.Dd October 12, 1995 .Dt SYSLOGD 8 .Os BSD 4.2 .Sh NAME .Nm syslogd .Nd log systems messages .Sh SYNOPSIS .Nm syslogd .Op Fl dI .Op Fl f Ar config_file .Op Fl m Ar mark_interval .Op Fl p Ar log_socket .Sh DESCRIPTION .Nm Syslogd reads and logs messages to the system console, log files, other machines and/or users as specified by its configuration file. The options are as follows: l -tag -width Ds t Fl d Put .Nm syslogd into debugging mode. This is probably only of use to developers working on .Nm syslogd . t Fl f Specify the pathname of an alternate configuration file; the default is
a /etc/syslog.conf . t Fl I Do not log messages received in UDP packets. t Fl m Select the number of minutes between ``mark'' messages; the default is 20 minutes. t Fl p Specify the pathname of an alternate log socket; the default is
p .Nm Syslogd 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 .Xr syslog.conf 5 .
p .Nm Syslogd reads messages from the .Tn UNIX domain socket
a /dev/log , from an Internet domain socket specified in
a /etc/services , and from the special device
a /dev/klog (to read kernel messages).
p .Nm Syslogd creates the file
a /var/run/syslog.pid , and stores its process id there. This can be used to kill or reconfigure .Nm syslogd .
p The message sent to .Nm syslogd should consist of a single line. The message can contain a priority code, which should be a preceding decimal number in angle braces, for example, .Sq Aq 5. This priority code should map into the priorities defined in the include file .Aq Pa sys/syslog.h . .Sh FILES l -tag -width /var/run/syslog.pid -compact t Pa /etc/syslog.conf The configuration file. t Pa /var/run/syslog.pid The process id of current .Nm syslogd . t Pa /dev/log Name of the .Tn UNIX domain datagram log socket. t Pa /dev/klog The kernel log device. .El .Sh SEE ALSO .Xr logger 1 , .Xr syslog 3 , .Xr services 5 , .Xr syslog.conf 5 .Sh HISTORY The .Nm command appeared in x 4.3 . .Sh BUGS The ability to log messages received in UDP packets is equivalent to an unauthenticated remote disk-filling service, and should probably be disabled by default. Some sort of .No inter- Ns Nm syslogd authentication mechanism ought to be worked out.
