making an x*.hosts file

The /etc/X0.hosts file is an ASCII text file containing the hostnames of each remote host permitted to access your local server.

If you are running as a stand-alone system, you must have your system’s name in this file.

If you are part of a network, the other system names must be included.

The syntax is as follows:

<host>

<host>

<host>

For example, if you are hpaaaaa, and regularly ran clients on hpccccc, and hpddddd, you would want the following lines.

hpaaaaa hpccccc hpddddd

Note that aliases work as well as hostnames, provided they are valid, that is, commonly known across the network.
