如何设置网络管理器服务来自动配置调制解调器连接？

Question

我尝试在 Ubuntu 18.04 上连接 USB Huawei E8372 调制解调器。 dmesg命令给出一个信息：

[  371.616615] cdc_ether 1-6:1.0 eth0: register 'cdc_ether' at usb-0000:00:14.0-6, CDC Ethernet Device, 0c:5b:8f:27:9a:64

[  372.637965] sd 4:0:0:0: [sdc] Attached SCSI removable disk

[  372.860310] usbcore: registered new interface driver option
[  372.860325] usbserial: USB Serial support registered for GSM modem (1-port)

所以我有 enx0c5b8f279a64 界面。网络管理器服务添加此设备（来自 service network-manager status 的日志）：

[1561201979.1919] devices added (path: /sys/devices/pci0000:00/0000:00:14.0/usb1/1-6/1-6:1.0/net/enx0c5b8f279a64, iface: enx0c5b8f279a64)

但是我不能上网。而且，ifconfig不显示这个界面。

我可以使用 dhclient: dhclient -v enx0c5b8f279a64:

Listening on LPF/enx0c5b8f279a64/0c:5b:8f:27:9a:64

DHCPACK of 192.168.8.100 from 192.168.8.1

之后上网，network-manager日志：

[1561202049.0339] device (enx0c5b8f279a64): carrier: link connected
[1561202049.0415] device (enx0c5b8f279a64): carrier: link connected

我希望网络管理器服务自动设置调制解调器的接口，而不需要像运行 dhclient 这样的任何手动步骤。怎么做？

谢谢。

在 ubuntu 中使用 18.04 netplan，只需为您的接口编写 enx0c5b8f279a64："dhcp: true"”（参见此处示例：https://netplan.io/examples）
