If you prefer command line utilities, managing WiFi can be a real pain. Well, it doesn't have to be. - -wpa_supplicant can be used as a command line utility. You can actually set it up easily with a simple configuration file. - -### Scan For Your Network - -If you already know your network information, you can skip this step. If not, its a good way to figure out some info about the network you're connecting to. - -wpa_supplicant comes with a tool called `wpa_cli` which provides a command line interface to manage your WiFi connections. You can actually use it to set up everything, but setting up a configuration file seems a bit easier. - -Run `wpa_cli` with root privileges, then scan for networks. -``` - -# wpa_cli -> scan - -``` - -The scan will take a couple of minutes, and show you the networks in your area. Notate the one you want to connect to. Type `quit` to exit. - -### Generate a Block and Encrypt Your Password - -There's an even more convenient utility that you can use to begin setting up your configuration file. It takes the name of your network and the password and creates a file with a configuration block for that network with the password encrypted, so it's not stored in plain text. -``` - -# wpa_passphrase networkname password > /etc/wpa_supplicant/wpa_supplicant.conf - -``` - -### Tailor Your Configuration - -Now, you have a configuration file located at `/etc/wpa_supplicant/wpa_supplicant.conf`. It's not much, just the network block with your network name and password, but you can build it out from there. - -Your file up in your favorite editor, and start by deleting the commented out password line. Then, add the following line to the top of the configuration. -``` -ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=wheel - -``` - -It just lets users in the `wheel` group manage wpa_supplicant. It can be convenient. - -Add the rest of this to the network block itself. - -If you're connecting to a hidden network, you can add the following line to tell wpa_supplicant to scan it first. -``` -scan_ssid=1 - -``` - -Next, set the protocol and key management settings. These settings correspond to WPA2. -``` -proto=RSN -key_mgmt=WPA-PSK - -``` - -The group and pairwise settings tell wpa_supplicant if you're using CCMP, TKIP, or both. For best security, you should only be using CCMP. -``` -group=CCMP -pairwise=CCMP - -``` - -Finally, set the priority of the network. Higher values will connect first. -``` -priority=10 - -``` - - -![Complete WPA_Supplicant Settings][1] -Save your configuration and restart wpa_supplicant for the changes to take effect. - -### Closing Thoughts - -Certainly, this method isn't the best for configuring wireless networks on-the-fly, but it works very well for the networks that you connect to on a regular basis. - - --------------------------------------------------------------------------------- - -via: https://linuxconfig.org/connect-to-wifi-from-the-linux-command-line - -作者：[Nick Congleton][a] -译者：[lujun9972](https://github.com/lujun9972) -校对：[校对者ID](https://github.com/校对者ID) - -本文由 [LCTT](https://github.com/LCTT/TranslateProject) 原创编译，[Linux中国](https://linux.cn/) 荣誉推出 - -[a]:https://linuxconfig.org -[1]:https://linuxconfig.org/images/wpa-cli-config.jpg diff --git a/translated/tech/20171002 Connect To Wifi From The Linux Command Line.md b/translated/tech/20171002 Connect To Wifi From The Linux Command Line.md new file mode 100644 index 0000000000..50c25bd839 --- /dev/null +++ b/translated/tech/20171002 Connect To Wifi From The Linux Command Line.md @@ -0,0 +1,109 @@ +通过 Linux 命令行连接 Wifi +====== + +目标：仅使用命令行工具来配置 WiFi + +发行版：适用主流的那些发行版 + +要求：安装了无线网卡的 Linux 并且拥有 root 权限。 + +难度：简单 + +约定： + +* `#` - 需要使用 root 权限来执行指定命令，可以直接使用 root 用户来执行，也可以使用 `sudo` 命令 +* `$` - 可以使用普通用户来执行指定命令 + + +### 简介 + +许多人喜欢用图形化的工具来管理电脑，但也有很多人不喜欢这样做。如果你比较喜欢命令行工具，管理 WiFi 会是件很痛苦的事情。然而，事情本不该如此。 + +wpa_supplicant 可以作为命令行工具来用。使用一个简单的配置文件就可以很容易设置号 WiFi。 + +### 扫描网络 + +若你已经知道了网络的信息，就可以跳过这一步。如果不了解的话，则这是一个找出网络信息的好方法。 + +wpa_supplicant 中有一个工具叫做 `wpa_cli`，它提供了一个命令行接口来管理你的 WiFi 连接。事实上你可以用它来设置任何东西，但是设置一个配置文件看起来要更容易一些。 + +使用 root 权限运行 `wpa_cli`，然后扫描网络。 +``` + +# wpa_cli +> scan + +``` + +扫描过程要花上一点时间，并且会显示所在区域的那些网络。记住你想要连接的那个网络。然后输入 `quit` 退出。 + +### 生成配置块并且加密你的密码 + +还有更方便的工具可以用来设置配置文件。它接受网络名称和密码作为参数，然后生成一个包含该网路配置块(其中的密码被加密处理了)的配置文件。 +``` + +# wpa_passphrase networkname password > /etc/wpa_supplicant/wpa_supplicant.conf + +``` + +### 裁剪你的配置 + +现在你已经有了一个配置文件了，这个配置文件就是 `/etc/wpa_supplicant/wpa_supplicant.conf`。其中的内容并不多，只有一个网络块，其中有网络名称和密码，不过你可以在此基础上对它进行修改。 + +用喜欢的编辑器打开该文件，首先删掉说明密码的那行注释。然后，将下面行加到配置最上方。 +``` +ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=wheel + +``` + +这一行只是让 `wheel` 组中的用户可以管理 wpa_supplicant。这会方便很多。 + +其他的内容则添加到网络块中。 + +如果你要连接到一个隐藏网络，你可以添加下面行来通知 wpa_supplicant 先扫描该网络。 +``` +scan_ssid=1 + +``` + +下一步，设置协议以及密钥管理方面的配置。下面这些是 WPA2 相关的配置。 +``` +proto=RSN +key_mgmt=WPA-PSK + +``` + +group 和 pairwise 配置告诉 wpa_supplicant 你是否使用了 CCMP，TKIP，或者两者都用到了。为了安全考虑，你应该只用 CCMP。 +``` +group=CCMP +pairwise=CCMP + +``` + +最后，设置网络优先级。越高的值越会优先连接。 +``` +priority=10 + +``` + +![Complete WPA_Supplicant Settings][1] + +保存配置然后重启 wpa_supplicant 来让改动生效。 + +### 结语 + +当然，该方法并不是用于即时配置无线网络的最好方法，但对于定期连接的网络来说，这种方法非常有效。 + + +-------------------------------------------------------------------------------- + +via: https://linuxconfig.org/connect-to-wifi-from-the-linux-command-line + +作者：[Nick Congleton][a] +译者：[lujun9972](https://github.com/lujun9972) +校对：[校对者ID](https://github.com/校对者ID) + +本文由 [LCTT](https://github.com/LCTT/TranslateProject) 原创编译，[Linux中国](https://linux.cn/) 荣誉推出 + +[a]:https://linuxconfig.org +[1]:https://linuxconfig.org/images/wpa-cli-config.jpg
