  • I need to remember to check for ZFS filesystems being mounted

    We have a variety of management scripts on our fileservers that do things on 'all ZFS filesystems on this fileserver' or 'a specific ZFS filesystem if it's hosted on this fileserver'. Generally they get their list of ZFS filesystems and their locations by looking at the mountpoint property (we set an explicit mount location for all of our ZFS filesystems, instead of using the default locations). Most of the time this works fine, but every so often one of the scripts has blown up and we've quietly fixed it to do better.

  • Three DDoS attacks on my personal website

    Update: After posting the video yesterday, the site was hit by more low-complexity DDoS attacks, mostly just spamming one URL at a time. After I cleaned those up, the attacker finally switched to a more intelligent offense, posting actual comments to the site overnight. This morning I noticed that, and the fact the attacker found I left my edit domain un-proxied, so I switched to a different IP on DigitalOcean and shored up the Cloudflare configuration a bit more.

    It was a good thing I did that, because about the same time, I got an email from DigitalOcean support saying they had to blackhole the other IP for getting 2,279,743 packets/sec of inbound traffic. Sheesh.

    After cleaning up a few bits of fallout, the site should be running a bit better at this point, DDoS or no.

  • How to install go1.19beta on Ubuntu 22.04 – NextGenTips

    In this tutorial, we are going to explore how to install go on Ubuntu 22.04 Golang is an open-source programming language that is easy to learn and use. It is built-in concurrency and has a robust standard library. It is reliable, builds fast, and efficient software that scales fast. Its concurrency mechanisms make it easy to write programs that get the most out of multicore and networked machines, while its novel-type systems enable flexible and modular program constructions. Go compiles quickly to machine code and has the convenience of garbage collection and the power of run-time reflection. In this guide, we are going to learn how to install golang 1.19beta on Ubuntu 22.04. Go 1.19beta1 is not yet released. There is so much work in progress with all the documentation.

  • 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.
