I'm playing with a program on desktop. It's listening on port 5060.

However, I don't have anything sending to this location/host.

If I open my laptop's command line, is there a way to send a simple message to my desktop's ipaddress, on port 5060?

This is basically a simply chat program, for those asking what's going on. I'm sure there's more to understand about ports and sockets. So I'm positive there's some limitations to my simplicity.

This is TCP, right? If UDP, that changes the answer a bit. –  selbie Dec 2 '12 at 7:42

They stopped to install it by default? Curses! –  Matteo Italia Dec 2 '12 at 12:44

There is a netcat for windows (http://joncraton.org/blog/46/netcat-for-windows) Also I think ncat from the nmap project will do what you want.

For this type of testing, you probably want to locate and build the source code of a classic open source tool called netcat.

you can check its port number with this in cmd:

netstat -np | find "port #"

example: netstat -np TCP | find "5060"

Welcome to Superuser this doesn't answer the question of how to send a message over a port, this only explains how to use netstat –  50-3 Nov 14 '13 at 3:23
    
Hello and welcome to superuser.com. Your answer does not answer the posters question but instead explains the use of netstat as @50-3 wrote. The answer fields should be used to answer specific questions with specific solutions. –  Mogget Nov 14 '13 at 7:11
