This script was written to make Authenticating with a Remote Host as easy as one command. When you have multiple remote servers that you manage and each one has their own private key, it can become a hassle to manage all of them. Hopefully this script will help make managing those remote hosts and private keys easier.
These instructions are just a recommendation of how you COULD set things up. You dont necessarily have to set things up this way for the script to function. This is how I configured the script on my system.
BEFORE DOING ANYTHING, ENSURE YOUR PRIVATE KEYS HAVE THE CORRECT PERMISSIONS. IF YOU DO NOT DO THIS YOU WILL GET AN ERROR SAYING YOUR KEY IS NOT SECURE AND THE KEY WILL BE REJECTED!
chmod 600 /path/to/keys/privatekey_rsaCLONE THE REPOSITORY
cd ~
git clone https://github.com/ryanc410/easy_ssh.gitADD THE easy_ssh DIRECTORY TO YOUR SYSTEM'S PATH SO YOU CAN EXECUTE THE SCRIPT FROM ANYWHERE.
export PATH="~/easy_ssh/:$PATH"CD INTO THE easy_ssh DIRECTORY AND COPY THE ssh-login.sh SCRIPT TO A NAME OF YOUR REMOTE SERVER. THEN MAKE THE SCRIPT EXECUTABLE.
cd easy_ssh
cp ssh-login.sh DOMAIN.sh
