51 utility provides monitored and unmonitored file and record locking services
52 in an NFS environment.
53 To monitor the status of hosts requesting locks,
54 the locking daemon typically operates in conjunction
58 Options and operands available for

64 option causes debugging information to be written to syslog, recording
65 all RPC transactions to the daemon.
66 These messages are logged with level
73 in the generation of one log line per protocol operation.
75 debug levels can be specified, causing display of operation arguments
76 and internal operations of the daemon.

86 existed before the server restart.
87 Default is 30 seconds.
89 Specify specific IP addresses to bind to.
90 This option may be specified multiple times.
97 Note that when specifying IP addresses with
100 will automatically add
102 and if IPv6 is enabled,
108 option allow to force the daemon to bind to the specified
110 for both AF_INET and AF_INET6 address families.
113 Error conditions are logged to syslog, irrespective of the debug level,
121 utility must NOT be invoked by
123 because the protocol assumes that the daemon will run from system start time.
124 Instead, it should be configured in
126 to run at system startup.
