No. As mentioned in my first mail, hostA is set up like a X terminal to start the X server and query for a remote login screen from hostB directly, without local user login to hostA first. This is achieved by adding the following entry in hostA's /etc/inittab:
ok, hostA is an X terminal ... means it's X server is running on hostA, not hostB.
I also have also tried
hostB-> rlogin hostA hostA% xhost
to see which x-hosts are allowed to connect to hostA, but got still the same error message:
unable to open display ""
What does "" mean?
It means, the DISPLAY variable is empty.
I have also thought to set up more security later using ssh. But for testing purposes, especially on a controlled, trusted LAN, I think it is always easier to get things to work first without extra complexity envolved :-)
Actually, ssh means less complexity ... especially since you are using the XDM session control, which makes things a bit more obscure.
