Landscape LDS - Remove Computer(s)

Question

I have an installation of Landscape LDS 15.11 on 14.04 and have a couple of computers that I would like to remove. I have tried 'Remove computer' from within the computer properties but nothing happens. I have also removed the license and then tried to 'Remove computer' and same result.

Has anyone else experienced this issue or have a workaround for it?

Answer 1

Turns out that I had an issue with RabbitMQ. The landscape-appserver was unable to authenticate to RabbitMQ. Once I resolved this, I was able to remove the machines without issue.

Answer 2

From what I found :

cd /var/log/rabbitmq/
tail -f rabbit@landscape.log (or different name perhaps on your server)

Check the error message:

*=ERROR REPORT==== 11-May-2018::12:04:32 ===
closing AMQP connection <0.2798.0> (127.0.0.1:53570 -> 127.0.0.1:5672):
{handshake_error,starting,0,
                 {amqp_error,access_refused,
                             "AMQPLAIN login refused: user 'landscape' - invalid credentials",
                             'connection.start_ok'}}*

If this is the problem follow these instructions:

less /opt/canonical/landscape/configs/standalone/service.conf

Check section [broker]

Copy the password string part after the b64:

Use base64 decoder (here's an online one) or you can use

base64 -d <<< "paste the coded string here"

Execute the command

rabbitmqctl change_password <user> <password>

Check rabbitmq logfile again and check if computer is removed

Hope this helps!

According to Landscape docs, you should do these tasks:

1. Remove the landscape-client package from the registered machine (did you do this? you didn't mention in your question.)
2. In Landscape, select the machine(s) you want to remove and click on "Info", so that you get to the info page
3. There, just below the comment box, is a link called "Remove this computer...". Click on it and confirm the action
