HP-UX tcp_random_seq

[aleph1 () DFW NET (Aleph One)]

I dont belive this is been given enough distribution. Under HP-UX you can
configure it to use random TCP sequence numbers by setting the
tcp_random_seq variable. The values are:

   0 - old behavior (default)
   1 - rand(3) bahavior
   2 - rand48(3) behhavior

The seed value for the rand*() functions is based on the time when
tcp_init() (or nettune) is called, so dont make your uptime public
(i.e. rstatd).

Under 10.X use nettune to set tcp_random_seq. Under 9.X you will have to
use the debuger, and then reboot.

   echo "tcp_random_seq?W 2" | adb -w /hp-ux
