     syslogd — log systems messages


     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]


     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.

             Specify the pathname of an alternate configuration directory; 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 controlling 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 network. Older version always accepted remote

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

             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.

             Do not listen to any unix domain socket. This option overrides -p and -a.

             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 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 one of the special devices /dev/klog or /proc/kmsg
     depending on the system (to read kernel messages). In a GNU/Linux system it will not parse
     the and use it to annotate the kernel messages.

     Syslogd creates the file /var/run/, 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


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

     The syslogd command appeared in 4.3BSD.
