OmenShell | Manage multiple servers through SSH

Requirements

You need a valid user on the remote system with passwordless access via SSH key.

Configuration

Edit the omen.host file to add the remote servers you want to manage. After the installation this file can be located in the ~/bin directory.

Installation

From a Linux terminal type the following commands:

cd
git clone https://github.com/incognia/OmenShell
cd OmenShell
./install.sh

Dependencies

The option -s requires the Speedtest CLI by Ookla to test the internet bandwith. You need to execute the following commands to install it:

sudo apt-get install curl
curl -s https://packagecloud.io/install/repositories/ookla/speedtest-cli/script.deb.sh | sudo bash
sudo apt-get install speedtest
speedtest --accept-license
