[Tutor] Socket connection refused

[Djoumy .]

 Since it's only a small test program there are bugs for sure in my app.
Anyway thanks for your help. If it works under your Linux, can the problem
be coming from my Windows XP ?

Hi there,

I'm also new at python but I copied/pasted your source code and it ran
fine after I'd sorted out the formatting, but I suspect that was because
of my email client.

Anyway it runs on linux ok, the only issue I found was that when
connecting, then clicking on the OK button on the 'Hello World' message
I get the following TkDialog up "Can't connect to the server 127.0.0.1
EISCONN"

Sorry I can't be of anymore help.

Cheers
Nick.
