[c-nsp] Xwindow session timeout through Pix Firewall

[lee.e.rian at census.gov]

Well then, how about adjusting it on the other side?
Change the tcp keepalive interval from 2 hours to 20 minutes on the HP and
see if that works:

ndd -set /dev/tcp tcp_keepalive_interval 1200000

(not sure about the syntax, I don't have root on any HP machines)
