Your opinion.  I still haven't seen anything in this thread (that hasn't been
refuted) that suggest that PARANOID checks provide any more security than
leaving a box wide open.  Yet, there is plenty of proof that they cause
problems (if you don't believe me, do a GOOGLE search for "tcpd paranoid
problem")

You're the one changing the subject, not me.

Every system should be relying on "*explicitly specified* IP's", whether the
IP specified is 0.0.0.0/0 or 127.0.0.1.  Not bullshit "security" like 
PARANOID.  If you could swallow your pride for a second, stop saying things
like "REAL security", and think about what this check actually does, you would
see exactly how silly it is.
