:SELinux is preventing snort from 'create' accesses on the netlink_socket .
:*****  Plugin catchall (100. confidence) suggests  ***************************
:If you believe that snort should be allowed create access on the  netlink_socket by default.
:Then you should report this as a bug.
:You can generate a local policy module to allow this access.
:allow this access for now by executing:
:# grep snort /var/log/audit/audit.log | audit2allow -M mypol
:# semodule -i mypol.pp

Comment 1 Miroslav Grepl 2012-06-12 10:09:32 UTC
Could you please execute

# semanage permissive -a snort_t

which will make snort_t domain as permissive and re-test it and then execute

# ausearch -m avc -ts recent

which will get us AVC msgs. Thank you.
