At the console, hit "Alt-F1" to get the first console (you are on the second, by default):
Give the root password to log in.
You should get a shell prompt with warning:
Uncomment the "ssh" line & save the file.
Find the PID of inetd & HUP it so that the changes take care:
kill -HUP 1234
SSH is enabled from now, feel free to use it for monitoring, scripting etc..
