Hmm. You have a strange /etc/services file.  You have a service named wizard?

Taking this snippet, it looks odd.  You have 3 requests for the TFTP seesion,
and compaq keeps arping for sundance.  

So it feels like there someone is loosing UDP packets...

And after you have 3 tftp servers started all kinds of strange things can happen.


What were you looking for in the tcpdump output?
