Sorry, I forgot to CC, my fault. I'll do it from now on.

Program listening 0.0.0.0:8002 is python

Here is the netstat output:

Proto    Recv-Q    Send-Q    Local Address    Foreign Address    State       PID/Program name   
tcp        0               0             0.0.0.0:8002        0.0.0.0:*                 LISTEN    6416/python
