Uwe Pfeifer's questions

我的 LAN 连接未连接。我有一个新的路由器。因为那个 Ubuntu 不会连接。有任何想法吗？在 Windows 10 上，LAN 连接有效。IPv6 似乎工作。只是不是 IPv4。

编辑：这是德国电信的 Smart 3。一切都适用于旧路由器。我无法附上图片，所以已将其上传到我的下一个大声。链接：屏幕图片 我也尝试重新启动，重新安装后我仍然遇到同样的问题。另外我认为问题是由 dhcp 违规引起的。

编辑#2：它通过以太网电缆连接。它在 Windows 下工作。一切都正确连接。路由器管理界面的阻止列表中没有任何内容。我什至无法通过 IPv4 访问 LAN。所以问题是通过 DHCP 获取 LAN IPv4。

编辑#3：网卡 PC 使用以太网 LAN 电缆连接到路由器 LAN。路由器使用普通电话线连接到外部。这是一个IP电话路由器。好吧，所有的 LED 都是白色的（没问题）。我的笔记本电脑 (wlan) 可以访问互联网并为 LAN 获取 IPv4。ifconfig 默认情况下没有安装，我无法访问互联网，所以我不能给你命令的输出。我只能说，IPv6 有效，IPv4 无效。

编辑#4：我无法向您发送标签屏幕截图。虽然一切都是默认和自动的。我无法 ping 8.8.8.8 - 网络无法访问。这里是命令的屏幕截图：第二个屏幕截图

编辑#5：这里是截图。我使用手机应用程序在这里交谈。无法在设备之间交换剪贴板。第三张截图我在某处读到它试图获取 IP 但它违反了某些协议。与 nxdomain 或其他东西有关。

编辑：调试日志不存在。这是来自 Windows 的屏幕截图。截屏

我正在尝试通过我的 vpn 路由互联网流量。我已经使用教程设置了所有内容。现在，我听说 OpenVPN 只能处理 ipv4 或 ipv6。所以我想坚持使用ipv4。我在我的电脑上的网络管理器中禁用了 ipv6，但现在，ipv6 网站仍然通过 ipv6 发送而没有 VPN。我怎样才能防止这种情况？

谢谢！！:)

我安装了 GitLab Omnibus 包。我现在想使用 Plesk 的 nginx 而不是打包的 nginx。我已将配置设置为不使用捆绑的 nginx。

现在我想使用 Plesk Onyx 的 nginx 来处理对 gitlab 的请求。如何配置 ngingx plesk 来执行此操作（Vhost？）？

我添加了以下内容：

即使我已经删除了监听选项的 default_server 部分。

如果有人可以帮助我，我将不胜感激。

非常感谢！怪异的。

我有以下输出，我的 ubuntu 启动速度非常慢。启动需要大约 2-3 分钟，而 Windows 只需要 15 秒。这里是 journalctl 的输出：http: //paste.ubuntu.com/24706296/

如果有人可以帮助我，那就太好了，因为我真的很想快速启动到 ubuntu。

我在 SSD (/) 上有所有东西，但在硬盘上只有 /var 和 /home。
