A script which does exactly what you desrcibe is mentioned in the book "hacking: the art of exploitation" by jon erickson only on a linux machine. the basic idea is something like: use tcpdump to monitor all incoming SYN packets not destined for any listening service and then use a packet generation tool (such as nemsis) to generate a packet with a seq#+1 and the SYN and ACK flags set.
Are you saying that the specific script that implements this will only work on a Linux machine, or are you saying that the idea described is only applicable on a Linux machine? FWIW, the idea should work on pretty much any machine capable of sniffing and spoofing, ie, everything but XP SP2. -- Cory ------------------------------------------------------------------------------ Ethical Hacking at the InfoSec Institute.
