使用Java中的ssh2连接到由RSA SecurID保护的Linux系统

问题描述

我想创建一个从Windows系统到使用RSA令牌密码进行身份验证的Linux机器的连接，并且我想运行shell命令并从Java代码获取输出.使用腻子登录该Linux系统时，请执行以下步骤:

I want to create a connection from a Windows system to a Linux machine which uses RSA token Passcode for authentication and I want to run shell commands and get the output from the Java code. When logging into that Linux system using putty has the following steps:

1. 输入IP和端口并连接
2. 在PuTTY终端中输入用户名，询问登录为:"
3. 输入PASSCODE，然后输入RSA SecurID

我已经尝试使用Jsch包进行连接，但无法连接.我还尝试了一个jcabi-ssh( http://ssh.jcabi.com/)作为包装器Jsch.他们似乎都不适合我.

I have already tried connecting using Jsch package and it doesn't connect. I also tried a jcabi-ssh (http://ssh.jcabi.com/) which a wrapper for Jsch. None of them seem to work for me.

我使用Jsch软件包使用以下代码

I used the following code using the Jsch packages

        String host = "xxx";
        String user = "xxx";
        String password;

        Scanner scanner = new Scanner (System.in);
        System.out.println("Enter rsa token: ");
        password = scanner.nextLine();

        Session session = jsch.getSession(user, host, 2222);
        session.setPassword(password);
        session.connect();

我收到以下错误消息:

com.jcraft.jsch.JSchException: UnknownHostKey: myservername. RSA key fingerprint is ba:2b:70:2f:4f:fa:f6:20:31:56:e0:e8:8b:16:46:c9

我找到了一个解决方案，有人说包括这部分代码，它将StrictHostKeyChecking设置为"no":

I found a solution by someone saying include this piece of code which sets StrictHostKeyChecking to "no":

    java.util.Properties config = new java.util.Properties(); 
    config.put("StrictHostKeyChecking", "no");
    session.setConfig(config);

然后我的错误更改为:

com.jcraft.jsch.JSchException: Auth cancel

尝试使用其他jcabi-ssh实现也会得到类似的结果.

Trying with that other jcabi-ssh implementation gives similar results.

推荐答案

您正在寻找的是一个对话框，该对话框将在该时间点接受密码短语并建立连接.这是集成RSA SecureId所需要的- http://www.jcraft. com/jsch/examples/UserAuthPubKey.java.html

What you are looking for is a dialog which will accept the passphrase at that point in time and establish connection. Here is what you need to integrate RSA SecureId - http://www.jcraft.com/jsch/examples/UserAuthPubKey.java.html
