Point was not so much Windows, but the end result of what Steve Gibson talks
about and that should be a concern to anyone running a website on an AS/400 if
some body and knock you off the net... :-)

<2) Having said that, OS/400 has had support for raw sockets (and I've used
them!) since at least V3R2.  The UNIXes have had it since sockets & TCP/IP were
invented.>

True, but again, not the point. The truly concerning thing is all of these
Windows home users getting always on high speed connections and leaving this 
MASS
volume of machines open to be exploited this way...

3) If you say that there is no valid reason for raw sockets, and that the
addition of this protocol makes Windows PC's secure, this will naturally imply
that UNIX and OS/400 were already less secure than Windows.   A laughable
statement.>

I didn't say that - I'm not smart enough to have a clue about that stuff :-) 
That
was Steve Gibson's statement.

<This whole topic is just silly.>

We will see... I hope you are right ! The shear volume of traffic these folks
threw at GRC.COM was INCREDIBLE and very few folks could handle anything like
that (and he DID have a firewall).

No offense but again, I think this would be of concern and relevance to anyone
hosting a website on an AS/400, uh, iSeries :-)
