Chapter 4: X Windows Configuration Details
This chapter discusses several details concerning the configuration of X hosts, colormaps, mouse, and
keyboard.
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: Aliases work as well as hostnames, provided they are valid, that is, commonly known across the
network.

X0.hosts and X0screens Relation
The default screen configuration file X0screens uses the default X11 remote host file X0.hosts.
Each custom X*screens file is associated with a special X*.hosts file. The number represented by the
"*" causes the correct screen and host files to be used together. For example, X3screens takes an
X3.hosts file. Both are referenced by the server when it is started with a /usr/bin/X11/X :3 command.
If you use a special X*screens file, you need to set your DISPLAY variable appropriately. For the
previous example, it would be set to hostname:3.0.
