify that with a name and we
can't look it up, the DNS timeout applies.

What is listed in the log on tty3 when it gets to this point?  Is it
transferring a stage2 image?
Comment 2 Bug Zapper 2008-04-03 20:07:50 EDT
Based on the date this bug was created, it appears to have been reported
against rawhide during the development of a Fedora release that is no
longer maintained. In order to refocus our efforts as a project we are
flagging all of the open bugs for releases which are no longer
maintained. If this bug remains in NEEDINFO thirty (30) days from now,
we will automatically close it.

If you can reproduce this bug in a maintained Fedora version (7, 8, or
rawhide), please change this bug to the respective version and change
the status to ASSIGNED. (If you're unable to change the bug's version
or status, add a comment to the bug and someone will change it for you.)

Thanks for your help, and we apologize again that we haven't handled
these issues to this point.

The process we're following is outlined here:

We will be following the process here:
http://fedoraproject.org/wiki/BugZappers/HouseKeeping to ensure this
doesn't happen again.
Comment 3 Bug Zapper 2008-05-06 21:30:05 EDT
This bug has been in NEEDINFO for more than 30 days since feedback was
first requested. As a result we are closing it.

If you can reproduce this bug in the future against a maintained Fedora
version please feel free to reopen it against that version.
