Network Programming in Python

[diffuser78]

I am a newbie in python. I want to learn and implement a small
networking concept. Please help me. Every help is appreciated.

I have one Linux Box and one Windows PC. I want to have a daemon
running on Windows PC which listens on some specicif port number. I
want to send a TCP/IP or UDP/IP packet from Linux box to Windows PC to
start some application. As Windows PC recieves such a packet from Linux
Box it executes a certain .exe file. I want to implement this concept.

In short I want to remotely send command from Linux to Windows PC to
start a particular application.

Thanks, Every help is appreciated.

Thanks...I will read that up...could you give me some more headstart or
if you any sample code which I can study.

Thanks for your help, every help is appreciated

Really, was that so hard?

Python makes sockets a total breeze. You can write an 80's style HTTP
server in less than a page of code.

both chapters I pointed you to contain examples.

I have Python 2.4.2 on windows and Linux both. I got an import error.
how can we obtain the twisted libraries ?

Untested:

from twisted.internet import protocol, reactor
from twisted.protocols import basic

COMMANDS = {
"xterm": ("/usr/bin/xterm", {"DISPLAY": ":1.0"}),
}

class CommandLauncher(basic.LineReceiver):
def lineReceived(self, line):
try:
cmd, env = COMMANDS[line]
except KeyError:
self.sendLine("error")
else:
reactor.spawnProcess(None, cmd, env=env)
self.sendLine("okay")

f = protocol.ServerFactory()
f.protocol = CommandLauncher
reactor.listenTCP(12345, f)
reactor.run()

You should be able to telnet to this (port 12345) and type in
names of commands for it to run. Of course, xterm isn't a very
good win32 program to run but I couldn't think of a better example.
You could also write a program to send command requests to this
server, instead of using telnet.

But making a *good* 80's style http/socket server is a lot of work.
Better pick one of the high level protocols built on top of it,
to shield you from the gory details of raw socket programming.

Look for "Downloading" under <URL: http://twistedmatrix.com/trac/ >.

I got it ...initially sourceforge page linked all old libraries..later
then got this link to twistedmatrix. Thanks.

Have you checked out Pyro (Python Remote Objects)?

I just realized that you are the author of Pyro. Will it be of any help
to me ??

How will Pyon help my cause ?

A misreading of "Pyro". Pyro <URL: http://pyro.sourceforge.net/ >,
of course, is yet another communications layer, but, as was suggested,
one that might particularly suit Mr. Johnson.

Ah! I think I've always mixed up pyrex and pyro and psco, and
never actually new what Pyro really was. I've got it straight
now (how long I'll keep the three of them striaght in my head
is another question).
