I'm guessing the orignal poster is trying to make the most "userfriendly"
configuration that he can. Requiring a DHCP, BOOTP, or RARP server that
one has administrative access of is, sadly, too complicated for some,
especially those in the Winodows 9X world. I too have seen thos network
cameras that just ask you to hardcode and ARP entry (which you actually
can do on Windows, believe it or not) and ping it. The camera can do the
rest.
tcpdump is prolly the quickest solution, although a custom app that can
sniff the network is probably better. In either case, it's worth seeing
if you can get them to work without having to assign an IP addresses,
even a dummy one, to an interface. (I.e., just do "ifconfig eth0 up"
without assigning an IP. Hopefully tcpdump or whatever sniffer you use
can sniff on eth0 without it having an IP. Then, just look for your own
MAC address and assign eth0 to whatever IP address is being used on the
packet that you saw your MAC address.)
