[syslinux] pxelinux - how to direct client to find source files for pxe loading

[Pika Fletcher]

I've got a Fedora 13 box that I am using as a pxe server to pxe load
client machines. Using dhcp, tftp, and http I have been able to
succesfully pxe load clients. However I am now trying to serve up
multiple images via a menu, and not having any luck in configuring my
pxelinux.cfg/default file to direct clients to the appropriate source
repositories. I do have the pxelinux.cfg/default file pointing to the
correct vmlinuz and initrd.img.

I'm pretty sure I am just missing the right "append" argument in my
default file to point to the correct source repository for their
selected menu option. I want it so that if a user selects 'ubuntu' off
the menu, their client gets pointed to the ubuntu source file
directory. As it is right now, it always tries to pull the source
files from "http://1.1.1.2/cdserver", which it gets from my
dhcpd.conf. But I am trying to direct the clients to pull the
different source repositories from subdirectories of that (like
http://1.1.1.2/cdserver/ubuntu, or http://1.1.1.2/cdserver/redhat),
and I cant figure out the right way to do that. I have tried arguments
like 'url' 'server' 'source', but no luck!

Thanks for your help!


My dhcpd.conf

filename "pxelinux.0";
}
