Step 1: Send a ping to the subnet's broadcast address.

Step 2: For each machine that answers, contact its port 161, and see if
you get 'port unreachable'.

Step 3: For each machine that did ping, but doesn't say 'port unreachable',
try talking SNMP to the port.

Step 4: Make sure you've talked to the network/security administrator BEFORE
you do this, so you are not lynched by the admins of machines that have
tripwired port 161 to detect portscans....

In other words, be *VERY* sure that you have management backing before trying
it.  Failing to ask first can be quite a Career Limiting Move....
