我有一台装有 OpenMediaVault 的服务器（运行在 Debian 上），它已为我的家庭网络配置，但我搬到了一个新地方，那里有新的路由器和新的网络（路由器设置为使用 DHCP 分配 IP）。我在服务器上插入了一根以太网电缆，但它仍然使用旧设置，我无法在当前网络上找到它（路由器也看不到它已连接）。
我尝试重新启动它并尝试告诉它获取新的配置，但我不那么精明而且我不记得我到底做了什么（抱歉，一直很忙乱）。
我可以物理访问它，它有一个键盘和显示器，这就是我目前与它交互的方式。
这是我的nano /etc/resolv.conf输出（根据我在屏幕上看到的内容手写输入）：
# This file is managed by man:systemd-resolved(8). Do not edit.
#
# This is a dynamic resolv.conf file for connecting local clients directly to
# all known uplink DNS servers. This file lists all condigured search domains.
#
# Third party programs must not access this file directly, but only through the
# symlink at /etc/resolv.conf. To manage man:resolv.conf(5) in a different way,
# replace this symlink by a static file or a different symlink.
#
# See man:systemd-resolved.service(8) for details about the supported modes of
# operation for /etc/resolv.conf.
nameserver 1.1.1.1
这是我的nano /etc/network/interfaces输出（根据我在屏幕上看到的内容手写输入）：
# This file is auto-generated by openmediavault (https://www.openmediavault.org)
# WARNING: Do not edit this file, your changes will get lost.
# interfaces(5) file used by ifup(8) and ifdown(8)
