Description Michal Kilijanek 2019-06-23 16:32:09 UTC
Description of problem:
I started system and seen alert in SELinux. I don't know what caused this issue. 
I had this alert twice before and after first time I have run commands: 
# ausearch -c 'snort' --raw | audit2allow -M my-snort
# semodule -X 300 -i my-snort.pp

But situation occurs again and again. 
SELinux is preventing snort from 'create' accesses on the netlink_netfilter_socket Nieznane.

*****  Plugin catchall (100. confidence) suggests   **************************

Aby snort powinno mieć domyślnie create dostęp do Nieznane netlink_netfilter_socket.
Then proszę to zgłosić jako błąd.
Można utworzyć lokalny moduł polityki, aby umożliwić ten dostęp.
Do
można tymczasowo zezwolić na ten dostęp wykonując polecenia:
# ausearch -c 'snort' --raw | audit2allow -M my-snort
# semodule -X 300 -i my-snort.pp
