    Linux Test Project

    Testsuite to validate the reliability, robustness, stability of Linux.

    Linux Test Project (LTP) is a joint project started by SGI, OSDL and Bull developed and maintained by SUSE, Red Hat, Fujitsu, IBM, Cisco, Oracle and others. The project goal is to deliver tests to the open source community that validate reliability, robustness, and stability of the Linux Kernel. The testing suites contain a collection of tools for testing the Linux kernel and related features. Our goal is to improve the Linux kernel and system libraries by bringing test automation.

    ESP8266 Deauther Version 2

    ESP8266 Deauther Version 2

    Affordable WiFi hacking platform for testing and learning

    Scan for WiFi devices, block selected connections, create dozens of networks and confuse WiFi scanners! Version 3 is in development. It is stable to use, but it is very different. It is command-line based, which allows it to offer not just more features, but make them more customizable. This software allows you to easily perform a variety of actions to test 802.11 wireless networks by using an inexpensive ESP8266 WiFi SoC (System On A Chip). The main feature, the deauthentication attack, is used to disconnect devices from their WiFi network. No one seems to care about this huge vulnerability in the official 802.11 WiFi standard, so I took action and enabled everyone who has less than 10 USD to spare to recreate this project. I hope it raises more attention on the issue. In 2009 the WiFi Alliance actually fixed the problem (see 802.11w), but only a few companies implemented it into their devices and software.

    stress-ng

    stress-ng

    This is the stress-ng upstream project git repository.

    This is the stress-ng upstream project git repository. stress-ng will stress test a computer system in various selectable ways. It was designed to exercise various physical subsystems of a computer as well as the various operating system kernel interfaces. stress-ng was originally intended to make a machine work hard and trip hardware issues such as thermal overruns as well as operating system bugs that only occur when a system is being thrashed hard. Use stress-ng with caution as some of the tests can make a system run hot on poorly designed hardware and also can cause excessive system thrashing which may be difficult to stop.
