Using Telnet

"Telnet?" you might say.Yes T-E-L-N-E-T, telnet, or teletype network.For all of you beginners out there telnet is basically a remote access command-line interface.But getting to the point; telnet has been used for many things when it came out such as remote access to a computer but due to low security, it was suggested not to use it altogether.Though not widely used anymore, it still can be a cyber playground for those who like to get their hands dirty in command-line interfaces.With it you can connect to online servers like email enabling you to create emails without the need of a password.One person even created a portion of Star Wars entirely out of characters from a keyboard.I'll tell you how to do both of these things today.
First, to view the clip of star wars go to the start menu then click on run and type in telnet towel.blinkenlights.nl and press enter.It will first open some boring text for a second, then it will play Star Wars with the clever use of letters and symbols to create pictures, like Princess Leia's hair curls will be made out of the @ symbol.
Secondly, to create emails from command prompt first open command prompt by clicking on the star menu>run and type in cmd.(Just to let you know, I am using Gmail's server as an example.You can get a list of servers here for whatever type of mail you want to send.)Now type in telnet yourservername 25.I am going to type in for gmail telnet aspmx.l.google.com 25, 25 meaning port 25 of which you will use to connect to the server.Press enter and it should connect.Type helo making sure that you spell it with one l.It should now say mx.google.com at your service somewhere or whatever your server name is.Now type mail from: , making sure not to make any typing mistakes or using the backspace key, otherwise it won't work.If you don't get the right email the first time try again.It should say OK somewhere.Type rcpt to: .Press enter and it should say OK somewhere.Here is where you start to type your message: type data and press enter.It should say go ahead somewhere.For your subject type Subject:my subject and press enter to start typing the body of your message.Make sure not to make any mistakes because then it will not delete them and it will look like this: hai my neamie ais sipyhgury. When you are finished typing your message press enter two times and type a period.Press enter one more time and if your did it correctly, it will send it.Though it usually says from unknown sender and puts it in the spam box of whoever you are sending it to, but it looks really cool if you memorize the process.
