我在一台新电脑上安装了 Ubuntu 24.04.2 LTS，但遇到了蓝牙适配器的问题。系统检测到了蓝牙适配器，并且显示已开启，但却无法发现附近的任何蓝牙设备。

以下是相关的系统和诊断信息：

操作系统：Ubuntu 24.04.2 LTS 内核版本：6.11.0-24-generic 蓝牙适配器：IMC Networks 蓝牙无线电（USB ID 13d3:3600）

bluetoothctl scan on 行为：当我在 bluetoothctl 中运行 scan on 时，该命令执行并开始发现，但它没有列出任何附近的蓝牙设备。

有人能帮我确定我需要安装哪个驱动程序吗？这是在一台华硕 ROG700 预装电脑上。

我正在尝试使用 Ubuntu 服务器扫描可用的 Wi-Fi 网络。我尝试在不安装任何第三方软件包的情况下完成此操作。

据我所知，在 Ubuntu Server 的安装过程中，向导会建议它找到的一些可用网络，但我不知道它在 ISO 中使用什么程序来执行此操作。

  1. 不安装任何额外的包可以做到这一点吗？
  2. 如果没有，我可以安装什么软件包来进行快速扫描？（请注意，我想避免使用 NetworkManager 并继续使用默认的 systemd-networkd）

我们的安全扫描程序显示，当前内核 5.15.0-134-generic 版本存在漏洞。因此我进行了升级，结果网络连接严重中断。服务器启动后甚至无法识别网络接口。这是一台戴尔 Poweredge r710（我知道它很老了）。我只是想让它继续运行。“IP 地址”根本没有列出以太网卡，但显示了其他网络设备。

我唯一能想到的可能是新内核才发布一周，可能还没有更新相同的驱动程序？如果我回滚内核，网卡就能立即恢复连接。我尝试插入一个 USB 适配器，但它也检测不到，所以缺少的硬件支持并不仅限于网卡接口。我们还安装了一张 10Gb 光纤卡，它仍然可以在两个内核上运行。我以前从未遇到过这种情况。大家有什么想法或可行的解决方案吗？

简而言之：我在 9000 端口上运行着一个服务，我可以通过 Go 应用程序在本地 (127.0.0.1:9000) 连接到它，但无法从另一台机器 (192.168.0.136:9000) 连接到它。两台电脑之间可以 ping 通，而且 UFW 中的 9000 端口是开放的。

编辑 1：即使我禁用 UFW，也无法访问该服务。

我是 Linux 和网络新手。我有一台运行 Ubuntu 24.04.2.LTS 的笔记本电脑，它通过 Wi-Fi 连接到我的家用路由器。我还有一台 Windows 11 台式机（通过以太网）连接到同一个路由器。

在 Ubuntu 上运行 ifconfig 得到：（我只复制了我认为相关的部分）

wlp0s20f3: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500
        inet 192.168.0.136  netmask 255.255.255.0  broadcast 192.168.0.255

        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0

在 Windows 上运行 ipconfg 会得到：（我只复制了我认为相关的部分）

   Default Gateway . . . . . . . . . : 192.168.0.1

我的 Ubuntu 笔记本电脑上运行着Clickhouse服务，我正尝试通过 Windows 桌面上运行的 Go 应用程序访问它。我不断收到错误：panic: dial tcp 192.168.0.136:9000: connectex: 无法建立连接，因为目标计算机主动拒绝了它。

我确信Clickhouse 在 9000 端口上运行正常，因为我在 Ubuntu 笔记本上直接运行 Go 代码时能够连接到它。两种情况下的 conn 字符串都可以在这里找到。

我可以从 Ubuntu 电脑 ping 通 Windows 电脑，反之亦然。但是，我无法从 Windows 电脑 ping 通端口 9000。我在 Windows 上使用 PsTools 中的 PsPing。

我已经验证了 UFW 中的端口已打开：netstat -tulpn

如何从我的 Windows 计算机访问此 Clickhouse 服务？

编辑

  • 2025-03-15：我的问题与此问题不同，原因如下：
    • 我的内核是6.11.0-19-generic，它比解决该用户问题的内核更新。
    • 与该用户不同，当我运行sudo dmesg | grep wcn或时sudo dmesg | grep ath，什么都没有出现。
    • 我的机器的wifi在网络设置中可见。

