Python: Penetration Testing for Developers

Moving on to the practical

First, we will make a server-side program that offers a connection to the client and sends a message to the client. Run server1.py:

import socket
host = "192.168.0.1" #Server address
port = 12345  #Port of Server
s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
s.bind((host,port)) #bind server 
s.listen(2) 
conn, addr = s.accept()  
print addr, "Now Connected"
conn.send("Thank you for connecting")
conn.close()

The preceding code is very simple; it is minimal code on the server side.

First, import the socket module and define the host and port number: 192.168.0.1 is the server's IP address. Socket.AF_INET defines the IPv4 protocol's family. Socket.SOCK_STREAM defines the TCP connection. The s.bind((host,port)) statement ...
