带有Savon ruby gem的"dh key太小“

Question

升级到Debian Buster后，Savon失败，并显示以下错误：

SSL_connect returned=1 errno=0 state=error: dh key too small

我尝试更改/etc/ssl/openssl.cnf

[system_default_sect]
#MinProtocol = TLSv1.2
#CipherString = DEFAULT@SECLEVEL=2
MinProtocol = None
CipherString = DEFAULT

但是没有效果，我无法控制远程站点，所以我不能更改DH密钥参见相关的Debian bug：https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=907788

系统信息：

ruby version: ruby 2.5.5p157 (2019-03-15 revision 67260) [x86_64-linux-gnu]
savon version: 2.12.0

我还在这里输入了一个问题https://github.com/savonrb/savon/issues/914

ups！在重启错误消失后，重新启动ruby进程所需的/etc/ssl/openssl.cnf中的更改！
