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
  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, nonzero otherwise.
