Troubleshooting

Missing /run/user/1000

Using a mosh session, $XDG_RUNTIME_DIR (/run/user/1000) doesn't exist and causes issues such as:

  • nix-shell failing with Error in tempdir() using /run/user/1000/nix-shell.XXXXX

This is caused by the way mosh handles logging-in to the system, the login is actually handled by a short ssh session, which ends immediately. logind, as it is used, closes the user's session and cleans up behind, since there is no lingering configured by default.

To enable lingering use:

$ loginctl enable-linger $USER

Then reconnect with mosh.

As a workaround, it is also possible to set an alias in the user's shell on the server wrapping mosh-server to keep the session around. [1]

alias mosh-server = "systemd-run --user --scope mosh-server"

See https://github.com/NixOS/nixpkgs/issues/3702#issue-40762878 for alternative option
