Résumé:

SELinux is preventing /usr/sbin/snort-plain "read" access on dev.

Description détaillée:

[SELinux est en mode permissif. Cet accès n'a pas été refusé.]

SELinux denied access requested by snort. It is not expected that this access is
required by snort and this access may signal an intrusion attempt. It is also
possible that the specific version or configuration of the application is
causing it to require additional access.

Autoriser l'accès:

You can generate a local policy module to allow this access - see FAQ
(http://docs.fedoraproject.org/selinux-faq-fc5/#id2961385) Please file a bug
report.
