any one know how to hack / over ride blocking and filtering software?

[Matt]

well in the school i go to they have blocking and filtering software which is rather powerful and is very smart i mean it can track your user on the school computer and what computer you were on and what you were doing. they have obviusly blocked all access to the camand pompts and the way to over ride this would mean my school would see me doing it in seconds and catch me. the reason i want to be able to over ride the system as it seems to much of a challenge and i also feel that beeing able to get into someones user and see what ever they are doing is a gross invasion of privcy. unfortunatly i am not sure what package my school use to do this and am currently going to find out which software brand it is but it seems to be alot like anther one i found on the web http://www.responsiblesurfing.com/products/school-edition/learn-more/blocking_filtering/ just a little bit more freedom if anyone knows the answer to this please share your knowledge and thank you for taking the time to help
