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?

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)
