What is telnet, and why should I use it? --------------------------------------------- The telnet is the most important tool, used by a hacker(a person who would like to know more about the CyberSpace that's around him ;) ). Telnet is given by almost every OS, why almost, because some Linux OS's companies where too cheap to give it with the OS, but it's not a problem, you can always download it(for more info, search at www.google.com). Any way, a telnet program is a clien, and with this telnet clien you can easly connect to different ports(see the most used port list at the end of the tutorial), such as the ftp, pop3, http, etc. ports, well... if the port is open of course ;) II. How do I use TelNet, and for what? -------------------------------------- the Telnet is very easy for use, all you need to do is to give it the address(host) you like to connect to, and from what port would you like to do it. How do you input this data into the telnet? you ask, simple: 1.) For Windows, there are two ways to do so: 1.1) Do a search on you windows folder, on "telnet". After it found, double click, a white window will pop-up, take a look at the upper bar, you'll see "Connect" there, press on it, and then click on the "Remote System", after you'll do so, a small window will pop-up, with three field in it: Host Name _________ Port _________ Term Type _________ In the "Host" field goes the address of the machine you would like to connect to. In the "Port" field goes the port you would liek to connect thru. And in the "Term Type" field just leave the it, as it was(vt100). Ok, now we're set to go, press the Button, and telnet clien will connect to the wanted host, via the wanted port. 1.2) The second way to connect the telnet on a windows machine is by DOS, just go to the "MS-DOS prompt" (START -> PROGRAMS -> MS-DOS prompt). This will give the DOS OS under windows, now you just type "telnet", and after that you just fill the "fields": - The first word(field) after the "telnnet", will be the "host" you would like to connect to. - The Second word(field) after the "hosst", will be the "port", you would like to connect the host thru. Now press "Enter" and telnet will connect to the wanted host. *** NOTE: In the second way we typed the parameters in the DOS prompt, but you type the same in the windows' RUN (START -> RUN). 2.) For Linux/Unix there is only one way to connect: It's the same as the second way for windows, just on a linux/unix machine. Now you know HOW TO connect with telnet, but the main question is where to connect to? And the answer is: EVERY WHERE YOU CAN :) For example, do you know this e-mail address that is giving to you by your ISP?! The one that you need a Program to check the IN/OUT box, well no more! Just find a POP3 tutorial, and can throw those lame programs to hell, the same goes for mIRC(for those two check the http://www.securitywrites.org). III.
