Hi all, I should also mention that I tested this issue with the newest version of Snort. However, I had to send the packet (with invalid sequence and ack numbers) repeatedly 3 times (to Snort) before Snort passed one of the packets down to the detection engine ( I wrote a rule to check this) Thanks, On Tue, Apr 8, 2008 at 2:12 AM, tung tran <tunghack () gmail com> wrote:
Hi all, My question is: "is is true that even though Stream5 preprocessor is on (with necessary directives set), Snort always passes a packet down to the detection engine even though the packet has invalid sequence number/ acknowledge number which is not expected by the receiver and the packet is normally discarded by the receiver ?". Is there a way to tell Snort not to passes packets with invalid sequence/acknowledge numbers down to the detection engine? I tested this with the newest version of Snort. Thanks, Tung.
