  • How To Install Snap on Linux Mint 20 - idroot

    In this tutorial, we will show you how to install Snap on Linux Mint 20. For those of you who didn’t know, Snap is a package management system for installing and managing applications (called Snaps) developed by Cananoical for Linux operating systems.

I will show you the step-by-step installation of Snap on a Linux Mint 20 (Ulyana).

  • Install Docker and Portainer - blackMORE Ops

    Docker is a set of platform as a service (PaaS) products that use OS-level virtualization to deliver software in packages called containers. Containers are isolated from one another and bundle their own software, libraries and configuration files; they can communicate with each other through well-defined channels. Because all of the containers share the services of a single operating system kernel, they use fewer resources than virtual machines. The service has both free and premium tiers. The software that hosts the containers is called Docker Engine.

    Portainer CE is a lightweight ‘universal’ management GUI that can be used to easily manage Docker, Swarm, Kubernetes and ACI environments. It is designed to be as simple to deploy as it is to use. Portainer consists of a single container that can run on any cluster. It can be deployed as a Linux container or a Windows native container. Portainer allows you to manage all your orchestrator resources (containers, images, volumes, networks and more) through a super-simple graphical interface. A fully supported version of Portainer is available for business use.

  • Learn Usage of chown (Change Ownership) Command in Linux

    Under Linux, the ownership of created or existing files and directories is associated with a specific Linux system user, group, or other (file/directory permission access types).

    However, files or directories ownership verdicts are not final as it is possible to chown (Change Ownership) of any file and/or directory within the Linux operating system.

  • Learn Usage of chgrp (Change Group) Command in Linux

    If you are reading this article on the chgrp command, there is a high chance you have explored all the depths of Linux’s chown command and chmod command.

  • How to Install PostgreSQL 14 in Ubuntu 20.04

    There are specific database software attributes that make PostgreSQL stand out against other database platforms. The first and obvious attribute is its open-source nature. This PostgreSQL trait puts it on continuous developmental milestones. Both its community and developers seek to evolve PostgreSQL into an enterprise-class performing software. Existing PostgreSQL community platforms help users deal with emerging bugs, and also understand its various functionalities and use cases. Other PostgreSQL strengths are in its unique functions like Store Procedure, Diverse Indexing Techniques, Flexible Full-text search, Diversified Extension Functions, and Diverse kind of Replication.

  • How to upload an ISO image to the Proxmox Server - Unixcop the Unix / Linux the admins deams

    Hello, friends. We have already shown you how to install Proxmox and we noticed that the process is easier than you might think. Now I will show you how to upload an ISO image to the Proxmox server. To do this, I will use the graphical method or through the terminal. With Proxmox we will be able to virtualize systems professionally and to do many things more like cluster, backups, and others. However, to start with the virtualization we have to have an ISO image of the system. So, with a server that is far away from our location, how to do it? How to have the ISO image on the server so that Proxmox can manage it? Well, that’s what I will show you today. Let’s go for it.

  • How to install FreeOffice 2021 on Ubuntu 20.04 Linux - Linux Shout

    One of the best free alternatives to Microsoft Office is FreeOffice, developed by a German software company- SoftMaker. Recently, they have upgraded their Office suite to version 21.

It offers a Microsoft office ribbon-like interface and three modules- TextMaker 21 to create documents; PlanMaker 21 to create sheets (Excel alternative) and Presentations 21 for making slides like MS-Powerpoint.

  • How to verify checksum on Linux | FOSS Linux

    A checksum is small-sized data obtained from a block of digital data used to detect errors. The checksum value uses a transmission message to represent bit numbers. Extensively, it has been used and still is in use by IT experts to detect high-level errors that might happen during data transmission. Before transmission, every bit of data is assigned a checksum value after running a cryptographic hash function. Checksum sometimes is termed as a hash sum or hash value. It is a long data string that contains various numbers and letters. They work by providing the receiving end information about the data transmission to deliver the full range of data. Checksum acts as a fingerprint for files since it contains a long string of numbers and letters. It aids in obtaining the number of bits included in a transmission. Suppose the checksum value calculated by the end-user is slightly different from the original checksum value of the file. In that case, it alerts all parties involved in the transmission that a third party corrupted the file. The receiver can then investigate what went wrong or try re-downloading the file. Standard protocols used to determine checksum numbers are the transmission control protocol (TCP) and the user diagram protocol (UDP). TCP is more reliable for tracking transmitted packets of data, but UDP may be beneficial to avoid slowing down transmission time.

  • How to create and extract cpio archives on Linux Examples

    Although the cpio archiving utility is nowadays used less than other archiving tools like tar, it is still good to know how it works, since it is still used, for example, to create initramfs images on Linux and for rpm packages, which are used mainly in the Red Hat family of distributions. In this tutorial we see how to create and extract cpio archives using the GNU cpio utility, and how to obtain a list of the files they contain.

  • How to hash passwords on Linux

    Passwords should never be stored as plain text. Whether we are talking about a web application or an operating system, they should always be in hash form (on Linux, for example, hashed passwords are stored in the /etc/shadow file). Hashing is the process through which, by the use of some complex algorithms, a password is turned into a different string. Such process is one-way: there is no way to revert an hashed password to its original, plain text form. Hashing often involves the use of random data as additional input for the hash algorithm, so that the same password, hashed two times, doesn’t produce the same result. This random data is called salt. In this tutorial we explore some methods we can use to hash passwords on Linux.

  • A Decade with Jekyll

    Today I’d like to look back on my experience with Jekyll, the static site generator (SSG) that I’m using to publish this site and my other blogs Meta Redux and Emacs Redux. Back in the day Jekyll was a trend-setter - it basically defined the SSG category and every subsequent tool in it was compared to Jekyll. A lot has happened since 2011: [...]

  • ZFS Storage pool layout: VDEVs

    The storage pool of ZFS constitutes one or more virtual devices that are, in general, called vdevs. A Vdev is either a single disk, or two or more disks which mirrors each other, or a group of disks that organizes together. The RAID layout sets on each vdev as opposed to the storage pool. Similarly, data that is present in the storage pool strips across all vdevs which also means that the loss of one vdev would result in pool failure.

  • [Old] The Basic Guide to Working with ZFS

    RAID-Z1 replaces RAID5 in a traditional setup. Performance is pretty equivalent, but the benefit is in some of the features. As mentioned before, you get healing or at least detection of bit rot or a bad sector, it’s a lot easier to set up with mixed drives, etc. RAID-Z2 (equivalent to RAID6) performs better from my experience than any traditional RAID6 setup I’ve used with equivalent drives on an equivalent machine.
