On the Hobbit server, the client is normally launched by the
hobbitlaunch program running all of the "server" tasks. This is just so
that you won't need to run a hobbitlaunch separately for the server-
and client-side stuff. So in your ~hobbit/server/etc/hobbitlaunch.cfg
you'll probably find a [hobbitclient] section:

	[hobbitclient]
		ENVFILE /usr/lib/hobbit/client/etc/hobbitclient.cfg
		NEEDS hobbitd
		CMD /usr/lib/hobbit/client/bin/hobbitclient.sh
		LOGFILE $BBSERVERLOGS/hobbitclient.log
		INTERVAL 5m

Now - about the "ports" status you have. Your regex is wrong:
   PORT LOCAL=%([.:]22^) STATE=LISTEN "TEXT=SSH listener" color="yellow"
The caret ^ means "beginning of data". You want "end of data", so it should
be a dollar-sign. So that rule should be
   PORT LOCAL=%([.:]22$) STATE=LISTEN "TEXT=SSH listener" color="yellow"

And yes - I know you probably just copied that from the example in the
hobbit-clients.cfg file. I've fixed those now :-)

(In general, for problems with the PCRE regular expressions there is a
utility shipped with the PCRE libraries, "pcretest", which lets you
try out the regular expressions against some data. Quite useful when
you're not a long-time Perl hacker).
