     syslogd — log systems messages


     syslogd [options ...]


     syslogd reads and logs messages to the system console, log files, other machines and/or
     users as specified by its configuration file.


     -4, --ipv4
             Restrict to IPv4 transport (default).

     -6, --ipv6
             Restrict to IPv6 transport.

             Allow transport with IPv4 and IPv6.

     -a socket
             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.

     -b, --bind addr
             Bind listener to this address/name.

     -B, --bind-port port
             Bind listener to this port.

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

     -D, --rcdir dir
             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 host_list
             A colon-seperated lists of hosts which should be considered local; they are logged
             by their hostnames instead by their FQDN.

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

     -m, --mark interval
             Select the number of minutes between "mark" messages; the default is 20 minutes.
             Setting it to 0 disables timestamps.

     -p, --socket path
             Specify the pathname of an alternate log socket.  The default is system specific 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

     -T, --local-time
             Set local time on received messages.

     -S, --sync
             Force a file sync on every line.

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

             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.

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

     -?, --help
             Display help information and exit.

             Display a short usage message and exit.

     -V, --version
             Print version number and exit.

     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 /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


                      The configuration file.
     /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.
