[comp.unix.questions] What is the use of Telnet?

ppg@oasis.icl.co.uk (Philippe Goujard) (05/01/91)

I'm currently developping a version of the ISO Virtual Terminal and I'm
in charge of the Asynchronous mode and Telnet emulation.

I have a good theorical knowledge of telnet (RFC854) and I can use telnet
with our unix machines over TCP/IP. But for me it works more or less like
rlogin. Therefore I cannot realy figure what is telnet used for (or was used
as the rfc is from 1983). 

What do you use telnet for? (and why not "only" rlogin?)
Do you use the "transmit binary" facility? If yes for what purpose?
(transfering files, driving directly the screen?, ...)
Do you use facilities like "Are You There" or "Abort Output" or "Transmit
Go Ahead"?

Please reply by email, I will post a summary if enough interest.

For example, if you want to log in on a machine that doesn't run Unix -
(at least I haven't found out any way to rlogin on a VMS box). Such machines
do exist, incredible though it may seem...

The main use for telnet can be summed up for me as

   1. All the world isn't Unix

as I have used it to talk to non-Unix systems which support
the telnet protocol but for which the concept of rlogin and
.rhosts and /etc/host.equiv would be a bit foreign.

I haven't seen this mentioned before, but one very useful use of the
BSD telnet program (but not the telnet protocol), is that you can
connect to other ports than 23.  Very useful if you want to test any
network based program.  You can e g use the telnet program to play MUD
or forge News articles >:->
