use ssh instead of telnet about mapscii HOT 6 OPEN

Telnet is not shipping with macOS for five years now. SSH would be greatly appreciated.

I agree with the "unsecureness" in terms of not encrypted text traffic - though in this specific (arty) use case, it was about demonstrating what the telnet protocol has to offer "nowadays" vs. no real security impact :)

Besides that, there was a ssh based test implementation back in the prototype days but the upstream lib implementing the server lacked some core features like supporting raw parsing to support mouse interaction. The current telnet sever is based on node-telnet - definitely worth reevaluating the current state of ssh2 libraries to offer a ssh access as well.

With libssh, this could be done quite easily, I think.

I think Mosh should be recommended since its lower latency significantly improves the UX of interactive CLI applications.

I've never heard of it but it looks like it could be a option. The only downside is that it is not installed by default in most cases

It initializes sessions using SSH, so for regular remote shell operation is is purely opt-in.
I think connecting Mosh to mapscii isn't as straightforward though, as AFAIK you wouldn't want a full shell running "in between"?
