本文提供了一个C#和Java实现SSH远程执行命令的示例代码，包括如何连接SSH服务器、发送命令并获取响应结果。C#部分使用了SharpSSH库，Java部分则使用了Ganymed SSH2库。

C#版：

添加sharpssh工程Tamir.SharpSSH.dll，sharpSshTest.exe，Org.Mentalis.Security.dll，DiffieHellman.dll

程序：

using System.Threading;
using System.Diagnostics;
using System.Net;
using System.Net.Sockets;
using System.Text;
using System;
using System.Collections;
using System.Collections.Generic;
using Tamir.SharpSsh;


namespace testSSH
{
    class Program
    {
        static void Main(string[]args)
        {
            String str=ssh_conn("ip","user","password","cmd");
            System.Console.Write(str);
            System.Console.Read();
        }
        public static string ssh_conn(string ip, string root, string pass, string command)
        {


            SshStream ssh = new SshStream(ip, root, pass);
            ssh.Prompt = "#";
            ssh.RemoveTerminalEmulationCharacters = true;
            //Writing to the SSH channel  
            string response = ssh.ReadResponse();
            ssh.Write(command);
            ssh.Flush();
            ssh.Write("/n");
            //Reading from the SSH channel  
            response = ssh.ReadResponse();
            return response;


        }    
    }
}

Java 版：

配置构建路径，添加ganymed-ssh2-build251beta1.jar

主类：

import ch.ethz.ssh2.Connection;
import ch.ethz.ssh2.Session;


public class test {
	public static void main(String argv[]){
		Connection conn=null;
		boolean isAuthenticated=false;
		try{
			conn=new Connection("ip");
			conn.connect();
			isAuthenticated=conn.authenticateWithPassword("user", "password");
			if(isAuthenticated==false){
				System.out.println("SSH Login faild");
			}
			else{
				Session sess=conn.openSession();
				System.out.println(new SysCpuInfo(sess).getCPUInfo());
				sess.close();
			}
		}catch(Exception e){
			System.out.println(e.toString());
		}
	}
}

功能类：

import java.io.BufferedReader;
import java.io.InputStream;
import java.io.InputStreamReader;
import java.util.StringTokenizer;


import ch.ethz.ssh2.Session;
import ch.ethz.ssh2.StreamGobbler;

	private int CPU_IDLE=0;
	int processStatus=0;

		StringTokenizer tokenStat=  null ;
		Session sess = null;
		String str = "";
		int i=0,j=0,cpuidle=0;
		try{
			sess=session;
			sess.execCommand("vmstat 2 10");//cmd
