Why am I getting the error “connection refused” in Python? (Sockets)

Question

I\'m new to Sockets, please excuse my complete lack of understanding.

I have a server script(server.py):

#!/usr/bin/python

import socket #import t         


        

Answer 1

host = socket.gethostname()  # Get the local machine name
port = 12397                 # Reserve a port for your service
s.bind((host,port))          # Bind to the port

I think this error may related to the DNS resolution. This sentence host = socket.gethostname() get the host name, but if the operating system can not resolve the host name to local address, you would get the error. Linux operating system can modify the /etc/hosts file, add one line in it. It looks like below( 'hostname' is which socket.gethostname() got).

127.0.0.1   hostname
