Kaisen Linux. Connect And Disconnect WiFi From Commandline In Linux. Ubuntu vs Arch Linux | Average Linux User. Content Ubuntu and Arch Linux are so different that it seems comparing them doesn’t make sense. I was an Ubuntu user for 10 years and last year I switched to Arch Linux. I would like to share my experience with both distros and compare them from an average Linux user perspective. Why Ubuntu vs Arch Linux? There are so many distros to choose from that one can easily get lost. It is also difficult to compare distros without experiencing them for a long time. I also tried many distros but I would always go back to Ubuntu. A year ago, I installed Arch Linux and it was the first time I didn’t go back to Ubuntu. My experience with both Ubuntu and Arch Linux largely reflects their fundamental principles: Ubuntu: release quality, security, usability Arch Linux: simplicity, modernity, freedom Let’s have a look at the details.
Installation Ubuntu This is one of the things I like about Ubuntu. However, the downside of this is I lose control of what I would like to have in my system. Arch Linux Ubuntu. 7 Best Desktop environments for Linux to install in 2021 - Linux Shout.

Intro to Linux Forensics | Count Upon Security. This article is a quick exercise and a small introduction to the world of Linux forensics. Below, I perform a series of steps in order to analyze a disk that was obtained from a compromised system that was running a Red Hat operating system. I start by recognizing the file system, mounting the different partitions, creating a super timeline and a file system timeline. I also take a quick look at the artifacts and then unmount the different partitions. The process of how to obtain the disk will be skipped but here are some old but good notes on how to obtain a disk image from a VMware ESX host.
When obtaining the different disk files from the ESX host, you will need the VMDK files. Following that, you could list the partition table from the disk image and obtain information about where each partition starts (sectors) using the “mmls” utility. This is due to the fact that this partition is of type 0x8e (Logical Volume Manager). Last Modification time. This needs to be looked further. Get Linux System and Hardware Details on the Command Line. While using Linux, there might arise a need to know about the system you are on or the hardware specifications you are using. As a normal Linux user or a software developer, it is important for you to check the compatibility of a software or hardware system that you want to install. Linux command line comes with multiple built-in commands for you to get familiar with the software and hardware platform you are working on. This tutorial provides you with the usage of all these commands.
The commands and examples mentioned in this tutorial have been implemented on Ubuntu 18.04 LTS. Displaying Basic System Information on Linux Shell To know the basic information about your system, you need to be familiar with the command line utility called uname-short for unix name. The uname Command The uname command comes with multiple switches. . $ uname Output: As you can see, the uname command when used without any switches only returns the kernel name i.e., Linux for my system. Get the Linux Kernel Name. Behind the scenes with Linux containers. Can you have Linux containers without Docker? Without OpenShift?
Without Kubernetes? Yes, you can. Years before Docker made containers a household term (if you live in a data center, that is), the LXC project developed the concept of running a kind of virtual operating system, sharing the same kernel, but contained within defined groups of processes. Docker built on LXC, and today there are plenty of platforms that leverage the work of LXC both directly and indirectly. Most of these platforms make creating and maintaining containers sublimely simple, and for large deployments, it makes sense to use such specialized services. Sidestepping the simplicity If you're looking for a quick-start guide to LXC, refer to the excellent Linux Containers website. Installing LXC If it's not already installed, you can install LXC with your package manager. On Fedora or similar, enter: $ sudo dnf install lxc lxc-templates lxc-doc On Debian, Ubuntu, and similar, enter: $ sudo apt install lxc # exit.
30 Best Sources For Linux / *BSD / Unix Documentation On the Web - nixCraft. How to defrag your Linux system. There is a common misconception among GNU/Linux users that our systems never ever need to be defragmented. This stems from the success of the journalized filesystems used by most distributions including EXT2,3 and 4, JFS, ZFS, XFS, ReiserFS and BTRFS. All of these boast smart ways and techniques in regards to the files allocation in the disks, minimizing the fragmentation problem to a point that there is practically no reason to defrag even after many years of installing and uninstalling applications and libraries in the same system.
Fragmentation though can still be an issue though, especially for users that use space limited disks that may not offer many file allocation options. Here's a bulk description of how the (Linux) file allocation procedure works: files are stored in multiple places in the disk, leaving huge unwritten space between them, allowing them to grow unobstructed over time if needed. Now, the first thing that you'll need to do is get a defragment tool installed. The Linux Documentation Project. Shellshock, the Bashdoor Bug - Computerphile. CentOS 7 - The perfect desktop guide.

Want To Learn Linux? These Four Distros Will Take You From Beginner To Pro. If you’re really interested in learning about Linux, there are some distributions that are better than others at helping you out. Depending on how deep you want to go, there are different distros that are ideal for you. Just be sure that you know what level you’re really at.
Packaged Distributions Packaged distros like Ubuntu, , and Fedora, a more advanced and purely open source Linux desktop, are the best distributions to use if you consider yourself to be a beginner or slightly experienced at using Linux. Out of the two, Fedora may be a bit more for slightly experienced users while Ubuntu and Ubuntu-based distributions are for beginners. I recommend these distributions for the starting Linux users because they are the easiest to master. Arch Linux Once you’ve gotten experienced enough, I’d recommend that you move on to Arch Linux. Gentoo While I’m sure a handful of people may disagree with me about this, I believe that Gentoo is the next step after Arch Linux. Linux From Scratch. 14 Command line tips & tricks. In this article you will find a list of 14 practical Linux command-line tips and tricks – in handy Q&A form – that are aimed to provide valuable information for Linux beginners.
I am new to Linux. Experts Q1: advise to never log in as root. How can I find out whether I have logged in as root or not? As you are new to Linux, the first thing that you should know is what root means and why experts say that you should never log in as root (until and unless it is absolutely required). Root is the username for a Linux user account that has read-write-delete access to virtually anything and everything on the system. This user exists by default on every Linux distribution, though some of them (like Ubuntu) require it to be activated manually before first use.
Activating here means configuring the password for root using the ‘passwd’ command. Since the root user account has unlimited privileges, you can do almost anything on a Linux system while logged in as root. Other important points : $ . $ . How To Upgrade Or Switch Linux Distros Without Erasing Your Files. Do you find yourself switching between Linux distributions frequently? When upgrading, do you favor clean installations over in-place upgrades?
Do you hate that you have to back up all your personal data, or else lose it? What if I told you that this doesn’t have to happen? It’s actually quite easy to switch between different Linux distributions or perform clean installations and still retain all of your personal data. How Does It Work? What’s the magic that lets you keep all your personal data? Whenever you install Linux, you have to tell the installer what partition setup you’d like to have on your hard drive. Optionally, you can also have an additional partition called the “swap partition.” However, you have the freedom to create as many partitions as you’d like, and you’re also able to tell the installer which partitions should be used for which folders. Make sure that when you are giving the two partitions space, you give each of them enough room.

Linux system debugging super tutorial. Updated: June 1, 2012 In the last two years, I have introduced you to a number of so-called super-duper system administration tools. We learned how to properly analyze a range of problems by carefully studying symptoms and then isolating and fixing the root cause. We learned about strace and lsof, both immensely powerful tools. We focused on system profiling and auditing. We also worshiped the omnipotent GNU Debugger (gdb). Today, we will use all of these tools, plus the slew of tips and tricks listed in my hacking guides, all three of them, to try to resolve a seemingly impossible problem. The problem we have All right, let's assume that the startup of applications is slow.
