I'd like to avoid writing a program to exploit this > and testing it several hundred times here to get a figure. write a program to send out SYN's and get back SYN+ACK's and record them, or just record a bunch of SYN+ACK responses from your host to other hosts along with a timestamp. Now take those recorded numbers and see if you can predict the next value given the previous N values and timestamps and the next timestamp. tcpdump can get you sequence numbers and timestamps. > Leo Bicknell - bicknell@vt.edu | Make a little birdhouse > bicknell@csugrad.cs.vt.edu | in your soul...... > bicknell@ussenterprise.async.vt.edu | They Might
