Linux 网络限速 Wondershaper 工具使用

wondershaper 可以限制 linux 服务器网卡级别的带宽

下载 wondershaper

# cd /usr/local/
# git clone  https://github.com/magnific0/wondershaper.git

wondershaper 使用

// 单位是 Kbps
./wondershaper -a 网口名称 -u 上传速度 -d 下载速度

// 限制 eth0 网口上传下载为 150  Kbps
./wondershaper -a eth0 -u 150 -d 150

// 可以看到多了一个 ifb0 网口
