1. Ping


The ping command is used to quickly start diagnosing network problems, find IP addresses of devices on the network, or even monitor your network speed.

ping -c 6 google.com

Command Ping -c 6 google.com


In the above command you can see the IP address that responded to the request along with the time it took to respond. The -c 6 option will limit the ping to six replies. If you decide to run the following command.

ping google.com

Ping will run indefinitely, until you decide to stop it. This can be done by pressing Ctrl + C on your keyboard.


The reason you want to let ping run for a long time could be to monitor the network connection between two devices. Or even between the computer and the internet. For this problem, you can run the following command:

ping -O google.com > dataping.txt


After you run this command, nothing seems to happen and your cursor will just blink continuously. However, two things happen in this command. There is an unlimited ping running and it is entering the output of the ping command to a file called dataping.txt in the same directory. This file can be opened and perform further investigation of the network.


Because by default the ping command will not appear when there is no reply. That's what the -O option is used for when you have unlimited pings running, and puts the output in a text file, and while it's running you unplug and reconnect the network cable several times. This will simulate the connection drop, and the connection increase again. To view the contents of a text file you can run the following command:

nanodataping.txt

ping -O google.com > dataping.txt


The above information displayed in the text file clearly shows where the network connection dropped. If you are experiencing strange network issues, this simple experiment can help you eliminate certain possibilities. For example, if you let a ping run against a device on your local network and there is no reply or response, but the same test of addresses on the internet shows some dropped packets. This could be a strong possibility that your computer hardware is fine, but internet-connected devices may need to be checked further.


2. Check IP Address


The ifconfig command is used to find the IP address of your device. But there are other commands that are cooler and full-featured. Here is the command:

ip address show

Show Linux IP Address Command


Obviously, this command shows you the IP address of each interface your device has. The Dab This will be the main command used to override ifconfig:

ip link set DEVICE down

ip link set DEVICE up

IP Link Command Set DEVICE Down Or Up


Similar to ifconfig DEVICE down or ifconfig DEVICE up you can set the state of your device up or down. Just replace DEVICE with the interface you want to change the status of.


3. Download Files From the Internet


Maybe when downloading a file on Windows, we should visit the site first and click on the download link. But on linux you can use the CLI to download the file, by using the curl or wget command, you can download the file easily.

curl -O https://www.openssl.org/source/openssl-1.0.2o.tar.gz

wget https://dl.google.com/linux/direct/google-chrome-stable_current_amd64.deb

Download Files in Linux CLI


Actually the above two commands will give you the same result. wget has a major strong side which is that it downloads recursively as opposed to curl . Although curl has more protocols supported namely FTP, FTPS, Gopher, HTTP, HTTPS, SCP, SFTP, TFTP, TELNET, DICT, LDAP, LDAPS, FILE, POP3, IMAP, SMB/CIFS, SMTP, RTMP, RTSP. While wget supports HTTP, HTTPS, and FTP.


4. Get a New IP Address


If you want to give up your IP address and issue a new one from the DHCP server, you can use the dhclient command:

dhclient device -r


Using dhclient with the -r option will release the dhcp IP Address first:

dhclient device


Omitting the -r option will have your DHCP issue you a new IP Address based on how it was configured.

Linux dhcpclient command


5. Get Information About Website


To get information about the website you can use the whois command. It is very useful to be able to view website records directly from the command line. To install whois run the following command:

apt-get update

apt-get install whois


After installing whois, you can ask any domain name to get more information:

whois monitortechnology.com


Whois Command In Linux CLI Conclusion


So that was the 5 Network Commands For Linux Terminal that can make it easier for you because text commands are more efficient for network problems than you have to click one by one.
