SYSLOGD(8)

NAME
syslogd - log systems messages

SYNOPSIS
syslogd [-f config_file] [-m mark_interval] [-p log_socket]

DESCRIPTION
Syslogd reads and logs messages to the system console, log files, other machines and/or users as specified by its configuration file. The options are as follows:

-f  Specify the pathname of an alternate configuration file; the default is /etc/syslog.conf.

-m  Select the number of minutes between ``mark'' messages; the default is 20 minutes.

-p  Specify the pathname of an alternate log socket; the default is /dev/log.

Syslogd reads its configuration file when it starts up and whenever it receives a hangup signal. For information on the format of the configuration file, see syslog.conf(5).

Syslogd reads messages from the UNIX domain socket /dev/log, from an Internet domain socket specified in /etc/services, and from the special device /dev/klog (to read kernel messages).

Syslogd creates the file /var/run/syslog.pid, and stores its process id there. This can be used to kill or reconfigure syslogd.

The message sent to syslogd should consist of a single line. The message can contain a priority code, which should be a preceding decimal number in angle braces, for example, ‘<5.>’ This priority code should map into the priorities defined in the include file <sys/syslog.h>.
