在使用Heartbleed修复升级到最新的OpenSSL之后,我在使用内核3.2.0-54的两个Ubuntu 12.04实例上遇到了这个问题.通过HTTPS连接到某些服务器之前从未超时的现在正在这样做.特别是,我在连接Rackspace Cloud Files和
Rubygems时遇到问题.
OpenSSL版本是OpenSSL 1.0.1 2012年3月14日,建立于：2014年4月7日星期一20:33:29 UTC.我认为我有最新的ca-certificates包并且运行update-ca-certificates既不添加也不删除任何证书.
以下是对rubygems.org的curl尝试的详细输出.从同一网络上尚未升级到最新OpenSSL的服务器和我的OS X笔记本电脑运行时,此查询成功返回：
>> curl https://rubygems.org/api/v1/versions/rubygems-update.json --verbose --trace-time 16:16:18.985045 * About to connect() to rubygems.org port 443 (#0) 16:16:18.985181 * Trying 54.245.255.174... connected 16:16:19.049839 * successfully set certificate verify locations: 16:16:19.049881 * CAfile: none CApath: /etc/ssl/certs 16:16:19.050177 * SSLv3,TLS handshake,Client hello (1): 16:17:28.642516 * UnkNown SSL protocol error in connection to rubygems.org:443 16:17:28.642584 * Closing connection #0 curl: (35) UnkNown SSL protocol error in connection to rubygems.org:443
此外,这里是使用openssl测试连接的输出(两个已升级的服务器都是相同的)：

这可能与Ubuntu OpenSSL包有关吗？我不确定在这一点上要尝试什么,或者如何诊断可能发生的事情.
提前致谢.

为了在OpenSSL升级后ssh到其中一个服务器,我不得不更改我的本地OSX ssh_config文件,如下所示：https://superuser.com/a/597956.不确定这是否相关,但似乎可能是这样.
数据包捕获
以下是失败请求的数据包捕获序列：

当我将此与成功的请求进行比较时,有一点突出的是失败的请求使用SSL而成功的请求使用了TLSv1.1.
这是另一个失败请求的另一个数据包捕获序列.这个由于超时而失败但是可重复并且不会导致其他机器超时.

根据下面的讨论,两个场景中的Continuation Data数据包在wireshark中查看时,即使有可见字节,也不会在SSL部分显示任何内容.对于第一次数据包捕获,字节数小于第二次捕获的字节数.事实上,在第二次捕获中,有可见的文本使我相信它是证书的一部分.
