TACACS and XTACACS both allow a remote access server to communicate with an authentication server in order to determine if the user has access to the network. TACACS Plus ( TACACS+ ) is a protocol developed by Cisco and released as an open standard beginning in 1993.
A terminal access controller (TAC) is a host computer that accepts terminal connections, usually from dial-up lines, and that allows the user to invoke Internet remote log-on procedures, such as Telnet.
A remote terminal unit (RTU) is a microprocessor-controlled electronic device that interfaces objects in the physical world to a distributed control system or SCADA (supervisory control and data acquisition) system by transmitting telemetry data to a master system, and by using messages from the master supervisory system to control connected objects.

A tap is typically a dedicated hardware device, which provides a way to access the data flowing across a computer network. The network tap has (at least) three ports: an A port, a B port, and a monitor port. A tap inserted between A and B passes all traffic (send and receive data streams) through unimpeded in real time, but also copies that ...
In computing, Mosh (mobile shell) is a tool used to connect from a client computer to a server over the Internet, to run a remote terminal. [2] Mosh is similar [3] to SSH, with additional features meant to improve usability for mobile users. The major features are:
Remote access may refer to: Connection to a data-processing system from a remote location, for example, through a remote access service or virtual private network; Remote desktop software, software allowing applications to run remotely on a server while displaying graphical output locally; Terminal emulation, when used to interface with a ...
A remote access service connects a client to a host computer, known as a remote access server. [1] The most common approach to this service is remote control of a computer by using another device which needs internet or any other network connection. Here are the connection steps: User dials into a PC at the office.
Remote login servers such as Secure Shell and Telnet servers play the same role but communicate with a remote user instead of a local one. Screen and Tmux are used to add a session context to a pseudoterminal, making for a much more robust and versatile solution. For example, each provides terminal persistence, allowing a user to disconnect ...
