We have more than 500 systems running ubuntu in our office. And sometimes after installation we forget to enable to Remote desktop. So that we was not able to control that PC remotely. Is there any way to access that machine remotely using SSH? Coz ssh was installed in that remote machine. Also if that machine was in login screen we was not able to view through vnc. I guess SSH will be a good solution. Can anyone help me? Thanks in advance.
