Hi Michael –

 

That helped tremendously.

 

Easily helped me track it down to one line in one of my Snippets causing the issue…. And here I thought it was something on the permission level!

 

All is working fine now, thanks for all the help as simple as it was.

 

Daniel

Try cobbler system getks --name=foo

 

If it's failing to render a kickstart that would explain your Internal Server Error.

Hi –

 

Jorgen:

 

Yes, I do get this on sysB as well but it goes through the install (or did until I hit this latest issue below).

 

All:

 

Well, I am making some progress. Got through the network issue, for whatever reason it appears that commenting out the next_server option in the DHCP template allows it to continue just fine which is good.

 

Now I seem to be running into a permission problem with downloading the kickstart file, and I have not been able to gather a good enough Google search to figure out where to track this down.

 

[root@sys1 ~]# wget http://172.19.10.200/cblr/svc/op/ks/system/sys-dev

--2012-02-22 14:22:13--  http://172.19.10.200/cblr/svc/op/ks/system/sys-dev

Connecting to 172.19.10.200:80... connected.

HTTP request sent, awaiting response... 500 SERVER ERROR

2012-02-22 14:22:13 ERROR 500: SERVER ERROR.

 

This is from a server on the same subnet.

 

Some troubleshooting steps I have done that do not seem to have worked:

 

I looked at the template files to see if anything permission-wise was different. Using one of the standard kickstarts that comes with Cobbler from what I remember work just fine (changed sysB to use a simple profile/default template). I matched up those permissions (in /var/lib/cobbler/kickstarts/) but to no avail.

 

From Apache:

 

172.19.10.10 - - [22/Feb/2012:19:22:13 +0000] "GET /cblr/svc/op/ks/system/sys-dev HTTP/1.0" 500 1595 "-" "Wget/1.12 (linux-gnu)"

 

Apache is running as apache, and all of the files in /var/www/cobbler* are owned by apache:apache. The /var/lib/cobbler* files are owned by root:root.

 

I am still trying to track down what is causing this but I cannot seem to find it so far.

 

All templates/snippets/profiles have only been created/edited in the web UI, never by shell or otherwise.

 

Daniel

Do you get these cheetah template errors from sysB also ???

Google "tftp timeout" and you'll get a lot of hits… there's nothing cobbler specific here, most likely, just network related, and things can be intermittent.

 

Particularly read the timeout info here:  http://fedoraproject.org/wiki/Anaconda/NetworkIssues

 

The portfast issue, in particular, came up a lot.

Hello Siddharth –

 

I tried that and it seems to be working ok!

 

[root@sysA ~]# tftp 172.19.10.200

tftp> get /pxelinux.0

tftp> get /pxelinux.cfg/01-00-00-00-00-00-00

tftp> get //images/CentOS6-x86_64/vmlinuz

tftp> quit

[root@sysA ~]#

 

Not sure if that helps anything or if I should try to get more.

 

[root@sysA ~]# ls -lah

-rw-r--r--   1 root root  15K Feb 22 12:15 pxelinux.0

-rw-r--r--   1 root root    264 Feb 22 12:16 01-00-00-00-00-00-00

[root@sysA ~]# ls -lah|grep vml

-rw-r--r--   1 root root 3.8M Feb 22 12:16 vmlinuz

[root@sysA ~]#

 

Thanks again.

 

Daniel

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.


At the very least, from sysA (or another machine on the same layer-2 network, you should be able to use tftp on the command line and get the pxe boot file from the PXE server. Just in case you haven't tried that already.
