Flowgrind is a tool similar to iperf or netperf. It measures throughput and other metrics for TCP and other protocols. It features some unique characteristics: a distributed architecture, sophisticated flow scheduling, Linux kernel TCP statistics, the Anderson-Darling statistical test, rate-limited flows with uniform or Poisson distribution, and separation between control and test traffic.
PacketDam is a cost-effective software solution against DDoS. It runs on off-the-shelf hardware and fits any budget or deployment scenario.

Ripcord is an PHP 5 XML-RPC server and client library with a very simple and easy to use API. You can create XML-RPC, (simplified) SOAP 1.1, and SimpleRPC clients with one call and then call RPC methods as if they were local methods of the client. You can create a server with one call, passing it any number of objects or classes whose methods it will publish and automatically document.
NiftyName is a system for creating and managing virtual machine pools and all related components such as storage, private and public networks. It is intended to be used as a free alternative to Amazon EC2 and Microsoft Azure. All components have been designed for multi-site active redundancy, though this is not supported yet. Its architecture is based on documented XML-RPC (SSL) Web services, so you can make your own derivative tools for it. Console and GTK+ client applications are provided. VMs are based on KVM. It supports IPv6, private VLANs, multiple interfaces, user/client management, permissions, and roles.
