Ärende: Telnet Vs SSH
=====================
Hello Michel,

You make it sound as though users are being forced to progress through dial-up
-> Telnet -> Web -> SSH, which is nonsense. Those technologies are simply
alternative means of connecting to a BBS.  None are compulsory and there is
certainly no need to progress through them in any kind of sequence.

You missed my point.  Do you suggest that the user is authenticated on the
basis of a static IP address?  Perhaps you meant once each session, but you
have still not explained what mechanisms you would use for authentication and
encryption.

What about them.  Do you expect BBS users users to register a domain name just
so that they can connect to a BBS?

What reason?  Describe a scenario in which this makes sense.

Any client platform capable of running SSH should also be capable of running
SFTP.  It may also be possible to use traditional BBS file transfer protocols
such as XModem, Kermit etc. over an SSH connection.
