I recommend using the linux hardening "Bastille" project's software. As
LinuxPPC/2000 and YellowDog are redhat derivatives I wasn't surprised to
find that there weren't any major issues with my YDL 1.2 workstation.

One issue: Bastille uses perl's Curses extensions. You will want to ensure
that the Curses extension for perl is installed and used by Bastille. This
requires the removal of the Curses support that Bastille provides with
its installation. This is because the Curses support Bastille includes is
specific to the x86 platform.

After that, Bastille worked great for me on my YDL 1.2 workstation.

PS: "perl -mCPAN -e shell" is an easy way to extend perl's capabilities.

PPS: Curses's button widgets looked weird but did work.
