Information

In some cases, it is necessary to check network connection performance between two Linux-based hosts, for example, to validate traffic shaping settings.

The simplest way to do this is to use netcat.

On server machine:

~# nc -l 1122 > /dev/null

On client machine:

~# dd if=/dev/zero bs=9100004096 count=1 | nc <SERVER_MACHINE_IP> 1122

As a result, a similar message will be displayed:

2147479552 bytes (2.1 GB) copied, 46.8923 s, 45.8 MB/s

NOTE: It is necessary to set count=1 because after the first portion, netcat will quit.
