<html><body><div style="color:#000; background-color:#fff; font-family:HelveticaNeue, Helvetica Neue, Helvetica, Arial, Lucida Grande, sans-serif;font-size:12pt">Harvey,<br><br>Thanks for suggesting the "ssh -Y". That works (as done "ssh -X") but unfortunately it doesn't solve my problem. We are trying to drop X2Go into an existing environment as a replacement for a current solution, and can't force a change in how users connect to the remote machines. For X2Go we really need to figure out how to get this working with a simple "xhost +" and "setenv DISPLAY host:display".<br><br>Interestingly, it looks like freenx/opennx work fine in this mode, but we would prefer not to use that solution as it appears to be a dead end. There must be something different about how freenx/opennx set up security vs X2Go, but I can't find much documentation on configuring security in X2Go.<br><br>I'll spend some more time in the man pages, but any other
suggestions here would be greatly appreciated.<br><br>Thanks<br><div style="display: block;" class="yahoo_quoted"> <br> <br> <div style="font-family: HelveticaNeue, Helvetica Neue, Helvetica, Arial, Lucida Grande, sans-serif; font-size: 12pt;"> <div style="font-family: HelveticaNeue, Helvetica Neue, Helvetica, Arial, Lucida Grande, sans-serif; font-size: 12pt;"> <div dir="ltr"> <font face="Arial" size="2"> On Wednesday, December 4, 2013 8:22 PM, Harvey Eneman <harvey.eneman@oracle.com> wrote:<br> </font> </div> <div class="y_msg_container">If you haven't already, I suggest that use "ssh -Y" to setup trusted X11<br clear="none">forwarding when you connect to the remote linux box from a terminal<br clear="none">window (eg. xterm) on the "local" linux host.
