如何在android中以编程方式运行SSH命令

我想运行一个简单的SSH命令，比如

SSH-r80:localhost:1337 serveo.net

，我知道有库可以做到这一点，但是没有用户名和密码它就无法工作。在我的情况下，不需要身份验证。我该怎么做

更新 当我运行命令ssh-r80:localhost:1337 serveo.net-v时，我得到以下输出

debug1: Server host key: ssh-rsa SHA256:07jcXlJ4SkBnyTmaVnmTpXuBiRx2+Q2adxbttO9gt0M

文件。

我不认为您的ssh命令没有使用任何身份验证。请使用verbose out和

ssh-v…

验证它。我猜它使用

publickey

和

~/.ssh/id\u rsa

中的默认密钥

id\u rsa

，服务器只接受任何密钥

如果是这种情况，您可以使用jsch执行同样的操作

final JSch jSch = new JSch();
jSch.addIdentity(idRsaFile);
final Session newSession = jSch.getSession(null, "serveo.net", 22);
newSession.setConfig("PreferredAuthentications", "publickey");
newSession.setConfig("StrictHostKeyChecking", "no");

session.setUserInfo(new UserInfo() {
        @Override
        public String getPassphrase() {
            return null;
        }

        @Override
        public String getPassword() {
            return null;
        }

        @Override
        public boolean promptPassword(String message) {
            return false;
        }

        @Override
        public boolean promptPassphrase(String message) {
            return false;
        }

        @Override
        public boolean promptYesNo(String message) {
            return false;
        }

        @Override
        public void showMessage(String message) {

        }
    });
newSession.connect(connectTimeout);

然后

newSession.setPortForwardingR(...);

下面是一个通过Jsch使用serveo的示例。这里唯一真正的“把戏”似乎是针对serveo的。在会话打开“shell”或“exec”通道之前，Serveo不会接受隧道请求。Serveo使用shell/exec通道向客户端发送状态消息。因此，有必要先打开shell或exec通道，然后请求远程转发

SSH协议要求客户端提供一个用户名作为登录名。

ssh

命令行实用程序默认使用本地用户名（如果您不提供）。类似地，Jsch默认使用的值为。Serveo有些不同寻常，因为它可以接受来自任何人的SSH连接，所以您可以使用任何您喜欢的名称。您可以让jsch使用其默认名称——假设它在android上工作——或者您可以使用硬编码名称，如“x”或“foo”

试试这个我想用编程的方式来做我不建议这样做，但我建议您使用“-v”标志运行ssh命令来打印调试信息，然后您的问题包括成功调用的调试信息。你问题的全部前提可能是错误的。Ssh可能在您不知道的情况下提供用户名和身份验证。谢谢您的回答。但在安卓系统中，该文件位于何处？顺便说一句，我还检查了我的电脑，在

.ssh

文件夹中有一个名为

已知\u hosts

的文件。运行该命令后，该文件的值如下所示``````1´JPsTEjrqseCiLxjSr+00Ad6xGMc=| KKxBd62AgPo0sfeezhh8aGsja20=ssh rsa。。。。。。。。。但在我的终端中，我得到了类似于

debug1:Server host key:ssh rsa SHA256:07jcXlJ4SkBnyTmaVnmTpXuBiRx2+q2adxbtoto9gt0m的东西

我试图在

jSch.addIdentity（）

方法中传递该字符串，但我得到了文件未找到异常。非常感谢，您能告诉我，您使用的是哪个版本的jSch吗？我仍然得到“用户名”并没有例外。我正在尝试从android上运行这个。嘿，非常感谢，我能够找到答案。现在它正在做我想要的事情。你帮了我很多。你好sirServeo不在乎你使用什么用户名。如果您发现必须提供用户名，可以使用硬编码值，如“x”或“foo”。
