NAME

       syslog.conf - configuration file for syslogd system log daemon

SYNOPSIS

       /etc/syslog.conf

DESCRIPTION

       The  file  /etc/syslog.conf contains information used by the system log daemon, syslogd(1M), to forward a system message to appropriate log
       files and/or users. syslogd preprocesses this file through m4(1) to obtain the correct information for certain log files, defining  LOGHOST
       if the address of "loghost" is the same as one of the addresses of the host that is running syslogd.

       A configuration entry is composed of two TAB-separated fields:

	 selector	action

       The selector field contains a semicolon-separated list of priority specifications of the form:

	 facility.level [ ; facility.level ]

       where  facility	is  a  system facility, or comma-separated list of facilities, and level is an indication of the severity of the condition
       being logged. Recognized values for facility include:

       user	   Messages generated by user processes. This is the default priority for messages from programs or facilities not listed in  this
		   file.

       kern	   Messages generated by the kernel.

       mail	   The mail system.

       daemon	   System daemons, such as in.ftpd(1M)

       auth	   The authorization system: login(1), su(1M), getty(1M), among others.

       lpr	   The line printer spooling system: lpr(1B), lpc(1B), among others.

       news	   Designated for the USENET network news system.

       uucp	   Designated for the UUCP system; it does not currently use the syslog mechanism.

       cron	   Designated for cron/at messages generated by systems that do logging through syslog. The current version of the Solaris Operat-
		   ing Environment does not use this facility for logging.

       audit	   Designated for audit messages generated by systems that audit by means of syslog.

       local0-7    Designated for local use.

       mark	   For timestamp messages produced internally by syslogd.

       *	   An asterisk indicates all facilities except for the mark facility.

       Recognized values for level are (in descending order of severity):

       emerg	  For panic conditions that would normally be broadcast to all users.

       alert	  For conditions that should be corrected immediately, such as a corrupted system database.

       crit	  For warnings about critical conditions, such as hard device errors.

       err	  For other errors.

       warning	  For warning messages.

       notice	  For conditions that are not error conditions, but may require special handling. A configuration entry  with  a  level  value	of
		  notice must appear on a separate line.

       info	  Informational messages.

       debug	  For messages that are normally used only when debugging a program.

       none	  Do not send messages from the indicated facility to the selected file. For example, a selector of

		  *.debug;mail.none

		  sends all messages except mail messages to the selected file.

       For  a  given facility and level, syslogd matches all messages for that level and all higher levels. For example, an entry that specifies a
       level of crit also logs messages at the alert and emerg levels.

       The action field indicates where to forward the message. Values for this field can have one of four forms:

	   o	  A filename, beginning with a leading slash, which indicates that messages specified by the selector are to  be  written  to  the
		  specified  file.  The  file  is  opened in append mode if it exists. If the file does not exist, logging silently fails for this
		  action.

	   o	  The name of a remote host, prefixed with an @, as with: @server, which indicates that messages specified by the selector are	to
		  be  forwarded  to  the syslogd on the named host. The hostname "loghost" is treated, in the default syslog.conf, as the hostname
		  given to the machine that logs syslogd messages. Every machine is "loghost" by default, per the hosts database. It is also  pos-
		  sible  to  specify one machine on a network to be "loghost" by, literally, naming the machine "loghost". If the local machine is
		  designated to be "loghost", then syslogd messages are written to the appropriate files. Otherwise, they are sent to the  machine
		  "loghost" on the network.

	   o	  A  comma-separated  list  of	usernames,  which indicates that messages specified by the selector are to be written to the named
		  users if they are logged in.

	   o	  An asterisk, which indicates that messages specified by the selector are to be written to all logged-in users.

       Blank lines are ignored. Lines for which the first nonwhite character is a '#' are treated as comments.

EXAMPLES

       Example 1 A Sample Configuration File

       With the following configuration file:

       *.notice 		     /var/log/notice
       mail.info		     /var/log/notice
       *.crit			     /var/log/critical
       kern,mark.debug		     /dev/console
       kern.err 		     @server
       *.emerg			     *
       *.alert			     root,operator
       *.alert;auth.warning	     /var/log/auth

       syslogd(1M) logs all mail system messages except debug messages and all notice (or higher) messages into a file named  /var/log/notice.	It
       logs all critical messages into /var/log/critical, and all kernel messages and 20-minute marks onto the system console.

       Kernel messages of err (error) severity or higher are forwarded to the machine named server. Emergency messages are forwarded to all users.
       The users root and operator are informed of any alert messages. All messages from the authorization system of warning level or  higher  are
       logged in the file /var/log/auth.
