Homer is a free cross-platform SIP softphone with video support.
Homer is a free cross-platform SIP softphone with video support. The Homer software is able to communicate in peer-to-peer mode without any infra- structure. But it also supports SIP servers (PBX boxes) as well. The amount of participants per live video conferences is not limited by the software. Besides the conference functions, Homer can also be used for video/audio streaming, recording and screencasting. Video as well as audio data from files or hardware devices can be streamed to every conference participant individually. Additionally, video/audio streams can be started as separate unicast transmissions to any host in the local network or the Internet with quality settings ranging from very low to very high (HDTV). Such streams can be received by Homer and can again be recorded to disc and made available for offline playback. Source code: https://github.com/Homer-Conferencing/Homer-Conferencing

Network steganography / covert channels evaluation tool
Encryption is not sufficient to secure communication because often the simple fact that communication exists is often enough to raise suspicion and take further actions. Covert channels aim to hide the very existence of communication by using means of communication not normally intended to be used. The Covert Channels Evaluation Framework (CCHEF) is a flexible software framework for empirically evaluating network steganography methods or covert channels in network protocols. CCHEF can be used in real networks with real overt traffic (e.g in research testbeds), but can also simulate covert channels using overt traffic from trace files (e.g. evaluation on a single host). CCHEF is designed for evaluating covert channels and not for (mis)using them for actual covert communication. CCHEF's sender or receiver are normal user space applications that are not disguised in any way and do not contain any malware-like code, e.g. they do not illegally acquire superuser privileges etc.
An IRC(u) services server framework written in C++. This server framework is capable of supporting as many individual clients as the protocol supports. Each client can be custom made by subclassing an existing fully functioning client.
