there is a README.flexresp in source directory that will explain all the functions of flexresp. -----Original Message----- From: snort-users-admin () lists sourceforge net [mailto:snort-users-admin () lists sourceforge net]On Behalf Of Ramin Alidousti Sent: Tuesday, August 28, 2001 01:30 PM To: snort-users () lists sourceforge net Subject: [Snort-users] flexresp Hello, I'm a snort newbie so please be gentle. Q: Is it possible to send a reset for a tcp connection to both sides. Let me elaborate. Client C (external) connects to server S (internal). During the monitoring the conversation between these two, snort realizes that C is trying to do something nasty. As I understand it, flexresp can be triggered to tear down the connection by resetting the connection on the client side; but what happens is that the server remains in an ESTABLISHED state. Now, if C does this for, let's say, 1000 times, as you can see the resources on S are being consumed for nothing. Actually, what I'm more interested in is sending an RST to the server and let the client hang for a while (which I don't care). Besides, having torn down the connection on S, the consequent packets from C will cause an RST from S anyway. Is there any way to tell snort to protect S and send an RST to it? Thanks for any help/pointer.
