java错误：140770FC:SSL例程：SSL23_GET_SERVER_HELLO:未知协议

Question

我目前正在尝试测试在Cloudera Hadoop环境中为实现加密洗牌的安全性而实施的更改

我已经创建了证书和密钥库，并将它们保存在适当的位置

我正在测试TaskTracker的HTTPS端口50060

当我在那个端口上做卷曲时，我得到的是错误响应

ubuntu@node2:~$ curl -v -k "https://10.0.10.90:50060"
* About to connect() to 10.0.10.90 port 50060 (#0)
*   Trying 10.0.10.90... connected
* successfully set certificate verify locations:
*   CAfile: none
  CApath: /etc/ssl/certs
* SSLv3, TLS handshake, Client hello (1):
* error:140770FC:SSL routines:SSL23_GET_SERVER_HELLO:unknown protocol
* Closing connection #0
curl: (35) error:140770FC:SSL routines:SSL23_GET_SERVER_HELLO:unknown protocol

当我向OpenSSL客户端进行检查时，我得到了以下响应

 ubuntu@node2:~$ openssl s_client -connect 10.0.10.90:50060
CONNECTED(00000003)
139749924464288:error:140770FC:SSL routines:SSL23_GET_SERVER_HELLO:unknown protocol:s23_clnt.c:749:

我不知道是什么导致了这个问题

有什么我遗漏的吗

PS：我已经更新了ca-certificates.crt文件，还将服务器.crt文件保存在/usr/share/ca-certificates/mozilla

error:140770FC:SSL routines:SSL23_GET_SERVER_HELLO:unknown protocol

10.0.10.90:50060上似乎没有SSL/TLS服务器在侦听。有一个服务器正在监听，但它不是SSL/TLS

当通过端口80（而不是443）连接到网关时，我可以复制它

$ openssl s_client -connect 192.168.1.1:80
CONNECTED(00000003)
140735109476828:error:140770FC:SSL routines:SSL23_GET_SERVER_HELLO:unknown protocol:s23_clnt.c:787:

如果使用-debug标志，您将在OpenSSL试图解释为SSL/TLS协议数据的响应中看到HTTP：

$ openssl s_client -connect 192.168.1.1:80 -debug

Answer 2

对于任何有此问题的人：

error:140770FC:SSL routines:SSL23_GET_SERVER_HELLO:unknown protocol.

我的问题是curl默认使用ipv6而不是ipv4。终端服务器未正确配置以响应ipv6，因此观察到了相同的问题陈述。确保curl正在使用ipv4，或者您的服务器可以使用ipv6
