sec-wall is a feature-packed security proxy that supports SSL/TLS, WS-Security, HTTP Auth Basic/Digest, extensible authentication schemes based on custom HTTP headers and XPath expressions, powerful URL matching/rewriting, and an optional header enrichment. It's a security wall with which you can conveniently fence otherwise defenseless backend servers.
Aftpd is an FTP server for anonymous access designed for Unix-like operating systems. It uses an asynchronous model of connection processing and provides service for all users within a single process; can use multiple threads to run more efficiently on multi-core systems, with each thread serving multiple clients simultaneously; uses effective mechanisms of transferring files, minimizing copying of data in RAM (sendfile or a combination of the system calls mmap/writev); uses effective event notification schemes (kqueue on FreeBSD and epoll on Linux); uses poll or select in older systems; and supports IPv6. For safety, it works as an unprivileged user and uses chroot.
The goal of Funani is to solve the management of large image and other media collections in a practical way. To help you find the data you want in big data collections, this software allows you to sort it in many different ways. Advanced queries on dates, locations, events, or people, or more generically categories and tags, allow you to narrow the search quickly. Funani can be thought of primarily as a safe. Every file put into the system remains in the system. It is an additive system, which makes unintended deletion impossible. A maintenance mode can still remove unwanted files, but standard users cannot perform this operation. Funani is also a framework designed for extensibility. When new features are requested, they can be implemented by adding new functionality and leaving the existing system alone. Each feature is completely isolated from others as long as it does not depend on them.
Mail2Web is a gateway between email and Web service for places where no direct Internet connection is available, but email can be used. This script can be installed in the .forward file of an email-enabled Unix account and will then translate simple email commands into Web page fetches. Authorized users are identified by their "from" address and a password in the subject line.
