Is port 8080 within your stream and http preprocessors?

Can you share the pcap?

Subject: [Snort-users] Snort 2.9.13 not recognizing server response in PCAP.

Hi,

I have a situation where snort does not appear to be recognizing packets that I have in a PCAP. The packet in question is a simple HTTP server response. The rule is setup to read content in the packet.

The server port is 8080. At this point, I can not figure out which configuration setting to change to get snort to parse the server response.

Sample Rule:
alert tcp any any -> any any \
( \
 msg: "Alert"; \
flow:from_server,established; \
content:"password"; \
sid:6000002; rev:1; \
)


Thanks.
