Ubuntu 16.04 openssl s_client write:errno=104

772

尝试通过 https 连接到 github.com、google.com、dropbox.com 时出现以下错误，但 stackoverflow.com、askubuntu.com 和大多数 https 网站都可以正常工作。

相关细节：

我在工作代理后面，但是在使用 Fedora 28 时我可以正常连接，只是在 Ubuntu 16.04 上我遇到了问题。办公室里没有其他人有这个问题，但他们大多使用 Mac。
这是在我自己的桌面上，而不是在服务器/VM/Docker 等上。
我可以通过我的移动热点或其他 WiFi 网络连接到这些网站
编辑：我在另一台装有 Ubuntu 16.04 的 Thinkpad 笔记本电脑上进行了测试，没有问题。所以这是这台机器特有的东西（戴尔 XPS 13 9370）。

错误信息：

我已将OpenSSL 升级到最新版本，但这没有什么区别：

$ openssl version
OpenSSL 1.0.2p  14 Aug 2018

运行 CURL 时出现以下错误：

$ curl -v https://google.com
* Rebuilt URL to: https://google.com/
*   Trying 172.217.17.46...
* Connected to google.com (172.217.17.46) port 443 (#0)

* ALPN, offering http/1.1
* gnutls_handshake() failed: Error in the pull function.
* Closing connection 0
curl: (35) gnutls_handshake() failed: Error in the pull function.

还有许多其他有类似问题的答案，但我找不到任何可以解决我的情况的答案：

这是与 stackoverflow.com 一起使用的示例：

编辑 2：感谢 Simon Sutter 的评论。我已经更新到 Ubuntu 18.04 试图解决它，但仍然存在类似的问题。

实际上 curl 错误现在略有不同，这很有用：

$ curl -v https://google.com

* Closing connection 0
curl: (35) OpenSSL SSL_connect: SSL_ERROR_SYSCALL in connection to google.com:443

搜索SSL_ERROR_SYSCALL错误时我遇到了一个SO 答案，该答案表明它可能与 IPv6 有关，并建议尝试wget. 这就是我得到的wget：

$ wget https://stackoverflow.com

有趣的是，谷歌发出了 IPv6 请求，但 stackoverflow 没有。然而，进一步的检查表明我对 bitbucket.org 也有问题，并且没有表明 IPv6 连接：

$ wget https://bitbucket.org/
--2018-09-26 10:03:40--  https://bitbucket.org/
Resolving bitbucket.org (bitbucket.org)... 18.205.93.2, 18.205.93.1, 18.205.93.0, ...
Connecting to bitbucket.org (bitbucket.org)|18.205.93.2|:443... connected.
Unable to establish SSL connection.

我通过禁用 IPv6对此进行了进一步检查，但这没有任何区别 - 因为我在运行curl或wget.

现在因为我在 Ubuntu 18.04 上，所以这里有一组更新的检查。

如果它是链中某处的证书错误，我知道我在第一次设置计算机时确实安装了工作 CA 证书。

我想我在 Ubuntu 问题上取得了一些进展。它适用于我尝试过的单独的 Ubuntu 16 笔记本电脑。此外，我认为我已将其归结为防火墙问题（通过此Security.SE 答案）以及 TLS v1.1 与 TLS v1.2 的处理。

我追踪了哪些网站我可以访问和哪些不能访问（上图）。一个有趣的例子是 bitbucket.org (fails) vs atlassian.net (works)。

然后，如果我尝试使用 openssl（强制 TLS v1.1）：

openssl s_client -connect bitbucket.org:443 -tls1_1 # this fails
openssl s_client -connect atlassian.net:443 -tls1_1 # this works

所以我认为防火墙可能会以某种方式阻止 TLS v1.2 流量。

当我运行时，在我的另一台 Ubuntu 机器上：

openssl s_client -connect bitbucket.org:443 -tls1_1 # this works!

在我尝试过的 Mac 上也是如此。

对此非常无聊的答案是我在防火墙后面。我排除了防火墙，因为它阻止了 google.com 和 outlook.office.com 之类的东西，而我是唯一遇到问题的人。

事实证明，因为我是公司的新人，所以我在新公司的笔记本电脑上进行了一些配置（我怀疑只是我的 MAC 被识别）（即使它是全新的 Ubuntu 安装），这意味着我的流量被防火墙拦截.
