chroot vs rsh(restricted shell)

[sreenath sarikonda <sreeredhat () yahoo com>]

Hi Everyone,

I am jr SysAdmin. I was asked to setup users such that
when they 
telnet and login they should not be able to browse any
other 
directories 
other than home directories.And also have limited
access to commands. 
Implementing restricted shell(usr/lib/rsh) is pretty
easy. But setting 
up 
chroot with telnet login is a bit difficult.We need to
run a setuid 
script to run the chroot command when a user logs in.
I am a newbie. I 
read 
that having setuid programs is insecure. So please
suggest me which is 
more secure . rsh or chroot.

Thank you
Sreenath.
