PacketQ

packetq is a command line tool to run SQL queries directly on PCAP files, the results can be outputted as JSON (default), formatted/compact CSV and XML. It also contain a very simplistic web-server in order to inspect PCAP files remotely. PacketQ was previously known as DNS2db but was renamed in 2011 when it was rebuilt and could handle protocols other than DNS among other things.

More information is provided in our FAQ, functions, and fields documentation.

A short demo-video of PacketQ's capabilities is available on http://www.youtube.com/watch?v=70wJmWZE9tY

Features

• Super-fast native decoding of PCAP-files (even gzipped) and dirt-quick in-memory sorting algorithms.
• A extensible protocol decoding design with build in support for ICMP and DNS from start.
• Support for grouping, sorting, counting and most other important SQL-functions.
• Only dependent on zlib, no other hard-to-find libs needed. Compiles on everything.
• Build-in web-server, JSON API and a simple JQuery-based GUI concept application with graphs.
• Can be designed to cache queries by pre-processing PCAPs into static JSON-files that can be used to make queries again.
• Built in DNS-resolver function (used by GUI).
• Support for sampling. Helps when making queries to large, uniform PCAP-files.
• Can convert flags in packet-headers to text on the fly.
• Can make multiple queries towards the same data in memory.

Dependencies

PacketQ requires a couple of libraries beside a normal C++ compiling environment with autoconf, automake, libtool and pkgconfig.

PacketQ has an optional dependency on the MaxMindDB library (for the CC() and ASN() functions).

To install the dependencies under Debian/Ubuntu:

apt-get install -y zlib1g-dev libmaxminddb-dev

To install the dependencies under CentOS (with EPEL enabled):

yum install -y zlib-devel libmaxminddb-devel

Build from GitHub

git clone https://github.com/DNS-OARC/PacketQ.git
cd PacketQ
./autogen.sh
./configure [options]
make
make install

Building from source tarball

The source tarball from DNS-OARC comes prepared with configure:

tar zxvf packetq-version.tar.gz
cd packetq-version
./configure [options]
make
make install

Usage example

Retrieves the 10 first packets containing DNS information from the file sample.pcap:

packetq -s "select * from dns limit 10" sample.pcap

Starts a web-server on port 8080 (-p8080) as a daemon (-d) serving files from the directory html/ (-w html/) and PCAP files from the directory pcap/ (-r pcap/):

packetq -d -p8080 -w html/ -r pcap/
