Java连接并登陆SSH（需要用到的jar包-ganymed-ssh2-build210.jar）：

package org.javaweb.util;
import java.io.IOException;
import ch.ethz.ssh2.Connection;
public class Ssh {
	public boolean login(String host,int port,String user,String password){
		boolean l = false;
		try {
			Connection conn = new Connection(host, port);
			conn.connect();
			l = conn.authenticateWithPassword(user, password);
			conn.close();
		} catch (IOException e) {
			System.out.println(e.toString());
		}
		return l;
	}
}
