    Ping Bombs

    Hello,

    My friends and I were messing around one night with some DOS net programs and something that cought my eye was the "ping" programs parameters. I took notice that one would be able to tweak the packet size and the TTL variable.

    I guess my question is: Would it be possible to send like say 5000 echo requests with like , 3000 bytes of data in each request. If so, what would happen on the receiving end?

    It is possible to do that to screw with someone's computer: it's an old Denial of Service (DoS) attack, that would take down computers running on early versions of Win95 (and some other OS's). It's been fixed for all new versions of Windows and there are patches for the old versions. Not sure about other platforms though.

    It's been fixed for just about all the OS platforms

    I think we used to call that the Ping-O-Death

    Pretty much every OS out there has been patched for this though.

    C:\WINDOWS>ping -l 4000 65.58.199.254

    Pinging 65.58.199.254 with 4000 bytes of data:

    Reply from 65.58.199.254: bytes=4000 time=44ms TTL=128
    Reply from 65.58.199.254: bytes=4000 time=20ms TTL=128
    Reply from 65.58.199.254: bytes=4000 time=6ms TTL=128
    Reply from 65.58.199.254: bytes=4000 time=20ms TTL=128

    Ping statistics for 65.58.199.254:
    Packets: Sent = 3,000 Received = 3,000 Lost = 0 (0% loss)
    Approximate round trip times in milli-seconds:
    Minimum = 3ms, Maximum = 34ms, Average = 22ms


    I think we used to call that the Ping-O-Death
    When pinged with a packet greater than 65,536 bytes Microsoft Windows 95,98 will sometimes crash. 65,536 is illegal!
