Let us write a very simple client program which opens a connection to a given port 12345 and given host. This is very simple to create a socket client using Python's socket module function.
The socket.connect(hosname, port ) opens a TCP connection to hostname on the port. Once you have a socket open, you can read from it like any IO object. When done, remember to close it, as you would close a file.
The following code is a very simple client that connects to a given host and port, reads any available data from the socket, and then exits.
#!/usr/bin/python # This is client.py file import socket # Import socket module s = socket.socket() # Create a socket object host = socket.gethostname() # Get local machine name port = 12345 # Reserve a port for your service. s.connect((host, port)) print s.recv(1024) s.close() # Close the socket when done
Now run the server.py (check my previous post) in background and then run above client.py to see the result.
# Following would start a server in background. $ python server.py & # Once server is started run client as follows: $ python client.py
This would produce following result.
Got connection from ('127.0.0.1', 48437) Thank you for connecting
