我的一个工作站（以前是 22.04.1 服务器版本，但根据 NUC 兼容性列表，最新的 BIOS 和 dbx EUFI 数据库升级迫使我降级到工作站，因为服务器版本在内核恐慌中循环（NUC 10i7FNH BIOS：59 UEFI dbx：267。详情如下：

该“多宿主无头工作站”通过 netplan 配置了绑定和 VLAN，并且它应该运行 sshd 来监听它的某些（并非全部）接口。
192.16.0.150/24 (for admin only from admin vlan) port 22
10.0.1.150/24 (key users from lab 1 vlan) port 22
10.0.2.150/24 (key users from lab 2 vlan) port 22
10.0.3.150/24 (key users from lab 3 vlan) port 22
10.0.4.150/24 (key users from lab 4 vlan) port 22
other vlans (storage, backup, data/application, etc.) are supposed to be without users that need to get a ssh connection.
安装 sshd 之后，无需定制 sshd_config，一切正常，所有接口都可以获得其 sshd 监听器，甚至那些应该提供存储/备份或应用程序流的接口也是如此......
我已经进行了几次测试（有或没有端口设置）。
使用端口设置进行测试：
ListenAddress 192.168.0.200:22
ListenAddress 10.0.1.200:22
ListenAddress 10.0.2.200:22
ListenAddress 10.0.3.200:22
ListenAddress 10.0.4.200:22
不设置端口测试：
ListenAddress 192.168.0.200
ListenAddress 10.0.1.200
ListenAddress 10.0.2.200
ListenAddress 10.0.3.200
ListenAddress 10.0.4.200
我运行的所有明确指定了 ListenerAddress 的测试都遇到了同样的问题。systemctl 注意到服务降级：sshd 在系统启动时（引导或重启后）显示失败状态，但 systemctl restart ssh.service 会在下次重启前修复该问题。

有人能解释一下这是什么问题吗？

非常感谢 Andrew，我已将注意到的第一个选项应用到您的网址中。

没关系！
