I open the file like this, with hopping:

C-x C-f /ssh:b0ef@ximian|sudo:ximian:/etc/nixos/configuration.nix RET

If I call org-store link, I get this:

[[file:/sudo:root@ximian:/etc/nixos/configuration.nix::{ config, pkgs, ... }:]]

This is not correct, cause it has removed the hop and when trying to open, I get:

tramp-error: Host name ‘ximian’ does not match ‘\`\(?:spartacus\|\(?:127\.0\.0\.1\|::1\|localhost[46]?\)\)\'’

If I use scp as suggested, I get:

Error in post-command-hook (ivy--queue-exhibit): (user-error "Method ‘scp’ is not supported for multi-hops.")
  • Works for me: I do C-x f /sudo::/etc/fstab, store the link with C-c l. open an Org mode file, insert the the link with C-c C-l and the link works. It shows [file:/sudo:root@<hostname>:/etc/fstab] where <hostname> is the FQDN of localhost. You need to give us more information about what you are doing exactly.

  • First of all, I don't understand how you do "C-x f /sudo::/etc/fstab", cause that's opening a local file, yet your link is a network file?;) Sep 19, 2023 at 17:36
  • (I meant C-x C-f of course, but you knew that :-) ) The link is a file: link: it doesn't know whether the referent is a local or a remote file. That's determined by the path. So open the file (local e.g. /sudo:;/etc/fstab or remote using e.g. /scp:root@ximian:/etc/nixos/configuration.nix, do C-c l in the file and then insert the link in your Org mode file with C-c C-l - then test it.

  • BTW, the tramp sudo method is a local method: it just allows you to access a local file as a different user. You have to use something like the ssh or scp methods for remote access.

  • This command: "/scp:root@ximian:/etc/nixos/configuration.nix" would mean that the ssh server allows root logins. I'm trying to hop, first login as b0ef, then sudo on the remote system to root Sep 20, 2023 at 5:46

There are two possible solutions.

  1. Save the hop. Set tramp-save-ad-hoc-proxies to t. With this setting, Tramp remembers that /sudo:root@ximian: has to use the full path /ssh:b0ef@ximian|sudo:ximian:.

  2. Use expanded file names. In Tramp 2.6.1 (Emacs 29.2, or from GNU ELPA), set tramp-show-ad-hoc-proxies to t. By this, all hops are kept, also when you save it.

See the Tramp manual

N.B.: scp cannot be used for multi-hop file names.

  • Hmm, I still get the same link, even when I (setq tramp-show-ad-hoc-proxies t) Sep 20, 2023 at 7:13
  • Which Emacs / Tramp version are you using? Sep 20, 2023 at 16:22
  • GNU Emacs 29.1 (build 1, x86_64-pc-linux-gnu, X toolkit, cairo version 1.16.0, Xaw3d scroll bars) and Tramp Ah, ok, Emacs-29.2;). That's pretty recent;) ok, grabbing it and reporting back. Hmm, I don't even have access to an Emacs-29.2 in NixOS Unstable;) Sep 20, 2023 at 19:44
  • Emacs 29.2. isn't released yet, I'm building from git. Your better option is to install Tramp from GNU ELPA. Note that there is a bug in Emacs 29.1 which prevents Tramp installation, see elpa.gnu.org/packages/tramp.html for mitigation action. Sep 21, 2023 at 6:33
  • Thank you;) I've installed Emacs git, so the links works now;) Nov 11, 2023 at 7:30
