"Connection refused" has a very precise meaning: it means that in response
to the outbound SYN packet, the remote host returned a RST instead of a
SYN/ACK. This happens when the port in question is closed - nothing
listening - but *not* firewalled. A firewalled port will return nothing at
all, which is generally referred to as "stealthed", and which will
eventually cause the socket initiating the outbound connection to time out.
