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.
