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 UTek 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(3c). The second part of each line describes where the message is to be logged if this line is selected. There are four forms: 1.A filename (beginning with a leading slash). The file will be opened in append mode. 2.A hostname preceded by an at sign ( @ ). Selected messages are forwarded to the syslogd on the named host. 3.A comma separated list of users. Selected messages are written to those users if they are logged in. 4.An asterisk. Printed 5/12/88 1
SYSLOGD(8N) COMMAND REFERENCE SYSLOGD(8N) 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, for example: kill `cat /etc/syslog.pid` FILES /etc/syslog.conf the configuration file /etc/syslog.pid the process id /dev/log the UTek domain datagram log socket /dev/klog the kernel log device CAVEATS The kernel log device is not implemented in the current version of UTek.
