那些遇到过的问题

由于 SSL 问题，Azure DevOps 部署代理无法连接

Stu*_*urf 6 azure-devops azure-agent

由于 SSL 问题，Azure 部署代理几天后不再工作。

我有几台服务器无法再连接到 Azure DevOps。

我发现以下博客应该启用tls 1.2。

https://devblogs.microsoft.com/visualstudio/azure-devops-requires-tls-1-2-on-all-connections-include-visual-studio/

我检查了我们是否启用了正确的安全协议。

C:\azagent\A2> [System.Net.ServicePointManager]::SecurityProtocol
Ssl3, Tls, Tls12

我还按照以下步骤确保在 Windows 寄存器中启用了 TLS。我手动添加了这些值，因为有些值不存在。

如果人们仍然遇到这种情况，我找到了一个脚本来检查所有问题并生成一个有效的解决方案:-)

Azure DevOps TLS 1.2 过渡准备情况检查器

Azure DevOps 服务（与许多其他 Microsoft 服务一样）正在过渡，以弃用传输协议 TLS 1.0、TLS 1.1 和一些被认为较弱的 TLS 1.2 密码套件。

请参阅 Azure DevOps 团队的公告：https://devblogs.microsoft.com/devops/deprecating-weak-cryptographic-standards-tls-1-0-and-1-1-in-azure-devops-services/

该项目的目的是简化过渡准备工作。我们收集了客户报告的最常见的 TLS 兼容性问题，并制作了一个脚本来检测这些问题并指导用户采取缓解措施。

运行脚本：

AzureDevOpsTls12Analysis.ps1

在 Powershell 版本 4 或更高版本中运行。仅适用于 Windows，该脚本已在 Windows Server 2012 R2 及更高版本上进行了测试。

该脚本的作用：

  • 通过打开与https://status.dev.azure.com的测试安全连接来执行探测。此站点需要 TLS 1.2 和强大的密码套件，在 TLS 1.0 和 1.1 协议弃用后，所有 Azure DevOps 站点也将如此。
    • 该探测器可以识别问题何时是网络连接或 DNS 解析问题，何时是由 TLS 不兼容引起。
    • 成功的探测证明操作系统允许 TLS 1.2 并且至少有一个所需的密码套件可用。这并不保证从该计算机连接到 Azure DevOps 的所有其他软件都能正常运行，不会出现 TLS 问题。
  • 通过查看选定的 Windows 注册表项来执行操作系统级别问题的分析，这些注册表项启用/禁用 TLS 1.2 协议并影响可用密码套件集。操作系统级配置由所有使用操作系统提供的 HTTPS/TLS 堆栈的软件共享。
  • 执行 .NET Framework 分析：检查 Windows 注册表中安装的 .NET Framework 版本和配置。
    • 查找是否存在注册表更改，这些更改使针对 4.7 之前的 .NET Framework 版本构建的 .NET 应用程序能够利用操作系统支持的 TLS 功能。如果没有这些更改，即使操作系统启用了 TLS 1.2，旧的 .NET 应用程序也将默认使用 TLS 1.0。
    • 如果您不打算在计算机上使用通过网络进行通信的旧版 .NET 程序，则无需应用这些程序。

脚本没有什么：

  • 该脚本本身不执行任何缓解措施。它仅打印缓解建议，其中包含文档文章的 URL 和要执行的步骤（要调用的 cmdlet 或要进行的注册表更改）。
  • 该脚本不需要提升权限即可运行。
  • 该脚本无法判断特定应用程序是否存在 TLS 问题。有些应用程序具有选择硬编码或配置的 TLS/SSL 版本。
