             Summary: Index not working when traffic encapsulated in 802.1q trunk
                 Key: TM-16
                 URL: https://bro-tracker.atlassian.net/browse/TM-16
             Project: Time Machine
          Issue Type: Problem
    Affects Versions: git/master
         Environment: Ubuntu 10.04 , pf_ring
            Reporter: tyler.schoenke


Hi All,

When I query the time machine index, I am not receiving any results.

I just restarted time machine, and checked one of the recent class files to see there is traffic for a particular IP address.

tcpdump -e -v -n -r class_all_1385406639.023206 "vlan and host 128.138.44.198"

It shows some traffic, example:
    128.138.44.198.54014 > 74.125.225.209.443: Flags [.], cksum 0x8d2c (correct), seq 1283940799:1283940800, ack 615539104, win 16311, length 1
19:11:00.571731632 10:8c:cf:57:46:00 > 00:1d:09:6a:d9:a9, ethertype 802.1Q (0x8100), length 70: vlan 987, p 0, ethertype IPv4, (tos 0x0, ttl 56, id 17482, offset 0, flags [none], proto TCP (6), length 52)

When I telnet localhost 42042 and run the following command, I don't receive any results.

query to_file "128.138.44.198.pcap" index ip "128.138.44.198"

In the above tcpdump, you can see my traffic is 802.1Q trunked.  I have to use the "vlan" BPF to extract it with tcpdump, and am wondering if the trunking is causing problems with indexing?   

I tested the same version of time machine on non-trunked traffic, and the index works fine.

Let me know if you need any other configuration info.
