Communication between remote scripts

[ChrisH]

I have a python script (A) that monitors a process (3rd party) on the
local machine (Windows).

I would like to create a second program on a remote Windows computer
that receives an update from program A periodically (maybe every 10
minutes or so), and tells it everything is running without a problem.

Can anyone recommend a good (and preferably simple) way for two programs
to communicate on a network?

Am I correct in saying that remote objects are not really needed for
this?

Perhaps remote objects are a bit overkill for your specific problem.
But then again, Pyro for instance (pyro.sf.net) essentially removes
the need for any network code in your app, and takes care of various
other nasty things that happen at the network level.
So unless you choose to use Pyro or some other high level API,
you will have to deal with all this yourself-- and that may be
more work than you think...

Thanks for the info. I've actually been looking at Pyro as a possible
solution. In some ways however, it seems a lot more powerful than what I
need for this project.

Could you give a simple example of how a two programs can "talk" to one
another? I don't think I really need RPCs in this case.

Well if you don't want (or need) Pyro or another high-level RPC mechanism,
you have to decide on something else. TCP or UDP socket communication
is an option. See Tim Golden's reply.

The Python source distribution contains some small socket examples
(in Demo/sockets/).
