This blog post covers how to configure the behavior of an SSH client using the ssh_config file. We will take a look at the use of wildcards and how they can be used to radically simplify your life without bloating your client.
Whether you are looking to add some additional security constraints, minimize failures, or prevent carpal tunnel, ssh_config is an often underutilized, yet powerful tool. Our goal is to make life easier to manage a fleet of servers and users. We’ll do that here by creating a flexible configuration file for our SSH client.
Please note, this post is not about server-side configuration via sshd_config.
