You said "Are there any other rules you have defined? If no, this may work:"
To me, that means that if the user does not have any other rules, then he
should try these (the ones you posted).
I just wanted to avoid the original poster trying out a ruleset which could
not possibly work (and if they were connected to the machine by SSH, would
cut them off permanently, too).
