Preventing Machines from Adding Themselves as Clients

Machines may add themselves as clients in NIM environments by using the niminit command and specifying the hostname of a NIM master. In some environments, administrators may want total control over which machines are added as clients of their masters. To prevent clients from adding themselves to a NIM environment, an administrator can use the client_reg attribute.

From SMIT

The option to allow clients to add themselves to a NIM environment can be changed from the SMIT interface by typing the SMIT fast path:

  smit nim_client_reg

From the Command Line

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
