Sourceroute

Do you have multiple nics in linux? Ever done a ip route show and realized that linux is only using one of the nics for outbound traffic? This issue explained in greater detail at https://kindlund.wordpress.com/2007/11/19/configuring-multiple-default-routes-in-linux/.

This python script automates the manual procedure listed on that webpage, by determining the ip information needed and running the iproute2 utilities to install those ip rules.

Installation:

• Requires Python 3.
• Install required libraries by doing a: pip install -r requirements.txt

Usage: Add rules for an interface by doing python3 Sourceroute.py --up InterfaceName Delete rules for an interface by doing python3 Sourceroute.py --down InterfaceName

This may be able to be automated in linux by using the if-up.local script.

If you have any suggestions feel free to contact me.
