A scan of localhost on one of my boxes using 2.6.10 (with no active packet
filtering) reveals:
Running: Linux 2.4.X|2.5.X|2.6.X
OS details: Linux 2.5.25 - 2.6.3 or Gentoo 1.2 Linux 2.4.19 rc1-rc7)
Uptime 3.573 days (since Mon Jan 3 04:41:25 2005)
TCP Sequence Prediction: Class=random positive increments
Difficulty=1061991 (Good luck!)
IPID Sequence Generation: All zeros
