20.1. 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).
Steps:
Configure with DAG support:
./configure --enable-dag --prefix=/usr --sysconfdir=/etc --localstatedir=/var
make
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
