The problem here is that the "if..." is not inside an event handler.
The user manual might be a bit confusing here: this code is just an
excerpt of how to make use of the allow_services table but it does
not work on its own. Take a look at the head of the function
check_hot() in hot.bro to see how this works in larger context.
(check_hot() is in turn called from various event handlers such as
connection_established() in conn.bro).
