[aefmaaradji]

Bonjour,

et j'ai

rpm -Uv snort-2.8.0.2-1.FC7.i386.rpm
rpm -Uv snort-mysql-2.8.0.2-1.FC7.i386.rpm

comment faire pour installé les régles de snort et démaré le NIDS snort

Merci

Salut,

L'installation se passe-t-elle sans problème ?

bonjour,
j'ai refait l'instalation avec snort-2.8.1

#rpm -Uv snort-2.8.1-1.FC7.i386.rpm

le snort marche dans le cas de sniffing (il capture le traffic réseau) quand je fait

# snort -v

mais quand j'ai fait le mode IDS ne marche pas or

# snort -A full -c snort.conf

il affiche: sa

Running in IDS mode
