In today's tech world, Docker is a total game-changer! It's an open-source platform that's turning app development, deployment, and management upside down. With containerization magic, Docker makes apps run smoothly across any platform. No more compatibility nightmares! Dev and ops teams are having better communication now, thanks to Docker's seamless collaboration. And it's not just that – faster development, easy scaling, and integration, you name it!

Logical Volume Management (LVM) is a popular method of managing storage on Linux operating systems. It allows administrators to create and manage logical volumes, which can span multiple physical disks and can be resized on-the-fly. In this blog post, we will walk through the process of configuring LVM on Linux.

Disk space management is always a frustrating job. The situation would become even more challenging when one of your partitions on a disk runs out of space. Here the LVM comes to the rescue.

Logical Volume Manager (LVM) is used to manage storage devices, by utilizing the kernel’s device mapper feature to provide an additional layer of abstraction on the underlying physical disk layout. This makes the disk space management very flexible and provides many features, like the ability to add space to a logical volume even when the filesystems are mounted and active.

SSHD service is used to secure communications between two untrusted hosts over an insecure network or internet.

In this post we are going to setup a new sshd service from scratch and we learn how to harden this service.

The first step to practice learning Linux or even building your own lab is to install Linux on a virtual machine.

Here we are going through every step, so we can have a new freshly installed Debian Linux on our machine.
