Help

Hi

I have a problem when I setup Suricata version 4.x and 5.x. The model I use is the NIDS.

I have successfully configured the span port and the IDS machine can receive the traffic

When using tcpmdump I can see the http protocol logs (tcpdump -i ens1 -n port 80).

But when I create the rule to test the content is

alert http any any -> $ HOME_NET any (msg: "HUNGHAY HTTP_TEST";)

Logs http protocol are not found in eve.json and fast.log.

Can you guys help me handle this problem.

Thanks
