High-Performance Switch/Routers
Published in James Aweya, Designing Switch/Routers, 2023
Secure Shell (SSH) is a network protocol that supports a number of cryptographic features and is used for accessing network services securely over a network that is not secured. Some of the typical and everyday applications of SSH include remote machine login, remote command-line, and remote command execution. SSH can also be used to secure a wide range of network services.

Upon completion of these basic four steps in the graphical interface shown in Fig. 3, a TRANSP run is then successfully prepared and can be packaged and submitted to the TRANSP grid for running on the computing cluster at the Princeton Plasma Physics Laboratory (PPPL). OMFIT has inherent knowledge about the server in which the Python application is running and the available servers for direct secure shell login. The user may be interacting with OMFIT on their personal laptop or institutional workstation, but executing scripts on remote servers. For local analyses running OMFIT at PPPL, the job is directly submitted to the local servers, but for remote submission from DIII-D and JET, the data transfer and authentication are provided by the Open Science Grid. The logic for this decision making is handled internally to the OMFIT scripting without requiring user interaction.

To perform wireless transmission, the connection configuration for the RN-XV Wi-Fi module must be completed before receiving the ECG and GPS signals from the microprocessor control unit (MCU). There are many network connection tools available for this purpose. In this study, we adopted Tera Term for Wi-Fi transmission, a free terminal connection, that supports Telnet and secure shell (SSH), and it can also execute command-line instructions through batch processing. The following is the process of Wi-Fi transmission via Tera Term. First, the RN-XV Wi-Fi module was connected to an Xbee USB adapter board, then, the Tera Term terminal connection tool was activated, and the serial port was selected to enter the program editing interface (Figure 9).

DHT-11 temperature and humidity sensors have been interfaced with Raspberry pi zero/w, an ARM processor-based stand alone microcontroller board, having ARM processor of 1 GHz single core CPU, RAM – 512 MB and 802.11 b/g/n wireless LAN, to construct the measuring nodes and are placed at each wall of the experimental space. All these decentralized thermal zones have been investigated with separately installed measuring nodes, and integrated with TCP/IP based wireless local area network (LAN) through secure shell (SSH) network communication protocol to a centralized computer-based data acquisition and computing station. The specification of the cental computer is as follows: processor – Intel i3 seventh generation, 3.90 GHz, RAM – 8 GB, HDD – 500 GB.
