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 or not 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 a reply to be received or a	timeout.  Unless changed on the	com-
  mand 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, nonzero otherwise.
