Hmm? I think I was talking to someone about this a very long time ago on another site but I can't really remember too much about it. So in a nutshell it depends on the version of the program. What I mean by that is different versions of programs have diff exploits so type in the version of finger or telnet your are testing "heh lol testing" in google and I am sure all kinds of things will come up??? That’s all I know...
