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
             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

     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.

SEE ALSO    [Toc]    [Back]

STANDARDS    [Toc]    [Back]

     The  implementation  is based on the specification in X/Open
CAE Specification

     872630 66 9

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

     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.
