Question About Port Numbers?

Dougal95 · 4 Dec 2009 at 21:37

Hello Folks

Can anyone tell me if there's any software, preferably free :-)

that will show me exactly which applications and services are using what port numbers at any one time?

Many thanks

I think netstat does that, probably the easiest way.

It will yeah, but it's not dynamic and can be a pain to sift through

tcpview is effectively a GUI version of netstat and is much friendlier on the eyes and can be sorted.

Been a while since I needed to use netstat myself so I couldn't remember if it did exactly what the OP wanted.

I'll make a note of tcpview and have a proper look when I get chance.
