I am running Linux Mint 11 (Katya) with GNOME 2 and am behind a corporate proxy. I've gone into the Network Proxy Preferences and put in my auto-configuration URL, and this seems to work for things like Pidgin and Chrome (though not Thunderbird...), but it does not affect programs that I run from the terminal, e.g. ssh, telnet, git, et al. I have hit "Apply System-Wide..." button in Network Proxy Preferences, which prompts me for my password twice, but it doesn't seem to help. 

Any thoughts?
