Statd

Statd is a daemon that cooperates with statd daemons on other hosts to provide a host status monitoring service. The daemon accepts requests from programs running on the local host (typically, lockd(8), the NFS lock manager) to monitor the status of specified hosts. If a monitored host reboots, the remote daemon will notify the local daemon, which in turn will notify the local program(s) that requested the monitoring service. Conversely, if the local host reboots, when the statd restarts, it will notify the hosts that were being monitored at the time of the crash.
