  • What Is SSH and What Does It Stand For?

    OpenSSH is a widely-used open-source implementation of SSH. The original free version of SSH was developed by Tatu Ylönen. Later versions of Ylönen's work were proprietary, meaning they cost money to license and use, and you couldn't make unauthorized changes to the protocol.

    Thus, a team of developers forked the original free version of SSH and named it OpenSSH, which is now developed as part of OpenBSD (an open-source operating system). All major operating systems, such as Windows, macOS, and the numerous Linux distributions, support OpenSSH.

  • OpenSSL, LibreSSL, LibreTLS and all the terminological irony – Michał Górny

    While we’re discussing the fate of LibreSSL, it’s worth noting how confusing the names of these packages became. I’d like to take this opportunity to provide a short note on what’s what.

    First of all, SSL and its successor TLS are protocols used to implement network connection security. For historical reasons, many libraries carry ‘SSL’ in their name (OpenSSL, LibreSSL, PolarSSL) but nowadays they all support TLS.

  • Reproducible Builds (diffoscope): diffoscope 164 released

    The diffoscope maintainers are pleased to announce the release of diffoscope version 164. This version includes the following changes:

    [ Chris Lamb ]
    * Truncate jsondiff differences at 512 bytes lest they consume the entire page.
    * Wrap our external call to cmp(1) with a profile (to match the internal
      profiling).
    * Add a note regarding the specific ordering of the new
      all_tools_are_listed test.
    
    [ Dimitrios Apostolou ]
    * Performance improvements:
      - Improve speed of has_same_content by spawning cmp(1) less frequently.
      - Log whenever the external cmp(1) command is spawn.ed
      - Avoid invoking external diff for identical, short outputs.
    * Rework handling of temporary files:
      - Clean up temporary directories as we go along, instead of at the end.
      - Delete FIFO files when the FIFO feeder's context manager exits.
    
    [ Mattia Rizzolo ]
    * Fix a number of potential crashes in --list-debian-substvars, including
      explicitly listing lipo and otool as external tools.
     - Remove redundant code and let object destructors clean up after themselves.
    
    [ Conrad Ratschan ]
    * Add a comparator for Flattened Image Trees (FIT) files, a boot image format
      used by U-Boot.

  • 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.
