Since I joined Charm, I’ve been working and learning more about SSH, and I thought I would share a few quick tips and tricks with you. Forward Yubikey Agent If you use a Yubikey (you should), you can use it in your remotes by having the key in a SSH agent and forwarding it. To manage the agent, I strongly recommend yubikey-agent. You can then forward it in your ~/.ssh/config like the following:
  • airgapped@piefed.socialEnglish

    Nice tips! Personally will use SSH aliases and canonicalised hostnames.

    Other topics covered in post:

    • Forward Yubikey Agent
    • Reuse connections
    • SSH straight into tmux
    • Alias commonly used hosts
    • Do not add testing stuff to ~/.ssh/known_hosts
    • Make connections last longer
    • Canonicalize hostnames
    • Yubikey and GitHub, without touching it every time