概括

我最近用微星 MPG X870E Carbon WiFi 主板安装了一台 Windows 11 / Ubuntu 24 双系统。我的 WiFi 连接通常直接通过主板，无需外部适配器。在这两种操作系统上，WiFi 速度通常都比同一网络上其他低规格设备慢。

在排除此故障时，我运行了iwconfig，结果返回：

lo        no wireless extensions.

enp9s0    no wireless extensions.

enp10s0   no wireless extensions.

wlp17s0   no wireless extensions.

我觉得很奇怪。既然我能用网络（虽然网速很慢），难道不应该在这里看到一些结果吗？

上一个问题

我之前将这台机器设置为 Windows 11 / Linux Mint 22 系统，期间遇到了完全没有 WiFi 的问题。我在这里获得了帮助。自从用 Ubuntu 替换 Linux Mint 后，我​​仍然有时会发现从 Ubuntu 重启到 Windows 11 后没有 WiFi，但只需重启机器即可解决。

我正在使用 Ubuntu 桌面。当我想使用 ssh 连接到 Ubuntu 桌面时，我想使用主机名而不是 IP 地址。这将使连接到该设备变得更容易，因为 IP 可以在重启后更改。

所以现在我需要运行：

ssh [email protected]

不过我想要这样的东西：

ssh [email protected]

你知道如何为我的 ubuntu 桌面分配主机名吗？

我有一个全新安装的 Ubuntu 服务器 24.04，带有 5 个 NIC。

第一个是 DHCP，实际上并未使用，其他 4 个将用作 Pi-hole 接口。

我尝试了以下配置。我可以通过 SSH 访问这些 IP 地址，但在分配静态 IP 地址后我无法导航到互联网。

我的配置中是否缺少了某些内容？我是否需要配置其他内容才能使其正常工作？

eno1目前未连接到任何网络。ip route显示以下内容：

10.2.142.0/24 dev enp6s0 proto kernel scope link src
10.2.142.2 10.2.142.0/24 via 10.2.142.254 dev enp6s0 proto static

172.1.0.2 172.1.0.0/24 via 172.1.0.1 dev enp5s0 proto static

所有接口都连接到不同的路由器，这些路由器具有不同的 ISP 和互联网接入。

抱歉反馈迟了，我最近才检查了这些配置，看起来路由表确实丢失了，谢谢

我没有有线网络连接，在带有 GIGABYTE X870 EAGLE WIFI7（AM5、DDR5、M.2 PCIe 5.0、Wi-Fi 7）主板的新系统上运行 Ubuntu 24.04。

蓝牙似乎可用，但设置中的蓝牙“对话”找不到任何设备，尽管我正在输入此信息的手机已启用蓝牙。

安装期间没有网络。所以我运行的是 24.04.1 附带的版本 - 没有进行任何更新。

新机器上安装了 Windows 11，并且有连接，所以我猜硬件没有问题。

帮助。

从今天起，我的 Thunderbird 128.7 无法连接到任何基于 IMAP 的电子邮件提供商，提示连接将被拒绝。我尝试重新安装 thunderbird，但无济于事。

我认为问题可能出在 OpenSSL，但不确定：

（尽管“长度 0”让我感到困惑）

这似乎不是 OpenSSL 本身的问题，因为它可以很好地连接到 https：

$ openssl s_client -connect www.gmx.net:443
CONNECTED(00000003)
[...]

gnutls 也无法连接 IMAP：

gnutls-cli -s imap.gmx.de -p 993
Processed 146 CA certificate(s).

Connecting to '212.227.17.186:993'...
Could not connect to 212.227.17.186:993: Connection refused

在 GnuTLS 和多个其他 IMAP 服务器也出现故障后，我怀疑是防火墙问题，但我不知道有防火墙，但iptables我没有更改 iptables 配置，嗯。有什么想法可以调试这个问题吗？
