correct DISPLAY setting

I am trying to do x-forwarding (not ssh tunneling, which has it own problem for me) with some network computer. Before I do that, I wanted to test what's the correct DISPLAY to set to. So here's the experiment:

DISPLAY=:0.0 xclock
works, but

# xhost && DISPLAY=localhost:0.0 xclock
access control enabled, only authorized clients can connect
Error: Can't open display: localhost:0.0
This obvious implies that if I set DISPLAY=(my ip address):0.0 at another computer, it will fail as well. Any idea?

Yes, that's why I ran xhost, just to show that localhost is already added to the list. Note the line


$ echo $DISPLAY
$ xclock  (xclock runs...quit xclock)
$ xhost +localhost
localhost being added to access control list
$ xhost
access control enabled, only authorized clients can connect
$ DISPLAY=localhost:0 xclock
Error: Can't open display: localhost:0
