2.6.4.2. 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 are correlated 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/services
file.flags
— Sets any of a number of attributes for the connection.REUSE
instructsxinetd
to reuse the socket for a Telnet connection.Note
TheREUSE
flag is deprecated. All services now implicitly use theREUSE
flag.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_failure
in 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.
