Today I was trying to do a XDMCP connection to the other server ( which is solaris, not sure if that matters) so I used the Xnest server. and used the following command:

Xnest :1 -ac -query

And I was getting the error:

AUDIT: Tue Dec 2 20:40:03 2008: 1470 Xnest: client 2 rejected from IP <>

I tried allowing the host to use the display but not use. The command I used was

xhost +

But no use…. I tried searchin using google but found nothing. So I &#8221;read the fine manual&#8221; and found the key I was looking for, to disable all the client access control restrictions:

Xnest :1 -ac -query skyware

And voila. Thought will share this for you all 🙂
[edit] will add more details on what is XDMCP tomorrow.
