Has anyone noticed a problem with the TFTP daemon on SLES12SP1? I have an xCAT
server (2.12.4) running this OS, and booting clients fail with TFTP timing out.
tcpdump shows the TFTP daemon trying to connect to the client on port 113/TCP,
which is the ident/auth port. This can succeed when the client is running the
OS, but if the client is attempting to PXE boot, the server appears to just get
no reply, and eventually the client times out.
Replacing the regular tftp server on my xCAT server with the atftpd resolves
the problem.
Is this a known problem, and is there a patch or a recommended workaround? I'm
happy to supply more info on the problem if needed.
Cheers,
Matt
