-.SH NAME
-syslogd \- log systems messages
-.SH SYNOPSIS
-.B /etc/syslogd
-[
-.BI \-f configfile
-] [
-.BI \-m markinterval
-] [
-.B \-d
-]
-.SH DESCRIPTION
-.I Syslogd
-reads and logs messages into a set of files
-described by the configuration file
-/etc/syslog.conf.
-Each message is one line.
-A message can contain a priority code,
-marked by a number in angle braces
-at the beginning of the line.
-Priorities are defined in
-.RI < sys/syslog.h >.
-.I Syslogd
-reads from the UNIX domain socket
-.IR /dev/log ,
-from an Internet domain socket specified in
-.IR /etc/services ,
-and from the special device
-.I /dev/klog
-(to read kernel messages).
-.PP
-.I Syslogd
-configures when it starts up
-and whenever it receives a hangup signal.
-Lines in the configuration file have a
-.I selector
-to determine the message priorities to which the line applies
-and an
-.IR action .
-The
-.I action
-field are separated from the selector by one or more tabs.
-.PP
-Selectors are semicolon separated lists of priority specifiers.
-Each priority has a
-.I facility
-describing the part of the system that generated the message,
-a dot,
-and a
-.I level
-indicating the severity of the message.
-Symbolic names may be used.
-An asterisk selects all facilities.
-All messages of the specified level or higher (greater severity)
-are selected.
-More than one facility may be selected using commas to separate them.
-For example:
-.PP
-.ti +5
-*.emerg;mail,daemon.crit
-.PP
-Selects all facilities at the
-.I emerg
-level and the
-.I mail
-and
-.I daemon
-facilities at the
-.I crit
-level.
-.PP
-Known facilities and levels
-recognized by
-.I syslogd
-are those listed in
-.IR syslog (3)
-without the leading ``LOG_''.
-The additional facility
-``mark'' has a message at priority LOG_INFO sent to it every
-20 minutes
-(this may be changed with the
-.B \-m
-flag).
-The ``mark'' facility is not enabled by a facility field containing an asterisk.
-The level ``none'' may be used to disable a particular facility.
-For example,
-.PP
-.ti +5
-*.debug;mail.none
-.PP
-Sends all messages
-.I except
-mail messages to the selected file.
-.PP
-The second part of each line describes where the message is to be logged
-if this line is selected.
-There are four forms:
-.IP \(bu 3n
-A filename (beginning with a leading slash).
-The file will be opened in append mode.
-.IP \(bu 3n
-A hostname preceeded by an at sign (``@'').
-Selected messages are forwarded to the
-.I syslogd
-on the named host.
-.IP \(bu 3n
-A comma separated list of users.
-Selected messages are written (using the Zephyr notification system)
-to those users if they have subscribed to "syslog" class notices with
-instance equal the hostname of the machine that syslogd in running on.
-.IP \(bu 3n
-An asterisk.
-Selected messages are written (using Zephyr) to all users who have subscribed
-to the "syslog" class notices with
-instance equal the hostname of the machine that syslogd in running on.
-(This is the Zephyr equivalent of a wall.)
-.IP \(bu 3n
-An "!" followed comma separated list of local users. The local users
-will be notified by examining /etc/utmp to obtain their terminal and writing
-to it.
-.IP \(bu 3n
-"!*" Will write to the ttys of all users found in /etc/utmp.
-.PP
-Blank lines and lines beginning with `#' are ignored.
-.PP
-For example, the configuration file:
-.PP
-.nf
-.ta 4m +\w'*.alert,auth.warning'u+3
- kern,mark.debug /dev/console
- *.notice;mail.info /usr/spool/adm/syslog
- *.crit /usr/adm/critical
- kern.err @ucbarpa
- *.emerg *
- *.alert eric,kridle
- *.alert;auth.warning ralph
-.fi
-.PP
-logs all kernel messages
-and 20 minute marks onto the system console,
-all notice (or higher) level messages and all mail system messages
-except debug messages
-into the file /usr/spool/adm/syslog,
-and all critical messages
-into /usr/adm/critical;
-kernel messages of error severity or higher are forwarded
-to ucbarpa.
-All users will be informed of any emergency messages,
-the users ``eric'' and ``kridle''
-will be informed of any alert messages,
-and the user ``ralph''
-will be informed of any alert message,
-or any warning message (or higher)
-from the authorization system.
-.PP
-The flags are:
-.TP 0.5i
-.B \-f
-Specify an alternate configuration file.
-.TP
-.B \-m
-Select the number of minutes between mark messages.
-.TP
-.B \-d
-Turn on debugging.
-.PP
-.I Syslogd
-creates the file /etc/syslog.pid, if possible,
-containing a single line with its process id.
-This can be used to kill or reconfigure
-.I syslogd.
-.PP
-To bring
-.I syslogd
-down,
-it should be sent a terminate signal (e.g. kill \`cat /etc/syslog.pid\`).
-.SH FILES
-.ta \w'/etc/syslog.conf 'u
-.nf
-/etc/syslog.conf the configuration file
-/etc/syslog.pid the process id
-/dev/log Name of the UNIX domain datagram log socket
