A bash script to rule all your SSH tunnels!

You work in an environment that the hosts are behind an SSH gateway? you have multiple tunnels that make your life hard? This tool allows you to handle all your tunnels in one place

How to create your connections file

The file with the SSH tunnel connections must be in this form, is actually the ssh part without the ssh command, each line must is a separate tunnel

ssh_gateway1 -L 33891:windows1:3389
-R 8080:127.0.0.1:80 webserver1
-D 33334 -q -C -N -f ssh_gateway1

How to use the tool

Start tunnels

tunnel_manager.sh connections.csv start

If there no any connectivity issues and the commands in the connections.csv file are correct the tunnels will start in parallel and stay in the background.
