Must admit there comes a time when you need to enable SSH on an ESXi host and i for one find navigating the GUI a bit time consuming and to be honest not really necessary.

To that matter using good old PowerCLI we can enable ssh on a host with a very simple command line

1
Get-VMHost HostName | Get-VMHostService | Where Key -EQ "TSM-SSH" | Start-VMhostService

And then once we are finished its good practise to disable SSH once again.

1
Get-VMHost HostName | Get-VMHostService | Where Key -EQ "TSM-SSH" | Stop-VMHostService -Confirm:$False
