Linux下按程序查实时流量 network traffic

实然看到下载速度多达几M/s,但实际上并没有什么占用带宽的进程.

相查看每个程序占用的网络流量, 但系统自带的 System Monitor 只能查看全局的流量, 不能具体看某个程序的......

key words: network traffic, process specific, nethogs

工具: nethogs (要用sudo运行)

Description : NetHogs is a small "net top" tool.　　　　　　　　/* 像top 一样的工具, 实时更新 */
            :
            : Instead of breaking the traffic down per protocol or per subnet, like
            : most such tools do, it groups bandwidth by process and does not rely　　　　/* process specfific */
            : on a special kernel module to be loaded.
            :
            : So if there's suddenly a lot of network traffic, you can fire up　　　　　　　　/* 用于发现占用带宽的进程, 杀了它 */
            : NetHogs and immediately see which PID is causing this, and if it's
            : some kind of spinning process, kill it.

$ sudo dnf install nethogs -y

nethogs 的交互命令

m: 切换单位 KB/sec, KB, B, MB

r: 按接收排序 receive

s: 按发送排序 send
