I've just tried it for you:
gave me a netstat report that refreshed every 10 seconds; is this not working for you?
As for scrolling, are you on NT/2k or a 'home' Windows platform? If you're on NT then just change the properties and add a scrollbar by increasing the screen buffer height.
Anyway, for netstat the format is
Proto - this is the protocol, so TCP or whatever
Local Addresss - this is your machine:port number
Foreign Address - the remote machine:port number
State - if its opening the connection, listening on it, closing it or if its ESTABLISHED. So you just need the bit before the colon in the Foreign Address column.
edit - sorry, I forgot to explain that 'listening' means the port is open and actively waiting to see if someone wants to connect to it. [Edited last by Iain Lambert on August 16, 2001 at 10:45 AM]
