If i wanted to connect to someones computer using telnet, but after port scanning there computer, it shows the only port open is 80, can i connect with that port. If i can, is there anything that i could actually do to there computer through that. If not, how do i connect through another port. How would i open that other port?

start->cmd->"telnet <the_ip_here> 80"

then do:
"get / http/1.0

"

[thats 'two' returns]

and you will be given the default webpage.

haha. maybe someone needs to write up a "l33t hax0ring for skript kiddyz" tutorial.

npa · 08-12-2003, 06:30 PM

you were there once too

Hey, he's moving up in the world. He moved from IIS on Windows to Apache on Unix.

bluedevils1414 · 08-12-2003, 07:43 PM

can anyone tell me what all that up there means though?

Belisarius · 08-12-2003, 08:03 PM

That command, effect-wise, just get's the ID of the server you connected to.

What's actually happening is that you are getting unadulterated HTTP traffic. It's that stuff that web-browsers read in, parse, and then display purdy pictures and colors and things to you.

If you're really interested in this stuff, grab TCP/IP for Dummies. Good primer on this sort of stuff (and if you buy Internet for Dummies instead, you should be beaten with it until harmless).

Really, where I first learned about this was when I took my CS deptartment's make-or-break course. I barely knew Java, and the first assignment was to write a functional, graphical Usenet client.

Ahh, good times. If you really want to learn networking, try that.

thanx i just ordered those two books from amazon. i also wanted to know if there was someway i could open ports on another computer. and once ive opened them and connected to them through telnet, what kind of stuff i could do.

Good grief, you're just screaming "script kiddie".

Belisarius · 08-12-2003, 08:44 PM

Really, all you're doing with Telnet is reading and writing ASCII to a socket. You can do that in almost any programming language. Don't worry about opening ports and junk like that. Try doing some network programming, and you'll get the hang of what's going on.

Learn a language like Java or C, create a simple server to do something like send out e-mail.

This site has all the protocol info you need for it:

yeah thats what joe bruin said earlier too. whats that?

bluedevils1414 · 08-12-2003, 08:49 PM

i mean the script kiddie...wuts that

Belisarius · 08-12-2003, 08:50 PM

Seriously though, here's what you're basically saying with these questions:

Hey, I want to hack into someone's computer but I don't know anything about hacking, or computer networks for that matter. Can you help me?

The answer to that is, at any rate I won't, and so far no one else here will. We can show you a thing or two about computer networks, but we aren't going to show you how to root someone.
