I need to set a system wide proxy setting to automatically search the proxy settings like it's possible in windows.
I use Linux Mint Xfce and don't find any place in the GUI where I'm able to set my proxy settings. I'd also use a terminal to configure some proxy config files if there are any.
Important is, that the proxy settings apply to browsers (chromium, firefox) and apt-get (which also uses http, right?) and are set to auto search for proxy.
I know about the http_proxy, ftp_proxy etc. variables. But I don't know yet how to configure my system to autodiscover proxy settings.
