The above Trusted Networks will limit access by Users and the Adminis- trator, to the ECS0016 serial ports and network attached hosts, however they do not restrict access by the Administrator to the ECS0016 console server itself. To change the default settings for this access, you will need to edit the IP tables rules (as described in the Advanced section).
Serial Port Cascading
Cascaded Ports enables you to cluster distributed console servers so a large number of serial ports (up to 1000) can be configured and accessed through one IP address and managed through the one Management Con- sole. 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.
ECS0016 clustering connects each Slave to the Master with an SSH con- nection. This is done using public key authentication so the Master can access each Slave using the SSH key pair (rather than using passwords). This ensures secure authenticated communications between Master and Slaves enabling the Slave console server units to be distributed locally on a LAN or remotely around the world.
To set up public key authentication you must first upload your RSA or DSA key pair into the Master console server. Please note: If you do not already have RSA or DSA key pair you will need to create a key pair us- ing ssh keygen, PuTTYgen or a similar tool as detailed in xxxxxxxxxx
1.Select System: Administration on Master’s Management Console
2.Browse to the location you have stored RSA (or DSA) Public Key and upload it to SSH RSA (DSA) Public Key
3.Browse to the stored RSA (or DSA) Private Key and upload it to SSH RSA (DSA) Private Key
