I've seen any scan from some cable providers (comcast in particular)
exhibit this behavior.

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 not sure what is doing this, but I assume it is a software (or some

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?
Thanks.
