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
