syslogd(8N) — UTek W2.3



SYSLOGD(8N)             COMMAND REFERENCE             SYSLOGD(8N)



NAME
     syslogd - log systems messages

SYNOPSIS
     /etc/syslogd [ -fconfigfile ] [ -d ]

DESCRIPTION
     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 <syslog.h>.  Syslogd reads
     from the UNIX domain socket /dev/log, from an Internet
     domain socket specified in /etc/services, and from the
     special device /dev/klog (to read kernel messages).

     Syslogd configures when it starts up and whenever it
     receives a hangup signal.  Lines in the configuration file
     have a selector to determine the message priorities to which
     the line applies and an action.

     Selectors are semicolon separated lists of priority
     specifiers.  Each priority has a facility describing the
     part of the system that generated the message, a dot, and a
     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 are selected.
     More than one facility may be selected using commas to
     separate them.  For example:

          *.emerg   mail,daemon.crit

     Selects all facilities at the emerg level and the mail and
     daemon facilities at the crit level.  Known facilities and
     levels are described in syslog(3).

     The second part of each line describes where the message is
     to be logged if this line is selected.  There are four
     forms:

     •  A filename (beginning with a leading slash).  The file
        will be opened in append mode.

     •  A hostname preceeded by an at sign (``@'').  Selected
        messages are forwarded to the syslogd on the named host.

     •  A comma separated list of users.  Selected messages are
        written to those users if they are logged in.

     •  An asterisk.  Selected messages are written to all
        logged-in users.

     For example, the configuration file:

         kern.debug             /dev/console
         *.notice,mail.info     /usr/spool/adm/syslog
         *.crit                 /usr/adm/critical
         kern.err               @tekecs
         *.emerg                *
         *.alert                steve,maynard
         *.alert,auth.warning   ralph


     logs all kernel messages 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
     tekecs.  All users will be informed of any emergency
     messages, the users "steve" and "maynard" 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.

     The flags are:

     -f   Specify an alternate configuration file.

     -d   Turn on debugging.

     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 syslogd.

     To bring syslogd down, it should be sent a terminate signal
     (e.g. kill `cat /etc/syslog.pid`).

FILES
     /etc/syslog.conf    the configuration file
     /etc/syslog.pid     the process id
     /dev/log            Name of the UNIX domain datagram log socket
     /dev/klog           The kernel log device

CAVEATS
     The kernel log device is not implemented in the current
     version of UTek.
