Allowing X11 forwarding is Red Hat's default configuration.  Unless 
you've changed something, it should be fine.

xauth is in everyone's path, as long as it's installed.  If you did a 
"base" install, then it's not.  Log in to the Linux system and type:

which xauth

If it gives you a path, then that's also fine.  At that point, you 
should also be able to:

echo $DISPLAY

The system should then print "localhost:10.0" or something similar.  If 
not, then make sure you configured putty to request X11 forwarding.

Yes, if you want to run an X11 session from a remote location, you'll 
need an X11 server at the remote location.  Several Free Software X11 
servers are available, including Cygwin:
