I looked at this, and all the other stuff max mentions on his website 
(www.seedsforchange.org.uk - look under resources for an X terminal / server 
howto). As far as I could see, it was all set up right. It also doesn't work 
with the xdm display manager - the default one is gdm which is a bit more 
complex.

/etc/X11/Xaccess has one line with just a *, and three lines with the ips of 
all the terminals, with nothing following them.

I don't think it's an authentication problem, because as far as I remember, 
when this is the problem there are more packets sent than just a xdmcp query 
followed by an icmp 'connection refused': it's more like query - please 
authenticate - send auth token - auth failed kind of thing. But i may be 
wrong.

I didn't think of it, but trying to run a remote X app from one of the 
terminals on the server's display and vice versa might be a good halfway 
house test to do. I.e. not the full xdmcp thing, just running a single app 
over the network.

Another useful thing to have set up is ssh both ways between the server and 
the terminals, to save running about the building.

That's what I was doing.

I should give taylor a ring and ask when he's about. If you can't get xdmcp 
working quickly, maybe better to move on to something else that you think is 
worth doing.
