Then almost certainly nothing is listening on port 8080. My 20 seconds
of googling suggests trying 30001 and 30002... Have you tried leaving
off the --net-http-port argument? The docs I found suggest that just --
net will give you a webserver on port 8080. But I cannot stress enough
that do not have the software installed :-)

You can find out what is listening where by using "netstat -t -l". Look
for lines that say "LISTEN" and look in the "Local Address" column for
the interface addresses and ports.

Trying to connect to an interface where nothing is listening has
resulted in "connection refused" for about as long as there has been a
TCP/IP protocol :-) Of course, when you tried there may always have
been something listening.
