New page

Allegedly, VMware Cloud Director has MQTT capabilities.
This seems like a bit of an excess to add in a simple little set of tools...

OTOH... Adding MQTT clients to a small management VM & using SSH to run them is an option.

I've created a VM named '''Skeeter''' with a user named '''skeeter'''.

Skeeter has <code>openssh-server</code> & <code>mosquitto-clients</code> installed.

Skeeter also has <code>mosquitto</code> installed for testing purposes.

So...

Open an SSH session to '''Skeeter''' & subscribe to a topic:
* <code>mosquitto_sub -h localhost -t "mqtt" -v</code>

Then send a publish to '''Skeeter''' using '''ssh''':
* <code>ssh skeeter@skeeter "mosquitto_pub -h localhost -t 'mqtt' -m 'Hello MQTT'"</code>

You'll see "'''mqtt Hello MQTT'''" appear in the SSH session.

'''w00t!'''

Next trick... Set up [[passwordless SSH]] from the '''ESXi''' server to '''Skeeter'''.
