Forward the GnuPG agent from macOS to Linux

Your private keys stay on the Mac, or on your YubiKey, and gpg on the Linux host uses them over SSH.

Last tested in October 2026 from macOS with GnuPG 2.5.24 and OpenSSH 10.5 to Debian 13 with GnuPG 2.4.7 and OpenSSH 10.0. You need GnuPG 2.1.17 or newer on both ends and OpenSSH 6.7 or newer.

On the Mac

Install GnuPG and a graphical pinentry. Passphrase and PIN prompts appear on the Mac, so a terminal pinentry won't work for a request that comes from the remote host.

Update (March 2023) (Last checked: Oktober 2024)

Side note: The latest edge build of KeeAgent plugin offers an option for creating a WSL compatible socket. This would be very handy. I already tried to use that socket, but the socket file is currently empty and ssh inside WSL 2 is unable to use it. This appears to be a very new, unreleased and unstable feature. I will follow the development of it and when it finally works (well, for me) I will update this HOWTO. But until then, please use the proven wsl-ssh-agent/npiperelay.exe approach below.

Thanks to the instructions for WSL 2 of the wsl-ssh-agent project, KeeAgent works great in WSL 2 now: https://github.com/rupor-github/wsl-ssh-agent#wsl-2-compatibility The approach uses minimal and well-maintained tools.

Hyperlinks (a.k.a. HTML-like anchors) in terminal emulators

[ Update 2025-03-24: Commenting is disabled permanently. Previous comments are archived at web.archive.org. ]

---

Most of the terminal emulators auto-detect when a URL appears onscreen and allow to conveniently open them (e.g. via Ctrl+click or Cmd+click, or the right click menu).

It was, however, not possible until now for arbitrary text to point to URLs, just as on webpages.
