Getting rid of portmap

["Randolph S. Kahle" <RandyKahle@KahleAssociates.com>]

I am converting my firewall machine to a Debian
installation. I am in the process of removing unwanted
services so as to lock down the machine against
intrusions.

I am trying to remove portmap, but this program
does not seem to follow the pattern for other
programs. With other program I simply
"dpkg --purge" them. There is no listing of
portmap ("dpkg --list" does not show portmap)
so this approach does not work.

Next I looked at removing the symbolic
link from /etc/rcS.d to portmap so that it would
not be started. Upon reading the documentation
for the update-rc.d script, it seems that this
is the next best approach. However, to do this,
I have to use the '-f' or "force" flag. I am hesitating
to do this until I get some feedback from the
community.

Question --> what is the best approach to stop
portmap from running on a Debian system?

Thanks!
