tells the ypbind(8)
process on the current machine which NIS server process to communicate with. If server
is down or is not running a NIS server process, it is not discovered until a NIS client process attempts to access a NIS map, at which time ypbind(8)
tests the binding and takes appropriate action.
ypset is most useful for binding a NIS client that is not on the same broadcast network as the closest NIS server, but can also be used for debugging a local network's NIS configuration, testing specific NIS client programs, or binding to a specific server when there are many servers on the local network supplying NIS maps.
The options are as follows:
Set the NIS binding on host instead of the local machine.
Use the NIS domain domain instead of the default domain as returned by domainname(1).
