Distributed reverse / forward proxy and tunneling solution for TCP.
PortFusion is a minimalistic, cross-platform, transport-layer distributed reverse / forward proxy for TCP written in Haskell + LLVM and released under GPLv3. A single package that makes the most of each platform by tapping into their unique capabilities, combining this power with an intuitive interface, beautiful design and Haskell's excellent support for unprecedented levels of concurrency and parallelism. It strives for the smallest source code size (< 500 lines) while delivering maximum throughput with near zero overhead.
C++ exception (and generic) stack trace library (now libinstrument)
Project is migrating to libinstrument (https://sourceforge.net/projects/libinstrument/) Libcsdbg is a C++ exception stack tracer, offers the tools to create and process exception traces, the path an exception has propagated up the call stack, unwinding it, up to the point where it was handled. The traces are detailed with demangled function signatures and addr2line info (source file and line of each function call). Libcsdbg will perform flawlessly with multi-threaded programs, with dynamically linked shared objects (DSO) and with any statically linked library. Libcsdbg helps the developer/tester also create stack traces of any thread, at any point during, as a snapshot of the runtime call graph. This is very useful in cases of fatal errors, reception of terminating signals or process abortion/termination (such as segmentation faults)
Wraith is an open source IRC bot written in C++. It has been in development since late 2003. It is based on Eggdrop 1.6.12 but has since evolved into something much different at its core.
A multi-platform universal log collector and forwarder
NXLog is a modular, multi-threaded, high-performance log management solution with multi-platform support. In concept it is similar to syslog-ng or rsyslog but is not limited to unix/syslog only. It can collect logs from files in various formats, receive logs from the network remotely over UDP, TCP or TLS/SSL . It supports platform specific sources such as the Windows Eventlog, Linux kernel logs, Android logs, local syslog etc. Writing and reading logs to/from databases is also supported. The collected logs can be stored into files, databases or forwarded to a remote log server using various protocols. The old BSD Syslog and the newer IETF syslog standard is fully supported by NXLog in addition to Snare, XML, JSON, GELF, KVP, CSV and custom formats. A key concept in NXLog is to be able to handle and preserve structured logs. No need to convert everything to syslog and parse these logs again at the other side. It has powerful message filtering, log rewrite and conversion capabilities.

Microsoft Exchange compatible server and client libraries
OpenChange is a portable Open Source implementation of Microsoft Exchange server and Exchange protocols. It provides a complete solution to interoperate with Microsoft Outlook clients or Microsoft Exchange servers. OpenChange client-side library is used in existing messaging clients and is the solution in new projects to communicate natively with Microsoft Exchange and Exchange-compatible servers. OpenChange server is a transparent Microsoft Exchange server replacement using native Exchange protocols and does not require any plugin installation in Outlook.
The program thrulay is used to measure the capacity, delay, and other performance metrics of a network by sending a bulk TCP or UDP stream over it.
Pen is a load balancer for udp and tcp based protocols.
This is Pen, a load balancer for udp and tcp based protocols such as dns, http or smtp. It allows several servers to appear as one to the outside and automatically detects servers that are down and distributes clients among the available servers. This gives high availability and scalable performance.
