I would like to setup the proxy from a /etc/network/interfaces file, which has been enhanced with guessnet-magic; so depending on the network I end up using I want to setup the system wide proxy. –  blueyed Aug 11 '11 at 18:44

Depending on your needs you could add

   http_proxy="http://your.proxy.here:3128/"
   https_proxy="http://your.proxy.here:3128/"
   ftp_proxy="http://your.proxy.here:3128/"

to /etc/environment to have them set by the login-process.

would this apply the proxy settings even if no one logs in? Ideally, I don't want to have to arse around on the machine, just to update it or what not. –  thecoshman Apr 15 '10 at 11:59
    
Typo: cat /etc/environment –  medigeek Jan 9 '12 at 8:58
    
Fixed, thanks medigeek –  Lairsdragon Sep 13 '12 at 17:36
    
There is also AUTO_PROXY for URL to PAC file formats. –  Wernight Aug 26 at 7:50

@Lairsdragon is correct (set /etc/environment), but there are more nuances.

An application will typically need to be run with this environment in place, for instance, from a login shell. That said, it's even more complex than that:

  • Many applications, especially servers are smart enough to consult /etc/environment.
  • Many don't consult /etc/enironment.
  • Some applications don't support proxies at all.
  • Others are configured with their own configuration files.
  • Still others will read from a different global file (like the gconf registry).

To really set something, you need to read the documentation on a particular application you are interested in to make sure you have set the correct file. Chances are, it will talk about how to set up a http_proxy somewhere in it's docs if it supports this.

This is similar on all operating systems. Setting network proxies is a confusing mess with many different and varied approaches to solving this problem.

Whilst this may theoretically answer the question, it would be preferable to include the essential parts of the answer here, and provide the link for reference. –  Mark Henderson May 22 '12 at 2:03

To proxy updates, add a new file called 01proxy to your /etc/apt/apt.conf.d/ directory with the following line:

Acquire::http::proxy "http://[user]:[password]@[server_ip_or_name]:[port#]";

Substitute the user name/password used to log into the proxy (if required), the server ip or fully-resolved name, and the proxy port # to use when adding this line.
