4 X Server configuration details
This chapter discusses several details concerning the configuration of X hosts, 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 that aliases work as well as hostnames, provided they are valid, that is, commonly
known across the network.
using an /etc/hosts file
This file need not be present if your system is configured to query a nameserver.
The /etc/hosts file is an ASCII text file containing a list of all the host names and internet
addresses known to your system, including your own system.
If your system is not connected to a network, use the loopback address (127.0.0.1) and
the hostname unknown: 127.0.0.1 unknown
For a local system to access a remote host:
• The address and hostname of the remote host must be listed in the local system’s
/etc/hosts file.
• The user must have a valid login (username and password) and home directory
on the remote host.
