Python: Connect via LAN?

Question

Just a preface to this question: I have no clue what I am doing, so please excuse any stupidity.

I am making a socket based chatroom that I want to use on a local network (My dad's computer and mine connected through the same wifi).

Here is the server code:

import socket
import sys
# Create a TCP/IP socket
sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
server_address = ('localhost', 10000)
print >>sys.stderr, 'starting up on %s port %s' % server_address
sock.bind(server_address)
sock.listen(1)
while True:
 # Find connections
 connection, client_address = sock.accept()
 try:
 data = connection.recv(999)
 print data
 except:
 connection.close()

Here is the client:

import socket
import sys
# Create a TCP/IP socket
sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
server_address = ('localhost', 10000)
print >>sys.stderr, 'connecting to %s port %s' % server_address
while True:
 try:
 sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
 sock.connect(server_address)
 message=raw_input('Message: ')
 if message=='quit':
 break
 sock.sendall(message)
 except:
 break
sock.close()

When I run the client on one computer, and the server on the other.. the connection isn't made. I believe it is because of server_address = ('localhost', 10000) but I am not sure.. any suggestions?

• Sam Tubb: How do I find that? ipconfig? And where do a put each?
• Victor Castillo Torres: ipconfig or ifconfig in linux, and you have tu put your ip in the server code ¨server_address = ('myip', 10000)¨ and you have to put a client in the computer of your dad and in the client you have to put this ¨server_address = ('myip', 10000)¨
• Sam Tubb: Ok, got it. I'll let you know how it goes.
• aIKid: @VictorCastilloTorres Add that as an answer.
• Victor Castillo Torres: @aIKid Sure, wait a minute :)

Answer 1

You have to use your local ip's for example if you are going to be the server you have to use your own ip in the server code:

to find the ip:

ipconfig - Windows CMD
ifconfig - Linux Shell, Mac Terminal

after you know your ip you have to replace localhost with your own ip:

Server code:

server_address = ('myip', 10000)

so in your father's computer you have to connect to your server:

Client Code:

server_address = ('myip', 10000)
