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

     syslogd - log systems messages

     syslogd [-du] [-f config_file] [-m mark_interval] [-a path] [-p

     Syslogd reads and logs messages to the system console, log files, other
     machines and/or users as specified by its configuration file.  The op-
     tions are as follows:

     -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 de-
             fault is 20 minutes.

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

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

     -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 sock-
             ets in /dev/log of various chroot filespaces.

     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 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 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>.

     /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.

     The syslogd command appeared in 4.3BSD.

4.2 Berkeley Distribution        June 6, 1993                                2
