Tried
service iptables stop
and no change.

Now that's a possibility, a very strong possibility, but don't know what 
to do about it.  Fedora ships with lokkit, which I used, and that's 
prolly what I did to block or filter this port. During an earlier 
session, I used lokkit, turned it on, as I wasn't sure if she had 
adequate protection from the outside or not.  Afterward I tried to 
unblock it, to turn firewall off, everything that made sense, then I 
uninstalled the package that apparently originally contained lokkit, 
redhat-config-securitylevel-???, rebooted  the system and still same 
symptoms.  I cannot seem to free up that port.  Cannot ping this machine 
either.  So... ???
