How have you set it up in inittab?? I use something
like:

x:5:repawn:/usr/bin/X -broadcast 192.168.0.1

that way, if the X process dies, inittab will restart
it for me.

Yep :-)

I don't see how. DHCP should handle requests to any IP
address. Have you got routing enabled?

lol, no 127.0.0.1 is a *special* IP address which is
reserved only for the local machine. This cannot be
seen outside of the machine your working on, since the
"lo" (loopback device) is present on every machine,
and so is specific.

Just as I was excpecting.

errm.....yes and no. what you could do, is write a
shell wrapper which inittab calls and checks for the
exit status of "/etc/init.d/network status". If it is
"up" then do nothing else, if not start the network
service which in turn starx X on the client via the
-direct command.

Sorry if this is vague. If you mail me off list, I can
help further. Or you can phone me on:
