Enable SSH ESXi
From MS Computech
By default this isn’t possible. But there’s a way to get this working, just do the following:
Go to the ESXi console and press alt+F1
Type: unsupported
Enter the root password
At the prompt type “vi /etc/inetd.conf”
Look for the line that starts with “#ssh” (you can search with pressing “/”)
Remove the “#” (press the “x” if the cursor is on the character)
Save “/etc/inetd.conf” by typing “:wq!”
Restart the management service “/sbin/services.sh restart”
