wget

Hi there, So I'm trying to learn this a bit better. I know that wget can pull a static copy of a php driven website. I haven't played with httrack too much. I'm wondering if it also will pull a static copy, or if it can pull an exact copy of the dynamic site? PHP driven sites, like Wordpress or...

I want to know more about port scanning. Is it basically just sending http requests to someone else's server and seeing if you get in? Because then you can do that with a giant multicurl and not risk your own ISP banning you. Can an expert give me more info, please

I need a good proxy server that would enable me to use php/cli curl or wget with another ip address. How do I find a paid proxy server that supports curl/wget?
