[Twisted-Python] Problem with Echoserver (TCP), Help!

Hi, I am new to Twisted. I use a Twisted 1.3.0 on MS Windows XP Home
Edition, my python version is 2.3

I try the TCP echoserv.py and echoclient.py example. But the client
always fail with following message:

Unhandled error in Deferred:
Traceback (most recent call last):
File "D:\PYTHON23\Lib\site-packages\twisted\internet\default.py", line
134, in

403, in doConnect
r, w, e = select.select([], [], [self.fileno()], 0.0)
select.error: (10022, '')
What is the matter? Thanks.

Hi,

My experience with Twisted is also limited but let me try to help you.
I tried the same combo as you and it worked well with the following
responses:
receive: Hello, world!
receive: What a fine day it is.
receive: Bye-bye!
connection lost: Connection was closed cleanly.

I am sure you started the server before the client.

Do you have some firewall software installed that prevents the client
from connecting to the server?

Thanks

Thanks. I have disabled my firewall. But still failed.

It is a bit strange that echo server UDP works. Only TCP doesn't.

Regards,
