do you really NEED "telnet" ?
" ssh " is what is normally used in the twenty first century ( with exceptions )
by default on most distros telnet, if even installed, is disabled by default.
can you also include what your operating system is ?
we need to know that to help.

Some examples here. http://www.cyberciti.biz/faq/how-do-...reebsd-system/
Usually you would want to test telnet locally or use behind a good firewall or a non-internet computer. As JohnVV suggested, ssh is the more secure way.
There are also examples of telnet in a vpn tunnel if you need it.

first you need to download/use putty to connect to the server (you do not need to install, just download and run). Next, in putty you will enter the name of that host (or ip) and select protocol. We suggest ssh, but you can also select telnet.

You were told what SSH is, in the previous replies, and Google has lots of good explanations too.
SSH is a SECURE method of remote access...you can use it as you use Telnet, but it's secure, and also provides file transfer capabilities. Again TELNET SHOULD NOT BE USED AT ALL, unless there is a very, VERY good reason to. SSH is already installed on your server...start it with "/etc/init.d/sshd start", and it should fire up. Then, from your putty client, connect using SSH to port 22. Done, and your server won't be insecure.

You are right, telnet should be avoided. But telnet is quite good for practicing (how to set up a simple service), so why not? Later on he will definitely not use it any more....

Window 7 and later don't include a telnet client. You'd need to install putty anyway to use it, so ssh would be an obvious choice anyway.
For telnet, you need to install the server and configure the telnetd to start.
Make sure you use xinetd to restrict where connections can come from and bind the interface. Firewall rules will be needed to isolate telnet traffic. This would include the server and the routers. Look at access.conf to control logins.
Again however, you have no valid reason to use telnet instead of ssh. Please use ssh instead.
