Here ya go

What exactly do you want to learn?

im not exactly sure were i want to  start off in backtrack 4. i read something on sniffing. i have a good idea about arp spoofing and injections. how would a hacker benefit from that? im right now trying to use arp spoofing to capture my router password when i log into it. (my router password not my wpa key) is that possable? im using DSniff. should i be using a different sniffer? thanks alot. and anything that you could tell me, or any tutorials pertaining to backtrack 4 would help alot. i know thats pretty vague. sorry

You can use ARP spoofing to capture passwords, etc.  By spoofing ARP, you can use tools like ettercap (or others) to play man-in-the-middle for SSL, which would enable you to capture and view, in clear text, the usernames and passwords passed to https login screens and other https 'protected' pages / sites.  I haven't specifically used dsniff for this type of activity, myself, so unsure how that fares, but I'm sure there are likely tutorials on the web for it, if it's the right tool for the job.
