[ILUG] Running X on a remote machine

[Conor Daly]

Little problem here.  I want to export my Gnome desktop to another box but
it ain't happening.  I did an "X" on the target box and got an x-server up
with no window manager (that's what I want).  Then I did an "xhost
+192.168.1.3" to permit the source box to connect.  Now, on the source box, 
I did an

export DISPLAY=192.168.1.1:0.0

and then did "startx" but nothing happened.  had a look at the startx
script and found that it does a bunch of things with display itself. tried
hacking that but to no avail.  Something like 

bad option 192.168.1.1:0

startx calls xinit with a few args so I must look at that next.

Looked at that and it's xinit that objects to the "192.168.1.1:0".  

Tried "X :1" to start an x-server on /dev/tty8 which works but when I do a 

gnome-session --display=192.168.1.3:1

It tries to start but objects that there is already a gnome session
running (I'm doing this from within gnome) and won't continue.

Tried again from a console with the following sequence:

export DISPLAY=192.168.1.3:1
X :1 &
xhost +192.168.1.3
gnome-session --display=192.168.1.3:1

and all works (192.168.1.3 is Valkerie) but if I do it across the network,
thus (192.168.1.1 is Hobbiton):

on hobbiton:
export DISPLAY=192.168.1.1:1
X :1 &
xhost +192.168.1.3

on valkerie:
gnome-session --display=192.168.1.1:1

I get "can't connect to valkerie:1 even though I've asked it to connect to
hobbiton.

Further tests, and I'm getting the following error

AUDIT: date: 25560 X: client 1 rejected from IP 192.168.1.3 port 1440

pam stuff yes?  What do I do now?
