百度：ubuntu14.04查看网速
ubuntu14.04查看网速
在Ubuntu 14.04中查看网速，你可以使用几种不同的方法。下面是一些常用的工具和命令：
- 使用iftop
iftop是一个基于文本的实时网络流量监控工具，它可以显示哪些主机正在使用你的网络带宽。
首先，你需要安装iftop：
sudo apt-get update
sudo apt-get install iftop
然后，运行iftop：
sudo iftop
这将显示实时的网络流量信息，包括发送和接收的流量。
- 使用nload
nload是另一个图形界面的实时网络流量监控工具，它可以显示网络接口的上传和下载速度。
安装nload：
sudo apt-get install nload
运行nload：
sudo nload
你将看到一个图形界面显示当前的网络活动。
- 使用vnstat
vnstat是一个基于文本的实时网络流量监控工具，它可以记录和显示历史网络使用情况。
安装vnstat：
sudo apt-get install vnstat
首次运行前，你需要创建一个数据库：
sudo vnstat -u -i <interface>
其中<interface>是你的网络接口名称（例如eth0或wlan0）。要查看网络流量，运行：
vnstat -i <interface>
或者查看历史数据：
vnstat -d -i <interface>
- 使用speedtest-cli
如果你想要测试你的互联网连接速度，可以使用speedtest-cli。这不是实时监控工具，但可以用来检查当前的下载和上传速度。
首先，安装speedtest-cli：
sudo apt-get install speedtest-cli
然后，运行测试：
speedtest-cli
这将显示你的下载速度、上传速度和延迟。
结论
选择哪种方法取决于你的具体需求：如果你需要实时监控网络流量，iftop或nload可能更适合；如果你需要查看历史网络使用情况，vnstat是一个好选择；而如果你只是想快速测试你的互联网速度，speedtest-cli会很有帮助。
