Linux servers were very useful these days, just as it is very easy to register with Linux servers, and it is very easy to use them as well.
A Linux server is a server that is run by the Linux Open Source operating system. It offers businesses an affordable option to deliver content, applications, and services to their customers.
Since Linux is open source, users also benefit from a strong community of resources and followers. Each variation of Linux server is designed with different uses :
If you have a web server running, most likely CentOS® is running.
If your application serves thousands of users or even more, the solution you will be looking for will be designed to support this type of volumes such as Red Hat® Enterprise or Ubuntu® Server.
That would be overkill for your business needs as a turnkey Linux server would suffice for a specific purpose. The cloud infrastructure is typically Linux based.
Although we can use a Linux distribution for our server (eg Ubuntu) if we wish, Linux server distributions are slightly different from desktop distributions.
For example, server versions are usually much smaller than desktop versions for each administrator to customize to their liking, they usually do not have a graphical interface by default to save resources and have optimizations and features designed to offer the highest performance, greatest stability and the best possible security.
One of the better features of Linux is Keylogger because it helps us optimize and know what’s going on when we’re not at the computer.
You may want to know if anyone has used your computer while you were away and see what the classes were doing. How do I install a keylogger for Linux?
A keylogger is a hardware device or software that silently records every keyboard input (key) made by the user.
It can be used as a bidding tool to keep track of what you write and does not lose anything you have done or saved on your computer, but it should be noted that some bad people also use it for illegal purposes like malware spyware and sending this information to third parties.

2 Easy Ways to Format Flashdisk on Ubuntu Linux, which method do you choose?
Flash format is an activity that aims to empty the files stored in it. This method is done for various reasons, such as wanting to copy new files, removing viruses, and others.
Flash format in Linux is not much different from the flash format in Windows, and it’s just that there are various ways of formatting that you can do. Depending on your understanding of which one is easy, you can use your method.
In this discussion, I will use two of the most common and easy-to-use ways to format a flash drive on Linux, namely how to format a flash drive manually and via the Terminal. The Type of Linux that I use here is the desktop version of Ubuntu 16.04.
How to Format Flashdisk on Linux Ubuntu
( I. ) Format Flash Disk Manually
The one most often used by users is how to format the flash here manually I use. The steps are as follows.
1. Open your file explorer or directory. Click on the flash drive that you want to format to see if your flash drive is legible, what it contains, and are you sure you want to format it.
2. After that, right-click on your flash device, as shown in the picture—Click Format to empty your flash.
3. Next, there are options ( Erase, Type, and Format ) that you can adjust to your needs on this Volume Format. You can follow the default options as shown in the picture.
- I select ‘ Don’t overwrite existing data (Quick )’ in the Erase section. This option makes the formatting process faster.
- I choose the FAT format for Type here, but you can select another such as NTFS.
- Then, write a new name for your flash device in the Name field.
- Next, click the Format button.
4. After that, a confirmation will appear again to make sure you do the correct format of the flash. At this stage, the Type of your flash device will be displayed as indicated by the arrow in the image. The flash that I formatted is branded HP and has a capacity of 16GB. Click the Format button to start the flash format process.
5. Format your flash drive has been successful. You can check it by re-opening your flash directory and seeing that the flash drive is empty.
( II. ) Format the flash drive via Terminal.
In addition to manually, you can format the flash via the Terminal. How to? Follow these steps.
1. First, you can check the contents of your flash drive first to make sure you format it. Here, the name of my flash is My FD.
2. Open your Terminal. You can use the shortcut by pressing the keyboard’s Ctrl + Alt + T keys. Type the command:
sudo fdisk -l
The above command aims to find out the address of your flash drive. In the command, use the word sudo, where the Terminal will ask for your password input first. Enter your password; then, the Terminal will display the specifications of the device installed on your computer.
The device that is connected is the flash that we will format. You can ensure the device is your flash drive by observing its size. The example image above says 15.1 G, which means that the flash that I will format is filled with 15.1 GB. Then, remember the address. The address is listed in the Device column, wherein the image above it says /dev/sdb1.
3. Next, use the flash address we know earlier to run the umount command. This command aims to release the flash that is currently associated. You can see the related flash disk in the file explorer, wherein the flash name has an arrow button, as shown below.
Use the command below to remove your pen drive.
sudo umount /dev/sdb1
4. Next, you can type a command like the one below to format the flash drive.
sudo mkfs.vfat /dev/sdb1
There is the word ‘ vfat ‘ in the command where FAT states the flash format after formatting. You can replace it with NTFS, hfs, ext2, ext3, ext4, and others according to your needs.
5. Finally, your flash is successfully formatted. To check, please open your file explorer and prove your flash drive is empty.
Before formatting the flash drive, make sure there are no important files that will be deleted. Back up your precious data if you are worried about losing your files. That’s how to format the flash on Linux Ubuntu easily. Give your feedback in the comments column below. Thank you.

Step 2. Please download the Installer file from Microsoft Teams; please adjust it to the Linux distro you have, DEB for Ubuntu, Debian and all their descendants, and RPM for Fedora, CentOS and all their siblings.
