### windows ###

使用共享目录形式访问【smb协议】

<dependency>
        <groupId>ch.ethz.ganymed</groupId>
        <artifactId>ganymed-ssh2</artifactId>
        <version>262</version>
    </dependency>

public static void main(String[] args) throws Exception {
            NtlmPasswordAuthentication auth = new NtlmPasswordAuthentication("smb://192.111.111.11","username", "password");
    
            SmbFile file = new SmbFile("smb://192.111.111.11/xx/xx/skywalking/agent.zip", auth);
    
            if (!file.exists()){
                System.out.println("exists is true");
            }
    
            //byte
            file.length();
        }

### Linux ###

使用ssh协议登录后执行shell命令【ssh2】

<dependency>
        <groupId>jcifs</groupId>
        <artifactId>jcifs</artifactId>
        <version>1.3.17</version>
    </dependency>

public static void main(String[] args) throws Exception{
            String hostname = "10.111.111.111";//远程机器IP
            String username = "root";//登录用户名
            String password = "111111";//登录密码
    
            try {
                Connection conn = new Connection(hostname);
    
                conn.connect();
    
                boolean isAuthenticated = conn.authenticateWithPassword(username, password);
                ///是否登录成功
                if (isAuthenticated == false) {
                    throw new IOException("认真失败！！！");
                }
                Session sess = conn.openSession();
                //执行命令
                sess.execCommand("uname -a && date && uptime && who");
                //获取文件大小
                //ls -ll /opt/deploy/ | grep xxxx-1.1.jar | awk '{print $5}'
    
                System.out.println("Here is some information about the remote host:");
    
                //创建输入流
                InputStream stdout = new StreamGobbler(sess.getStdout());
                //字符流
                BufferedReader br = new BufferedReader(new InputStreamReader(stdout));
    
                while (true) {
                    String line = br.readLine();
                    if (line == null)
                        break;
                    System.out.println(line);
                }
                System.out.println("ExitCode: " + sess.getExitStatus());
                //关闭连接
                sess.close();
                conn.close();
            } catch (IOException e) {
                e.printStackTrace(System.err);
                System.exit(2);
            }
        }
