North American Network Operators Group Date Prev | Date Next | Date Index | Thread Index | Author Index | Historical Re: Open Letter to D-Link about their NTP vandalism
It's legal to have broken NTP server in ANY country, and it's legal in most (by number) countries to send counter-attack (except USA as usual, where lawyers want to get their money and so do not allow people to self-defence). So, it can be a GOOD prtactice in reality. But, of course, not in USA. ----- Original Message ----- From: "John Dupuy" <[email protected]> To: <[email protected]> Sent: Tuesday, April 11, 2006 9:00 AM Subject: 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.
