.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
utility provides a shell command interface to the
|
|
.Xr syslog 3
|
|
system log module.
|
|
.Pp
|
|
The following options are available:
|
|
.Bl -tag -width indent
|
|
.It Fl 4
|
|
Force
|
|
.Nm
|
|
to use IPv4 addresses only.
|
|
.It Fl 6
|
|
Force
|
|
.Nm
|
|
to use IPv6 addresses only.
|
|
.It Fl A
|
|
By default,
|
|
.Nm
|
|
tries to send the message to only one address,
|
|
even if the host has more than one A or AAAA record.
|
|
If this option is specified,
|
|
.Nm
|
|
tries to send the message to all addresses.
|
|
.It Fl i
|
|
Log the process id of the logger process
|
|
with each line.
|
|
This flag is ignored and the process id is always logged.
|
|
.It Fl s
|
|
Log the message to standard error, as well as the system log.
|
|
.It Fl f Ar file
|
|
Read the contents of the specified file into syslog.
|
|
This option is ignored when a message is also specified.
|
|
.It Fl H Ar hostname
|
|
Set the hostname in the header of the message to specified value.
|
|
If not specified, host part of
|
|
.Xr gethostname 3
|
|
will be used.
|
|
.It Fl h Ar host
|
|
Send the message to the remote system
|
|
.Ar host
|
|
instead of logging it locally.
|
|
Note that
|
|
.Nm
|
|
currently supports
|
|
.Li AF_INET
|
|
.Pq IPv4 ,
|
|
.Li AF_INET6
|
|
.Pq IPv6 ,
|
|
and
|
|
.Li AF_LOCAL
|
|
.Pq Unix-domain socket
|
|
address families.
|
|
The following address formats are valid in
|
|
.Ar host :
|
|
.Pp
|
|
.Bl -tag -width "AF_LOCAL" -compact
|
|
.It Li AF_INET
|
|
192.168.2.1
|
|
.It Li AF_INET6
|
|
2001:db8::1
|
|
.It Li AF_LOCAL
|
|
.Pa /var/run/log
|
|
.El
|
|
.It Fl P Ar port
|
|
Send the message to the specified
|
|
.Ar port
|
|
number on a remote system,
|
|
which can be specified as a service name
|
|
or as a decimal number.
|
|
The default is
|
|
.Dq Li syslog .
|
|
If an unknown service name is used,
|
|
.Nm
|
|
prints a warning and falls back to port 514.
|
|
.It Fl p Ar pri
|
|
Enter the message with the specified priority.
|
|
The priority may be specified numerically or as a
|
|
.Li facility.level
|
|
pair.
|
|
For example,
|
|
.Dq Fl p Li local3.info
|
|
logs the message(s) as
|
|
.Ar info Ns rmational
|
|
level in the
|
|
.Ar local3
|
|
facility.
|
|
The default is
|
|
.Dq Li user.notice .
|
|
.It Fl S Ar addr Ns \&: Ns Ar port
|
|
Specify source address and/or source port when using
|
|
.Fl h
|
|
option.
|
|
The same address will be used for all of the remote addresses
|
|
when
|
|
.Fl A
|
|
flag is enabled.
|
|
Note that a numeric IPv6 address in
|
|
.Ar addr
|
|
must be enclosed with
|
|
.Dq \&[
|
|
and
|
|
.Dq \&] .
|
|
.It Fl t Ar tag
|
|
Mark every line in the log with the specified
|
|
.Ar tag
|
|
rather than the default of current login name.
|
|
.It Ar message
|
|
Write the message to log; if not specified, and the
|
|
.Fl f
|
|
flag is not
|
|
provided, standard input is logged.
