Umm, no matter where you go it'll be logged, or at elast shoudl be, and what are you trying to accompolish here? I'll assume you mean 'IP address' when you say 'telnet numbers'. A proper address to give you would depend on what it is you are looking to do.
ok, a bad attempt is one that you dont have proper login and password for so any attempt you make will be a bad one since you are not authorized to use any unix systems and from what I see from your posts you wouldn't know what to do even if you did. I suggest searching google for 'free unix shells' get a free shell and play around. After about an hour you will get board and go back to playing with your barbie dolls.
