Grand Route Dispatch

Grand Route Dispatch is a python script for routing specific url to Wi-Fi or Ethernet.
This tool is helpful when your company limit access of internal ressources to Ethernet and limit certain services to wifi.

GRD WORKS ONLY ON OS X & LINUX!

How it works

For example, imagine you need to plug your Ethernet cable in order to:

• Print
• Connect to LDAP
• Access internal support websites
• ...

But you can't use Ethernet for streaming music or using dropbox.
You just need to create your own hosts list then give it to GRD and it will automatically create route for you.
NB: Routes will vanish when disconnect Wi-Fi and Ethernet

Create your hosts file

There is only two specific tags. First, !wifi every URLs after this tag and before next one (or EOF) will be routed to Wi-Fi.
Next one is !ethernet, every URLs after this tag until EOF or another tag will be routed to Ethernet.
Empty lines, wrong URLs and lines starting with # will be omitted.
See [example](## Host list example)

Download & use it!

• First, git clone it!
  git clone https://github.com/Miasma87/grand-route-dispatch.git
• Make it executable
  chmod +x grand-route-dispatch.py
• Launch it!
  sudo ./grand-route-dispatch.py

N.B: You should launch it with super-user privileges as route command need it.

Configuration

First of all you will need to write a file listing all the URLs you want to dispatch.
See [Host list example](## Host list example) for file example.

Host list example

!wifi
# Here we will have URLs that will need to be redirected to Wi-Fi
google.com
spotify.com

!ethernet
# Here we will have URLs that will need to be redirected to Ethernet
ldap.yourcompany.com
webmail.yourcompany.com
# Printer IP
10.10.10.10
