err, well, yeah, - firewall turned off or port opened - .. I know I
can use netstat -nap to find what ports that i need to open, but
JoeRandom can't do that ..  I didn't suggest turning off the firewall,
I really believe Fedora would never do that .. My question was, are
there any plans for handling such purpose .. because so far, the only
approach that i've seen is to disable the firewall - which is rather
an ugly move ..

because JoeRandom don't know what daemon to turn on, and what daemon
to turn off.. he will turn on whatever daemon the found/install .. and
because binding port > 1024 doesnt need root, who knows what
(malicious) software might be utilizing those high ports ..
