Telnet is a protocol used on the internet to provide bidirectional communication. This way the server and the client can communicate with each other. The difference between a bidirectional and unidirectional communication is, let is the example of a telephone; this is a bidirectional communication channel. In this type of communication both the users are able to talk to each other. In a unidirectional communication channel, only one of the users would be able to communicate. The perfect example for this would be a TV and its station. Here the TV station sends a signal which is displayed on the screen, but the TV would not be able to communicate back to the station. In telnet, the user data is interspersed in band with telnet control information in an 8-bit byte-oriented TCP connection.
Internet Applications

Telnet, a standard TCP/IP protocol for virtual terminal service, proposed by ISO, enables the establishment of a connection to a remote system in such a way that the local terminal appears to be a terminal at the remote system. Telnet is an abbreviation for TErminaLNETwork. The Telnet protocol offers a user the possibility to connect and log on to any other host in the network from the user’s own computer by offering a remote log-in capability. For the connections, Telnet uses the TCP protocol. The Telnet service is offered on the host machine at TCP port 23. The user at the terminal interacts with the local Telnet client. The Telnet client acts as a terminal accepting any keystrokes from the keyboard, interpreting them and displaying the output on the screen. The client on the computer makes the TCP connection to the host machine’s port 23 where the Telnet server answers. The Telnet server interacts with applications in the host machine and assists in the terminal emulation (Figure 2.8).
The Internet

TELNET is a powerful Internet command that allows remote logon to another computer (“remote-host”) on the Internet. TELNET is similar to dialing into another computer, except that you are spared the expense and hassle of a modem, communication software, and a long-distance phone call. You must have a valid login id and (usually) a password to use a remote computer. Some computers feature “generic” userids (e.g., GOPHER, LIBCAT, INFORMU) that allow you to logon (often without supplying a password) and access general information files via a series of menus. Typically, you would initiate a TELNET connections as follows. Note that in many UNIX-based systems, commands may be case-sensitive. TELNET <remote-host domain name>

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).
Vision improvement system using image processing technique for adverse weather condition of opencast mines

The Assisted Driving System (ADS) is aimed to improve safety under low visibility conditions by providing better and more information to operators of heavy earth moving machinery [7]. The developed VIS system comprises single channel unit with additional features to add multiple channels as per requirement. There are five control channels namely: Serial port, USB, Telnet, HTTP and web browser control/ client-side control as shown in Table 1. The first three connections are normally used for integration into an external control console using peripherals [8]. Commands over HTTP, is most suitable when controlling the developed system from web-based control console. The developed system can also be controlled by any end device using browser or desktop application.
Countermeasures against large-scale reflection DDoS attacks using exploit IoT devices

Most of these IoT malwares are from the United States, Italy, the United Kingdom, and Germany. Since the use of wired/wireless routers, IP cameras, smart home appliances, and other IoT systems and devices is so widespread in these countries, they are almost never safe from malware [7]. The threat of malware is compounded by the fact that many IoT device manufacturers still don't take security vulnerabilities into serious consideration when releasing their products in the market. It has even been found that some devices are extremely susceptible to outside attacks via their Telnet port, and attackers can simply download and run malware on such devices [8]. At the very least, most IoT devices are vulnerable to potential DDoS attacks at anytime [9].
