  • Dos2unix Linux Command

    “Are you looking for a way to convert DOS or Mac format to Unix format? Any time you need to share files between Windows and Unix systems, the file format, especially plain-text, comes into play. The main difference is in the line break. For Unix and Linux systems, an end of a line gets represented by a single character, the Line Feed (LF).

    In contrast, Windows files use two characters to signify a line break, the carriage return (CR), represented as (\r), and the Line Feed (LF), expressed as (\n).

    Unless you have the right way of converting the files, you will have a broken script, code, or formatting, which is annoying. Here’s the good part, this guide will present examples of the dos2unix command usage to get you started. Check it out!”

  • Kinit Linux Command

    The Kinit in Linux is a command often used for renewing or caching/renewing a Kerberos ticket authentication and granting features. This tool is used for the same purpose that MIT and SEAM References use Kinit in other Kerberos implementations. Notably, you can only use the Kinit command once you register as a principal with the KDC or Key Distribution Center.

    Ideally, the KDC alternatives, often identified by {realms} and {kdcdefault} features contained in the kdc.conf (which is the KBR5 configuration file), come in handy if you do not indicate any ticket flags in the command line.

    This article describes what a Kinix Linux command is. It also provides a step-by-step guide on using the Kinit tool to renew, obtain, or cache your ticket-granting tickets. Finally, we will highlight Kinit syntax or flags, environment variables, and files.

  • How to Monitor Linux File Access Using Auditd

    Successfully monitoring Linux file access is a very important milestone for users or Linux administrators confined in a shared or public network setting. Linux file access monitoring helps us answer questions like Who has had access to this file within the last week? Can I get a username list of all users accessing file x? Can I know when file y is being accessed?

    The set logging policies on your Linux operating system distribution should give us timely statistics regarding the system user and the period in which queried file(s) were accessed.

    Auditd or Audit Daemon emulates a Linux Auditing System solely focused on the userspace component. Under the Linux operating system spectrum, anything that is labeled a daemon implies that it is a background running service/application. Therefore, Auditd comfortably runs as a background service while collecting and writing audit-associated log files.

  • How To Install MongoDB on AlmaLinux 9 - idroot

    In this tutorial, we will show you how to install MongoDB on AlmaLinux 9. For those of you who didn’t know, MongoDB is a high-performance, highly scalable document-oriented NoSQL database. Unlike in SQL databases where data is stored in rows and columns inside tables, in MongoDB, data is structured in JSON-like format inside records which are referred to as documents. The open-source attribute of MongoDB as a database software makes it an ideal candidate for almost any database-related project. This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you the step-by-step installation of the MongoDB NoSQL database on AlmaLinux 9. You can follow the same instructions for CentOS and Rocky Linux.

  • Self-host a Ghost Blog With Traefik

    Ghost is a very popular open-source content management system. Started as an alternative to WordPress and it went on to become an alternative to Substack by focusing on membership and newsletter. The creators of Ghost offer managed Pro hosting but it may not fit everyone's budget. Alternatively, you can self-host it on your own cloud servers. On Linux handbook, we already have a guide on deploying Ghost with Docker in a reverse proxy setup. Instead of Ngnix reverse proxy, you can also use another software called Traefik with Docker. It is a popular open-source cloud-native application proxy, API Gateway, Edge-router, and more. I use Traefik to secure my websites using an SSL certificate obtained from Let's Encrypt. Once deployed, Traefik can automatically manage your certificates and their renewals. In this tutorial, I'll share the necessary steps for deploying a Ghost blog with Docker and Traefik.
