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-
