When you're working with files on your local machine and need to transfer them to a server, you can use secure and efficient tools like scp (secure copy) or rsync. These commands are simple to use and can make file transfer processes seamless, whether you're working on an Ubuntu or CentOS server.

Step 1: Install Necessary Tools

Both scp and rsync come pre-installed on most Linux distributions. However, if they're not installed, you can easily install them.

For Ubuntu or other Debian-based systems, use the following command:

If you're using CentOS or Red Hat-based systems, use this command:

Step 2: Copying Files with SCP

The scp command is a simple way to securely copy files over SSH. To use scp to transfer a file from your server to the local machine, use this command:

For example, if you want to copy a file named myfile.txt from your server to the /path/to/local/directory on your local machine, use:

Step 3: Copying Files with Rsync

The rsync command is another efficient tool for transferring files, and it has additional features like synchronization and incremental backups. Here's how you can use rsync to copy files to your local machine:

For example, to copy myfile.txt from your server to the /path/to/local/directory on your local machine, use:

Step 4: Verifying the Transfer

Once the file transfer is complete, you can verify it by checking the local directory.

Use the above command to list the contents of the target directory on your local machine and confirm that the file is present.

Conclusion

Whether you choose to use scp or rsync, both tools provide a secure and efficient way to copy files from your remote server to your local machine. The choice between the two depends on your specific needs, with rsync offering additional features like incremental file synchronization.

Now you're ready to securely transfer your files from your server to your local machine using the best tools available!

In this tutorial, we will guide you through the process of creating a new user and giving them sudo privileges on a Linux system.

Step 1: Create a New User

To create a new user, use the useradd command:

Step 2: Set a Password for the New User

Next, set a password for the newly created user:

Step 3: Add the User to the Sudoers Group

To grant the new user sudo privileges, add them to the sudo group:

Step 4: Verify the User's Sudo Access

To check if the user has been added to the sudoers group successfully, use the following command:

Conclusion

You've successfully created a new user and granted them sudo privileges. The new user can now execute commands as a superuser by prefixing commands with sudo.

SSH is one of the most common ways to access and manage servers. Unfortunately, its popularity also makes it a frequent target for hackers. By default, SSH runs on port 22, which is widely known and often scanned by attackers. But what if we told you that changing your SSH port number could dramatically improve the security of your server?

In this article, we’ll show you how to change your SSH port number and hide it from potential attackers, making your server more secure and less vulnerable to brute force and automated attacks.
