  • Static and dynamic IP address configurations: DHCP deployment

    In my Static and dynamic IP address configurations for DHCP article, I discussed the pros and cons of static versus dynamic IP address allocation. Typically, sysadmins will manually configure servers and network devices (routers, switches, firewalls, etc.) with static IP address configurations. These addresses don’t change (unless the administrator changes them), which is important for making services easy to find on the network.

    With dynamic IP configurations, client devices lease an IP configuration from a Dynamic Host Configuration Protocol (DHCP) server. This server is configured with a pool of available IPs and other settings. Clients contact the server and temporarily borrow an IP address configuration.

  • How to deploy Samba on Linux as an Active Directory Domain Controller - TechRepublic

    Active Directory (AD) is Microsoft's way of making it possible to create and apply policies to machines associated with a network. It's a tool widely used by businesses and network administrators everywhere.

    Microsoft's solution is not the only means to make this happen; the open source Samba makes it possible to deploy an Active Directory Domain Controller. With this controller, you can then create users, and even set policies.

    I will be writing a series of tutorials on this subject. In this first piece, we'll be deploying the Samba AD on an instance of Ubuntu Server 20.04.

  • 1 click install uTorrent on Ubuntu 21.04 [ with terminal ]

    With over 150 million users uTorrent is the most widely used BitTorrent client outside China; globally only behind Xunlei. The “μ” (Greek letter “mu”) in its name comes from the SI prefix “micro-“, referring to the program’s small memory footprint: the program was designed to use minimal computer resources while offering functionality comparable to larger BitTorrent clients such as Vuze or BitComet.

    uTorrent was controversial for mining cryptocurrency when installed. They had removed the cryptocurrency miner in later versions but it had already done irreversible damage to uTorrent’s reputation.

  • 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.
