SYSLOGD(8)		 BSD System Manager's Manual		    SYSLOGD(8)

NAME
     syslogd - log systems messages

SYNOPSIS
     syslogd [-dnu] [-a path] [-f config_file] [-m mark_interval]
	     [-p log_socket] [-s reporting_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:

     -a path
	     Specify a location where syslogd should place an additional log
	     socket. Up to about 20 additional logging sockets can be speci-
	     fied. The primary use for this is to place additional log sockets
	     in /dev/log of various chroot filespaces.

     -d	     Enable debugging to the standard output, and do not disassociate
	     from the controlling terminal.

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

     -m mark_interval
	     Select the number of minutes between "mark" messages; the default
	     is 20 minutes.

     -n	     Print source addresses numerically rather than symbolically. This
	     saves an address-to-name lookup for each incoming message, which
	     can be useful when combined with the -u option on a loghost with
	     no DNS cache. Messages from the local host will still be logged
	     with the symbolic local host name.

     -p log_socket
	     Specify the pathname of an alternate log socket to be used in-
	     stead; the default is /dev/log.

     -s reporting_socket
	     Specify path to an AF_LOCAL socket for use in reporting logs
	     stored in memory buffers using syslogc(8).

     -u	     Select the historical "insecure" mode, in which syslogd will ac-
	     cept input from the UDP port. Some software wants this, but you
	     can be subjected to a variety of attacks over the network, in-
	     cluding attackers remotely filling logs.

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

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

     syslogd opens an Internet domain socket as specified in /etc/services.
     Normally syslogd will only use this socket to send messages outwards, but
     in "insecure" mode it will also read messages from this socket. syslogd
     also opens and reads messages from the UNIX domain socket /dev/log, and
     from the special device /dev/klog (to read kernel messages).

     syslogd opens the above described socket whether or not it is running in
     secure mode. If syslogd is running in secure mode, all incoming data on
     this socket is discarded. The socket is required for sending forwarded
     messages.

     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>.

FILES
     /etc/syslog.conf	  configuration file
     /var/run/syslog.pid  process ID of current syslogd
     /dev/log		  name of the UNIX domain datagram log socket
     /dev/klog		  kernel log device
