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.
