How to Connect to an SSH Server Using Java's JSCH Library?

Connecting to SSH Using Java

SSH, or Secure Shell, is a powerful tool for securely connecting to remote servers. In Java, there are multiple SSH libraries available to help you establish and manage SSH connections.

One of the most well-renowned Java SSH libraries is the Java Secure Channel (JSCH) library. Its popularity stems from its use in various Java-based tools and applications, including Maven, Ant, and Eclipse. It is an open-source library distributed under a BSD style license.

Example:

To connect to an SSH server using JSCH:

import com.jcraft.jsch.JSch;
import com.jcraft.jsch.Session;

public class SSHConnection {

    public static void main(String[] args) throws Exception {
        // SSH server hostname
        String hostname = "example.com";
        // SSH server port
        int port = 22;
        // SSH username
        String username = "username";
        // SSH password
        String password = "password";

        JSch jsch = new JSch();

        // Create a new SSH session
        Session session = jsch.getSession(username, hostname, port);
        session.setPassword(password);

        // Connect to the SSH server
        session.connect();

        // SSH command execution (optional)
        // Execute a remote command on the server
        String command = "ls -l";
        String result = session.execCommand(command).getStdOut();
        System.out.println(result);

        // Disconnect from the SSH server
        session.disconnect();
    }
}

This code snippet demonstrates how to establish an SSH connection, execute a remote command, and retrieve its output using the JSCH library in Java.
