Open ports from the command prompt CMD console using netsh and netstat

A good way to check what ports your server/computer are listening to is to use the netsh and netstat command(s).


From the command prompt:

To Check What Ports You Computer Is Listening On (Open Ports):

netstat -an |find /i "listening"


To Open A Port Manually From the Command:

netsh -c firewall (hit enter)

set portopening tcp 21 (the protocol and port number can vary to meet your needs).
