Does anyone know of security considerations of setting up a user as a shell
as follows:

set the shell to:
/usr/local/bin/DragonShell

This DragonShell contains the following:
!/bin/sh

telnet -E dragon.acadiau.ca

Basically it is just to allow a user to telnet from the console of a box,
but not to allow them shell access to that same box.
(The -E switch does not allow them to use ^] to get to the telnet> prompt
and try to execute a shell from there.

Also, that sets the shell type to cons25. Does anyone know how to make this
speak vt100? would the soluton be to add some line like
set TERM = "vt100" before the telnet line in that script? Or is it more
complicated than that?

Basically what I am doing is making this a public dumb terminal that will
allow them to log in and use another host.

Any help would be appreciated... Thanks
-Mike
