The core component of each Linux operating system is the Linux kernel. It manages the system’s resources, and acts as an intermediary between the computer’s hardware and software. The Linux kernel is a software that has a modular design. A kernel module, or often referred to as a driver, is a piece of code that
How to Set Up Automatic Kernel Updates on Linux
It’s simple process to apply security updates to the Linux kernel using apt, yum, or kexec tools. But when managing multiple servers with different Linux distribution then it can be time-consuming and tedious. This article show you how to set up automatic kernel updates without reboot using the live patching. If you do manual update
Dmesg Command in Linux
The dmesg command-line utility is used to view and control the kernel ring buffer in Linux and other Unix-like operating systems. It is useful for examining kernel boot messages and debugging hardware related issues. In this guide, we will show you the basics of the dmesg command. In the Linux operating system the Linux kernel
How to Setup Automatic Kernel Updates on Linux
Applying security updates to the Linux kernel is a straightforward process that can be done using tools such as apt , yum, or kexec. However, when managing hundreds or thousands of servers running different Linux distribution to patch, this method can be challenging and time-consuming. Manually updating the kernel requires rebooting the system. This results
Sysctl Command in Linux
As a Linux system administrator, sometimes you may need to modify the default kernel’s behavior. For example, you may need to enable the magic SysRq key or to increase the number of connections that Kernel will accept. The kernel parameters can be set when building the kernel, on system boot, or at runtime. This article
Modprobe Command in Linux
The Linux kernel is the core component of the Linux operating system. It manages the system’s resources, and it is a bridge between your computer’s hardware and software. The Linux kernel has a modular design. A kernel module, or often referred to as a driver, is a piece of code that extend the kernel’s functionality.
Lsmod Command in Linux (List Kernel Modules)
lsmod command is used to display the information of loaded modules in the Linux kernel. Linux kernel modules are system-level software that can be used directly by operating system kernel.
