21.1. Endace DAG

Suricata comes with native Endace DAG card support. This means Suricata can use the libdag interface directly, instead of a libpcap wrapper (which should also work).


Configure with DAG support:

./configure --enable-dag --prefix=/usr --sysconfdir=/etc --localstatedir=/var
sudo make install

Results in:

Suricata Configuration:
  AF_PACKET support:                       no
  PF_RING support:                         no
  NFQueue support:                         no
  IPFW support:                            no
  DAG enabled:                             yes
  Napatech enabled:                        no

Start with:

suricata -c suricata.yaml --dag 0:0
