48.5.4. xinetd Configuration Files
The configuration files for
xinetd are as follows:
/etc/xinetd.conf— The globalxinetdconfiguration file./etc/xinetd.d/— The directory containing all service-specific files.
48.5.4.1. The /etc/xinetd.conf File
The
/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
These lines control the following aspects of
xinetd:
instances— Specifies the maximum number of simultaneous requests thatxinetdcan process.log_type— Configuresxinetdto use theauthprivlog facility, which writes log entries to the/var/log/securefile. Adding a directive such asFILE /var/log/xinetdlogwould create a custom log file calledxinetdlogin the/var/log/directory.log_on_success— Configuresxinetdto 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— Configuresxinetdto log failed connection attempts or if the connection was denied.cps— Configuresxinetdto 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 48.5.4.2, “The /etc/xinetd.d/ Directory” for more information.
Note
Often, both the
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 48.5.4.3.1, “Logging Options” for further information.
