【中文标题】net.schmizz.sshj.userauth.UserAuthException:用尽可用的身份验证方法【英文标题】:net.schmizz.sshj.userauth.UserAuthException: Exhausted available authentication methods 【发布时间】:2013-03-26 04:12:22 【问题描述】:第一次询问***,也使用sshj。除了 sshj 提供的示例之外,我还没有找到任何好的资源来帮助使用这个 API。
我一直在尝试使用 sshj 进行远程端口转发,但遇到了这个错误。
Exception in thread "main" net.schmizz.sshj.userauth.UserAuthException: Exhausted available authentication methods
我使用虚拟机测试了身份验证,但没有使用公钥。我将使用它连接到我知道登录名的 EC2 实例。
public void startRemotePortForwardingConnection(LocalPortForwarder.Parameters parameters) throws IOException
sshClient.connect(parameters.getLocalHost());
this.connectionStatus = CONNECTED;
System.out.print("Connected to localhost" + NEWLINE);
try
sshClient.authPassword(this.username, this.password);
System.out.print("Authorized with as user " + username + " with password " + password + NEWLINE);
// the local port we should be listening on
RemotePortForwarder.Forward localPortToListenOn = new RemotePortForwarder.Forward(parameters.getLocalPort());
System.out.print("localPortToListenOn initialized" + NEWLINE);
// where we should forward the packets
InetSocketAddress socketAddress = new InetSocketAddress(parameters.getRemoteHost(), parameters.getRemotePort());
SocketForwardingConnectListener remotePortToForwardTo = new SocketForwardingConnectListener(socketAddress);
System.out.print("remotePortToForwardTo initialized" + NEWLINE);
//bind the forwarder to the correct ports
sshClient.getRemotePortForwarder().bind(localPortToListenOn, remotePortToForwardTo);
System.out.print("ports bound together" + NEWLINE);
sshClient.getTransport().setHeartbeatInterval(30);
sshClient.getTransport().join();
finally
sshClient.disconnect();
可能不是最好的(甚至是正确的)方法。
【问题讨论】:
SSHJ - Keypair login to EC2 instance的可能重复 【参考方案1】:尝试使用 client.addHostKeyVerifier(new PromiscuousVerifier());
。我发送了两个配置,第一个是公钥,第二个是用户名/密码。
private static SSHClient setupSshj(String remoteHost, String username, String password) throws Exception
SSHClient client = new SSHClient();
client.addHostKeyVerifier(new PromiscuousVerifier());
client.connect(remoteHost);
client.authPassword(username, password);
return client;
private static SSHClient setupSshWithPublicKey(String remoteHost, int port, String username, String publicKey) throws Exception
SSHClient client = new SSHClient();
client.addHostKeyVerifier(new PromiscuousVerifier());
client.connect(remoteHost, port);
client.authPublickey(username, publicKey);
return client;
【讨论】:
【参考方案2】:我为之前的一个类似问题写了一个示例,您可以直接在 groovyconsole 中运行该示例,该示例将连接到 EC2 实例:https://***.com/a/15800383/311525
