OpenWrt
A Linux operating system targeting embedded devices
OpenWrt Project is a Linux operating system targeting embedded devices. Instead of trying to create a single, static firmware, OpenWrt provides a fully writable filesystem with package management. This frees you from the application selection and configuration provided by the vendor and allows you to customize the device through the use of packages to suit any application. For developers, OpenWrt is the framework to build an application without having to build a complete firmware around it; for users this means the ability for full customization, to use the device in ways never envisioned. -

FancySS
fancyss is a project for bypassing the Great Firewall (GFW)
Fancyss is a “scientific Internet access / bypassing censorship” toolkit targeted principally to Asus routers running AsusWRT or Merlin-based firmware. The project provides a plugin suite (with “software center” integration) so that home routers can run proxy or tunneling tools (e.g. V2Ray) to circumvent firewall or censorship (“GFW” in the Chinese context). Because it integrates into the router’s firmware environment, fancyss automates configuration, routing, and firewall rules to minimize manual tinkering. It supports multiple architectures and firmware versions, though some submodules or variants (e.g. “fancyss_hnd”) are optimized for specific chipsets. The project also maintains offline packages for constrained environments and hardware support lists. Many users adopt fancyss to turn relatively cheap consumer routers into censorship-resilient gateways, avoiding separate proxy appliances. -

Open Source Routing Machine
Open Source Routing Machine - C++ backend
High-performance routing engine written in C++14 designed to run on OpenStreetMap data. There are several services available via HTTP API, C++ library interface and NodeJs wrapper. Nearest, snaps coordinates to the street network and returns the nearest matches. Route finds the fastest route between coordinates. Table computes the duration or distances of the fastest route between all pairs of supplied coordinates. Match snaps noisy GPS traces to the road network in the most plausible way. Trip solves the Traveling Salesman Problem using a greedy heuristic. Tile generates Mapbox Vector Tiles with internal routing metadata. To quickly try OSRM use our demo server which comes with both the backend and a frontend on top. The easiest and quickest way to setup your own routing engine is to use Docker images we provide. We base our Docker images (backend, frontend) on Debian and make sure they are as lightweight as possible. -

FlowViewer
FlowViewer is a web-based netflow data analysis tool.
FlowViewer provides a convenient web-based user interface to Mark Fullmer’s flow-tools suite and CMU's netflow data capture/analyzer, SiLK. The inclusion of the underlying SiLK tool set enables FlowViewer users to continue to use the tool with the newer IPFIX netflow data protocol, which includes support for IPv6 and Cisco's v9 and FNF netflow. FlowViewer has been developed for NASA’s Earth Sciences Data and Information System (ESDIS) networks, and credit goes to NASA for their usual outstanding support of innovation. The FlowViewer tools provide additional graphing and tracking features by utilizing open source software including Thomas Boutrell’s gd, Lincoln Stein's GD, Martien Verbruggen's GD::Graph, and Tobias Oetiker’s RRDtool. FlowViewer v4.6 fixes non-UTC local time environments for FlowViewer and FlowGrapher, and $no_devices_or_exporters FlowMonitor_Collector problem. **Note: SiLK must be v3.8.0 or later. Version 3.9 handles sFlow data. -

KeexyBox
The box to keep the Internet under your control
KeexyBox allows you to do parental control, block ads, limit telemetry, and browse the Internet anonymously from your home network without installing any software on your devices. It also can be used to create a public wireless access point with the captive portal. It is a software program which requires a Raspberry PI box and which is installed on Raspbian. It constitutes a cut-off point between your devices (computers, tablets, smartphones, etc.) and your router or Internet box. KeexyBox acts as a default gateway and DNS server for the devices in your home network. It thus intercepts all connections to the Internet to carry out website filtering or to activate browsing via the Tor anonymity network according to connection profiles which you have configured. -

frr
This is a non-official VM of FRRouting (FRR)
FRRouting (FRR) is an IP routing protocol suite for Linux and Unix platforms which includes protocol daemons for BGP, IS-IS, LDP, OSPF, PIM, and RIP. FRR’s seamless integration with the native Linux/Unix IP networking stacks makes it applicable to a wide variety of use cases including connecting hosts/VMs/containers to the network, advertising network services, LAN switching and routing, Internet access routers, and Internet peering. FRR has its roots in the Quagga project. In fact, it was started by many long-time Quagga developers who combined their efforts to improve on Quagga's well-established foundation in order to create the best routing protocol stack available. We invite you to participate in the FRRouting community and help shape the future of networking. This is not an official release from the FRRouting Project. Credentials: frradmin / frr -
