NetCat, what is it and how do i use it ? i know i can hack www.hulla-balloo.com/hack/ and stuff like that but how do i do.

does any have a good tut?

[SirDirge]

NetCat is a tool which is capable of doing just about everything. One of its most used features is the Telnet server where you infect somebody with NetCat and then use normal telnet to connect that the infected computer.
A book that teaches you a lot about NetCat is Hacking Exposed (yes I know it is a very skript kiddy book).

NetCat is exzact;y whan SirDirge Said it is . a rather good guide on how to use netcat is at HappyHacker.org . Happy Hacking !!!!

[i2c]

netcat is great, you dont have to use it for malicous purposes, can use it for scheduled tasks and such across a network,

also the source is availible and its nice source code

Ive used netcat to send information like log files and stuff to another computer and the great thing about it is that u can use batch files,

I found this for u you may find it useful

I use netcat for:

hosting and sending files
backdoor
push backdoor
relaying traffic

[THE RADICAL]

Netcat is a very powerful tool and is often refered to as a swiss army knife becasue of the many versitile things you can do with it.

Tedob1 has done a great job of covering the program...
Just have a peek at these tuts that were written...

They're in order from day 1-4.

im very happy for the many and quick answers i still havnt even read it all (but i will do).

but right now i would like to know how to make a server send back some information that is given to it by you.

this is an example

(i write some kind of a command)
(then i write

GET /chat/gfx/actors/white/boy/clothes/945.gif HTTP/1.1
Connection: keep-alive
User-Agent: Mozilla/4.0 (Windows XP 5.1)
Host: 80.69.224.158
Accept: text/html, image/gif, image/jpeg, *; q=.2, */*; q=.2

after this is written i will recieve this from the server:

GET /chat/gfx/actors/white/boy/clothes/945.gif HTTP/1.1
Connection: keep-alive
User-Agent: Mozilla/4.0 (Windows XP 5.1)
Host: 80.69.224.158
Accept: text/html, image/gif, image/jpeg, *; q=.2, */*; q=.2

hope its possible! if it is i would be xtremly happy if someone could xplain how to do it or link to a tut about it.

i appriciate your help!

thanks,

Netcat is a very useful tool for lots of reasons , and by which shade of hat you are.It is often thought of as the TCP/IP Swiss Army Knife , because it has so many different functions . But sir dirge , Let me ask you this. Why is Hacking Exposed A Script Kiddy book ? I found it very informative and helpful on securing my systems and learning how attacks work. Hacking Linux Exposed is even better.
So I really don't know what you mean by Script Kiddy book , but oh well I guess everyone has different opinions.

[Tedob1]

could you explain that a little more. are you trying to capture and view the output from your browser as the server sees it or do you want to make an echo server? for which you will have to install netcat and then run two instances of it on the server, piping one to the other and sending it back to a nc listener on your computer. in other words you need access to the server

[DDingo]

its because i will change a gif fil to a other gif file and i know that youll get:

GET /chat/gfx/actors/white/boy/clothes/945.gif HTTP/1.1
Connection: keep-alive
User-Agent: Mozilla/4.0 (Windows XP 5.1)
Host: 80.69.224.158
Accept: text/html, image/gif, image/jpeg, *; q=.2, */*; q=.2

from the server when the pic is normaly changed

i yust wont to make the server send:

GET /chat/gfx/actors/white/boy/clothes/945.gif HTTP/1.1
Connection: keep-alive
User-Agent: Mozilla/4.0 (Windows XP 5.1)
Host: 80.69.224.158
Accept: text/html, image/gif, image/jpeg, *; q=.2, */*; q=.2

to me and ill hope the pic is gonna change

thanks
