I believe pxelinux.0 will do the same thing regardless. Is the DHCP server Linux too? Can you do a trace to confirm the correct offer is being given and accepted? The process is like so: 1) PXE BIOS sends DHCP request 2) DHCP server replies with IP address, bootfile-name [i.e. "/pxelinux.0"], next-server [i.e. cobbler], (etc.) 3) PXE BIOS sends TFTP GET request for next-server:/bootfile-name 4) PXE BIOS runs bootfile-name (pxelinux.0), which proceeds to download its config file
Can you confirm that: a) the PXE BIOS is accepting the offer you think it is? Sometimes there's a rogue DHCP server. b) the next-server and bootfile-name given are the ones you think they are? If either is wrong, you may be getting a different bootfile than you expect. Sorry if I'm stating the obvious, but your log snips don't include this information. Also, if the config isn't there, does it go down the list - that is, does it try to download: pxelinux.cfg/AC1213C0 pxelinux.cfg/AC1213C pxelinux.cfg/AC1213 pxelinux.cfg/AC121 ... pxelinux.cfg/default ? You should at least end up with the default config (which is a list of Cobbler profiles).

Anyway, the pxelinux.0 file are the same across all of the cobbler servers per an md5sum check. ----- Original Message ----- From: "Mann, Owen" <[email protected]> To: cobbler mailing list <[email protected]> Cc: Sent: Monday, March 26, 2012 3:49 PM Subject: Re: [cobbler] Problem with PXE when DHCP not running on cobbler server It sounds like the problem is with the pxelinux.0 bootfile - that's what makes the TFTP requests. Is the file your DHCP server is giving out the same as one that works? Thanks!

I am unsure why this is but here is the problem. When you create a new server it creates /tftproot/pxelinux.cfg/$MAC_ADDRESS which is fine and works create on my other cobbler systems. But since this one server is not the dhcp server I get a problem where when the kickstarted server requests its configuration it looks for the hex version of the IP address and not the mac address like in the other cobbler server setup. Or example.. from my log Mar 7 13:32:13 servername in.tftpd[22679]: RRQ from 172.18.18.55 filename pxelinux.cfg/AC1213C0 It does not look for the mac address ever. Since cobbler does not make the hex version of the IP in this manner it kicks back an error saying it cannot be found. I fix this by creating a symlink from the mac address to the hex version of the IP... Then it works. This breaks automation for cobbler. Does anyone have any ideas on how to fix this?
