Actually, i believe some sort of restricted shell _is_ what is needed
here.
The r in rsh, IIRC, stands for "remote", not "restricted". It's a
(insecure) method of executing commands on a remote host that you have a
shell account on.
bash has a -r option, this may bee what you want.

i definately would _not_ login as root over telnet, unless your su program
uses a one-time-password system of some sort.

ssh is definately the way you'll want to go. You can get it from any
Debian non-US mirror--put "deb ftp://non-us.debian.org/debian-non-US
stable non-US" or "deb ftp://non-us.debian.org/debian-non-US
unstable/non-US main contrib non-free" in your apt sources.list.
Tera Term Pro is a good plan if you have to connect from windoze machines.
You could even set up ftp to allow you to grab it for quick installation
on any computer you get ahold of. You'll need two 'packages', TeraTerm
from <http://hp.vector.co.jp/authors/VA002416/teraterm.html> and the TTSSH
add-on from <http://www.zip.com.au/~roca/ttssh.html>. Also, heed the
warning that you can only use one add-on at a time!
As an interesting side note, TeraTerm even seems to work under Wine!

Very insecure...
