Description of problem:
Update working PXE server from Red Hat 8 to Red Hat 9
Attempt to use PXE
Traces show the PXE daemon receiving multicast messages and ignoring
them. In addition the mtftpd server runs from inetd which means it does not
run until a packet arrives. Since xinetd doesnt know to join the needed
multicast groups the entire thing doesn't work.
In addition the PXE files license explicitly requires we credit Intel and wait
2 seconds each boot. We don't do this.
I've tcpdumped it for ages, straced it and finally gave up. I replaced the
entire shitpile with pxelinux and the pxelinux recommended pxe daemon
and now it seems to be working ok.
We are dropping support for pxe in the RHEL release and will drop it from future
RedHat release. I am writing up documentation on how to use dhcp/pxelinux for
X86 platforms. I am also attempting to document how to do this on other
platforms IPF and hammer.
