Python server “Only one usage of each socket address is normally permitted”

Question

I\'m trying to create a very basic server in python that listens in on a port, creates a TCP connection when a client tries to connect, receives data, sends something back,

Answer 1

On Windows, you can try these steps:

1. check which process uses the port.

# 4444 is your port number
netstat -ano|findstr 4444

you will get something like this:

# 19088 is the PID of the process
TCP    0.0.0.0:4444           *:*                                    19088

2. kill this process

With:

tskill 19088

Or:

taskkill /F /PID 19088

Good luck.
