Answer 1

If you want to use wget with a proxy, use the --proxy=on option and export the proxy address with export http_proxy="http://proxy.example.com:8080"

See here: http://tech.gaeatimes.com/index.php/archive/how-to-use-wget-through-proxy/ or check the wget man page https://www.gnu.org/software/wget/manual/wget.html
