probenis(8) System Manager's Manual 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 yp- bind 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 (cur- rently 25 seconds). The probenis command takes no action other than to set an exit code: zero if NIS appears to be running, non zero other- wise.
