rhel 6: wanting vnc access without tunnelling

[Alex Troubadour]

Hi,
rhel 6.x, at least the 64-bit version, comes with tigervnc server which seems to 
want you to create an ssh tunnel for you to use vncviewer from a remote box to 
the rhel 6.x server ... at least it works if you do this.  However, I want a 
user to simply be able to connect to the rhel 6.x server, run "vncserver", note 
the desktop number given, open vncviewer on their windows box, set the vnc 
server as <rhel_6_server>:<desktop_number>, and click connect ... i.e. without 
having to do an ssh tunnel.  On rhel 5 and before this worked fine ( at least 
through "vnc-server-4.1.2-14.el5_5.4" ).  Now with rhel 6, red hat uses tigervnc 
( 64 bit version ) .

I know it is more secure as is but it is much more practical for us to allow 
usecure vnc access.  Note users still need to know which desktop number to use 
and their vnc password.

I would appreciate any help anyone can provide.
Thanks
