I forgot to include a comparison against something known.  If I test
against one of my own machines, starting and stopping my webserver, I
get the following, with the server running:

  [tim at bigblack ~]$ nmap  -A -p T:80 rover
  
  Starting Nmap 4.20 ( http://insecure.org ) at 2007-08-15 13:56 CST
  Interesting ports on rover.lan (192.168.1.9):
  PORT   STATE SERVICE VERSION
  80/tcp open  http    Apache httpd 2.0.54 ((Fedora))

Notice that it could identify that I was running Apache.  Versus, the
server not running:

  [tim at bigblack ~]$ nmap  -A -p T:80 rover
  
  Starting Nmap 4.20 ( http://insecure.org ) at 2007-08-15 13:54 CST
  Interesting ports on rover.lan (192.168.1.9):
  PORT   STATE  SERVICE VERSION
  80/tcp closed http

Now, if I'd had some peculiar networking, that allowed a connection
through to something, but not to the webserver, it might be showing
"open" or "filtered" as the state.

NB:
It can take a few seconds for the test to complete, unless it gets an
instant closed response.

Rover is the hostname of the test server.  It's a bit of a dog, so it
got named after one.  ;-)

Using FC 4, 5, 6 & 7, plus CentOS 5.  Today, it's FC7.

Don't send private replies to my address, the mailbox is ignored.
I read messages from the public lists.
