Description

The following error is displayed after upgrading ADC:
"One or more RPC nodes are configured with default passwords. For enhanced security, you must change the default RPC node password"

Resolution

This is just a warning to set the passwords of RPC node from default to other custom password. It will not cause any other issues.
Refer to Citrix Documentation to change the RPC node password.

Issue/Introduction

To determine which RPC node has the default password:

  1. Run show rpcNode on each appliance.
  2. Compare the encrypted password hashes.
  3. Nodes showing the default hash have the default password.
  4. Change the password on those nodes to secure the environment.

Additional Information

RPC stands for "Remote Procedure Call"

How to Identify Which Node Has the Default RPC Password:

  1. Use the CLI to Show RPC Nodes and Password Hashes
    1. Run the following command on each NetScaler appliance to display RPC node information:
      1. show rpcNode
      2. This command shows the RPC nodes configured on the appliance, including the encrypted password hash.
      3. Compare the encrypted password hashes between nodes.
      4. Nodes with the default password will have the default hash value.
      5. Nodes with changed passwords will show a different hash.
  2. Check HA Pair Nodes
    1. In an HA pair, ensure that both nodes have the same RPC node password configured.
    2. If the hashes differ, it indicates one node is using the default password (or a mismatched password).
  3. Use the NetScaler GUI
    1. Navigate to System > RPC Nodes (if available in your ADC version).
    2. Check the RPC nodes and their password status.
