	~~{{expansion\|Missing installation~~ and configuration of both server and ~~client~~.}}		[https://mosh.org/ Mosh] is an alternative SSH terminal. It has support for roaming, local echo and uses UDP for transport. It also aims to improve responsiveness on intermittent, and high latency connections.

			See the [https://search.nixos.org/packages?show=mosh&query=mosh mosh Package] and [https://search.nixos.org/options?query=programs.mosh mosh Options]

			== Instalation ==

			=== Client ===

			Install the <code>[https://search.nixos.org/packages?show=mosh&query=mosh mosh]</code> package.

			=== Server ===

			Enable the <code>[https://search.nixos.org/options?query=programs.mosh programs.mosh]</code> module. You can simply add the following into your <code>/etc/nixos/configuration.nix</code>:

			<syntaxhighlight lang=nix>
			# Enable mosh, the ssh alternative when client has bad connection
			# Opens UDP ports 60000 ... 61000
			programs.mosh.enable = true;
			</syntaxhighlight>

			== Usage ==

			With mosh installed on both the client and server, connect by running:

			<syntaxhighlight lang=console>
			$ mosh user@server
			</syntaxhighlight>

			Note that mosh uses SSH for authentication and initialization, so it will respect aliases and other options in <code>.ssh/config</code>. You can also specify SSH options using the <code>--ssh</code> argument. For example, to use port 1122 instead of 22, you can either use <code>Port 1122</code> in SSH config, or use mosh with the <code>--ssh</code> argument:

			<syntaxhighlight lang=console>
			$ mosh --ssh='ssh -p 1122' user@server
			</syntaxhighlight>

			More information is available at [https://mosh.org/#usage mosh.org] or using <code>[https://manpages.debian.org/bullseye/mosh/mosh.1.en.html man mosh]</code>

			=== The locale requested by LANG=*** isn't available here. ===

			This error occurs when trying to connect to a linux server (non-NixOS distribution) on which mosh-server has been installed via nix. The easy solution is to set LOCALE_ARCHIVE to your OS locale-archive in your .profile or .zshenv:

			<syntaxhighlight lang=bash>
			export LOCALE_ARCHIVE=/usr/lib/locale/locale-archive

== Troubleshooting ==

=== Missing <code>/run/user/1000</code> ===

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

* nix-shell failing with <code>Error in tempdir() using /run/user/1000/nix-shell.XXXXX</code>

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

As a workaround, it is possible to set an alias in the user's shell wrapping <code>mosh-server</code> to keep the session around.<ref>[https://botbot.me/freenode/nixos/2017-12-20/?msg=94859441&page=1 #nixos 2017-12-20]</ref>
