YM Scanner

I wrote a small vb program, to detect who is online using Yahoo Messenger. The idea is quite simple, detect open port 5101 tcp - yahoo server, then i returns true. Might help network administrator to detect whose chatting in the network.

while ip x.x.x.0 to x.x.x.255
if port == 5101 then
msg = online

continue loop
end if

Input your ip range
