Question

Remove the warning when we enable SSH on an ESXI host

Answer 1

SSH error

By default in an ESXi Host when we enable SSH we see a yellow triangle in the Host icon and the text "Configuration Issues SSH for the host has been enabled" in the Summary tab.

That warning indicates that something is not right. The fact of having the SSH service open for both management tasks and automation and / or monitoring in a controlled manner should not " tarnish " the view of our Hosts.

Let's see how to remove the warning of an ESXi Host when we have the SSH service enabled. In the Hosts and Clusters inventory view, we select the Host to configure. We click on the Configuration tab and at the Software level (see image) we click on Advanced Settings.

In the Advanced Settings window we select UserVars . In the window on the right, in the UserVars.SuppressShellWarning section, we change the 0 to a 1.

Then click on "OK" the Advanced Settings window will close and we can check that the warning has disappeared.

We must bear in mind that if we do not use the SSH service in a continuous and controlled manner we are leaving open a door for a possible attack on our Host. It is possible to configure the ESXi 5 firewall to filter and control from which network / networks or Host / s it is possible to access the SSH service of our Host.
