Hi all; On OS Hardening ( http://wiki.centos.org/HowTos/OS_Protection ) there's a section on "Physical Protection" that includes requiring a single-user mode password. There's four lines that look something like this: echo "Require the root pw when booting into single user mode" >> /etc/inittab echo "~~:S:wait:/sbin/sulogin" >> /etc/inittab echo "Don't allow any nut to kill the server" perl -npe 's/ca::ctrlaltdel:\/sbin\/shutdown/#ca::ctrlaltdel:\/sbin\/shutdown/' -i /etc/inittab It's been awhile since I've messed with the /etc/initab file, but why is "Require the root pw when booting into single user mode" being echoed to /etc/inittab? Is this a typo? (I'm guessing that it is based on the third line, which just echos what is being done to the console to the benefit of whoever is typing it in.) If not, ignore this. I just don't want to hose my /etc/inittab file to find out :) Cheers, Cody Jackson

Is this a typo?Yes, I believe so. The line has been adjusted to read: echo "# Require the root pw when booting into single user mode" >> /etc/inittab Thanks for your critical scrutiny. Alan.
