Unset http_proxy environment variable

Question

Updated 11/03: After doing some test with your suggestions, I only can be sure about one thing: there is something related to the graphical environment, because if I login through ssh or using a virtual terminal, the variable is not defined. Any new idea?

I have defined in some persistent way the http_proxy variable. Always I open a terminal, I have the http_proxy already defined.

This is not my desired behaviour, so I'm looking where I defined the http_proxy environment variable.

I'm pretty sure that is something user related, because with other users in the same computer I don't have the problem.

I have checked the .bashrc and other bash-related configuration files, but none of them include the http_proxy variable definition.

Obviously, I can unset the variable without any problem, but I want to know where the hell is the variable defined.

Answer 1

Yuo could try a grep in your home directory or in etc. Something like:

 $ cd ~ 
~$ grep -Ri http_proxy *

Answer 2

The environment variables are saved in /etc/environment

cat /etc/environment | grep "http_proxy"

And proxy for aptitude are save in /etc/apt/apt.conf

cat /etc/apt/apt.conf | grep "http::proxy"

I don't know if this question already has an answer, but this is my /etc/environment:

PATH="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games"
http_proxy="http://192.168.0.1:8080"
ftp_proxy="ftp://192.168.0.1:8080"
https_proxy="https://192.168.0.1:8080"
export http_proxy ftp_proxy https_proxy

I was facing similar problem (after using Fiddler proxy to debug some stuff - I guess that was the source of problems).

Clearing out gconf dir:

rm ~/gconf/system/proxy -R
rm ~/gconf/system/http_proxy -R

And relogging did the trick.
