I would be disturbed if Febora actually needed a firewall by default, as
operating systems with sane defaults don't need firewalls by default
(everyone probably disagrees with me, and I would be interested to know
the counterarguments, as 'personal firewalls' seem like some sort of fad
to me).

You could try `pgrep sshd`, but this would also include any
currently-active SSH connections. A more definitive method on most
hosts to run `telnet localhost ssh` -- if you get 'connection refused'
then the daemon is not running. If it is running, you will get an
answerback (then, escape from telnet by pressing control-[ and
entering 'quit' at the resulting prompt).
