The Interplanetary Overlay Network (ION) software distribution is an implementation of Delay-Tolerant Networking (DTN) architecture as described in Internet RFC 4838. It includes implementations of the DTN Bundle Protocol, the Licklider Transmission Protocol, and two CCSDS application protocols that have been adapted to run over the BP/LTP stack: the CCSDS File Delivery Protocol and Asynchronous Message Service.
otonat is a 1:1 NAT implementation for FreeBSD. Unlike other solutions that keep state for individual user connections even for 1:1 NAT, otonat is completely stateless as far as user connections are concerned. This allows it to scale much better and provide protection against misbehaving clients that may consume a lot of server memory by opening too many connections.
Lyra is a front-end to the Music Player Daemon (MPD). Based loosely on the Creative Media Source software, it has the aim of supporting large collections of albums and artists. Other interesting features are the implementation of a local cache of the music library using an SQLite database, increased speed, and flexibility. In addition, Lyra supports integration with the Last.fm service, which includes "Scrobbling" and album cover art.
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.
dhcpcd-gtk is a GTK+ monitor for dhcpcd. It uses dhcpcd-dbus to talk to dhcpcd and wpa_supplicant. At present, dhcpcd-gtk is just an application that sits in the notification area. The icon has several states, showing offline, address negotiation, and online. When attempting to negotiate an address, you get a nice animation. A notification bubble is also shown per interface state change. Future versions will have Access Point selection and dhcpcd configuration options.
