48.5.4.2. The /etc/xinetd.d/ Directory
The
/etc/xinetd.d/ directory contains the configuration files for each service managed by xinetd and the names of the files correlate to the service. As with xinetd.conf, this directory is read only when the xinetd service is started. For any changes to take effect, the administrator must restart the xinetd service.
The format of files in the
/etc/xinetd.d/ directory use the same conventions as /etc/xinetd.conf. The primary reason the configuration for each service is stored in a separate file is to make customization easier and less likely to affect other services.
To gain an understanding of how these files are structured, consider the
/etc/xinetd.d/krb5-telnet file:
service telnet
{
flags = REUSE
socket_type = stream
wait = no
user = root
server = /usr/kerberos/sbin/telnetd
log_on_failure += USERID
disable = yes
}
These lines control various aspects of the
telnet service:
service— Specifies the service name, usually one of those listed in the/etc/servicesfile.flags— Sets any of a number of attributes for the connection.REUSEinstructsxinetdto reuse the socket for a Telnet connection.Note
TheREUSEflag is deprecated. All services now implicitly use theREUSEflag.socket_type— Sets the network socket type tostream.wait— Specifies whether the service is single-threaded (yes) or multi-threaded (no).user— Specifies which user ID the process runs under.server— Specifies which binary executable to launch.log_on_failure— Specifies logging parameters forlog_on_failurein addition to those already defined inxinetd.conf.disable— Specifies whether the service is disabled (yes) or enabled (no).
Refer to the
xinetd.conf man page for more information about these options and their usage.
