Blinky, Thanks for the reply.

Yes, that is certainly one possibility that I have looked at, but it doesnt
go far enough as a solution.

The main thing that "mimic" does for you is to allow a mibwalk snapshot
taken from all the devices on a network to be "replayed" away from the
original network by a special SNMP agent on a linux machine, and to do this
for large numbers of devices. My problem isnt so much making my linux box
pretend to be multiple linux boxes (which could be done exactly as you
suggest or through setting up multiple address on a NIC and associating
responders with them [as per Peter's suggestion]), but I would like it to
simulate the specific 20+ routers, 20+ switches and 40 web servers, some
hubs and printers from a "laboratory" network so I can develop SNMP software
against that network when I am at home and dont have access to it.

I have been told by collegues that there is a GPL project that does exactly
this, but they cant remember it's name.
