On a RHEL6 box I just tested doing standard ssh -X or ssh -Y it works the same as it did on RHEL5 (and RHEL4 and HP-UX 11i):<br>
<br>
Open the session to the box as normal user.<br>
Run "echo $DISPLAY" to see what display it set for that user e.g. localhost:10.0<br>
<br>
sudo su -<br>
<br>
After switch to root:<br>
export DISPLAY=<normal user's display> (e.g. export DISPLAY=localhost:10.0)<br>
export XAUTHORITY=<normal user's home directory>/.Xauthority (e.g. export XAUTHORITY=/home/jlightner/.Xauthority).<br></blockquote><div><br>These two line are the keys. Glad you tested this. I didn't have a bare machine available to test. <br>

Run xterm as a test to see if it displays back properly.<br>
<br>
If it works on RHEL6 it should work on CentOS6.<br>
<br>
I tested this both from a Windows XP workstation running Cygwin (X Win) and from a CentOS 5 workstation and it worked to display the Xterm to both of those workstations from the RHEL6 server.<br>
