Hi

Since I am not familiar with the output of tcpdump, I thought I would
post a tcpdump file for review.  Please let me know if you see anything
that might indicate the issue.

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?

Weird indeed.  I should have posted another dump after my last check in.
It resolved some of the issues.

What is the command to compile all network drivers into one file? I want to
create a floppy disk that tries all the drivers. Thanks in advance.
