I must be lazy these days. Usually I'm only recursive when I make a self reference.

There is no such thing as a perfectly secure computer, unless it is switched
off, melted down, encased in concrete, then tossed into a deep ocean trench.
Even then, someone may work out how to manipulate gravity waves to get at it.
Never assume any security measure covers all future possibilities, as this will
result in great embarrassment at some point in the future. Anyone who offers a
100% security guarentee is either a fraud or a fool.

however, there are things that you can limit... make sure taht ALL services are OFF... (netstat -an should come up almost totally empty). recompile lilo so that it won't listen for any type of break prior to loading the kernel. in fact, you could shut off terminals completly and rely on a firewall protected, ssh listening on a high port running as non-root... you would be smart to limit access to the box on every port (ipchains or iptables will be helpfull for this)...

my suggestion is the above quote though...
