The problem really is that in order to function with Unix, you need read
access to much of the system, and telnet just drops you at a shell, from
which, if you can read it, you can do stuff. removing the execute
permissions from a directory WILL stop you from entering that directory,
but that's a bit extreme.
My suggestion: Why do you allow telnet to them? If you want them to have
access only to limited things, try using a BBS style program which give you
the ability to lock them down.... if you give them access at all. A few
exist...
