Windows Netstat

Windows netstat lets you view open ports, live connections, and what process is listening to a port.

Live Ports

Windows displays open ports and live connections with the netstat –a command. The output looks exactly like that under “Netstat Display Headers” earlier in this chapter.

On even a small laptop, this can generate hundreds of lines of output. I strongly recommend using a pager like more. (You’ll need a modern terminal, not the MS-DOS Command Prompt.)

> netstat –na | more

A list of all open ports and active connections might be complete, but it contains far more than you’re looking for. How do you narrow it down?
