AUC (Authenticated User Community) is an intranet system designed for use in an educational organization but is also useful in many other settings. It offers the ability for users to have a uniform web-based interface to discussion forums, e-mail (similar to hotmail, etc.), file management, and a searchable user database. Also, "Interactive Classrooms" provide a means for students and teachers to have a web-based extension to their in-class interaction. The system runs from a C-based monolithic CGI script. MySQL is used for database storage. Also, the web-based mail client supports MIME parts/attachments, IMAP, mbox, and multiple mail folders.
Authforce is an HTTP authentication brute forcer. Using various methods, it attempts brute force username and password pairs for a site. It has the ability to try common usernames and passwords, username derivations, and common username/password pairs. It is used both to test the security of your site and to highlight the insecurity of HTTP authentication due to the fact that users just don't pick good passwords.
authlocal is a simple, self-contained program module (Just one file, just one function to call from your code) to automatically authenticate users logging into servers from localhost. No username/password entry is required. authlocal has been tested to work under versions 2.0 - 2.4 of the Linux kernel.
auto nice daemon activates itself in certain intervals, and renices jobs according to their priority, and CPU usage. Jobs owned by root are left alone. Jobs are never increased in their priority. It is very flexible. The renice intervals can be adjusted, as well as the default nice level, and the activation intervals. A priority database stores user/group/job tuples along with their renice values for three CPU usage time ranges. The strategy for searching the priority database can be configured. Linux, OpenBSD, FreeBSD, Digital UNIX, Solaris, and IRIX are supported.
