syslog.conf(5) DG/UX 4.30 syslog.conf(5)
NAME
syslog.conf - configuration file for syslogd system log
daemon
SYNOPSIS
/etc/syslog.conf
DESCRIPTION
The file /etc/syslog.conf contains information used by the
system log daemon, syslogd(8), to forward a system message
to appropriate log files and/or users.
A configuration entry is composed of two TAB-separated
fields:
selector action
The selector field contains a semicolon-separated list of
priority specifications of the form:
facility.level[;facility.level]
where facility is a system facility, or comma-separated list
of facilities, and level is an indication of the severity of
the condition being logged. Recognized values for facility
include:
user Messages generated by user processes. This
is the default priority for messages from
programs or facilities not listed in this
file.
kern Messages generated by the kernel.
mail Reserved for the mail system.
daemon System daemons, such as ftpd(1M).
auth Reserved for the auth system; it does not
currently use the syslog mechanism.
lpr Messages generated by the lpr/lpd line
printer spooling system.
news Reserved for the USENET network news system.
uucp Reserved for the UUCP system; it does not
currently use the syslog mechanism.
cron Reserved for the cron system; it does not
currently use the syslog mechanism.

local0-7 Reserved for local use.
mark For timestamp messages produced internally by
syslogd.
* An asterisk indicates all facilities except
for the mark facility.
Recognized values for level are (in descending order of
severity):
emerg For panic conditions that would normally be
broadcast to all users.
alert For conditions that should be corrected
immediately, such as a corrupted system
database.
crit For warnings about critical conditions, such
as hard device errors.
err For other errors.
warning For warning messages.
notice For conditions that are not error conditions,
but may require special handling.
info Informational messages.
debug For messages that are normally used only when
debugging a program.
none Do not send messages from the indicated
facility to the selected file. For example,
a selector of
*.debug;mail.none
will send all messages except mail messages
to the selected file.
The action field indicates where to forward the message.
Values for this field can have one of four forms:
⊕ A filename, beginning with a leading slash, which
indicates that messages specified by the selector
are to be written to the specified file. The file
will be opened in append mode.
⊕ The name of a remote host, prefixed with an @, as
with: @server, which indicates that messages

specified by the selector are to be forwarded to the
syslogd on the named host.
⊕ A comma-separated list of usernames, which indicates
that messages specified by the selector are to be
written to the named users if they are logged in.
⊕ An asterisk, which indicates that messages specified
by the selector are to be written to all logged-in
users.
Blank lines are ignored. Lines for which the first
nonwhite character is a `#' are treated as comments.
EXAMPLE
With the following configuration file:
*.notice;mail.info /usr/adm/notice
*.crit /usr/adm/critical
kern,mark.debug /dev/console
kern.err @server
*.emerg *
*.alert root,operator
*.alert;auth.warning /usr/adm/auth
syslogd will log all mail system messages except debug
messages and all notice (or higher) messages into a file
named /usr/adm/notice. It logs all critical messages into
/usr/adm/critical, and all kernel messages and 20-minute
marks onto the system console.
Kernel messages of err (error) severity or higher are
forwarded to the machine named server. Emergency messages
are forwarded to all users. The users root and operator are
informed of any alert messages. All messages from the
authorization system of warning level or higher are logged
in the file /usr/adm/auth.
