Description Retlaw Dlawso 2010-01-03 16:36:43 UTC 
Summary:

SELinux is preventing /usr/sbin/snort-plain "module_request" access.

Detailed Description:

[SELinux is in permissive mode. This access was not denied.]

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.

Allowing Access:

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

Comment 1 Daniel Walsh 2010-01-04 15:18:55 UTC 
You can add these rules for now using

# grep avc /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp

Since I have added all available "snort" packages for fedora 12 Constantine 
with package manager for gnome, gpk-application 2.28.3, everything works
perfectly since 2010-01-17.
SELinux troubleshoot browser showed not a sole alert.
