the problem is you aren't flooding, you are just sending the data, also there is no use for normal users to have access to ping , chmod 700 ping, and you are all set On Mon, 14 Aug 2000, Slawek wrote:
Hello, I'm not sure if it's new informations, but as far as I can see it works at least on most of current systems (worked everywhere I could test it). The problem is: -s parameter of ping command has no upper limit for normal users. This allows normal users to send for example 1 * 60000 bytes of ICMP data per second (from one copy of ping invoked) I think it's just great for DoSing ;o) Bye, Slawek
