  try running tcpdump or ethreal or snort, i dont belive 
any of these come with mandrake but you can download them.
they will report all the activity on your network depending
on config...tcpdump is the rawest but quickest way to see
whats going on.
 Also, just maybe, one of the boxes is looking to do a network
boot due to a bios config...thus causing all the pre OS load traffic
