Changing an RPC node password
To communicate with other Citrix Gateway appliances, each appliance requires knowledge of the other appliances, including how to authenticate on Citrix Gateway. RPC nodes are internal system entities used for system-to-system communication of configuration and session information. One RPC node exists on each Citrix Gateway and stores information, such as the IP addresses of the other Citrix Gateway appliance and the passwords used for authentication. The Citrix Gateway that makes contact with another Citrix Gateway checks the password within the RPC node.
Citrix Gateway requires RPC node passwords on both appliances in a high availability pair. Initially, each Citrix Gateway is configured with the same RPC node password. To enhance security, you should change the default RPC node passwords. You use the configuration utility to configure and change RPC nodes.
RPC nodes are implicitly created when adding a node or adding a Global Server Load Balancing (GSLB) site. You cannot create or delete RPC nodes manually.
Important: You must also secure the network connection between the appliances. You can configure security when you configure the RPC node password by selecting the Secure check box.
To change an RPC node password and enable a secure connection
Navigate to System > Network > RPC.
In the details pane, select the node and then click Edit.
In Password and Confirm Password, type the new password.
In Source IP Address, type the system IP address of the other Citrix Gateway appliance.
Click Secure and then click OK.
