This is probably only of use to developers working on 57.Nm syslogd . 58.It Fl f 59Specify the pathname of an alternate configuration file; 60the default is 61.Pa /etc/syslog.conf . 62.It Fl s 63Operate in secure mode. Do not open a UDP socket to listen for log message 64from remote machines. 65.It Fl m 66Select the number of minutes between ``mark'' messages; 67the default is 20 minutes. 68.It Fl p 69Specify the pathname of an alternate log socket; 70the default is 71.Pa /dev/log . 72.El 73.Pp 74.Nm Syslogd 75reads its configuration file when it starts up and whenever it 76receives a hangup signal. 77For information on the format of the configuration file, 78see 79.Xr syslog.conf 5 . 80.Pp 81.Nm Syslogd 82reads messages from the 83.Tn UNIX 84domain socket 85.Pa /dev/log , 86from an Internet domain socket specified in 87.Pa /etc/services , 88and from the special device 89.Pa /dev/klog 90(to read kernel messages). 91.Pp 92.Nm Syslogd 93creates the file 94.Pa /var/run/syslog.pid , 95and stores its process 96id there. 97This can be used to kill or reconfigure 98.Nm syslogd . 99.Pp 100The message sent to 101.Nm syslogd 102should consist of a single line. 103The message can contain a priority code, which should be a preceding 104decimal number in angle braces, for example, 105.Sq Aq 5. 106This priority code should map into the priorities defined in the 107include file 108.Aq Pa sys/syslog.h . 109.Sh FILES 110.Bl -tag -width /var/run/syslog.pid -compact 111.It Pa /etc/syslog.conf 112The configuration file. 113.It Pa /var/run/syslog.pid 114The process id of current 115.Nm syslogd . 116.It Pa /dev/log 117Name of the 118.Tn UNIX 119domain datagram log socket. 120.It Pa /dev/klog 121The kernel log device. 122.El 123.Sh SEE ALSO 124.Xr logger 1 , 125.Xr syslog 3 , 126.Xr services 5 , 127.Xr syslog.conf 5 128.Sh HISTORY 129The 130.Nm 131command appeared in 132.Bx 4.3 . 133.Sh BUGS 134The ability to log messages received in UDP packets is equivalent to 135an unauthenticated remote disk-filling service, and should probably be 136disabled by default. Some sort of 137.No inter- Ns Nm syslogd 138authentication mechanism ought to be worked out. 139 140
