JS-Collider is an event-driven Java network NIO framework. It is designed to provide maximum performance and scalability for applications having not too many connections but significant amounts of network traffic (both incoming and outgoing). Performance and scalability are achieved via lock free algorithms and atomic states usage. It supports UDP (with multicast) as well. One of the implementation points is to avoid unsafe cheating; it should work the same way on all JVMs (Java 1.7). It supports shared memory IPC.
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).
The Barefoot server is a scalable user-space port bouncer that can be used to forward, or bounce, TCP connections and UDP packets destined for an address on the host on which the Barefoot server runs to any other host or address. To these other hosts, it will appear as if the connection and packets are coming from the machine on which the Barefoot server runs, rather than from the original host. The Barefoot server has support for using proxy protocols on the outgoing side, and can relay incoming traffic out via a SOCKS server or an HTTP proxy supporting the CONNECT command. At the moment, using a proxy for outgoing traffic is only supported for the TCP protocol. The Barefoot server is targeted towards larger sites that need to bounce traffic from many simultaneous clients, while at the same time offering detailed access control, logging, and other features related to controlling the behavior of the traffic and the Barefoot server.
Opsview Core is a network monitoring software application. It solves the challenges of monitoring modern IT and network systems. It is a drop-in replacement for Nagios Core, with full support for its plugins and 100% compatibility. It is easy to install and configure and is ideal for monitoring applications networks, and Windows, Linux, and Unix servers. VMWare, KVM, Xen, and Microsoft Hyper-V are supported, and Amazon EC2 and other cloud services can be monitored. It works with Opsview Mobile to allow you to monitor your systems on the go.
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.
USB Network Gate (former USB to Ethernet Connector) easily connects one or more remote USB devices to your computer over Ethernet (Internet/LAN/WAN) as if the device was plugged into your own machine. It helps you share a USB device over Ethernet among multiple computers so people from all over the world (or your office) can use it. By intercepting the USB port activity of a shared USB device and redirecting it via TCP/IP,USB Network Gate lets you access your printer, scanner, Web cam, USB dongle, or any other supported USB device from your home PC or office laptop. Just plug the device in and it will automatically appear on the remote side of the connection. You can secure your USB data by enabling traffic encryption and access your USB devices remotely via WiFi.
trx is a toolset for broadcasting live audio from Linux. It sends and receives encoded audio over IP networks, via a soundcard or audio interface, and can be used for point-to-point audio links or multicast (e.g., private transmitter links or audio distribution). High-quality wideband audio (such as music) can be sent with low latency and fast recovery from dropouts.
