22, invalid agument error

[Infinite Corridor]

I am trying to get an echoserver running on my N80 Nokia cell phone,
that uses "python for s60".
What worked:
I ran echoclient on the phone and echoserver on my Powerbook and it
worked.

What doesnt work:
When I try running the same scripts, so that I run echoclient on the
laptop and echoserver on the cellphone, the echoserver doesnt work(Yes,
I have changed the IP address correctly).

The error I get is:

File "e:/python/echoserver.py". line
15 in ?
sockobj.bind((' ',40007))
# bind it to server port number
File "<string>", line 1, in bind
error: (22, 'Invalid argument')

Why is this program showing an error on the cellphone when it is
running fine on the Mac?

Thanks, any help will be appreciated.

sockobj.bind((' ',40007))

tried on my N6600 with same error

try using your phone's IP instead of the empty string ''

tried sockobj.bind((' 127.0.0.1',4000 7)) and did not get an error

In general sockets layer bind with null host makes it pick the address
from arp resolution and null in port makes it pick a random number as a
source port. This is reason bind call is not required for client
connections.

I think Python for S60 has some problem in sockets layer for the bind
function. Best is to remove the bind call in the client program as
people will test with this senario in general.

I didn't get an error either, but the whole thing hangs up, and I am
forced to abort the program. This has happend quite a few times
already.
Did it work for you normally?

Well the bind call is in the server program, not the client. I want to
run the server program on the cellphone.
Any idea how to fix it?

Thanks!
