xinetd
are as follows:
/etc/xinetd.conf
— The global xinetd
configuration file.
/etc/xinetd.d/
— The directory containing all service-specific files.
/etc/xinetd.conf
file contains general configuration settings which affect every service under xinetd
's control. It is read when the xinetd
service is first started, so for configuration changes to take effect, you need to restart the xinetd
service. The following is a sample /etc/xinetd.conf
file:
defaults { instances = 60 log_type = SYSLOG authpriv log_on_success = HOST PID log_on_failure = HOST cps = 25 30 } includedir /etc/xinetd.d
xinetd
:
instances
— Specifies the maximum number of simultaneous requests that xinetd
can process.
log_type
— Configures xinetd
to use the authpriv
log facility, which writes log entries to the /var/log/secure
file. Adding a directive such as FILE /var/log/xinetdlog
would create a custom log file called xinetdlog
in the /var/log/
directory.
log_on_success
— Configures xinetd
to log successful connection attempts. By default, the remote host's IP address and the process ID of the server processing the request are recorded.
log_on_failure
— Configures xinetd
to log failed connection attempts or if the connection was denied.
cps
— Configures xinetd
to allow no more than 25 connections per second to any given service. If this limit is exceeded, the service is retired for 30 seconds.
includedir
/etc/xinetd.d/
— Includes options declared in the service-specific configuration files located in the /etc/xinetd.d/
directory. Refer to Section 2.3.4.2, “The /etc/xinetd.d/ Directory” for more information.
log_on_success
and log_on_failure
settings in /etc/xinetd.conf
are further modified in the service-specific configuration files. More information may therefore appear in a given service's log file than the /etc/xinetd.conf
file may indicate. Refer to Section 2.3.4.3.1, “Logging Options” for further information.
