SSH Tips and Tricks | Carlos Becker

In this article, the author shares various SSH tips and tricks that can help improve the user experience when working with SSH. These tips include forwarding Yubikey agents, reusing connections, ssh’ing directly into tmux, aliasing commonly used hosts, not adding testing stuff to known_hosts files, making connections last longer, canonicalizing hostnames, and using Yubikey with GitHub without touching it every time. The author also advises caution when enabling these features, especially on shared servers or for public facing SSH connections.
