The attached pdf provides a detailed example with all relevant commands on how to:
1. Setup auto-ssh to NetWitness packet-decoder and concentrator from a NetWitness server
2. Bulk change NetWitness packet-decoder and concentrator ssh root password from the NetWitness server
3. Bulk change NetWitness packet-decoder and concentrator iDRAC webUI root password from the NetWitness server
These bulk ssh and iDRAC webUI root password change commands are handy if one has multiple NetWitness hosts that require regular ssh and iDRAC webUI root password changes.
