这是我的代码,它在远程服务器上检索文件的内容并显示为输出.

package sshexample;

import com.jcraft.jsch.*;
import java.io.*;

public class SSHexample 
{
public static void main(String[] args) 
{
    String user = "user";
    String password = "password";
    String host = "192.168.100.103";
    int port=22;

    String remoteFile="sample.txt";

    try
    {
        JSch jsch = new JSch();
        Session session = jsch.getSession(user, host, port);
        session.setPassword(password);
        session.setConfig("StrictHostKeyChecking", "no");
        System.out.println("Establishing Connection...");
        session.connect();
        System.out.println("Connection established.");
        System.out.println("Creating SFTP Channel.");
        ChannelSftp sftpChannel = (ChannelSftp) session.openChannel("sftp");
        sftpChannel.connect();
        System.out.println("SFTP Channel created.");
        InputStream out= null;
        out= sftpChannel.get(remoteFile);
        BufferedReader br = new BufferedReader(new InputStreamReader(out));
        String line;
        while …

我有一个看起来像SSHJ测试中的pem文件(虽然我没有看到它被引用):https://github.com/shikhar/sshj/blob/master/src/test/resources/hostkey.pem.只是尝试通过pem文件验证到EC2实例(读作字符串),但有麻烦.有人做过吗？

    SSHClient ssh = new SSHClient();
    ssh.connect("ec2-XXXXXXX.compute-1.amazonaws.com");
    ssh.authPublickey("ubuntu", getPemAsString("/Users/me/ec2.pem"));
    final Session session = ssh.startSession();
    session.exec("echo -e \"test\" >> /home/ubuntu/testfile");

错误如下:
