How to test network transfer rate in Linux using built-in tools or commands

In Linux, we can use some external tools or commands to test the network transmission speed. The following are some common methods:

1.Use ping command

The ping command can be used to test network latency and packet loss rate, but it cannot directly detect network transmission speed. We can indirectly measure network transmission speed by sending a large number of data packets and observing the transmission time.

ping s 1472 目标IP地址

This command will send a data packet with a size of 1472 bytes to the target IP address linux network delay test. By observing the return time, we can determine the network transmission speed.

2. Use iperf tool

iperf is a network performance testing tool that can be used to detect TCP and UDP bandwidth quality. It can report bandwidth, delay jitter and packet loss.

You need to install iperflinux training institution on your system. On Debian and Ubuntu, you can use the following command to install:

sudo aptget install iperf

On CentOS and RHEL, you can install using the following command:

sudo yum install iperf

You can run iperf on two machines to test the network transmission speed, one machine as the server and the other as the client.

Server side:

iperf s

Client:

iperf c 服务器IP地址

3. Use speedtestcli tool

speedtestcli is a lightweight command line tool written in Python for testing Internet connection speed. It can detect download rate, upload rate and latency.

You need to install speedtestclilinux network latency test on your system. On Debian and Ubuntu, you can use the following command to install it:

sudo aptget install speedtestcli

在CentOS和RHEL上，可以使用以下命令安装：

sudo yum install epelrelease
sudo yum install speedtestcli

你可以运行以下命令来测试网路传输速度：

speedtestcli

这个命令会显示你的下载速率、上传速率和延后。
