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.

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.
