Hello all -

Hopefully you all can help me out. I am fairly new to Cobbler/PXE booting in 
general. I had an interesting issue show up this morning while doing some 
testing of various kickstart files that I am trying to wrap my head around.

For the past week or so I have been testing various kickstarts on two different 
systems by editing the kickstart, taking the system out of cobbler, and 
re-adding it so it is like new and it rebuilds the system via PXE. It has been 
working like a charm.

Until this morning.. I was working with one system (let's call it sysA) which 
is in a subnet 172.19.10.x. For some reason when this system boots up now it 
gets a DHCP address but then tftp times out and eventually boots from local 
disk instead of reinstalling.

I have another system (let's call it sysB) which is in subnet 172.19.34.x. It 
is still working fine. Both of these systems are being served from the same 
cobbler server which has two NICs, one on each subnet.

There were no changes to the cobbler server (besides changing kickstart 
templates slightly and snippets) or the network recently which is really making 
me confused as to why this has happened?

Any ideas on where I can look?

I have tested tftp commands from sysA (after booting from local disk) to the 
cobbler server which work just fine.

The only things I see in logs that are concerning are in the httpd error_logs:

[Wed Feb 22 08:55:07 2012] [error] possible cheetah template error
[Wed Feb 22 08:58:32 2012] [error] possible cheetah template error
[Wed Feb 22 14:34:03 2012] [error] 
/usr/lib64/python2.6/site-packages/mod_python/importer.py:32: 
DeprecationWarning: the md5 module is deprecated; use hashlib instead
[Wed Feb 22 14:34:03 2012] [error]   import md5

However I have not been able to find much in terms of solutions to these errors.

[root@cobbler ~]# rpm -qa|grep cobbler
cobbler-web-2.0.11-2.el6.noarch
cobbler-2.0.11-2.el6.noarch
[root@cobbler ~]# cat /etc/redhat-release
CentOS release 6.2 (Final)
[root@cobbler ~]#

Any direction and any outputs needed please let me know!

Thanks in advance.

Daniel
