51The options are as follows:
52.Bl -tag -width Ds
53.It Fl d
54Put
55.Nm syslogd
56into debugging mode. 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 listen for log message from remote machines.
64.It Fl m
65Select the number of minutes between ``mark'' messages;
66the default is 20 minutes.
67.It Fl p
68Specify the pathname of an alternate log socket;
69the default is
70.Pa /var/run/log .
71.El
72.Pp
73.Nm Syslogd
74reads its configuration file when it starts up and whenever it
75receives a hangup signal.
76For information on the format of the configuration file,
77see
78.Xr syslog.conf 5 .
79.Pp
80.Nm Syslogd
81reads messages from the
82.Tn UNIX
83domain socket
84.Pa /var/run/log ,
85from an Internet domain socket specified in
86.Pa /etc/services ,
87and from the special device
88.Pa /dev/klog
89(to read kernel messages).
90.Pp
91.Nm Syslogd
92creates the file
93.Pa /var/run/syslog.pid ,
94and stores its process
95id there.
96This can be used to kill or reconfigure
97.Nm syslogd .
98.Pp
99The message sent to
100.Nm syslogd
101should consist of a single line.
102The message can contain a priority code, which should be a preceding
103decimal number in angle braces, for example,
104.Sq Aq 5.
105This priority code should map into the priorities defined in the
106include file
107.Aq Pa sys/syslog.h .
