conexus is a generalized C++ I/O library that includes network support for IPv4 and IPv6 sockets, serial/TTY communications, kernel message queues, pipes, and files. Objects use sigc++ for signaling property changes and other information. Sub-libraries include conexus-gtkmm (provides a set of gtkmm widgets), conexus-dbus (provides dbus support for endpoints), conexus-nspr (provides NSPR endpoints), conexus-nss (provides NSS endpoints), and conexus-ssl (provides OpenSSL endpoints).
qpimd aims to implement a PIM (Protocol Independent Multicast) daemon for the Quagga Routing Suite. Initially, it targets only PIM SSM (Source-Specific Multicast) mode as defined in section 4.8.2 (PIM-SSM-Only Routers) of RFC 4601. In order to deliver end-to-end multicast routing control plane, qpimd includes the router-side of IGMPv3 (RFC 3376).
The Resilient Streaming Protocol (RSP) is a one-way IP/UDP media streaming protocol that was developed to provide high reliability audio streaming between the mountainchill.com Internet radio station's rural studios and SHOUTcast servers. Although the protocol operates in a unidirectional fashion (without listener ack/resend packets), it does support optional listener reporting and packet quality tracking. A streaming server called rspServer is included. It accepts multiple RSP stream sources, providing both RSP and SHOUTcast compatible relaying and transcoding. The source code package also includes a command-line encoder and decoders.
hwmultd is a daemon which, when run in server mode, periodically polls some hardware device, like an entropy source, and multicasts that information. Alternatively, hwmultd can run in client mode, listening for multicasted information and then acting accordingly, like adding gathered entropy to the local pool. Its simple plugin system allows hwmultd to be agnostic with respect to the hardware, which could include devices such as temperature probes or time sources.
DVBlast is a simple and powerful MPEG-2 transport stream demux and streaming application with several input methods, such as Linux DVB supported cards (DVB-S, DVB-S2, DVB-C, DVB-T, etc.), ASI cards, and UDP/RTP streams carrying a transport stream. It outputs one or several UDP/RTP streams carrying transport streams with hardware or software PID filtering, PID-based or service-based demultiplexing, and optional descrambling via a CAM device.
dhcpy6d delivers IPv6 addresses for DHCPv6 clients, which can be identified by DUID, hostname, or MAC address, as in the good old IPv4 days. Addresses may be generated randomly, by range, or by arbitrary ID or MAC address. Clients can get more than one address, leases and client configuration can be stored in databases, and DNS can be updated dynamically.
