Google is listening on port 80.

www.google.com is not listening on port 8000
BUT they're filtering it, so rather than their system sending back a TCP
RESET, it just doesn't respond. Behaviour of Google with telnet:
~/> telnet www.google.com 8000
Trying 209.85.229.147...
[hang]
Behaviour with a system that's not listening on port 8000 AND not filtering
(meaning the TCP stack responds with a TCP RESET) :
~/code.google/kamaelia/trunk/Code/Python/Kamaelia/Examples> telnet 192.168.2.1
8001
Trying 192.168.2.1...
telnet: connect to address 192.168.2.1: Connection refused

66.102.7.99 8000 is not listening on port 8000
(checked, it isn't - and like www.google.com it's also filtering rather than
just resetting)

No idea :)
2 & 3 should result in the same behaviour on your system, and I'm confused as
to why it doesn't at present. I think I need slightly more detail here to
help out fixing whatever is the issue.
