When quoting my question you must have read it.

OK, thanks.  lxterminal has been in routine use here for more 
than five years.  As we are on the subject: does anyone give 
a password to begin every lxterminal session?

localhost is a special case.  "telnet localhost" is legitimate.

In practice, it performs fairly well.

Different but both give a "shell session" or "console" or 
whatever the correct name.

OK, another topic to add here.
It's a wiki.  If interested, please work on it.

I might have mentioned that I use some software not in a Debian 
package but many others do also.  Didn't strike me as an essential 
point.  Not even interesting to most readers.  "Authentication for 
telnet" is a fairly specific topic.  Oh well.  Solved now.
