3. Paranoia
After installation, ps auxw’d to check for running services that I didn’t need. I saw inetd and lpd running, so I did the following to turn these services off (without uninstalling their software):
/etc/init.d/inetd stop
/etc/init.d/lpd stop
/usr/sbin/update-rc.d -f inetd remove
/usr/sbin/update-rc.d -f lpd remove
