Mac OS X Installation Procedure

To setup NIS service type following as root:

 rpcinfo -p

If the portmapper is not running, you'll get the message

 rpcinfo: can't contact portmapper: RPC: remote system error - Connection refused

To fix that type:

 sudo launchctl start com.apple.portmap

Repeat check, you should see something like:

 program vers proto   port
   100000    2   tcp    111  portmapper
   100000    2   udp    111  portmapper
