To start the appropriate NFS client daemons, you can typically use a system initialization script called "nfslock" or "nfsmount". Typically, this script will start rpc.statd, which is all the NFS 3 client needs -- rpc.statd allows file locking to work properly. Once all your client services are set up, running rpcinfo on the local machine will display output that looks like this:

# rpcinfo 
   program vers proto   port
    100000    2   tcp    111  portmapper
    100000    2   udp    111  portmapper
    100024    1   udp  32768  status
    100024    1   tcp  32768  status

You can also perform this check from a remote system by typing rpcinfo -p myhost, as follows:

# rpcinfo -p sidekick
   program vers proto   port
    100000    2   tcp    111  portmapper
    100000    2   udp    111  portmapper
    100024    1   udp  32768  status
    100024    1   tcp  32768  status
