Conky 网络部分不报告 IP 或活动

Question

我最近买了一台翻新的 Thinkpad T430s 并安装了 Ubuntu Mate 16.04.3 LTS。我的定制之一是安装 conky 并下载一个.conkyrc可以为我提供运行性能监视器的软件 - cpu、RAM、HDD 和网络。

\n\n

这很棒，只是网络部分给出了一个骷髅图标并报告“无网络”。我知道我需要编辑.conkyrc-- 如何找到正确的 WLAN 名称以及需要将其插入何处？

\n\n

这是我现有的.conkyrc：

似乎只是为了迷惑用户，可能有许多不同的网络条目——很难确定这是否与硬件/驱动程序、Ubuntu 的确切版本或不太明智的东西有关。不幸的是，我们无法确定是否会找到 ETH0 或 WLAN0——但许多下载的脚本都会假设这一点。我必须为我的特定系统找到正确的 wifi 名称。谷歌搜索一下发现了这个命令：

$ nmcli dev status
DEVICE   TYPE      STATE        CONNECTION          
wlp3s0   wifi      connected    StokesCountyDEAvan4 
enp0s25  ethernet  unavailable  --                  
lo       loopback  unmanaged    -- 

此命令不需要超级用户权限，因此应该可供二级用户（甚至可能是来宾）访问。很容易看出，ETH0 或 ETH1 和 WLAN0 不在站点中。为了让我的 Conky 网络监视器部分正常工作，我所要做的就是用.conkyrcwlp3s0 替换 WLAN0，用 enp0s25 替换 ETH0（如果我通过有线以太网连接）。保存文件后，conky 重新启动，并开始实时正确报告我的网络状况和活动，就像 CPU 负载、RAM 使用情况和 HDD I/O 一样。
