getting data from a port in use

[Dana Marcusanu]

Yes. I want to write a very small web sniffer that gets data from a
specified port. I already looked at some of the existing ones on Internet,
but they are not in Python (I am trying to learn Python!) and they have a
lot more features that I want. Thanks for your suggestion. I will check
out pcap library.

What do you mean "in use"? You mean you want to evesdropt on
data that's being sent to an existing connection?  If so,
you'll need to use something like the pcap library.

No matter what you're trying to do, this isn't right.  Once the
connection has been accepted, you have to read data from the
socket returned by the accept() call.
