The two methods for configuring a machine to use NIS as its naming service are explained below.
# ypinit —c
You will be asked to name NIS servers from which the client obtains naming service information. You can list as many master or slave servers as you want. The servers that you list can be located anywhere in the domain. It is a better practice to first list the servers closest (in network terms) to the machine, than those that are on more distant parts of the net.
# domainname doc.com
# ypbind -broadcast
When you run ypbind, it searches the local subnet for an NIS server. If it finds a subnet, ypbind binds to it. This search is referred to as broadcasting. If there is no NIS server on the client's local subnet, ypbind fails to bind and the client machine is not able to obtain namespace data from the NIS service.
