probenis(8)
NAME
  probenis - Probes for existence of NIS server

SYNOPSIS
  /usr/sbin/probenis [-t timeout] domain

DESCRIPTION
  The probenis command probes the network to determine whether NIS is
  available.  Although part of the JOIN package it does not explicitly depend
  on the configuration database, and can be used standalone.  It is chiefly
  of use on nomadic machines to prevent the invocation of ypbind on a network
  where NIS is unavailable.

  It uses broadcast RPC to make a call to YPPROC_DOMAIN_NONACK, and then
  waits for until either a reply is received or a timeout.  Unless changed on
  the command line the default timeout for RPC is used (currently 25
  seconds).  The probenis command takes no action other than to set an exit
  code: zero if NIS appears to be running, non zero otherwise.
