|
.Nm

.Op Fl d Op Ar debug_level
|
|
.Sh DESCRIPTION
|
|
.Nm Rpc.lockd
|
|
is a daemon which provides file- and record-locking services in an NFS
|
|
environment.
|
|
.Pp
|
|
The following option is available:
|
|
.Bl -tag -width indent
|
|
.It Fl d
|
|
Cause debugging information to be written to syslog, recording
|
|
all RPC transactions to the daemon. These messages are logged with level
|
|
LOG_DEBUG and facility LOG_DAEMON. If debug_level is not specified,
|
|
level 1 is assumed, giving one log line per protocol operation. Higher
|
|
debug levels can be specified, causing display of operation arguments
|
|
and internal operations of the daemon.
|
|
.El
|
|
.Pp
|
|
Error conditions are logged to syslog, irrespective of the debug level,
|
|
using log level LOG_ERR and facility LOG_DAEMON.
|
|
.Pp
|
|
The
|
|
.Nm
|
|
daemon 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 run from
|
|
.Xr rc 8
|
|
after the network has been started.

|
|
.Sh BUGS
|
|
The current implementation provides only the server side of the protocol
|
|
(ie. clients running other OS types can establish locks on a
|
|
.Fx
|
|
fileserver,
|
|
but there is currently no means for a
|
|
.Fx
|
|
client to establish locks).
|
|
.Pp
|
|
Versions 1, 2 and 3 of the protocol are supported. However, only versions
|
|
2 (Unix systems) and 3 (PC-NFS clients) seem to be in common use - the version
|
|
1 support has not been tested due to the lack of version 1 clients against
|
|
which to test.
|
|
.Sh STANDARDS
|
|
The implementation is based on the specification in X/Open CAE Specification
