question..

Greetings, 
I have few questions regrading permissions on my linux RH4.1.

1.Is it possible that I can stop users from cd to / ..that is when they
  telnet to the server I want then to be restricted to there own home dir.
2. If that is not possible can I disable telnet for certain users ?
3. or chmod to wrx-x-x 711, I think, to all the dirs in the / dir
4. or can I change the / permissions ?without harming the system ?

Thank you in advanced..!
