42 .Nd NFS file locking daemon
45 .Op Fl d Op Ar debug_level
48 is a daemon which provides file- and record-locking services in an NFS
51 The following option is available:
52 .Bl -tag -width indent
54 Cause debugging information to be written to syslog, recording
55 all RPC transactions to the daemon. These messages are logged with level
56 LOG_DEBUG and facility LOG_DAEMON. If debug_level is not specified,
57 level 1 is assumed, giving one log line per protocol operation. Higher
58 debug levels can be specified, causing display of operation arguments
59 and internal operations of the daemon.
62 Error conditions are logged to syslog, irrespective of the debug level,
63 using log level LOG_ERR and facility LOG_DAEMON.
67 daemon must NOT be invoked by
69 because the protocol assumes that the daemon will run from system start time.
70 Instead, it should be run from
72 after the network has been started.

76 RPC protocol specification for the network lock manager protocol.
83 The implementation is based on the specification in X/Open CAE Specification
84 C218, "Protocols for X/Open PC Interworking: XNFS, Issue 4", ISBN 1 872630 66 9
86 The current implementation provides only the server side of the protocol
87 (ie. clients running other OS types can establish locks on a
90 but there is currently no means for a
92 client to establish locks).
94 Versions 1, 2 and 3 of the protocol are supported. However, only versions
95 2 (Unix systems) and 3 (PC-NFS clients) seem to be in common use - the version
96 1 support has not been tested due to the lack of version 1 clients against
