    Laptop battery charging and discharging status can be identified using the following two commands.

  • 5 advanced rsync tips for Linux sysadmins | Enable Sysadmin

    In a previous article entitled Sysadmin tools: Using rsync to manage backup, restore, and file synchronization, I discussed cp and sftp, and looked at the basics of rsync for moving files around. There are also a couple of other great articles here on Enable Sysadmin on tar and SSH you should take a look at. Copying files to and from remote systems and having an easy way to run a backup of something you're working on (or, for that matter, critical company data) are basic, useful tools in the sysadmin toolbox that I use again and again. Sometimes, however, you may want to do something a little more sophisticated, like move data across a less trusted or slower link. Rsync can provide encryption to protect it in transit, compression to make it flow better, and checksums to ensure you get what you were expecting.

  • How to install Virtualmin on Ubuntu 20.04 for a cPanel/CentOS-like web hosting control panel - TechRepublic

    For many, Red Hat pulling support from the standard CentOS releases had some serious side effects. One of the biggest dominoes to fall was cPanel--for many web hosting companies, cPanel is the de facto standard control panel. It offers absolutely everything necessary to manage the hosting of your every client's needs.

    Once Red Hat pulled the plug on CentOS 8, cPanel announced they wouldn't be supporting CentOS Stream. The good news is that the company is accelerating their efforts to support Ubuntu Server LTS, and should have that ready to ship by late 2021.

    For those looking to either migrate away from CentOS or are looking for something that can be used on the Ubuntu platform for now (or for good), there's always Virtualmin.

  • 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.
