如何建立与 Sierra Wireless MC7354 的 WWAN 的 IP 连接？

我有一个带有运行 Ubuntu 18.04的Sierra Wireless MC7354 调制解调器的系统。

ModemManager 可以查看和控制调制解调器。

$ mmcli --modem 0

返回大量重要信息。（这就是我知道调制解调器是 MC7354 的原因。）

/org/freedesktop/ModemManager1/Modem/0 (device id '232972a04adf83122a392fd83b274431de596ebd')
  -------------------------
  Hardware |   manufacturer: 'Sierra Wireless, Incorporated'
           |          model: 'MC7354'
           |

端口列表显示了几个端口：

ports: 'ttyUSB0 (qcdm), wwp0s20u5i8 (net), wwp0s20u5i10 (net), cdc-wdm0 (qmi), cdc-wdm1 (qmi), ttyUSB2 (at)'

$ mmcli --modem 0 --simple-connect="apn=internet"

是成功的

$ mmcli --bearer 0
Bearer '/org/freedesktop/ModemManager1/Bearer/0'
  -------------------------
  Status             |   connected: 'yes'
                     |   suspended: 'no'
                     |   interface: 'wwp0s20u5i8'
                     |  IP timeout: '20'

                     |  gateway: '100.232.81.141'
                     |      DNS: '10.177.0.34', '10.177.0.210'
                     |      MTU: '1430'
  -------------------------

                     | Bytes transmitted: 'N/A'

显示调制解调器已连接到互联网 (?)。

如何在 Ubuntu 上建立连接以使用此界面？

$ ifconfig -a

如何建立与此设备的 IP 连接？

谢谢您的帮助！

    我想你仍然想知道。

    如何建立与 Sierra Wireless MC7354 的 WWAN 的 IP 连接？

    你已经这样做了：

    $ mmcli --bearer 0

Bearer '/org/freedesktop/ModemManager1/Bearer/0'
  -------------------------
  Status             |   connected: 'yes'

    所以基本上剩下的就是用给定的 IP 和网络掩码设置适当的 WWAN 接口。但是，您还必须将要通过接口的流量路由到定义的网关。

    您可能应该阅读服务器指南中第 43 页左右的整个部分。 请注意，如果您使用 netplan，它会搞砸您，例如，它将忽略您手动添加的网络管理器连接。

      IPv4 configuration 
                 |   method: 'static'
                 |  address: '100.232.81.142'
                 |   prefix: '30'
                 |  gateway: '100.232.81.141'
                 |      DNS: '10.177.0.34', '10.177.0.210'
                 |      MTU: '1430'

    它说静态无关紧要，仅意味着只要承载保持连接，您就会拥有该IP。除非您为静态 IP 付费，否则当您重新连接承载时，ISP 很可能会给您一个新 IP。

    您收到的设置很可能基于您连接的 APN。

    依赖于 ISP，他们也可以强制使用他们的 dns。

    所以，我的问题是，当您至少有一个易于使用的网络管理器可以处理它时，为什么还要手动执行此操作？

Description: network management framework (daemon and userspace tools)
 NetworkManager is a system network service that manages your network devices
 and connections, attempting to keep active network connectivity when
 available. It manages ethernet, WiFi, mobile broadband (WWAN), and PPPoE
 devices, and provides VPN integration with a variety of different VPN
 services.
 .
 This package provides the userspace daemons and a command line interface to
 interact with NetworkManager.
 .
 Optional dependencies:
  * avahi-autoipd: Used for IPv4LL, a protocol for automatic Link-Local IP
    address configuration.
  * ppp: Required for establishing dial-up connections (e.g. via GSM).
  * dnsmasq-base/iptables: Required for creating Ad-hoc connections and
    connection sharing.
  * libteam-utils: Network Team driver allows multiple network interfaces to be
    teamed together and act like a single one. This process is called "ethernet
    bonding", "channel teaming" or "link aggregation".

    如果您阅读了上面的内容，它并不是需要桌面的任何地方，实际上它正好相反，桌面将完全拉入它以完成网络部分。

    所以我的建议还是一样，安装网络管理器。

    如果您已经使用了任何其他网络管理器，例如 networkd，只需将 network-manager 配置为仅配置 wwan。

    这可以通过编辑来完成/etc/NetworkManager/conf.d/10-globally-managed-devices.conf

    unmanaged-devices=*,except:type:wwan,except:type:gsm

    要设置连接，您可以使用nmcli或手动创建配置：

    sudo vim /etc/NetworkManager/system-connections/myisp

    [connection]
id=myisp
uuid=755d5082-e2e3-4691-873a-0669b27aaaa2
type=gsm
interface-name=cdc-wdm0
permissions=
timestamp=1547308598

[gsm]
apn=internet.public
number=*99#

[ipv4]
dns=8.8.8.8;8.8.4.4;1.1.1.1;
dns-search=
ignore-auto-dns=true
method=auto

[ipv6]
addr-gen-mode=stable-privacy
dns-search=
method=auto

    希望这将引导您朝着正确的方向前进，最良好的祝愿:)
