A modular plugin architecture provides stdio, cons, and evdev user interfaces, celt, g711, g722, gsm, ilbc, l16, and speex audio codecs, alsa, coreaudio, gst, portaudio, oss, winwav, and mda audio drivers, speex_pp, speex_aec, speex_resamp, and sndfile audio filters, the avcodec video codec, avformat, quicktime, qtcapture, v4l, and v4l2 video sources, sdl, opengl, and x11 video display drivers, and srtp media encoding.
restund is a modular STUN/TURN server that is designed around the principle of a lightweight core and server modules that extend its functionality. Both UDP and TCP are supported, along with IPv6 and IPv4. Supported modules include STUN, TURN, MySQL database, syslog, and status monitoring.
NetCrack is cluster software developed to distribute a hashing algorithm's cracking process work using a brute force attack. Currently, it only supports the two most commonly used hashing algorithms: MD5 and SHA-1. Support is included for MySQL, safe mode, and others. It works like a client/server application, where the server is unique for each cluster network and its job is to distribute the cracking process work, coordinate the nodes, and prevent connections and data integrity errors.
Serv-U is a powerful and easy-to-use file server which supports the FTP, HTTP, and SFTP (via SSH2) protocols to ensure maximum compatibility with the widest range of transfer client software. It supports SSL encryption, provides a Web-based interface to allow administrators to remotely access and configure the file server, includes a built-in transfer client to allow users to upload and download files from their Web browsers, provides photo sharing capabilities, integrates with Active Directory (providing levels of security based on Organizational Units), and can be accessed and administered in 13 different languages simply by choosing an appropriate language upon login.
