  • Struggling With the Linux Secure Copy Command? Use This scp Example

    The scp command lets you copy a file efficiently between two different hosts. The syntax for scp reuses the syntax of cp, so it should feel familiar to most Linux users.

    The tricky bit with the scp command is that either source or destination may be remote i.e. a computer connected to another network, different from your local one. When specifying a file for copying, you’ll need to include details about the remote host as well. This includes its IP address and username.

  • Junichi Uekawa: Surrounding a region with Emacs lisp.

    Surrounding a region with Emacs lisp. I wanted to surround a region with HTML tags and here's what I learnt today. Specifying "r" in interactive gives two numbers, begin and end. When I want to obtain multiple kinds of values in interactive, I can use newlines to delimit. set-marker is an api to keep a marker at relative position even after edits, API needs making make-marker to create an empty marker first, and seems like the number of markers affects editing speed so the API is made to allow reuse of markers. After I got these going I could now write.

    Setting wake-on-lan in Debian way. There's several ways that your network interfaces can be configured. The Debian way is to use ifup/ifdown. Make sure your network is configured with it by checking ifquery. nmcli d and networkctl list are NM and systemd equivalents of commands. After you know which one is managing your device you can go ahead and set up WoL configuration appropriately. Default Debian installation would probably start with a ifup/ifdown config.

  • 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.
