Re: All tcp ports open?

I saw this too on a linux/router/FW using iptables TARPIT module. http://www.securityfocus.com/infocus/1723 But that succed if you are scannig in a HALF way (SYN flag). If there is some kind of Honeypot then a daemon (in this case "service") it must to make a response to a full tcp connection. (i.e.: banner response commands interaction, etc.) GUs.-
I am not sure what is doing this, but I assume it is a software (or some kind of) firewall/hids, can anybody point me in the right direction? 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. --------------------------------------------------------------------------
