NAME    [Toc]    [Back]

     rpc.lockd - NFS file locking daemon

SYNOPSIS    [Toc]    [Back]

     rpc.lockd [-d [debug_level]]

DESCRIPTION    [Toc]    [Back]

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

     The options are as follows:

     -d [debug_level]
             Write debugging information 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
protocol 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.

     The  implementation  is based on the specification in X/Open

BUGS    [Toc]    [Back]

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

     Versions 1, 2 and 3 of the protocol are supported.  However,
only versions
  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.
