CloudVPN is a secure decentralized mesh networking tool. It allows applications to use it as a mesh transport layer for packet routing, easily creating mesh ethernet VPN, secured audio/video broadcasting or communication channels, etc. It can create secured networks with special or weird topologies, so it's very easy to create connection schemes with clustered/decentralized servers, topologies with better throughput, ring-like topologies for failover, long-line for passing through many routes, or tree topology for optimizing inter-server bandwidth needs.
Wiremaps is an application that gathers layer 2 wiring information on a network using protocols like LLDP, EDP, CDP, and SONMP. It also gathers information from the FDB (MAC-port table on switches), the ARP table (MAC-IP table), and some miscellaneous information like interface names.
netsniff-ng is a high performance Linux network sniffer for packet inspection. It is similar to analyzers like tcpdump, but without the need to perform system calls for fetching network packets. A memory-mapped area within kernelspace will be used for accessing packets, so there is no requirement for copying them to userspace (a 'zero-copy' mechanism). For this purpose, netsniff-ng is libpcap independent, but nevertheless supports the pcap file format for capturing, replaying, and performing offline analysis of pcap dumps. The project is focused on building a robust, clean, and secure analyzer and utilities that complete netsniff-ng as a support for penetration testing. netsniff-ng can be used for protocol analysis, reverse engineering, and network debugging.
pingspray is a tool that generates network traffic for EMC (electromagnetic compatibility) tests. It can generate both random and periodic patterns of data as suggested in some EMC standards. It uses ICMP echo requests (ping) to generate traffic, and when it works as intended, it will generate traffic in both directions.
