set-proxy

Script that sets env variables for proxy depending on the configured subnets.

Installation

Thi script is for Linux. Python 3, pip and some Python packages are needed. You can install it in Ubuntu (or Debian based) running:

sudo apt-get install python3 python3-pip
sudo pip3 install netaddr netifaces

In Fedora (or RedHat based) you need to run:

sudo yum install python3 python3-pip
sudo pip3 install netaddr netifaces

To install the script just clone the repo in your home and add an alias for quick execution. Add it to ~/.bashrc so it's ran at the beginning of every non-login interactive shell:

cd ~
git clone https://github.com/bryant1410/set-proxy.git .set-proxy
echo 'alias set-proxy="source $HOME/.set-proxy/set_proxy.sh"' >> ~/.bashrc
echo 'set-proxy' >> ~/.bashrc

Start a new shell in order to see the changes.

To run it whenever you want, do:

set-proxy

Configuration

By default, it sets the proxy proxy.fing.edu.uy:3128 if under subnet 164.0.0.0/8 in eth0 or wlan0. You can change the subnets and interfaces in the file check_subnet.py and the proxy configuration in set_proxy.sh.

In order to keep these environment variables in sudo, run the following:

sudo visudo

Then add the line:

Defaults env_keep += "ftp_proxy http_proxy https_proxy no_proxy"
