The question's a bit unclear... is your client running on RH 7.2 or
the server? Or both?

Presuming the last option, do:

  ssh -f -X <host> xterm

If you want to have X forwarding on all the time with a given host,
you can set that in your ~/.ssh/config file as so:

Host <host>:
	ForwardX11 yes

Note that you *can* use a wild-card, *, in place of <host>, but
this is strongly discouraged as you should only forward access to
your local X server to trusted hosts, and you should explicitly
state your trust of the host on general principle. Giving a remote
host access to your local X console is effectively giving them root
access to your machine, based on how poorly-design i386 memory
management is.

Note also that the sshd on the server will need to have:

X11Forwarding yes

set in its sshd_config in order for you to be able to do this.
