1 | # luci-app-bandwidthd
2 | 为OpenWRT上bandwidthd开发的luci配置页面,用于统计局域网各个IP的流量状况并绘图
3 |
4 | 简介
5 | ---
6 | 为编译[此固件][N]所需依赖包而写
7 |
8 | 可以方便的统计某个网卡上所有客户端的流量并绘图,还可以对不同类型的流量进行分类。
9 |
10 | 使用方法
11 | ---
12 | 1、首先使用ifconfig命令查看内网的地址和该地之对应的网卡,这里我配置的无线网段为192.168.2.1/24,网卡是eth0.2。
13 |
14 | 2、打开luci配置页面,在[被监控网卡]中填入第一步看到的网卡,被监控网段填入第一步观察到的网段
15 |
16 | 3、使用局域网的设备上网、看视频等等持续5分钟左右,打开192.168.2.1/bandwidthd查看(IP地址根据你的路由器地址确定),就可以看到每个设备的流量和图形统计结果了
17 |
18 | 
19 |
20 |
21 | 编译
22 | ---
23 |
24 | - 从 OpenWrt 的 [SDK][S] 编译
25 |
26 | ```bash
27 | # 以 ar71xx 平台为例
28 | tar xjf OpenWrt-SDK-ar71xx-for-linux-x86_64-gcc-4.8-linaro_uClibc-0.9.33.2.tar.bz2
29 | cd OpenWrt-SDK-ar71xx-*
30 | # 获取 Makefile
31 | git clone https://github.com/AlexZhuo/luci-app-bandwidthd.git package/luci-app-bandwidthd
32 | # 选择要编译的包 Luci -> Network -> luci-app-bandwidthd
33 | make menuconfig
34 | # 开始编译
35 | make package/luci-app-bandwidthd/compile V=99
36 | ```
