text: a good way to learn to use these tools is to ping yourself, then look yourself up, go have a whack at tracing your own root, whois is pretty much the same as lookup, as is finger, and portscannin something is deffo a no, no, as if they have any kinda security, they'll capture your i.p addy, and you'll be screwed, basically what i'm sayin is, if all you want to do is learn the command lines, then do it to yourself\n\nR3dm0
