There may be a time when you need to disable some kernel modules from being loaded during your Linux system’s boot time. In this guide, we will discuss a few different ways to blacklist a module, including its dependencies, on Ubuntu and any other Debian based distros. This will effectively permanently disable a module from loading during the boot time.
In this tutorial you will learn:
Sharing files between computers and servers is an essential networking task. Thankfully, NFS (Network File System) is available for Linux systems and makes the job extremely easy. With NFS properly configured, moving files between computers is as easy as moving files around on the same machine. Since NFS functionality is built directly into the Linux kernel, it is both powerful and available on every Linux distro, although the configuration can differ slightly between them.
In this guide, we’ll show how to install and configure NFS on major Linux distros, like Ubuntu and others based on Debian, and Fedora and others based on Red Hat. The configuration will involve a server (which hosts the files) and one client machine (which connects to the server to view or upload files). Follow along with the steps below to get NFS setup on your own system.
In this tutorial you will learn:
Knowing the architecture of your system’s processor is essential when picking an operating system to download and install. Certain editions of Linux and other operating systems are typically only made to work with a certain architecture, whether that be x86 (32 bit), x86-64 (64 bit), ARM (in the case of Raspberry Pi systems), etc. Furthermore, software that you are interested in running may only be designed to work with a particular architecture.
Every time a Linux system is booted, there are a number of kernel modules that will be loaded by the system and used to provide additional support for filesystems, new hardware, and many other things. Obtaining information about particular kernel modules may a be an important troubleshooting skill. In this tutorial, we will explain how to obtain module information such as description, dependency, author or relevant object file name using the modinfo command and its various options.
Puppet is a powerful tool to automate server configuration, deploy updates or other configuration, and manage multiple systems at once. Puppet also has its own programming language, which is easy to understand even for inexperienced programmrs. The application is free, open source, and can be installed on Ubuntu Linux.
Nearly every Linux distribution these days uses the sudo utility as a way to grant non-privileged users the ability to execute commands as privileged root users. You may have noticed that after entering your sudo password once, you can continue to execute commands without needing to re-enter it for five minutes. We can even extend this convenience by allowing any sudo commands to be executed without a password.
The ext4 filesystem includes multiple improvements in terms of performance, over its predecessor ext3. Ext4 is not only faster than ext3, but can also handle much larger filesystems and files, and lots of other improvements under the hood. If you haven’t yet upgraded to ext4 on Linux, it’s definitely time to do so.
The purpose of this tutorial is to describe some simple hard drive speed tests that you can perform using your Linux system and the command line tool hdparm.
Let’s start by explaining what write-back caching is and how it works to better understand the Linux write cache. Write caching is a feature available on most hard drives that allows them to collect all data into the drive’s cache memory, before being permanently written to disk. Once a certain amount of data is collected in the hard drive’s cache memory, the whole data chunk is transferred and stored with a single writing event.
The purpose of this guide is to learn about enable or disable Linux HDD sleep. cover the steps necessary to change a hard drive’s sleep/standby mode timer on Linux. You can either enable standby mode on a storage device, disable standy completely, or adjust the current time it takes for a hard drive to enter standby.
