  • How to Find the IP Address in Linux

    An IP address is a unique address that identifies a device on the internet or a local private network. Every computer in the network requires its own unique IP address to get identified. There are two different IP addresses: private and public. A computer can be assigned private IPs or public IP or both.

    A public IP is an address that is exposed to the internet. Devices that are assigned public IP can be accessed from the internet. Whereas private IP is accessible to a local internal network.

    In this tutorial, we learn the different ways to find the IP Address of a Linux system.

  • How To Enable Hibernation On Ubuntu (When Using A Swap File) - Linux Uprising Blog

    This article explains how to enable hibernation using systemd on Ubuntu when using a swap file (which is default for Ubuntu at least since version 18.04).

    My laptop's battery drains quite fast while it's sleeping. I've tried some solutions / workarounds, like this one (except for me the problem wasn't that the laptop was losing half its energy overnight, but all of it in only a few hours), but to no avail. So I decided to enable the hibernate option (suspend to disk) and use that instead of the default sleep option (suspend to RAM), because it uses less power, so the laptop battery is not drained while not in use, albeit taking a bit longer to wake up from hibernation than from sleep. So here's how to do that.

    The instructions below may work on other Linux distributions, but I only tested this on Ubuntu (it should work in the exact same way on any Debian-based and Ubuntu-based Linux distributions, including Pop!_OS, etc.). On non Debian-based Linux distributions you may need to use different commands for updating GRUB 2 (step 4) and regenerating initramfs (step 6) as these are Debian-specific commands.

  • 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.
