OpenSSH Server on Debian / Ubuntu / Raspbian
- Stefan Paetow

Neither Debian nor Ubuntu ship with a version of OpenSSH that is compatible with Moonshot. To get Moonshot support for it, you must install a specific Moonshot-enabled version. We have a precompiled version available in our repositories.
Contents
All of the instructions below assume that you have root access, and will work as the root user (either directly or using sudo).
The instructions on this page will replace the system provided OpenSSH packages with the Moonshot enabled ones (don't worry, standard SSH things will still work!).
Following the instructions on this page will give you a Moonshot-enabled OpenSSH Server only.
1. System Preparation
1.1. Add the Moonshot libraries.
If you have not already done so, you first need to follow the instructions on how to Install Moonshot Libraries on a Debian/Ubuntu/Raspbian Server.
1.2. Enable the Moonshot OpenSSH Repository
The OpenSSH packages have their own dedicated repository, to avoid replacing system's one when not strictly required.
This repository needs to be manually enabled, by editing the /etc/apt/sources.list.d/moonshot.list file and uncommenting the following line, where $OS is the code name of your Debian-based distribution (you do not need to provide, it will be there).
... # moonshot SSH repository deb http://repository.project-moonshot.org/debian-moonshot $OS openssh ...
... # moonshot SSH repository deb http://repository.project-moonshot.org/raspbian $OS openssh ...
1.3. Ensure that your hostname is correct
The channel bindings check requires that the hostname of your SSH server match the hostname people are SSHing to. That is, the output of the hostname and hostname -f commands should match the FQDN of the server. If it doesn't, change /etc/hostname to make it so.
2. Installation Instructions
Install the Moonshot-enabled pre-compiled OpenSSH packages using apt. This will replace the system provided OpenSSH.
apt-get install ssh openssh-server
3. Configuration Instructions
Once installed, the Moonshot-enabled OpenSSH server will still need a few quick tweaks in order to turn on the Moonshot support.
Follow the configuration instructions on the OpenSSH Server page to configure the server.
