"dh key too small" 与 Savon ruby gem

Question

升级到 Debian Buster 后，Savon 失败并显示：

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

我尝试通过更改 /etc/ssl/openssl.cnf

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

但没有效果，我无法控制远程站点，所以我无法更改 DH 密钥另见相关的 Debian 错误： 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

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

Answer 1

加油！ /etc/ssl/openssl.cnf 中的更改需要重新启动 ruby 进程，重新启动后错误消失！
