RHEL4? Given that RHEL is now at RHEL 6 and RHEL5 itself is rather long
in the tooth having been released over 4 years ago maybe you ought to
think about upgrading your RHEL systems. One benefit to at least going
to RHEL5 is you can use yum instead of up2date. If you have
subscriptions for RHEL then the upgrade is free.

Maybe you should learn how to use the tools?

Summary : A screen manager that supports multiple logins on one
terminal.
Description :
The screen utility allows you to have multiple logins on just one
terminal. Screen is useful for users who telnet into a machine or are
connected via a dumb terminal, but want to use more than just one
login.
Install the screen package if you need a screen manager that can
support multiple logins on one terminal.
