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).
You must perform this task as superuser on the client. You need the superuser password to the client.
This step initializes the client and creates a NIS_COLD_START file in its /var/nis directory. Use the nisinit command with the -c and -B options.
client1# nisinit -c -B This machine is in the doc.com. NIS+ domain. Setting up NIS+ client ... All done.
An NIS+ server on the same subnet will reply to the broadcast and add its location information into the client's cold-start file.
