Together with the lockdsrv daemon, lockdclnt implements the Network Lock Manager (NLM). NLM is a service that provides support for working with file locks via NFS. lockdclnt must run on every NLM client computer. It fulfills the following tasks:
When the client issues its first NLM request, lockdclnt determines the address of the NLM server. This address is saved by the client so that it need only be queried again with lockdclnt in exceptional cases.
lockdclnt registers the NLM server with the status daemon statd.
lockdclnt records which NLM server is accessed by the client. The list of NLM servers is periodically compared with the mount table /etc/mnttab: If an entry for a mounted NFS resource is deleted from the mount table, lockdclnt informs the statd status daemon that the associated NLM server no longer needs to be monitored.
lockdclnt establishes an RPC service that is called by statd when the client restarts following a crash. This server again sets the client locks on the server.
lockdclnt is started automatically when NFS is started. If the daemon is not running, the system log file should be checked for error messages from lockdclnt.
