Testing if a port is open or close

Recommended Posts

have you already tried to connect to this port?

do you run a server on the other pc?

If you're at the computer
netstat -a -n | find "LISTENING"
will find all open TCP / UDP ports.

Piping the result through your port number will also work, i.e.

netstat -a -n | find "LISTENING" | find 25
to see all processes bound to port 25 (default SMTP port)

Reading the help file before you post... Not only will it make you look smarter, it will make you smarter.
