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

     -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 messages.

     -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 sys/syslog.h.


     /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.
