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：

1. 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。

2. 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。

3. 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>
4. 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。
