  • Monitoring with Prometheus 2.0

    Prometheus is a monitoring tool built from scratch by SoundCloud in 2012. It works by pulling metrics from monitored services and storing them in a time series database (TSDB). It has a powerful query language to inspect that database, create alerts, and plot basic graphs. Those graphs can then be used to detect anomalies or trends for (possibly automated) resource provisioning. Prometheus also has extensive service discovery features and supports high availability configurations. That's what the brochure says, anyway; let's see how it works in the hands of an old grumpy system administrator. I'll be drawing comparisons with Munin and Nagios frequently because those are the tools I have used for over a decade in monitoring Unix clusters.

  • A survey of some free fuzzing tools

    Many techniques in software security are complicated and require a deep understanding of the internal workings of the computer and the software under test. Some techniques, though, are conceptually simple and do not rely on knowledge of the underlying software. Fuzzing is a useful example: running a program with a wide variety of junk input and seeing if it does anything abnormal or interesting, like crashing. Though it might seem unsophisticated, fuzzing is extremely helpful in finding the parsing and input processing problems that are often the beginning of a security vulnerability.

    Many common types of security vulnerabilities occur when something goes wrong while processing input — for example, the classic buffer overflow. These are interesting in that they tend to manifest first as instability: when input too long for the buffer is read, the program will probably misbehave and simply crash. With careful design of the too-long input, it might be possible to turn this crash into arbitrary code execution. The goal of fuzzing is to find any situations where a program crashes due to unusual input. While fixing these bugs makes the software more stable, it also closes the door on any security issues that could result from them.

Samsung, Red Hat to Work on Linux Drivers for Future Tech

The metaverse is expected to uproot system design as we know it, and Samsung is one of many hardware vendors re-imagining data center infrastructure in preparation for a parallel 3D world. Samsung is working on new memory technologies that provide faster bandwidth inside hardware for data to travel between CPUs, storage and other computing resources. The company also announced it was partnering with Red Hat to ensure these technologies have Linux compatibility. Read more

  • 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.
