I've seen any scan from some cable providers (comcast in particular) exhibit this behavior. On Sun, 29 Aug 2004 18:36:18 -0400, Varun Pitale <varun.pitale () gmail com> wrote:
I have seen a solaris box which was acting as a load balancer act this way too, so it might be a loadbalancer thing. All ports seem to be open, but they do not give any response . If you could post what kinds of machines they are, it would be good..

I am pen-testing a Windows webserver, and a port scan reveals ALL tcp ports open. hping also confirms that a SA is returned for any S packets sent to any port I try. I can connect via netcat any of the ports, and send data, but nothing is returned. In order to verify services, I am required to connect and check for a banner or send appropriate protocol commands to elicit a response. Has anyone seen this, or have any idea of what this is?
