我正在构建一个Web服务器(
http://blog.linformatronics.nl/),它在IPv4和IPv6以及使用非SSL连接时都能正常运行.但是,当我通过https连接到它时,IPv6按预期工作,但IPv4连接会引发客户端错误. IPv4 / https连接的服务器端日志为空.在表格中总结：
| http | https -----+-------+------------------------------------------------------- IPv4 | works | OpenSSL error,Failed. No server side logging. -----+-------+------------------------------------------------------- IPv6 | works | self signed certificate warning,but works as expected
显然,甚至没有设置SSL隧道,这说明Apache日志是空的.但为什么它适用于IPv6并且IPv4失败？
我的问题是为什么抛出这个OpenSSL错误,我该如何解决？
以下是有关设置的一些额外信息.
IPv6 https
用于重现IPv6 / https行为的命令：
$wget --no-check-certificate -O /dev/null -6 https://blog.linformatronics.nl

解决方法
您有一些严重的防火墙/ NAT配置错误.您实际上并未在端口443上运行Web服务器…
$telnet 82.95.251.247 443 Trying 82.95.251.247... Connected to 82.95.251.247. Escape character is '^]'. SSH-2.0-OpenSSH_6.0p1 Debian-3ubuntu1
您的IPv6服务似乎已被防火墙关闭……
$telnet 2001:980:1b7f:1:a00:27ff:fea6:a2e7 443 Trying 2001:980:1b7f:1:a00:27ff:fea6:a2e7... telnet: connect to address 2001:980:1b7f:1:a00:27ff:fea6:a2e7: Permission denied
修复您的防火墙和/或错误端口服务问题,您应该发现事情开始起作用.
