                    How to upload and compile programs


The most obvious and simple way is using FTP:

    bash-2.03$ ls
    program.c
    sh-2.03$ ftp target.edu
    Connected to target.edu.
    220 target.edu FTP server (SunOS 5.6) ready.
    Name: luser
    331 Password required for luser.
    Password:
    230 User luser logged in.
    ftp> put program.c
    200 PORT command successful.
    150 ASCII data connection for program.c
(204.42.253.18,57982).
    226 Transfer complete.
    ftp> quit
    221 Goodbye.

But this is not a really good way. It can create logs that will
make the admin to detect us.

Avoid uploading it with FTP as you can, use cut&paste
instead.




	Here's how to make it: we run a text editor sh-2.03$ pico exploit.c if it doesn't work, try this one: sh-2.03$ vi exploit.c Of course, you must learn how to use vi. Then open another terminal (i mean without x windows, CTRL+ALT+Fx to scape from xwindows to x, ALT+Fx to change to another terminal, ALT+F7 to return xwindows) on your own box and cut the text from it. Change to your target and paste the code so you've 'uploaded' the file. To cut a text from the screen, you need to install the gpm packet from your linux distribution. This program lets you select and cut text with your mouse. If cut&paste doesn't work, you can also type it by hand (they aren't usually large). Once you get the .c file there, here's how to compile: sh-2.03$ gcc program.c -o program and execute: sh-2.03$ ./program Previous Page 5
