13.5 telnet

- -

Someone once stated that telnet(1) was the coolest thing he -had ever seen on computers. The ability to remotely log in and do stuff on another -computer is what separates Unix and Unix-like operating systems from other operating -systems.

- -

telnet allows you to log in to a computer, just as if you -were sitting at the terminal. Once your username and password are verified, you are given -a shell prompt. From here, you can do anything requiring a text console. Compose email, -read newsgroups, move files around, and so on. If you are running X and you telnet to another machine, you can run X programs on the remote -computer and display them on yours.

- -

To login to a remote machine, use this syntax:

- - - - - -
-
-% telnet <hostname>
-
-
- -

If the host responds, you will receive a login prompt. Give it your username and -password. That's it. You are now at a shell. To quit your telnet session, use either the -exit command or the logout command.

- -
- - - - - -
Warning -

telnet does not encrypt the information it sends. Everything -is sent in plain text, even passwords. It is not advisable to use telnet over the Internet. Instead, consider the Secure Shell. It encrypts all traffic and is available for free.

13.5.1 The other use of telnet

- -

Now that we have convinced you not to use the telnet protocol anymore to log into a -remote machine, we'll show you a couple of useful ways to use telnet.

- -

You can also use the telnet command to connect to a host on a -certain port.

- - - - - -
-
-% telnet <hostname> [port]
-
-
- -

This can be quite handy when you quickly need to test a certain service, and you need -full control over the commands, and you need to see what exactly is going on. You can -interactively test or use an SMTP server, a POP3 server, an HTTP server, etc. this -way.

- -

In the next figure you'll see how you can telnet to a HTTP -server on port 80, and get some basic information from it.

You can do the same for other plain-text protocols, as long as you know what port to -connect to, and what the commands are.
