probenis(8)probenis(8)NAMEprobenis - 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 explic‐
itly 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 sec‐
onds). The probenis command takes no action other than to set an exit
code: zero if NIS appears to be running, nonzero otherwise.
