Running telnet inside an SSH tunnel is different... The Telnet protocol itself makes no promises about the presence OR absence of encryption, and it has a very flexible do/don't/will/won't option negotiation protocol. Kerberos-enabled telnet, in particular, allows for automatic authentication and/or stream encryption, with either enabled or disabled on an invocation-by-invocation basis. This is far from new. I have been using it for over twenty years. -Dave -- Dave McGuire, AK4HZ New Kensington, PA
