Copy Landscape SSL CA certificate to Clients

Registration of the client systems requires Landscape server’s SSL public key for authenticity. The Landscape quickstart package generates and installs a self-signed SSL certificate in /etc/ssl/certs/landscape_server_ca.crt using the FQDN of the host for the commonName field of the certificate.

Hence, copy this certificate file to every client and place it under an appropriate directory, say /etc/landscape/, for example;

scp /etc/ssl/certs/landscape_server_ca.crt [email protected]:/etc/landscape/

Install Landscape Client

In order to manage Ubuntu systems using Landscape, you need to register them as Landscape clients. Hence, login to the Ubuntu systems you need to manage from Landscape dashboard and install Landscape client package to allow you register Ubuntu systems.

Update your system packages and install Landscape client.

sudo apt update
sudo apt install landscape-client

Register the computer

Next, proceed to register the client Ubuntu systems you need to manage from Landscape dashboard by executing the command below;

sudo landscape-config --computer-title "Server01" --account-name standalone  --url https://u18server.example.com/message-system --ping-url http://u18server.example.com/ping --ssl-public-key /etc/landscape/landscape_server_ca.crt

You will be prompted to provide a few details about the client computer and the Landscape account.

The Landscape client must be started on boot to operate correctly.

Start Landscape client on boot? [Y/n]: y 

This script will interactively set up the Landscape client. It will
ask you a few questions about this computer and your Landscape
account, and will submit that information to the Landscape server.
After this computer is registered it will need to be approved by an
account administrator on the pending computers page.

Please see https://landscape.canonical.com for more information.


A registration key may be associated with your Landscape
account to prevent unauthorized registration attempts.  This
is not your personal login password.  It is optional, and unless
explicitly set on the server, it may be skipped here.

If you don't remember the registration key you can find it
at https://landscape.canonical.com/account/standalone

Account registration key: Access Key
Please confirm: Access Key

The Landscape client communicates with the server over HTTP and
HTTPS.  If your network requires you to use a proxy to access HTTP
and/or HTTPS web sites, please provide the address of these
proxies now.  If you don't use a proxy, leave these fields empty.

HTTP proxy URL: Enter
HTTPS proxy URL: Enter

Landscape has a feature which enables administrators to run
arbitrary scripts on machines under their control. By default this
feature is disabled in the client, disallowing any arbitrary script
execution. If enabled, the set of users that scripts may run as is
also configurable.

Enable script execution? [y/N]: y

By default, scripts are restricted to the 'landscape' and
'nobody' users. Please enter a comma-delimited list of users
that scripts will be restricted to. To allow scripts to be run
by any user, enter "ALL".
