The better alternative is SSH, but Telnet is still fairly useful with
Linux-based devices, including desktop PCs, router firmware, Arduino
and Raspberry Pi.

Window$ has Telnet as well, though their users seldom use it.

I still use Telnet for old time bulletin boards.

I was online a long time ago when direct dial BBS were king. Some of
them have moved onto the internet and you can telnet into them.

It is a bit niche but it is still valid.

I grew up with ExecPc bbs. Year later, could still log in with cc number
of all ones. Need to dig out Telnet to see if it is still there.

Check out Smarties BBS in Hong Kong? Its sysop is trying to keep
DOS-based BBS running....

Telnet sends username and password in plaintext.

This is one reason, a utility by that exact name, may not
be available in Linux. First they made it hard to find, then
later, may have removed it entirely.

Other platforms (my old Mac G4 had it, Windows has it),
they still offer it. They offer it, on the understanding
that the user understands the risks.

The telnet command is used to debug other protocols.
You can specify a port number, and debug your news server
or your email server with it. What you're looking for in
cases like that, is the "login prompt" or similar, coming
back from the thing at the other end. It helps prove a
server is running on a particular port number.

Telnet is less desirable in 2018, for "sessions".
It's not for chatting with your mom. Or for entering
your Unix password, for the entire world to see.

Find a secure version of Telnet, before sending your
username and password to any service.

Even news servers and news clients have this issue.
If you work on port 119 of a news server, your username
and password travel in the clear. Your ISP can see them.
The NSA can see them.

If you use one of the other port numbers, they
support encryption of various sorts.

That's why in the table here, you have choices.

http://www.eternal-september.org/ind...wpage=techinfo

"Client Settings

Server name: news.eternal-september.org
Port : 119 (NNTP)
Port : 563 (encrypted connection NNTPS)
"

If you use Wireshark (a packet tracer), and you're having
trouble with your newsserver, switching to port 119 allows
you to log all the packets in plaintext. And figure out
(as far as your end is concerned), what visible symptoms
of brokenness are present. If the thing is working,
then you can stick with 563 for normal usage. You can
see the low_water and high_water marks on a newsgroup,
and compare to the article numbers in your news-rc file.
(That's for Thunderbird users who "don't see new articles
in their favorite group".)

Obviously, you won't be using your "regular" password
for this service :-)

And in case that isn't clear enough, you should not
use the same password for an email service, as for
your local logins. If you ever need to debug the
email service, the password might end up in the open.
It depends on your technical skill, as to how you can
hide it, and still debug the service. (I don't have the
skillz for debugging over 563, but it's possible.)
