I want to setup a console server like a 2600 or something with a 16 or 32 port async module and allow users to access only certain ports/lines by reverse telnet based on login credentials.

For example, user joe can reverse telnet to ports 1 and 2, while user jane can reverse telnet to ports 3 and 4. User Jon can reverse telnet to ports 1 through to 6.

Is there a way to make this work? A document somewhere that outlines what's involved?

Thanks in advance.
