Nulog is a PHP interface for the MySQL plugin for the ulogd netfilter log daemon and for NuFW SQL logging (optional). It displays hosts (or users) that recently broke packets on your firewall and the last ports that were probed. A simple search function allows packets to be searched by host or by a given port. Nulog was formerly known as ulogd-php.
NuFW is an authenticating firewall. It adds strict and secure identity-based filtering capabilities to enterprise-grade firewalls. It can also set quality of service on a per-user basis and log user activities into an SQL database. Furthermore, it can use multiple external authentication sources via PAM and be the key of a Single Sign On solution.
NuFW.Live is a live CD based on knoppix. This is the simplest way to test the authenticating firewall NuFW and its associated tools. NuFW.Live features all NuFW's related software. It includes identity-based filtering rules to Netfilter, Nulog 2, a powerful firewall log analysis Web interface, Nuface 2, an ACL management interface, and pyctd, a Netfilter connection tracking display and modification interface.
