Preventing machines from adding themselves as clients from the command line

Use this information to set from the command line whether machines can add themselves as clients in a NIM environment.

To prevent machines from adding themselves as clients in a NIM environment, set the attribute client_reg=no on the NIM master:
  nim -o change -a client_reg=no master
To allow machines to add themselves as clients of a NIM master, remove the client_reg attribute by setting it to yes on the master:
  nim -o change -a client_reg=yes master
