Re: Snort 3 Config File Question (3)

Problems. While Snort is happy with the new Rules file it is also keeping me from doing anything useful on the internet. Also, the packets it is logging to the Unified2 log are strange. For example:

(Event)
sensor id: 0 event id: 133 event second: 1500926568 event microsecond: 248613
        sig id: 412     gen id: 116     revision: 1 classification: 29
priority: 3 ip source: 0.0.0.0 ip destination: 255.255.255.255 src port: 68 dest port: 67 ip_proto: 17 impact_flag: 0 blocked: 0
        mpls label: 0   vlan id: 0      policy id: 0    appid:

Packet
        sensor id: 0    event id: 133   event second: 1500926568
        packet second: 1500926568       packet microsecond: 248613
        linktype: 1     packet_length: 342

I'm not accustomed to this format and my Ethernet tap is broken. Until I get the parts I have on order to build a new tap so I can get Wireshark on the job I'm going to have to work on other things. Once I have the new tap built I will put Snort back online and share what I find.
