pks-commands.php3 allows your Web server to search and add PGP/GPG keys from the public keys out there. It takes the TCP 11371 port connection and does it all on the web server. It is good in environments where the client machines are unable to get to arbitrary TCP ports (such as behind tightened firewalls).
Yafig is a LAMP-based firewall rule generator that creates shell scripts for use with Linux netfilter/iptables. The user interface is similar to the FireWall-1 policy editor. Its main features are Web-based host, network, and service management. support for multiple policies with individual password protection, shared objects for multiple policies, support for chains (default and custom), and architecture independence.
Easy Firewall Generator is a PHP Web application that generates an iptables firewall script. The generated script is designed for a single system connected to the Internet or a system acting as a gateway/firewall for a small private network. The generator prompts recursively for a variety of options. When the selected options form a complete set, it generates and returns a commented firewall script based on those options. The generator includes documentation on iptables and each option.
IPTables log analyzer displays Linux 2.4 iptables logs (rejected, accepted, and masqueraded packets) in a nice HTML page. The reports it produces are easy to read and understand, reducing the manual analysis time. They contain statistics on packets and links to more detailed information on a given host, port, or domain.
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.
LAN Management System (LMS) is a set of database-driven applications capable of managing multiple networks of computers and customers. It uses a Web UI and either a multipurpose daemon written in C or a set of Perl scripts that perform scheduled tasks and configure your system services. It was designed to organize small self-financed networks, but is mature enough to suit the needs of medium sized ISPs. Support for multiple databases and languages are included, and a template system allows it to blend in with your existing infrastructure.
m0n0wall is an all-in-one firewall software package that is based on FreeBSD. It is geared towards embedded PCs, but it also works on standard PCs. It includes an easy-to-use Web interface like commercial firewall boxes do. PHP is used instead of shell scripts, and the entire system configuration is stored in a single XML-formatted file. There is support for VPN, traffic shaping, captive portal, VLANs, and more.
