NAME    [Toc]    [Back]

     statd - network status monitor daemon

SYNOPSIS    [Toc]    [Back]

     /usr/etc/rpc.statd

DESCRIPTION    [Toc]    [Back]

     statd is an intermediate version of the status monitor.  It implements a
     simple protocol that allows applications to monitor the status of other
     machines.	lockd(1M) uses statd to	detect both client and server
     failures.

     statd is started during system initialization if the chkconfig(1M)	lockd
     flag is set on.

     Applications use RPC to register machines they want monitored by statd.
     The status	monitor	maintains a database of	machines to track and the
     corresponding applications	to notify of crashes.  It also maintains a
     database of machines to notify upon recovery of its own host machine and
     a counter of the number of	times it has "recovered."
