Zmap - The Internet Scanner

---

ZMap is an open-source network scanner that enables researchers to easily perform Internet-wide network studies. With a single machine and a well provisioned network uplink, ZMap is capable of performing a complete scan of the IPv4 address space in under 45 minutes, approaching the theoretical limit of gigabit Ethernet. ZMap can be used to study protocol adoption over time, monitor service availability, and help us better understand large systems distributed across the Internet.

IoTSeeker - Created by Jin Qian via the GitHub Connector

---

This scanner will scan a network for specific types of IoT devices to detect if they are using the default, factory set credentials. The recent Internet outage has been attributed to use the IoT devices (CCTV Cameras, DVRs and others) with default credentials. It's the intention of this tool to help organizations scan their networks to detect these types of IoT devices and to identify whether credentials have been changed or if the device is still using the factory setting. Note that Mirai malware, suspected to have been used to launch the massive internet outage on Oct 21, 2016, mainly focuses on telnet services. IoTSeeker focuses on HTTP/HTTPS services. The software has two parts. One is the device configuration file which is in JSON format, the other is the scanner, coded in perl, that does scanning, device identification and logging under the control the device configuration file.

Envoy - C++ front/service proxy

---

As on the ground microservice practitioners quickly realize, the majority of operational problems that arise when moving to a distributed architecture are ultimately grounded in two areas: networking and observability. It is simply an orders of magnitude larger problem to network and debug a set of intertwined distributed services versus a single monolithic application.

Mininet - An Instant Virtual Network on your Laptop (or other PC)

---

Mininet emulates a complete network of hosts, links, and switches on a single machine. It creates a realistic virtual network, running real kernel, switch and application code, on a single machine (VM, cloud or native), in seconds, with a single command.

Snort - Network Intrusion Prevention and Detection System

---

Snort is an open source network intrusion prevention and detection system (IDS/IPS) developed by Sourcefire. Snort can perform protocol analysis and content searching/matching. It can be used to detect a variety of attacks and probes, such as buffer overflows, stealth port scans, CGI attacks, SMB probes, OS fingerprinting attempts, and much more.

zarp - Network Attack Tool

---

Zarp is a network attack tool centered around the exploitation of local networks. This does not include system exploitation, but rather abusing networking protocols and stacks to take over, infiltrate, and knock out. Sessions can be managed to quickly poison and sniff multiple systems at once, dumping sensitive information automatically or to the attacker directly. Various sniffers are included to automatically parse usernames and passwords from various protocols, as well as view HTTP traffic and more. DoS attacks are included to knock out various systems and applications. These tools open up the possibility for very complex attack scenarios on live networks quickly, cleanly, and quietly. The long-term goal of zarp is to become the master command center of a network; to provide a modular, well-defined framework that provides a powerful overview and in-depth analysis of an entire network. This will come to light with the future inclusion of a web application front-end, which acts as the television screen, whereas the CLI interface will be the remote. This will provide network topology reports, host relationships, and more. zarp aims to be your window into the potential exploitability of a network and its hosts, not an exploitation platform itself; it is the manipulation of relationships and trust felt within local intranets. Look for zeb, the web-app frontend to zarp, sometime in the future.

exitmap - A fast and modular scanner for Tor exit relays.

---

Exitmap is a fast and modular Python-based scanner for Tor exit relays. Exitmap modules implement tasks that are run over (a subset of) all exit relays. If you have a background in functional programming, think of exitmap as a map() interface for Tor exit relays: Modules can perform any TCP-based networking task like fetching a web page, uploading a file, connecting to an SSH server, or joining an IRC channel.In practice, exitmap is useful to monitor the reliability and trustworthiness of exit relays. The Tor Project uses exitmap to check for false negatives on the Tor Project's check service and to find malicious exit relays. It is easy to develop new modules for exitmap; just have a look at the file HACKING in the doc/ directory or check out one of the existing modules.

pms-docker - Plex Media Server Docker repo, for all your PMS docker needs.

---

With our easy-to-install Plex Media Server software and your Plex apps, available on all your favorite phones, tablets, streaming devices, gaming consoles, and smart TVs, you can stream your video, music, and photo collections any time, anywhere, to any device. The bridge networking creates an entirely new network within the host and runs containers within there. This network is connected to the physical network via an internal router and docker configures this router to forward certain ports through to the containers within. The host networking uses the IP address of the host running docker such that a container's networking appears to be the host rather than separate. The macvlan networking creates a new virtual computer on the network which is the container. For purposes of setting up a plex container, the host and macvlan are very similar in configuration.

Weave - Simple, Resilient Multi-host Docker Networking

---

Weave is a simple, portable and reliable way to network and manage containers and microservices. It provides a simple and resilient network for your application that is portable across data centers and public clouds. Weave Net creates a virtual network that connects Docker containers across multiple hosts and enables their automatic discovery.

ApacheDS - Apache Directory Project

---

ApacheDS is an embeddable directory server entirely written in Java, which has been certified LDAPv3 compatible by the Open Group. Besides LDAP it supports Kerberos 5 and the Change Password Protocol. It has been designed to introduce triggers, stored procedures, queues and views to the world of LDAP which has lacked these rich constructs.

toxy - Hackable HTTP proxy for resiliency testing and simulated network conditions

---

Hackable HTTP proxy to simulate server failure scenarios, resiliency and unexpected network conditions, built for node.js.It was mainly designed for failure resistance testing, when toxy becomes particularly useful in order to cover fault tolerance and resiliency capabilities of a system, especially in disruption-tolerant networks and service-oriented architectures, where toxy may act as MitM proxy among services in order to inject failure.
