Testing my Linux system, I ran into a few things
I thought you should know.

Recent Linux kernels do not allow access to environment
strings via ps, except for the user him/herself.
That is, /proc/*/environ is protected 400.  This
could confuse people reading your instructions,
since they would see environments for their own
process but not root's.  To verify environment
strings of login, you need to run ps as root.

It took me a while to reproduce the problem on my
machine, since I didn't look closely enough at
the output of ldd, and I made /etc/libc.so instead
of /etc/libc.so.4 .

Onward to fix my telnetd 8-) .
