[Tutor] Socket connection refused

Mon Feb 23 15:20:31 EST 2004

Hi again,

I just downloaded python on the gf's winxp pc and ran your progams on
there. Ran exactly the same as on the linux box :)

Im gonna attach your files in this email for you to run so we can rule
out formatting issues ;)

Just run fserver.py from one dos box and fclient.py from another dos box
and let us know what happens.

Cheers
Nick.
