Python sockets are the easiest I've used. However, I think it can be useful
know a little bit more about socket programming than what one normally gets
from a Python or Perl or whatever tutorial. Even reading through some of the
C-based tutorials will help (if not, at least it'll make you grateful you
get to use the
Python socket API rather than the raw C API). I'm not saying you have to
digest Stephens completely, but I've seen aome pretty good intros for linux
programmers. If you can't find one, let me know and I'll dig a little.

Whatever gets the job done. Socket programming is easy and difficult - easy
to get something up and running, difficult to get working perfectly.
> What is the best module to use between socket or asyncore ?
asyncore allows you to avoid threads. I don't know why anyone would want
to avoid threads, especially Python threads.

As I said, I think the C tuts are pretty good (just so you know what's going
under the hood). The socket programming chapters in the 2nd edition of
Programming Python (Lutz) are particularly excellent - I wish I'd had them
years ago. Look in the Google directory for good, oatsy socket stuff. Post
problem sections of your code, or send them and I'll take a look.
