"i supose not windows? :p"
why don't you ?
maybe you the "whois" command line is very usefull on linux but there are many usefull tools & langages on windows too and the most people use this OS & in the end ; it's easy to hack ;)
i personal think that its easy on Linux because i have more options i can do.. write me own script and so on.
but on windows you have cain en that kind of thins.. and even the whois command and the wget is avalible on windows.
but i think linux hase more options for doining it then windows...
