mountebank - Over the wire test doubles

•    HTML

---

In fact, halfway through we discovered our corporate mocking software couldn’t handle the sheer amount of performance testing we were running as part of this effort (we completely crushed some pretty industrial enterprise software in the process). As a result, we made the call to move the entire program over to a Mountebank OSS-based solution with a custom provision to give us the ability to expand/shrink our mocking needs on demand. mountebank is the first open source tool to provide cross-platform, multi-protocol test doubles over the wire. Just point your application to mountebank instead of the real dependency, and test like you would with traditional stubs and mocks.

chisel - A fast TCP tunnel over HTTP

•    Go

---

Chisel is a fast TCP tunnel, transported over HTTP, secured via SSH. Single executable including both client and server. Written in Go (Golang). Chisel is mainly useful for passing through firewalls, though it can also be used to provide a secure endpoint into your network. Chisel is very similar to crowbar though achieves much higher performance.

socket.io - Realtime application framework (Node.JS server)

•    Javascript

---

For this purpose, it relies on Engine.IO, which first establishes a long-polling connection, then tries to upgrade to better transports that are "tested" on the side, like WebSocket. Please see the Goals section for more information. Unless instructed otherwise a disconnected client will try to reconnect forever, until the server is available again. Please see the available reconnection options here.

A standalone build of socket.io-client is exposed automatically by the socket.io server as /socket.io/socket.io.js. Alternatively you can serve the file socket.io.js found in the dist folder. A slim build (without JSON3, a JSON polyfill for IE6/IE7, and debug) is also available: socket.io.slim.js.

udp2raw-tunnel - A Tunnel which Turns UDP Traffic into Encrypted UDP/FakeTCP/ICMP Traffic by using Raw Socket,helps you Bypass UDP FireWalls(or Unstable UDP Environment)

•    C++

A Tunnel which turns UDP Traffic into Encrypted FakeTCP/UDP/ICMP Traffic by using Raw Socket, helps you Bypass UDP FireWalls(or Unstable UDP Environment). It can defend Replay-Attack and supports Multiplexing. It also acts as a Connection Stabilizer. When used alone,udp2raw tunnels only UDP traffic. Nevertheless,if you used udp2raw + any UDP-based VPN together,you can tunnel any traffic(include TCP/UDP/ICMP),currently OpenVPN/L2TP/ShadowVPN and tinyfecVPN are confirmed to be supported.

proximac - An open-source alternative to proxifier

•    C

---

I am re-writing a GUI based Proximac using my own network framework. Come and check out my socket framework. Proximac is an command-line open-source alternative to Proxifier. With Proximac, it can force App to use SOCKS5 proxy. In the other words, it can forward any App's traffic to a certain SOCKS5 proxy. Moreover, Proximac now can forward all network traffic in your system to a proxy which means you may not need a VPN to do this job. I hope more developers can join this project.

zsocket - Zero-copy sockets for Linux in Golang

•    Go

---

ZSocket is a library that wraps the linux zero-copy socket syscall to create a ring buffer in a memory mapped file. It also contains some utility functions and types to help with a handful of layer 2, 3, and 4 types. It is a lot like libcap, except it has easy to understand facilities for writing (injecting packets) to an interface. ZSocket doesn't contain or wrap any C/C++, and it is lock free and thread safe.
