Description

Hi experts!!!

I am new in suricata, so firstly I want say Hello!!.
I have configured Suricat 2.0.1 with pf_ring 5.6.1. I want use snuri to capture HTTP POST which are forwarded to my system. I have problem with configuration the output unified2-alert to store the reassembled packets. When size of HTTP POST is larger then 1500, I can see in my unified2 file that every tcp segemnt is stored as event and packet, so if HTTP POST consist of 2 tcp segments I have 2 events and 2 packets, from my point of view would be better to have only one event and packet for reassembled packet. My question is: is it possible to configure in suricata 2.0.1 output with unified2-alert to store reassembled packets ??

No, this is not possible. In the future there will be a log method to log the entire http headers, http body and such. But that won't use unified2.

In this development code branch, there is a new option to log the payloads in json: https://github.com/inliniac/suricata/pull/991 It also logs the stream, in a single buffer. Perhaps you can help test it.

Hi Victor, I think this entry cause core dump:

- eve-log:
      enabled: yes
      filetype: file #file|syslog|unix_dgram|unix_stream
In suricata.log I can see:

30/6/2014 -- 12:19:01 - <Error> - [ERRCODE: SC_ERR_INVALID_YAML_CONF_ENTRY(139)] - Invalid entry for eve-log.type. Expected "regular" (default), "unix_stream", "pcie" or "unix_dgram"

When I change it on:

- eve-log:
      enabled: yes
      type: file #file|syslog|unix_dgram|unix_stream

suricata is running but logging of payload dosen't work...
Can You advise me what is wrong with my suricata ??

Is this still an issue as we released 3.0 and the json output advanced/improved a lot?
So if not we can close it :)
