Ubuntu mysterious proxy [closed]

Question

Can't find where my proxy settings are stored.

I'm on Ubuntu 12.04. Once upon a time I created a "manual" proxy through Network app GUI. Turned it off same way but now I everytime I use shell I have to "empty" proxies with export http_proxy="" and so on.

It's there.

env | grep proxy

• http_proxy=http://proxy1.bsu:3128/
• https_proxy=https://proxy1.bsu:3128/

Proxy is up but where?

• /etc/environment - not there
• /etc/apt/apt.conf - not there
• /etc/apt/apt.conf.d/ folder - not there
• /etc/profile - not there
• /etc/bash.bashrc - not there
• ~/.bashrc - not there
• ~/.profile - not there
• ~/.bash_profile - not there
• ~/.bash_login - not there
• ~/.pam_environment - not there

Ran gsettings set org.gnome.system.proxy mode 'none' with no effect. Tried through gconf-editor \ dconf-editor still no luck. I tried to update system with apt-get update too. Logged out and in, restarted shell sessions, etc.

It's more like superuser q, but still.

Even bruteforce method of grep -rl proxy1.bsu / didn't find any files.
Had to override variables in ~/.bashrc

Probably my system's bug.
