  • My ISP Is Killing My Idle SSH Sessions. Yours Might Be Too.

    We found the culprit! The connection tested after waiting slightly more than 60 minutes didn’t work, meaning they dropped the connection from their NAT table. 1 hour is too short time for them to wait – they should wait at least 2 hours and 4 minutes. I documented my findings, and sent an email to my ISP. I quickly got a response back acknowledging that this is a bug on their side, and thanking me for my research. They still haven’t fixed the problem though.

    The tcp-keepalive-test gave the same result, but strangely enough the tcp-recv-test reported all connections as working. I assume this is because I pay my ISP to have a static public IPv4 mapped to my CGN address. But then why did the server’s keepalive packages get dropped in the SSH example? I speculate that my ISP drops those because they don’t refer to a valid TCP session anymore.

    Actually they shouldn’t track my connections at all – they should just forward all packages, and only translate the source or destination IP. But that’s a problem for another day.

  • 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.
