How to config http proxy in Debian xfce4

Why http proxy

Many entreprises do not allow their employee visit web site for private reason. A config http proxy is obligate. Unlike Unity on Ubuntu, xfce4 on Debian have no option Network Proxy Setting, so we have to set it in different way.

How To

There are two utilisation : apt-get type and general web browser.

apt-get

sudo sh -c 'echo "Acquire::http::proxy \"http://XXX.XXX.XXX.XXX:YYYY/\";" >> /etc/apt/apt.conf'

In here XXX.XXX.XXX.XXX is proxy server IP and YYYY is proxy server port.

general web browser

sudo sh -c 'echo "export http_proxy=\"http://XXX.XXX.XXX.XXX:YYYY\"\nexport proxy=\"http://XXX.XXX.XXX.XXX:YYYY\"" >> /etc/profile.d/proxy.sh'
source /etc/profile.d/proxy.sh

about SSL

on little surprise with https connexion, navigator refuse de show the content of web page. A trick is add correct dns IP at /etc/network/interfaces then restart networking service.

Done.
