Libpcap when built for DAG cards against dag-2.5.1 or later releases: Timeouts are supported. pcap_dispatch() will return after to_ms milliseconds regardless of how many packets are received.
http://www.opensource.apple.com/source/libpcap/libpcap-18/libpcap/README.dag
Building libpcap at this stage will include support for both the native packet capture stream (linux or bpf) and for capturing from DAG cards. To build libpcap with only DAG support specify the capture type as 'dag' when configuring libpcap: ./configure --with-dag=DIR --with-pcap=dag Applications built with libpcap configured in this way will only detect DAG cards and will not capture from the native OS …

The DAG support has been implemented as a new packet capture type with a pcap-dag.c along the lines of the existing capture types. Libpcap will be built with the DAG capture type if configured with '--with-pcap=dag --with-dag=DIR'; the latter option being to give configure a hint where to find the DAG support files for inclusion in the library.

How to compile Suricata with DAG support Overview Endace DAG™ (Data Acquisition and Generation) Data Capture Cards are the ultimate in dedicated network packet capture interface cards. They guarantee 100% packet capture on any network regardless of packet size, interface type, or network load. Endace DAG cards are designed for capturing ...

Endace's DAG libraries are at 3.0.0 now, and crucially they now support linux kernels >= 2.6.18. However, the libpcap configure script fails to work properly because the object file names now have "libdag_la" in front. This patch fixes the configure script to properly locate the needed object files.

With libpcap 0.9.2 or later on Linux, if libpcap has been built with support for the DAG API from Endace Measurement Systems, it should be possible to capture SS7 traffic with DAG cards from Endace. Capturing with Septel or NetStructure SS7 cards from Intel

If the dag3 port was built with libpcap support, you can also use any libpcap based application to capture packets from the dag card e.g. tcpdump -ni dag0-w dump.pcap. The DAG cards are built with inline forwarding ap-plications in mind. As such, they are equipped with hardware fail-safe relays which automatically turn the DAG ports into an electrical passthrough in the event of a machine malfunction.

If you want to build WinPcap with the support for the CACE Technologies AirPcap wireless capture library, you will need to download the AirPcap developer's pack from http://www.cacetech.com/downloads.html. The AirPcap developer's pack needs to be unzipped in the same folder where the WinPcap sources have been unzipped.

Mar 06, 2017 · Linux has a number of BPF based systems, and libpcap does not support any of the eBPF mechanisms as yet, although it supports many of the memory mapped receive mechanisms. See the README.linux file for more information.
