Default Booting Hangs on "Trying to Load: pxelinux.cfg/default"

Slinky,

Awesome - I get lots of information now, such as:

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 (Should I file a ticket?). 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?

Thanks again,
- Ole

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

(1, File not found) to 137.138.32.49 <http://137.138.32.49>


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,

Default Booting Hangs on "Trying to Load: pxelinux.cfg/default"

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/


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

Does that help?


I think so. Just want to make sure I'm clear. The file is currently here:

[root@localhost ole]# ls /tftpboot/
elilo-3.6-ia64.efi images menu.c32 pxelinux.0 pxelinux.cfg

So if I put "pxelinux.0" for the filename option it should resolve correctly right?




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?


I'll try to nuke the system and profile I added to see whether that caused the hiccup. It was syncing fine before that. Otherwise I'll start from scratch.

Thanks!
- Ole

Regarding your other post about server locations, here's your problem,
Mr. Slinky broke you


-s /tftpboot -vvv

You just set directory explicitly to "-v"




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

lies! LIES!!*


* based on the fact it works for us


That may be, but if so, it's likely tftpd noting the directory arguments
are junk and defaulting to /tftpboot


-s Change root directory on startup. This means the remote host
does not need to pass along the directory as part of the
trans-
fer, and may add security. When -s is specified,
exactly one
directory should be specified on the command line. The
use of
this option is recommended for security as well as
compatibility
with some boot ROMs which cannot be easily made to
include a

directory name in its request.
