我stunnel
在 Windows XP 上设置服务器,当客户端尝试访问时出现此错误:
2013.02.14 00:02:16 LOG7[8848:7664]: Service [https] accepted (FD=320) from 107.20.36.147:56160

知道该怎么办吗?我在网上读到这可能意味着我的服务器在宣传它可以在 SSL3 中通信,但实际上不能。如果这是真的,我想知道如何解决这个问题。我正在编辑该stunnel.conf
文件,但我不知道要在其中更改什么来解决此问题。
更新:
仅当 Twilio 客户端(即 Twilio 的服务器)尝试访问我的服务器时,才会显示以上错误消息。当我尝试使用我的一台计算机访问我的服务器时,该页面确实显示,但在内容显示后,Chrome 将页面显示为“正在加载”大约 30 秒,最后显示stunnel
以下消息:
transfer: s_poll_wait: TIMEOUTclose exceeded: closing
更新:
这是 wireshark 捕获:https ://gist.github.com/cool-RR/4963477

请注意,服务器在端口 8088 上运行。

这是来自服务器的日志(debug=7):

更新:
您应该进行网络捕获并查看它被拒绝的原因。还要检查两端的日志。增加
debug
stunnel conf 中的级别。您需要进行网络跟踪以确定客户端支持哪个版本的 SSL 协议。然后确保您的服务器也支持该版本。
资源
请注意,由于重新协商中的安全漏洞,SSL 协议在几年前已更改。请参阅CVE-2009-3555和有关 SSL 重新协商的页面
服务器响应:
您必须检查 SSL 服务器上的日志以了解它拒绝连接的原因。尝试在 stunnel 上启用 SSL 调试
debug=7
:stunnel
服务器有,但客户端正在options = NO_SSLv3
尝试使用 SSLv3 进行连接。您需要升级客户端以支持更新版本的 SSL,或者您需要更改stunnel
配置以接受 SSLv3。可能是客户端和服务器之间的 SSL 版本不匹配。通过在客户端上禁用较旧的 SSL 版本,确保客户端仅配置为 SSL3。
