.Sh NAME
|

.Nm rpc.lockd
|
|
.Nd NFS file locking daemon
|
|
.Sh SYNOPSIS
|
|
.Nm
|
|
.Op Fl d Ar debug_level
|
|
.Op Fl g Ar grace period
|
|
.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
utility provides monitored and unmonitored file and record locking services
|
|
in an NFS environment.
|
|
To monitor the status of hosts requesting locks,
|
|
the locking daemon typically operates in conjunction
|
|
with
|
|
.Xr rpc.statd 8 .
|
|
.Pp
|
|
Options and operands available for
|
|
.Nm :
|
|
.Bl -tag -width indent
|
|
.It Fl d
|
|
The
|
|
.Fl d
|
|
option causes debugging information to be written to syslog, recording
|
|
all RPC transactions to the daemon.
|
|
These messages are logged with level
|
|
.Dv LOG_DEBUG
|
|
and facility
|
|
.Dv LOG_DAEMON .
|
|
Specifying a
|
|
.Ar debug_level
|
|
of 1 results
|
|
in the generation of one log line per protocol operation.
|
|
Higher
|
|
debug levels can be specified, causing display of operation arguments
|
|
and internal operations of the daemon.
|
|
.It Fl g
|
|
The
|
|
.Fl g
|
|
option allow to specify the
|
|
.Ar grace period ,
|
|
in seconds.
|
|
During the grace period
|
|
.Nm
|
|
only accepts requests from hosts which are reinitialising locks which
|
|
existed before the server restart.
|
|
Default is 30 seconds.
|
|
.El
|
|
.Pp
|
|
Error conditions are logged to syslog, irrespective of the debug level,
|
|
using log level
|
|
.Dv LOG_ERR
|
|
and facility
|
|
.Dv LOG_DAEMON .
|
|
.Pp
|
|
The
|
|
.Nm
|
|
utility must NOT be invoked by
|
|
.Xr inetd 8
|
|
because the protocol assumes that the daemon will run from system start time.
|
|
Instead, it should be configured in
|
|
.Xr rc.conf 5
|
|
to run at system startup.

The implementation is based on the specification in

.Sh HISTORY
|
|
A version of
|
|
.Nm
|
|
appeared in
|
|
.Tn SunOS
|
|
4.
|
|
.Sh BUGS
|
|
The current implementation serialises locks requests that could be shared.
