Description

You want to know the applications that are waiting for an incoming call.

Solution.

You only need to know how to use netstat.

1. Press Windows Key + R, type cmd and press enter.

2. In the command window type netstat –a –b -n, and press enter.

You will see many lines like this:

Active Connections

Proto  Local Address      Foreign Address    State                     PID

TCP     0.0.0.0:5800           0.0.0.0:0                      LISTENING    [WinVNC4.exe]

For example here we have the Vnc server, an application for remote control listening at port 5800.
