+
+Sometimes it is necessary to check the Internet connection speed from the server console.
+
+Use the following command to find out the Internet speed (download and upload) from the command line in Linux:
+
+```
+wget -O - https://raw.githubusercontent.com/sivel/speedtest-cli/master/speedtest.py | python
+```
+
+Example of the result of the command:
+
+```
+Retrieving speedtest.net configuration...
+Testing from Elisa telecommunications group, OU. (76.40.44.19)...
+Retrieving speedtest.net server list...
+Retrieving information for the selected server...
+Hosted by Compic OU (Tallinn, Estonia) [16.84 km]: 28.77 ms
+Testing download speed.........................
+Download: 93.30 Mbit/s
+Testing upload speed..........................
+Upload: 92.25 Mbit/s
+```
+
+If you plan to measure the bandwidth of the Internet channel frequently, you can install the script speedtest:
+
+```sh
+wget https://raw.github.com/sivel/speedtest-cli/master/speedtest.py
+chmod +x speedtest.py
+mv speedtest.py /usr/local/bin/speedtest
+```
+
+After installation, you will be able to check the Internet speed from the terminal, using the command `speedtest`
+
+Sometimes the utility mistakenly selects servers located at a great distance from us:
+
+```
+Retrieving speedtest.net configuration...
+Testing from Elisa telecommunications group, OU. (76.40.44.19)...
+Retrieving speedtest.net server list...
+Selecting best server based on ping...
+Hosted by Vodafone España (Alicante, Spain) [3415.53 km]: 112.947 ms
+Testing download speed................................................................................
+Download: 1.10 Mbit/s
+Testing upload speed................................................................................................
+Upload: 1.33 Mbit/s
+```
+
+Knowing that we are not currently in Spain, we can display a list of available servers with the command:
+- `speedtest --list | grep Tallinn` - search for servers in Tallinn or
+- `speedtest --list | more` - displays a list of available servers.
+
+Also, this mode can be useful if you want to know - at what speed a subscriber from another country will have access to your server.
