在我的 Ubuntu 23.04 系统上，systemd 将尝试在 systemd-networkd 启动网络桥之前启动 sshd

首先它报告：无法分配请求的地址

然后：br0: netdev 就绪

systemd-networkd[619]: br0: netdev ready

为什么 systemd 在执行 sshd 服务之前不等到桥接起来？

我的网络设备：

$ networkctl 
IDX LINK     TYPE     OPERATIONAL SETUP     
  1 lo       loopback carrier     unmanaged
  2 enp101s0 ether    enslaved    configured
  3 eno1     ether    enslaved    configured
  4 eno2     ether    routable    configured
  5 br0      bridge   routable    configured

我的网络配置了这个 netplan：

# Bridge config
network:
  version: 2
  renderer: networkd
  ethernets:
    # WAN port to cable modem.
    eno2:
      dhcp4: yes
      dhcp6: no
    # Currently not used.
    enx00242788156c:
      dhcp4: no
      dhcp6: no
    # LAN port to WAP
    eno1:
      dhcp4: no
      dhcp6: no
    # LAN port to switch.
    enp101s0:
      dhcp4: no
      dhcp6: no
  bridges:
    br0:
      interfaces:
        #- enx00242788156c
        - eno1
        - enp101s0
      addresses:
        - 10.1.0.1/16

注意：重新启动 sshd 服务会按预期工作，因为那时网桥可用。

我不再在我的系统中使用 FAN3。但是仍然为它设置了一个下/上传感器边界。我之前使用ipmitool进行了设置。

如何使用 ipmitool 将所有值设置回na而不是 0？

因为目前，较低的阈值会导致断言，并且所有粉丝都会全力以赴。

FAN1             | 1300.000   | RPM        | ok    | 100.000   | 200.000   | 300.000   | 3000.000  | 4000.000  | 5000.000  
FAN2             | na         |            | na    | na        | na        | na        | na        | na        | na        
FAN3             | 0.000      | RPM        | nr    | 0.000     | 0.000     | 0.000     | 3000.000  | 4000.000  | 5000.000  
FAN4             | na         |            | na    | na        | na        | na        | na        | na        | na        
FANA             | na         |            | na    | na        | na        | na        | na        | na        | na        
FANB             | 1300.000   | RPM        | ok    | 100.000   | 200.000   | 300.000   | 3000.000  | 4000.000  | 5000.000

我希望 FAN3像 FAN2、FAN4 和 FANA 一样读取na 。

我尝试过的事情：

  • $ sudo ipmitool sensor thresh FAN3 lower 0 0 0 （不停止断言）
  • $ sudo ipmitool sensor thresh FAN3 lower -1 -1 -1 （不接受）
  • $ sudo ipmitool sensor thresh FAN3 lower na na na （不接受）

这是在运行 Ubuntu 的 Microdata X11-SRM-F 上。

引起狂热粉丝的断言：

$ sudo ipmitool sel list
   1 | 09/30/2020 | 23:39:46 | Unknown #0xff |  | Asserted
   2 | 10/08/2020 | 17:38:54 | Fan #0x43 | Lower Critical going low  | Asserted
   3 | 10/08/2020 | 17:38:54 | Fan #0x43 | Lower Non-recoverable going low  | Asserted
   4 | 10/08/2020 | 17:43:50 | Fan #0x43 | Lower Critical going low  | Asserted
