hello all, i have a problem with command prompt
i was trying out new things like practice with: Nmap, nslookup...
so i was practicing, and i typed like:
nmap and i found the port.
so i telnet to it it was brico.be 80
(that was what i typed in telnet.)
and all of a sudden, command prompt was blanc.
and i hitted enter, and it 'poofed' of of my screen
some information on what that was?
thank you.

What you did was, connect to a web server in port 80, wich is the default port for HTTP protocol. What you saw was the server's response in HTML code.

If you try to open brico.be in your web browser, you will get the same response, but formatted, because your browser connects to the server in the same port you did and can interpret HTML.

Telneting into a machine through port 80 doesn't take you very far in pen testing (you can send raw HTTP commands, but your browser does it better). On the other hand it may give you some important information about the server, like apache version, OS, and more...

Since you are just getting started, I recommend you read allot about the basic stuff like, networking, protocols, etc.

Do the same with netcat (is available for windows) and type in the blank window a valid HTTP Request.
Like this:

nc www.myspace.com 80

GET / HTTP/1.1
Host: www.myspace.com

and after that two times "Enter".

You will see the result. You played a browser - a very very simple browser.

it happens generally with telnet..

this happens when the system is waiting a response from the target..

you must havent seen any message like connection refused or connected when the case happens like this..




but use telnet port while using telnet dont try with por 80..
you cant go far with that..

no need to worry..
