-Key Based Authentication
-========================
+.. seealso:: SSH :ref:`ssh_key_based_authentication`
-It is highly recommended to use SSH Key authentication. By default there is
-only one user (``vyos``), and you can assign any number of keys to that user.
-You can generate a ssh key with the ``ssh-keygen`` command on your local
-machine, which will (by default) save it as ``~/.ssh/id_rsa.pub``.
-
-Every SSH key comes in three parts:
-
-``ssh-rsa AAAAB3NzaC1yc2EAAAABAA...VBD5lKwEWB username@host.example.com``
-
-Only the type (``ssh-rsa``) and the key (``AAAB3N...``) are used. Note that the
-key will usually be several hundred characters long, and you will need to copy
-and paste it. Some terminal emulators may accidentally split this over several
-lines. Be attentive when you paste it that it only pastes as a single line.
-The third part is simply an identifier, and is for your own reference.
-
-.. cfgcmd:: set system login user '<username>' authentication public-keys '<identifier>' key '<key>'
-
-Assign the SSH public key portion `<key>` identified by per-key `<identifier>`
-to the local user `<username>`.
-
-.. cfgcmd:: set system login user '<username>' authentication public-keys '<identifier>' type '<type>'
-
-Every SSH public key portion referenced by `<identifier>` requires the
-configuration of the `<type>` of public-key used. This type can be any of:
-
-* ``ecdsa-sha2-nistp256``
-* ``ecdsa-sha2-nistp384``
-* ``ecdsa-sha2-nistp521``
-* ``ssh-dss``
-* ``ssh-ed25519``
-* ``ssh-rsa``
-
-.. note:: You can assign multiple keys to the same user by using a unique
- identifier per SSH key.

RADIUS
======
-VyOS supports using one or more RADIUS servers as backend for user authentication.
+In large deployments it is not reasonable to configure each user individually
+on every system. VyOS supports using :abbr:`RADIUS (Remote Authentication
+Dial-In User Service)` servers as backend for user authentication.
-The following command sets up two servers for RADIUS authentication, one with a
-discrete timeout of `5` seconds and a discrete port of `1812` and the other using
-a default timeout and port.
+Configuration
+-------------
-.. code-block:: none
+.. cfgcmd:: set system login radius server '<address>' secret '<secret>'
- set system login radius server 192.168.1.2 secret 's3cr3t0815'
- set system login radius server 192.168.1.2 timeout '5'
- set system login radius server 192.168.1.2 port '1812'
- set system login radius server 192.168.1.3 secret 's3cr3t0816'
+ Specify the `<address>` of the RADIUS server user with the pre-shared-secret
+ given in `<secret>`. Multiple servers can be specified.
-This configuration results in:
+.. cfgcmd:: set system login radius server '<address>' port '<port>'
-.. code-block:: none
+ Configure the discrete port under which the RADIUS server can be reached.
+ This defaults to 1812.
+
+.. cfgcmd:: set system login radius server '<address>' timeout '<timeout>'
- show system login
- radius {
- server 192.168.1.2 {
- secret s3cr3t0815
- timeout 5
- port 1812
- }
- server 192.168.1.3 {
- secret s3cr3t0816
- }
- }
-
-.. note:: If you wan't to have admin users to authenticate via RADIUS it is
+ Setup the `<timeout>` in seconds when querying the RADIUS server.
+
+.. hint:: If you wan't to have admin users to authenticate via RADIUS it is
essential to sent the ``Cisco-AV-Pair shell:priv-lvl=15`` attribute. Without
the attribute you will only get regular, non privilegued, system users.
-Source Address
---------------
-RADIUS servers could be hardened by only allowing certain IP addresses to connect.
-As of this the source address of each RADIUS query can be configured. If this is
-not set incoming connections to the RADIUS server will use the nearest interface
-address pointing towards the RADIUS server - making it error prone on e.g. OSPF
-networks when a link fails.

============
-You are able to set post-login or pre-login messages with the following lines:
+You are able to set post-login or pre-login banner messages to display certain
+information for this system.
-.. code-block:: none
+.. cfgcmd:: set system login banner pre-login '<message>'
+
+ Configure `<message>` which is shown during SSH connect and before a user is
+ logged in.
+
+.. cfgcmd:: set system login banner post-login '<message>'
- set system login banner pre-login "UNAUTHORIZED USE OF THIS SYSTEM IS PROHIBITED\n"
- set system login banner post-login "Welcome to VyOS"
+ Configure `<message>` which is shown after user has logged in to the system.
-**\\n** create a newline.
+.. note:: To create a new line in your login message you need to escape the new
+ line character by using ``\\n``.
