RPC.LOCKD(8)		FreeBSD	System Manager's Manual		  RPC.LOCKD(8)

NAME
     rpc.lockd -- NFS file locking daemon

SYNOPSIS
     rpc.lockd [-d [debug_level]]

DESCRIPTION
     Rpc.lockd is a daemon which provides file-	and record-locking services in
     an	NFS environment.

     The following option is available:

     -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	proto-
	     col operation.  Higher debug levels can be	specified, causing
	     display of	operation arguments and	internal operations of the
	     daemon.

     Error conditions are logged to syslog, irrespective of the	debug level,
     using log level LOG_ERR and facility LOG_DAEMON.

     The rpc.lockd daemon must NOT be invoked by inetd(8) because the protocol
     assumes that the daemon will run from system start	time.  Instead,	it
     should be run from	rc(8) after the	network	has been started.

BUGS
     The current implementation	provides only the server side of the protocol
     (ie. clients running other	OS types can establish locks on	a FreeBSD
     fileserver, but there is currently	no means for a FreeBSD client to
     establish locks).

     Versions 1, 2 and 3 of the	protocol are supported.	 However, only ver-
     sions 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.

STANDARDS
     The implementation	is based on the	specification in X/Open	CAE Specifica-
