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


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.
