I'm trying netstat, then ss.  FreeBSD does not support "netstat -n", and
not all distros have gpsd in /etc/services.  So this should catch those:

if [ `which netstat` ]; then
    # FreeBSD does not support "-n"
    netstat -lp | egrep "gpsd|:2947"
elif [ `which ss` ]; then
    ss -lpn | egrep 'gpsd|:2947 '
fi

The "netstat -l", and "ss -l", only shows listening ports, so no IP leakage!

Then Debian changed to conform to the PEPs?

Nothing wrong with that, it is the lack of python that is the problem.

I'm not sure how that means gpsdebuginfo should change?  But that mess
did surface on IRC, again, from anothe confused Debian user.  Which led
to another tweak to the script.

Latest script attached.  It should work on FreeBSD.
