Slinky,

Jun  1 14:11:55 localhost in.tftpd[30132]: RRQ from 192.168.1.2 filename /pxelinux.cfg/default

So, I reread the man page, and it says that filename should be set to "pxelinux.0" and I had "/pxelinux.0", which is what dhcp.template came with

pxelinux.0 is the binary pxe loader. dhcp needs to point at pxelinux.0 (wherever it is*), as this is what the client needs to boot with.

default is the default pxe configuration which a request falls down to if the corresponding 01-aa-bb-cc-dd-ee-ff isn't found, and is generally found in pxelinux.cfg/


* If my dhcp was something like...

if option client-architecture = 00:00 { # Intel x86PC
   option LINUX.pxelinux-magic F1:00:74:7E;
   option LINUX.pxelinux-pathprefix "cobbler";
   option LINUX.pxelinux-reboottime 50;
   filename "cobbler/loader/pxelinux.0";
}
else if option client-architecture = 00:02 { # EFI Itanium
   filename "cobbler/loader/elilo64.0";
}
else if option client-architecture = 00:06 { # EFI IA32 - future extension (think Intel Apple ..)
   filename "cobbler/loader/elilo32.0";
}

A client would expect to find it in /tftpboot/cobbler/loader/pxelinux.0....

Does that help?

 

(Should I file a ticket?).

No.
 

 So I changed that to "pxelinux.0", and attempted to run cobbler sync, which tells me:

[root@localhost ole]# cobbler sync
cannot find directory: -v

I tried restarting the cobbler daemon and doing cobbler sync and the same message appears.  Thoughts?

tbh your cobbler setup sounds a bit FUBAR. Purge and try again perhaps?
 

Thanks again,
- Ole

Make sure you have verbose enabled in /etc/xinetd.d/tftp

You'll then see tftp hits in /var/log/messages. Example:

/var/log/messages.3:May 13 09:12:47 islinky in.tftpd[3556]: RRQ from 137.138.32.49 <http://137.138.32.49> filename tftpboot/dir/file.cbt

It could just be some thing simple like you're dhcp points somewhere but your tftp "files" are else where.

   Any trouble shooting tips?  I used to get a "boot" menu prior to
   adding a system...

   TIA,
