Log system messages
|You must be root to run this daemon.|
syslogd [-f config_file] [-m mark_interval] [-t threads]
The syslogd daemon reads and logs messages to the system console, log files, and other machines as specified by its configuration file.
The daemon reads its configuration file when it starts up and whenever it receives a hangup signal. For information on the format of the configuration file, see /etc/syslog.conf.
The messages sent to syslogd should consist of a single line, which may start with a facility/priority (as defined in <syslog.h>) in angle brackets (e.g. "<5> hello"). If the message doesn't specify a priority, it defaults to LOG_USER|LOG_NOTICE ("<13>").
The syslog() API (and the logger utility, which uses syslog()) sends messages to syslogd by opening and writing to /dev/log.
If a log message is submitted to /dev/log, the entry includes the string nto instead of the local host name. If the log message is submitted via the socket interface, the entry includes the host name. If the message is redirected from another syslogd on another host, the entry includes the host name.
The syslogd daemon requires the following files:
The syslogd daemon also requires the libsocket.so shared library.
logger, /etc/services, /etc/syslog.conf
