What are iptables policies?
What will be an ideal response?
The policy decides what happens to a packet that did not match a rule in the chain. The policy could either be to accept the packet or to drop it.

To set the policy, use the -P option:

(Enhancing Class Rectangle) Create a more sophisticated Rectangle class than the one you created in Exercise 9.20. This class stores only the Cartesian coordinates of the four corners of the rectangle. The constructor calls a set function that accepts four sets of coordinates and verifies that each of these is in the first quadrant with no single x- or y-coordinate larger than 20.0. The set
func- tion also verifies that the supplied coordinates do, in fact, specify a rectangle. Provide member func- tions that calculate the length, width, perimeter and area. The length is the larger of the two dimensions. Include a predicate function square that determines whether the rectangle is a square. What will be an ideal response?
