The SSH-Tunnel-Manager is a bash shell script created to manage ssh tunnels.
This SSH-Tunnel-Manager script aims to setup one or more configured ssh connection with port forwarding. The list of functionality includes the following:
Multiple tunnels can be configured
Flexible configuration to forward mulitiple ports ber connection
Reconnect to the SSH server if connection lost
Log all reconnect attempts to logfile
Manage configured tunnels (start/stop/restart)
Manage tunnels (start/stop/restart) individual by tunnel name
Download & Installation
To install the the script download it from Github and upload it to your server. Copy the example config file "ssh-tunnel-manager.conf.example" to "ssh-tunnel-manager.conf" and change its configuration values. The configuration file contains a description for its configuration items. To see the available commandline options execute "ssh-tunnel-manager.ssh -h".
Connecting to a service on a server that does not expose the service port or connection between servers not exposing there ports publicly is only possible via some kind of VPN or port forwarding. SSH port forwarding provides a simple port forwarding to the service you need to access.
With the SSH-Tunnel-Manager multiple SSH connections to different servers with different portforwardings can be configured. These tunnels can be comfortable managed. The script provides a start command to start the tunnels as well as a stop command to stop the running tunnels. The integrated logic will as well automatically restart the ssh tunnel if the connection to the ssh server should be lost.
The SSH-Tunnel-Manager script will establish a ssh connection for every configured tunnel. Entering the password on every connect can be annoying. I suggest a SSH passwordless login with SSH key setup. This allows the script to run without user interaction.
