The way to diagnose this better is to do:
tcsh% telnet localhost 7781
See if something is monitoring it. I am guessing you will get a hang or a
"connection refused".
If you get a banner indicating a connection, you should try
typing:
GET /something.txt HTTP/1.0
(Hit return twice). If MV is monitoring this, you should get a
404-style error message. If you get anything else, something else
occupies the port.
Based on what you have said, I am guessing you will get a hang
which says that something is blocking the port, i.e. a firewall
or port-scan interceptor.
