Broadcast Initialization

This method initializes an NIS+ client by sending an IP broadcast on the client's subnet.

This is the simplest way to configure a client but is also the least secure. The NIS+ server that responds to the broadcast sends the client all the information that the client needs in its cold-start file, including the server's public key. Presumably, only an NIS+ server will respond to the broadcast. However, the client has no way of knowing whether the machine that responded to the broadcast is indeed a trusted server. As a result, this method is only recommended for sites with small, secure networks.

Security Considerations

You must perform this task as superuser on the client.

Prerequisites

At least one NIS+ server must exist on the same subnet as the client. The client must use the same Diffie-Hellman key lengths as those on the master server. See nisauthconf(1M).

Information You Need

You need the superuser password to the client.
