I've had to fight with stuff before but I can usually get it going (arpwatch, mpd, etc.). Now I'm trying to get sntop to run now and I'm getting nowhere.

A few things would help diagnose this problem:
o FreeBSD version
o output with rc_debug=yes in /etc/rc.conf
o the output of: ls -l /usr/local/etc/rc.d
o the contents of the local_startup knob
i.e: grep local_startup /etc/defaults/rc.conf /etc/rc.conf
Also, I'm not sure how up-to-date the handbook is. You should probably
also read rc(8).

Lose the .sh suffix. The only rc.d scripts that should end in .sh are
scripts that need to run from within the parent script. I doubt there's
a need in this case.

Is the above duplication a 'copy&paste' mistake or is it really in
the script? If so, this may be your problem right here.

You can get rid of this line by simply putting
sntop_nice="5"
in /etc/rc.conf.

why perl?

This may mean that the program didn't damonize. If it didn't then obviously
it will terminate when you terminate the terminal you started it from. Do
you get your prompt back after you run this command?
Cheers,
Mike.
