Use the following command to Test Internet Download and Upload Speed from the Linux Command Line: $ wget -O - | python Test Download/Upload Internet Speed in Linux I’ll show how to simply check download/upload Internet speed to the geographically closest server, how to measure the network speed to specific server and how to share the results of speed test via .Īll these tasks can be performed using the Linux command line only. In this article you’ll find how to test Internet speed from the Linux terminal, using speedtest_cli – a simple command-line client written in Python for measuring Internet bandwidth by using infrastructure. Version 2, or (at your option) any later version.If you need to troubleshoot an issue with slow Internet access on your Linux system, it would be a good idea to measure the current Internet speed.

It is also unable to detect if the network is failing due to a local firewall policy been This program does not have super cow powers so it is unable to fix the errors by itself.

It also uses ping, hostĪnd nc (netcat) to do tests of the network connectivity and ensure that the host can (status of available interfaces and configured network routes). The program relies on the use of ip, netstat, ifconfig, arp and (when running as root)Įthtool or mii-tool, to obtain information about the system's networking configuration If the program is run as systemĪdministrator it will try to run some tools that are only available to it to speed up some However, the behaviour of the program when running as an unprivileged user is not the sameĪs running as system administrator (i.e. The program does not need special privileges to run as it does not do any system change.
