  • A Guide to Network Traffic Analysis Utility: TCPDUMP – Linux Hint

    Tcpdump is a network packet sniffing command-line utility. It is most commonly used for troubleshooting networks and testing security issues. Despite the absence of a graphical user interface, it’s the most popular, powerful, and versatile command-line utility.

    It is native to Linux such that most of the Linux distributions install it as a part of the standard OS. Tcpdump is a libpcap interfaced program, which is a library for network datagram capture.

  • How to upgrade Gentoo kernel – Linux Hint

    Gentoo is a rolling release, meaning that you have new updates available at regular intervals, but there are no major updates. The idea behind this is never to have incompatible parts of the system because they belong to different major releases. You upgrade as you need to. In many other distributions, the new kernels come with the new release. In Gentoo, you have new kernels when it has been tested. You can, of course, take the latest kernel out there and run that. With the caveat that you may be quite lonely on the forums if you have problems.

  • Writing a Résumé in LaTeX - Michael Lustfield

    Way back in my college days, I was trying to write the first version of my résumé. As a pedantic IT guy, I wanted to get everything perfect so that I could stand out despite having very little practical experience.
    Trying to write my résumé in OpenOffice--yes, I'm that old--proved to be quite difficult. Attempting to select text sometimes resulted in selecting the background which made it impossible to select text; trying to highlight text would sometimes result it that text disappearing; moving one little object could sometimes destroy formatting and alignment of everything else; maintaining consistent text formatting was challenging; so many other issues...

  • Ways to Determine the File System Type in Linux – Linux Hint

    In computing, a filesystem is a layout or format used to store files in a storage device. A filesystem is used to logically divide a storage device to keep different files organized nicely in the storage device to be searched, accessed, modified, removed, etc. easily from the storage device.
    There are many filesystems available today. Different filesystems have different structures, logics, features, flexibility, security, etc. Some of the most common filesystems are Ext4, Btrfs, XFS, ZFS, NTFS, FAT32, etc.

    There are times when a Linux system administrator will need to determine the filesystem type to simply mount the filesystem or to diagnose problems with the filesystem. Different filesystems have different tools for diagnosing problems, checking for errors and fixing them, etc. So, you have to know the filesystem a storage device is using to determine the maintenance tool/tools to use.

    In this article, I will show you different ways you can determine the filesystem type in Linux. So, let’s get started.

  • 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.
