Can anybody assist me with debugging what I am doing wrong in this case?
I am running the X2Go client in Window 7 and the X2Go server on a RedHat 6 machine. I would like to have a remote linux host export the display back to the X2Go server, which would then forward it to the Windows 7 client.
Starting a new X2Go session, this works on the local host:
[user@localmachine ~]$ echo $DISPLAY
:84
[user@localmachine ~]$ xhost +
access control disabled, clients can connect from any host
[user@localmachine ~]$ xclock
# note - the xclock starts without problems
But on a remote host, I found I could not connect to that display, even with "xhost +" already set:
[user@remotemachine ~]$ setenv DISPLAY localmachine:84
[user@remotemachine ~]$
xclock
Error: Can't open display: localmachine:84
[user@remotemachine ~]$
As an experiment, I tried setting the DISPLAY on localmachine to use the hostname, after which it could not connect to the display:
user@localmachine ~]$ setenv DISPLAY localmachine:84
[user@localmachine ~]$ xclock
Error: Can't open display: localmachine:84
[user@localmachine ~]$ xhost
xhost: unable to open display "localmachine:84"
I'm probably missing something obvious, but don't have any idea what is misconfigured.
Thanks!
