我的客户端代码使用apache.sshd.SshClient来ssh到服务器。如果服务器的默认密码提示为＆＃34;密码：＆＃34;，则连接成功。如果服务器有任何其他密码提示，请说 - ＆＃34;自定义密码提示：＆＃34;，waitFor会立即返回ClientSession.CLOSED。两种情况下的实际用户名和密码都相同，只有服务器端密码提示不同。对服务器的手动ssh适用于所有提示。
由于安全性要求，我无法在服务器上更改密码提示。我只能控制在OSGI上运行的客户端代码。在apache sshd中是否有任何选项，或者是否有任何其他尝试/推荐的ssh库可以处理来自服务器的任何密码提示？
感谢。
这是代码的外观 -
import org.apache.sshd.ClientSession;
import org.apache.sshd.SshClient;
import org.apache.sshd.client.future.ConnectFuture;
class MySshClient {
ClientSession clientSession;
SshClient sshClient = SshClient.setUpDefaultClient();
sshClient.start();
try {
ConnectFuture connectFuture = sshClient.connect(username, ipAddress, 22);
boolean isConnected = false;
try {
isConnected = connectFuture.await(timeout);
} catch (InterruptedException e) {
throw new CustomException("InterruptedException for connect await");
}
if (!isConnected) {
throw new CustomException("isConnected false");
}
clientSession = connectFuture.getSession();
clientSession.addPasswordIdentity(password);
try {
clientSession.auth().await(timeout);
} catch (InterruptedException e) {
throw new CustomException("InterruptedException for auth await");
}
int ret = clientSession.waitFor(ClientSession.CLOSED | ClientSession.AUTHED, timeout);
if ((ret & ClientSession.CLOSED) != 0) {
LOG.error("auth waitFor returned {}",ret);
throw new CustomException("Session CLOSED !!");
}
}
}
