In this configuration, we still don’t worry about internal security.
In this case, the Console Server (CS) has multiple serial ports installed,
connected to the various consoles that you care about.
Any data coming in from each attached device is appended to a log file for that
specific device. (As an administrator, you may need to watch the size of the
log files, and rotate them occasionally.)
In our example, you would use a client (CC) to connect to the console server
(CS), and attach to the console logging session that you want to talk to.
Anything you type on the client goes to the serial console you are talking to,
while anything coming back from that console is logged, and then sent to the
client(s) attached to that session.The client software, and/or the server
software, watch the data stream from the user, looking for meta-characters
coming from the client, to allow for session control.
Some console servers allow more than one client to attach to a single session
at once. All clients see the data coming from the attached device, but only one
client can type to the session. (Conserver behaves in this manner.)
