Hello, When comparing nmap -O output for my FreeBSD server (4.3RC4) and a Linux machine (2.4), there are significant differences in their tcp sequence prediction difficulties. FreeBSD only had on the order of 15,000 - 20,000, while Linux had 3,000,000 - 5,000,000. I saw that the security advisory FreeBSD-SA-00:52.tcp-iss.asc was an attempt to strengthen the randomness of this. Did it help? What is going on with the large differences? Is this a problem at all? Thanks very much. Hope I got the right list.
