Socat is a relay for bidirectional data transfer between two independent data channels. Each of these data channels may be a file, pipe, device (terminal or modem, etc.), socket (Unix, IP4, IP6 - raw, UDP, TCP), SSL, a client for SOCKS4, or proxy CONNECT. It supports broadcasts and multicasts, abstract Unix sockets, Linux tun/tap, GNU readline, and PTYs. It provides forking, logging, and dumping and different modes for interprocess communication. Many options are available for tuning socat and its channels. Socat can be used, for example, as a TCP relay (one-shot or daemon), as a daemon-based socksifier, as a shell interface to Unix sockets, as an IP6 relay, or for redirecting TCP-oriented programs to a serial line.
Artekopia Netjuke is a cross-platform Web-based audio streaming jukebox powered by PHP 4 and an increasing choice of databases. MP3, Ogg Vorbis, ASF/WMA, and other music file formats are supported. Artekopia Netjuke aims to enable small organizations or communities run a private "mp3.com-like" Web site to access the music they legitimately own, distribute, or are granted access to. It supports most audio players, language packs, optional file downloads, media protection schemes, multi-level security, shared and private playlists, random playlists, images, etc. It also features an unusual, easy-to-use installer module to get you started in minutes.
Kismet is an 802.11 layer 2 wireless network detector, sniffer, and intrusion detection system. It will work with any wireless card which supports raw monitoring (rfmon) mode, and can sniff 802.11b, 802.11a, 802.11g, and 802.11n traffic (device drivers permitting). It identifies networks by passively collecting packets and detecting standard named networks, detecting (and given time, decloaking) hidden networks, and inferring the presence of non-beaconing networks via data traffic.
