Pi-hole makes use of a modified dnsmasq called FTLDNS, [13] cURL, lighttpd, PHP and the AdminLTE Dashboard [14] to block DNS requests for known tracking and advertising domains. The application acts as a DNS server for a private network (replacing any pre-existing DNS server provided by another device or the ISP ), with the ability to block ...
By the end of 2009, Volker Theile was the only active developer of FreeNAS, a NAS operating system that Olivier Cochard-Labbé started developing from m0n0wall in 2005. [6] [7] [8] m0n0wall is a variation of the FreeBSD operating system, and Theile decided he wanted to rewrite FreeNAS for Linux.
Docker is a set of platform as a service (PaaS) products that use OS-level virtualization to deliver software in packages called containers. [5] The service has both free and premium tiers.

OPNsense has a web-based interface and can be used on the x86-64 platform. [5] Along with acting as a firewall, it has traffic shaping, load balancing, captive portal and virtual private network capabilities, and others can be added via plugins.
A null route or black hole route is a network route (routing table entry) that goes nowhere. Matching packets are dropped (ignored) rather than forwarded, acting as a kind of very limited firewall . The act of using null routes is often called blackhole filtering .
In quantum gravity, a virtual black hole [1] is a hypothetical micro black hole that exists temporarily as a result of a quantum fluctuation of spacetime. [2] It is an example of quantum foam and is the gravitational analog of the virtual electron – positron pairs found in quantum electrodynamics .
OpenVPN is a virtual private network (VPN) system that implements techniques to create secure point-to-point or site-to-site connections in routed or bridged configurations and remote access facilities.
Meltdown exploits a race condition, inherent in the design of many modern CPUs.This occurs between memory access and privilege checking during instruction processing. . Additionally, combined with a cache side-channel attack, this vulnerability allows a process to bypass the normal privilege checks that isolate the exploit process from accessing data belonging to the operating system and other ...
