Python Socket Server Question

[j.smith1981]

Hi there,

 

I have been having a go at creating a socket server in Python and I am a bit stuck, here's my code:

# Created by: Jeremy Smith

# Illustration taken from: http://effbot.org/librarybook/socket.htm

## Firstly we import the much needed libs:
import socket
import struct, time

# Now define the port no the clients will need to connect to (need to open this port on any NAT or Software based Firewall):
PORT = 8045; # so will technically be like http://192.168.0.2:8045 if it was a http server!

# Now create the socket and get it listening on that port:
service = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
service.bind(("", PORT))
service.listen(1)

print "Socket has been created and is listening on port: ", PORT


while 1: # while true?
  channel, info = service.accept()
  print "Received a connection from: ", info
  
  # can i just put in literals within the send method?
  
  channel.send()
  channel.close()

 

The problem I am having is understanding what I can put in the send method, can I just send any thing like in PHP you can use to send things like "server is alive or something", which would become something along the lines of:

 

channel.send("server is alive")

 

Or am I thinking about this the wrong way completely?

 

Any help is much appreciated,

Jeremy.
