In the last section, we talked about the relationship between IP and ports. And the port number of the software we are learning so far. (this is an interview question.)

Let's talk about it today, how to quickly find the port number used by a certain program?

Example: fiddle; environment: windows

1: run fiddle

2: open after running: task Manager

3: find the process of the corresponding program and the corresponding PID

Ps: if there is no PID column, you need to set it as follows

Click View-> Select column-- > check PID

4: open cmd, enter: netstat-ano | findstr 6900

Note: as can be seen from the above picture, the port number corresponding to PID:6900; is 8888.

So: the port number of fiddle is 8888

Summary: the above steps are to query the PID of the corresponding program, and then get the port number of the corresponding software.
