Working with SSH

-Whenever the `leap` command nees to push changes to a node or gather information from a node, it tunnels this command over SSH. Another way to put this: the security of your servers rests entirely on SSH. Because of this, it is important that you understand how `leap` uses SSH.

SSH and local nodes

2. `leap` entirely skips the checking of host keys when connecting with a local node.
3. `leap` adds the public Vagrant SSH key to the list of SSH keys for a user. The public Vagrant SSH key is a shared and insecure key that has root access to most Vagrant virtual machines.
+To upgrade a SSH host key
+-------------------------------

+Most servers will have more than one SSH host key. Sometimes, the server will have a better SSH host key than the one you have on file. In order to upgrade to the better SSH host key, simply re-run the init command:

+This will prompt you if you want to upgrade the SSH host key, but only if `leap` thinks that an upgrade is advisable.

+To see details about the keys and certs you can use `leap inspect` like so:

+Let's Encrypt certificate
+=========================
+
+LEAP plans to integrate [Let's Encrypt](https://letsencrypt.org/) support, so it will be even easier to receive X.509 certificates that are accepted by all browsers.
+Until we achieve this, here's a guide how to do this manually.
+
+Install the official acme client
+--------------------------------
+
+Log in to your webapp node
+
+ server$ git clone https://github.com/letsencrypt/letsencrypt
+ server$ cd letsencrypt
+ server$ ./letsencrypt-auto --help
+
+Fetch cert
+----------
+
+Stop apache so the letsencrypt client can bind to port 80:
+
+ server$ systemctl stop apache2
+
+Fetch the certs
+
+ server$ ./letsencrypt-auto certonly --standalone --email admin@$(hostname -d) -d $(hostname -d) -d api.$(hostname -d) -d $(hostname -f) -d nicknym.$(hostname -d)
+
+This will put the certs and keys into `/etc/letsencrypt/live/DOMAIN/`.
+
+Now, go to your workstation's provider configuration directory and copy the newly created files from the server to your local config. You will override existing files so please make a backup before proceeding, or use a version control system to track changes.
+
+ workstation$ cd PATH_TO_PROVIDER_CONFIG
+
+Copy the Certificate
+
+ workstation$ scp root@SERVER:/etc/letsencrypt/live/DOMAIN/cert.pem files/cert/dev.pixelated-project.org.crt
+
+Copy the private key
+
+ workstation$ scp root@SERVER:/etc/letsencrypt/live/DOMAIN/privkey.pem files/cert/DOMAIN.key
+
+Copy the CA chain cert
+
+ workstation$ scp root@SERVER:/etc/letsencrypt/live/DOMAIN/fullchain.pem files/cert/DOMAIN.key
+
+Deploy the certs
+----------------
+
+Now you only need to deploy the certs
+
+ workstation$ leap deploy
+
+This will put them into the right locations which are:
+
+- `/etc/x509/certs/leap_commercial.crt` for the certificate
+- `/etc/x509/./keys/leap_commercial.key` for the private key
+- `/usr/local/share/ca-certificates/leap_commercial_ca.crt` for the CA chain cert.
+
+Start apache2 again
+
+ server$ systemctl start apache2
