Ubuntu cUrl/OpenSSL握手失败与fritzbox

Question

我尝试在VPS上使用一个简单的php脚本将一些数据插入到我的fritz.box (6360电缆)中。

Anotherserver.net是来自我的fritzbox的有效的非ip入口(并且fritzbox可以从公共访问)。

php脚本试图压缩服务器以获得ssl会话，但是它以握手错误告终。因此，我尝试了简单的curl命令，如下所示。curl命令以相同的错误结尾。令人困惑的是，-k/-不安全的开关不会改变任何东西。第二，openssl命令(如您可以看到的更多)可以完全正常工作。

root@server:/var/www/mycurl# curl -v -L  --sslv3  --cacert cert_file.pem https://anotherserver.net

我的服务器openssl版本是：

root@server:/var/www/mycurl# openssl version
OpenSSL 1.0.1f 6 Jan 2014

我的服务器卷版本是：

root@server:/var/www/mycurl# curl --version
curl 7.35.0 (x86_64-pc-linux-gnu) libcurl/7.35.0 OpenSSL/1.0.1f zlib/1.2.8 libidn/1.28 librtmp/2.3

Features: AsynchDNS GSS-Negotiate IDN IPv6 Largefile NTLM NTLM_WB SSL libz TLS-SRP

我的OpenSSL版本的fritz.box似乎是0.98。

编辑19.08.2014: cert_file.pem实际上是bjaux.ddns.net.pem --“另一个服务器”(也就是bjaux.ddns.net)的证书文件，我用google从给定站点下载了该文件。我还试着把它重命名为bjaux-ddns-net.pem，但是curl不起作用。请注意，openssl s_client总是返回验证返回代码0- Openssl s_client工作。完全是。从那以后就起作用了。只有curl命令才是握手的问题。

Answer 1

fritz!box上的服务器似乎只支持两个密码: RC4-SHA和RC4-MD5。虽然openssl s_client提供这些密码，但curl不提供。看起来他们已经显式地删除了任何RC4密码，请参见http://curl.haxx.se/mail/tracker-2014-03/0014.html。

如果显式地将--ciphers 'RC4-SHA'添加到选项中，则连接将成功。

Answer 2

请拿上这张自签证书：

将其保存在一个名为bjaux-ddns-net.pem的文件中。然后试着：

openssl s_client -connect anotherserver.net:443 -CAfile bjaux-ddns-net.pem

您将以一个Verify Result: 0 (ok)结束

$ openssl s_client -connect ...
