It depends on what your machines are connected to. If they are
connected to a switch, and your snort box is also connected to a
switch, then you will need to put the port that your snort box is
plugged into, into a span/mornitor all mode.
If you cannot do such a thing, then you are out of luck, I am afraid.
Your best bet would be to make the snort box into a router/gatway and
add another NIC to it.
If you are plugged into a HUB, then your snort box *should* be seeing
the traffic, and it could be a case where the signature you are trying
to test against is not being matched. Try making something easy,
alert ip <ip_address_of_pc_a> any -> any any (msg: "Test Rule from PC A";)
Replace <ip_address_of_pc_a> with the IP address of machine labeled PC A.
Restart snort .. If you don't see any traffic, then you've got other
issues at hand (i.e., is snort listening on the right interface?)
