Note The above Trusted Networks will limit access by Users and the Administrator to the console serial ports. However they do not restrict access by the Administrator to the Console Server itself or to attached hosts. To change the default settings for this access, you will to need to edit the IPtables rules as described in the Chapter 14 - Advanced.

4.6Serial Port Cascading

Cascaded Ports enables you to cluster distributed Console Servers so that a large number of serial ports (up to 1000) can be configured and accessed through one IP address and managed through the one Management Console. One Console Server, the Master, controls other Console Servers as Slave units and all the serial ports on the Slave units appear as if they are part of the Master.

Each Slave connects to the Master with an SSH connection using public key authentication. So the Master accesses each Slave using an SSH key pair, rather than using passwords, ensuring secure authenticated communications. So the Slave Console Server units can be distributed locally on a LAN or remotely over public networks around the world.

4.6.1 Automatically generate and upload SSH keys

To set up public key authentication, you must first generate an RSA or DSA key pair and upload them into the Master and Slave Console Servers. This can all be done automatically from the Master:

Select System: Administration on Master’s Management Console

Check Generate SSH keys automatically and click Apply
