    NAME

    
    
    rpc.lockd
    
     - NFS file locking daemon
    
     
    

    SYNOPSIS

    [-d debug_level ] [-g grace period ] [-h bindip ] [-p port ]  

    DESCRIPTION

    The utility provides monitored and unmonitored file and record locking services in an NFS environment. To monitor the status of hosts requesting locks, the locking daemon typically operates in conjunction with rpc.statd8.

    Options and operands available for :

    -d
    The -d option causes 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 Specifying a debug_level of 1 results in the generation of one log line per protocol operation. Higher debug levels can be specified, causing display of operation arguments and internal operations of the daemon.
    -g
    The -g option allow to specify the grace period in seconds. During the grace period only accepts requests from hosts which are reinitialising locks which existed before the server restart. Default is 30 seconds.
    -h bindip
    Specify specific IP addresses to bind to. This option may be specified multiple times. If no -h option is specified, will bind to INADDR_ANY Note that when specifying IP addresses with -h will automatically add 127.0.0.1 and if IPv6 is enabled, ::1 to the list.
    -p
    The -p option allow to force the daemon to bind to the specified port for both AF_INET and AF_INET6 address families.

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

    The utility must NOT be invoked by inetd(8) because the protocol assumes that the daemon will run from system start time. Instead, it should be configured in rc.conf5 to run at system startup.
