I'm running Inzider right now under nt4ws sp6. It can do tcp and udp.
I see it reporting several ports even as high as 50505 tcp. From what
I heard about it is that it uses a spying .dll that tries to watch
winsock usage but some programs don't work with it. It has detected
such things as sygate, netmeeting, I believe all the ports that
NukeNabber is watching (including several udp) but doesn't notice
programs like mirc or services.

Netbus1 uses 12345tcp, netbus2pro usually is 20034tcp. BO1 does use
31337udp.

"When I tested it, my conclusion was that inzider looks for open
UDP ports and not TCP ports. The ports he mentioned (135, 139) are
UDP whereas I believe Netbus and BO use TCP ports."

I don't know about Netbus, but BO uses UDP ports. So if inzider
really does look for only UDP ports and it didn't pick up BO it's
likely that it doesn't scan higher than, say, 10000 or something.
Most scanners or diagnostics tools don't go that high simply
because it would take a while, and normally BO is put on 31337 or
some other equally high number. I would say try putting BO on a low
port number to find out. Since I don't know much about Netbus, it's
just a guess that the same thing is happening, but I really am not
sure since I don't even know which protocol Netbus uses.
