ESXi 5: Suppressing the local/remote shell warning
Using the SSH shell is a pretty efficient way to get things done on ESXi 5.x, but annoyingly it is disabled by default. Enabling the ESXi shell is simple enough to do.
But having enabled it means vSphere will show a warning message ESXi shell for the host has been enabled and in the host view the host is shown with a yellow warning exclamation mark. If you’re like me you’ll want to enable the shell but not have the warning always showing.
Suppressing the warning is pretty straightforward. In the vSphere client select the affected host and then click the configuration tab. Open up Advanced Settings and click UserVars from the menu tree and scroll all the way down to the UserVars.SuppressShellWarning setting. Change the value from 0 to 1.
