Buffer Overflow

I know how to USE buffer overflows but how can I make the shellcode (the "\x..\x..\x..." thing)? It seems that the shellcode in linux can be maked by gdb when you disassemble a run-the-/bin/sh-program but my output isn't the same and don't work! And is this possible in windows?? :confused: :confused: :confused:

Hmm...I know a tutorial on this...Lemme find it. I'll post it up here.

Here is a good tut on Exploits and buffer overflows by our own zxtech found in our tutorials database. You can find it Here.

Enjoy.

Here are some buffer overflow tutorials(some have shell code in it):

I believe if you want to write to bin/sh try this:
char shellcode[]=
"/bin/sh";

Thx!
