Enabling and disabling access control
The X server permits remote hosts to use the xhost + command to connect to your system.
Ensure that you specify a host name with the xhost + command,
because it disables access control for the X server. This permits you to grant
access to specific hosts, which eases monitoring for potential attacks to
the X server. To grant access to a specific host, run the xhost command
as follows:
# xhost + hostnameIf you do not specify a host name, access will be granted to all hosts.
For more information about the xhost command, see the Commands Reference
