If you really want to learn how to hack and not goto jail, goto your local used computer shop and get some really cheap systems, load Linux, FreeBSD, Windows whatever you want on them and setup a LAN, install some web servers, ftp, whatever you want and hack away to your hearts content. Just dont press charges on your self and you will be fine.
If you want to learn without getting into troubles, this is the best way to do it ! You can get real cheap systems that do the job these days... You can't learn security or hacking just by reading, you need to experiment stuff. Hacking into others computers is bad so following MidNyte advices is the best way to do it !

You could also create your own local network with a friend and experiment together and learn. Having someone else install a computer and you trying to hack it may be more challenging that hack a system that you know the config.

Follow the rules and enjoy the lan hack party with friends !

Hacking can be fun if you follow the rules ! Remember that getting access to ressources on other people computers without their consentment IS ILLEGAL !
