BACnet is a communication protocol for building automation and control (BAC) networks that use the ASHRAE, ANSI, and ISO 16484-5 standards [1] protocol.. BACnet was designed to allow communication of building automation and control systems for applications such as heating, ventilating, and air-conditioning control (), lighting control, access control, and fire detection systems and their ...
This is a list of POSIX (Portable Operating System Interface) commands as specified by IEEE Std 1003.1-2024, which is part of the Single UNIX Specification (SUS). These commands can be found on Unix operating systems and most Unix-like operating systems.
The r-commands were developed in 1982 by the Computer Systems Research Group at the University of California, Berkeley, based on an early implementation of TCP/IP (the protocol stack of the Internet). [2] The CSRG incorporated the r-commands into their Unix operating system, the Berkeley Software Distribution (BSD).
For most of the systems mentioned, protocol stacks are available in the form of CODESYS libraries which can be loaded subsequently onto the supported devices. In addition, the platform provides optional support for application-specific communication protocols, such as BACnet or KNX for building automation.
Distributed Network Protocol 3 (DNP3) is a set of communications protocols used between components in process automation systems. Its main use is in utilities such as electric and water companies. Its main use is in utilities such as electric and water companies.
The command Nmap is widely used in the video game Hacknet, allowing to probe the network ports of a target system to hack it. In Snowden , Nmap is used in the aptitude test scene about 14 minutes into the movie.
systemd is a system and service manager for Linux operating systems. systemctl is a command to introspect and control the state of the systemd system and service manager. Not to be confused with sysctl. systemd-analyze may be used to determine system boot-up performance statistics and retrieve other state and tracing information from the system ...
It originated with the 4.2BSD Unix operating system, which was released in 1983. A socket is an abstract representation ( handle ) for the local endpoint of a network communication path. The Berkeley sockets API represents it as a file descriptor in the Unix philosophy that provides a common interface for input and output to streams of data.
