Re: 0.0.0.0?



some really good ideas here (and one scary one), but I think I got 
it figured out. the dchp client made me wonder, since I don't run 
telnetd, ftpd (i do run ssh, but while my system is 3.5, I've 
tried to stay on top of sshd).  

I isolated it to my son's somewhat new iMac.  I just booted it, 
and sure enough a new entry showed up as if on queue.  and the 
first entry coincides with it's arrival to the network.   it's 
got an assigned internal ip, not sure why it would be doing something with 
dchp.  time to revisist the network settings.

it's running os 9.2, perhaps it's time to upgrade to the bsd version :-)

thank you all for the great input
