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

NAME
     syslogd — log systems messages

SYNOPSIS
     syslogd [-V] [-a socket] [-d] [-f config_file] [-h] [-l host_list]
	     [-m mark_interval] [-n] [-p log_socket] [-r] [-s domain_list]
	     [--no-klog] [--no-unixaf] [--no-forward]

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:

     -V	     Print version number and exit.

     --help  Display help information and exit.

     -d	     Enter debug mode. syslogd does not put itself in the background,
	     does not fork and shows debug information.

     -a	     Specify additional sockets from that syslogd has to listen to.
	     This is needed if you are going to let some daemon run within a
	     chroot()'ed environment. You can specify up to 19 additional
	     sockets.

     -f, --rcfile=FILE
	     Specify the pathname of an alternate configuration file; the
	     default is system specific and displayed in the help output.

     -h, --hop
	     Enable forwarding remote messages. By default syslogd will not
	     forward messages it receives from remote hosts.

     -l	     A colon-seperated lists of hosts which should be considered
	     local; they are logged by their hostnames instead by their FQDN.

     -m, --mark=INTERVAL/fP
	     Select the number of minutes between ``mark'' messages; the
	     default is 20 minutes. Setting it to 0 disables timestamps.

     -n, --no-detach
	     Suppress backgrounding and detachment of the daemon from its con‐
	     trolling terminal.

     -p, --socket=PATH
	     Specify the pathname of an alternate log socket.  The default is
	     systemspecific and displayed in the help output.

     -r, --inet
	     Enable to receive remote messages using an internet domain
	     socket.  The default is to not receive any messages from the net‐
	     work. Older version always accepted remote messages.

     -s	     A colon-seperated list of domainnames which should be stripped
	     from the FQDNs of hosts when logging.

     --no-klog
	     Do not listen to the kernel log device. This is only supported on
	     systems which define a kernel log device, on all others this is
	     already the default, and the option will be silently ignored.

     --no-unixaf
	     Do not listen to any unix domain socket. This option overrides -p
	     and -a.

     --no-forward
	     Do not forward any messages. This overrides -h.

     Syslogd reads its configuration file when it starts up and whenever it
     receives a hangup signal.	For information on the format of the configu‐
     ration 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⟩.

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