What is telnet-client?

The telnet-client npm package is a simple and easy-to-use library for creating and managing Telnet connections in Node.js. It allows you to connect to Telnet servers, send commands, and receive responses, making it useful for automating tasks, remote server management, and network device configuration.

What are telnet-client's main functionalities?

Establishing a Telnet Connection

This feature allows you to establish a connection to a Telnet server using specified parameters such as host, port, shell prompt, and timeout.

const Telnet = require('telnet-client');
let connection = new Telnet();

let params = {
  host: '127.0.0.1',
  port: 23,
  shellPrompt: '/ # ',
  timeout: 1500
};

connection.connect(params)
  .then(() => {
    console.log('Connected to the Telnet server');
  })
  .catch((error) => {
    console.error('Connection failed:', error);
  });

Sending Commands

Once connected, you can send commands to the Telnet server and handle the responses. This is useful for executing remote commands and automating tasks.

connection.send('ls -l')
  .then((response) => {
    console.log('Command response:', response);
  })
  .catch((error) => {
    console.error('Command failed:', error);
  });

Handling Connection Events

You can handle various connection events such as timeout and close to manage the connection lifecycle and handle errors or disconnections gracefully.

connection.on('timeout', () => {
  console.log('Connection timed out');
  connection.end();
});

connection.on('close', () => {
  console.log('Connection closed');
});
