simple chat server

[Burakk]

Hi,

I am using ubuntu lucid and i have started to learn python(vrs 3.1). I
am trying to make a tutorial code(see below) work but when i run the
code, open a terminal window and connect as client with telnet and
type somethings and hit enter, give me error below...(the terminal
says connection closed by foreign host)

if someone can help i will be glad...

thanx

Thank you for your replies...

I have overriden the error handlers
and the results:

Traceback (most recent call last):
  File "/home/burak/NetBeansProjects/intantMarkup/src/
02basicServer.py", line 65, in 
try: asyncore.loop()
  File "/usr/lib/python3.1/asyncore.py", line 206, in loop

self.handle_read()
  File "/usr/lib/python3.1/asynchat.py", line 170, in handle_read
index = self.ac_in_buffer.find(terminator)
TypeError: expected an object with the buffer interface


 But i want to add that i am writing the code in netbeans with python
3.1 and running the code from the programme.. Ubuntu deafult python is
2.6.5. Is this a problem. And i also want to add that i made the .py
executable and run that from terminal too with the same
results...
