       syslog.conf - configuration file for syslogd system log daemon


       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

	 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 facil-
       ity include:

       user	   Messages generated by user processes. This is the default  priority	for  mes-
		   sages 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 mecha-

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

       audit	   Designated for audit messages generated by systems that audit by means of sys-

       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

       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

       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


		  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 spec-
		  ified  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 indi-
		  cates that messages specified by the selector are to be forwarded to	the  sys-
		  logd	on the named host. The hostname "loghost" is treated, in the default sys-
		  log.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.

       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.
