Secure Copy Protocol (SCP) is a command-line tool that allows you to securely copy files and directories between your local machine and a remote server over SSH. Here’s how you can use SCP to copy files in both directions: from your local machine to a remote server and from a remote server to your local machine.

Copying from Local to Remote (Upload)

To copy a file from your local machine to a remote server, use the following command:

If you want to see detailed boot messages instead of the splash screen when your Ubuntu system starts up, you can enable verbose mode by following these steps:

1. Open a terminal window.

2. Edit the Grub configuration file by running the following command:

   1	sudo nano /etc/default/grub

   This will open the Grub configuration file in the Nano text editor.

If you’re encountering a virtual network failure during a verbose boot, where you see detailed messages about the networking initialization process, you may need to take specific actions to resolve the issue. One possible solution is to remove or rename the /etc/init/networking.conf file. Here’s a step-by-step guide on how to do this:

Note: Before proceeding, make sure you have administrative privileges on your system.

Step 1: Access the Command Line

You’ll need to access the command line interface of your system to perform these actions. You can usually do this by opening a terminal or console window. If you’re already logged in, proceed to the next step.

You can enhance your system’s security by setting up an automated email notification whenever someone logs in via SSH. This can help you stay informed about unauthorized access to your system. Below is a guide on how to implement this feature.
