Re: Open Letter to D-Link about their NTP vandalism

To keep this operational: Operationally the network operator should
contact a lawyer before doing something like this.
Purposely and knowingly sending bad data in order to do harm is a
counter-attack. As such it might be vigilantism, which is illegal in
most countries. Or it might be self-defense, which is not illegal.
Might. Contact a lawyer.

I've said in other forums the only solution for this sort of software is
to return the wrong time (by several months). The owner might actually
notice then and fix the problem.
Just not returning anything means the time still works on the querying
device (especially if it uses multiple servers) and the problem will not
be noticed and it will continue.
