Welcome to the first part of my syslog-ng tutorial series. In this part, I give you a quick introduction what to expect from this series and try to define what syslog-ng is. I plan to release parts of my tutorial around every week. Of course, the Christmas holidays and the upcoming conference season may cause some delays. Each part will be released as a blog accompanied by a video. It is up to you, which version you follow.

The November syslog_ng newsletter is now on-line: Testing syslog-ng 4.0 syslog-ng Store Box federated single sign-on support via OpenID Connect (OIDC) Nightly syslog-ng container images Type support: working with sudo logs in syslog-ng 4.0 It is available at https://www.syslog-ng.com/community/b/blog/posts/the-syslog-ng-insider-2022-11-4-0-oidc-nightly-sudo syslog-ng logo

Each new MacOS release brings some surprises when it comes to compiling syslog-ng. MacOS Ventura has been released recently, while Homebrew has also been updated. So here are some updated instructions for MacOS Ventura (and also for the last MacOS minor release before Ventura). https://www.syslog-ng.com/community/b/blog/posts/syslog-ng-on-macos-ventura syslog-ng logo

One of the recurring questions at conferences was whether there is a way to check cached sudo credentials without updating them. Version 1.9.12 of sudo introduces the -N option which makes this possible, and also allows running any commands without updating the cached credentials. You can learn more about the new -N option in my latest sudo blog at https://www.sudo.ws/posts/2022/10/running-sudo-without-updating-cached-credentials/ Sudo logo

How to get started with syslog-ng? There are two main resources: the syslog-ng documentation and the syslog-ng blogs. You should learn the concepts and basics from the documentation. The blogs document use cases and you can use the docs as a reference. syslog-ng logo Read the rest of my blog at: https://www.syslog-ng.com/community/b/blog/posts/syslog-ng-101-how-to-get-started-with-learning-syslog-ng

Sudo is one of the most used command line tools in the Linux / UNIX / macOS world. It gives users the ability to execute commands as another user. Most often it is used to gain root (administrator) privileges. Sudo was created when there were a small number of independent large systems. Some support for multiple hosts, central management and monitoring were later added to it. These tools do their jobs, however large enterprises require ease of use, reporting and monitoring.

The syslog-ng team started publishing container images many years ago. For quite a while, it was a manual process, however, a few releases ago, publishing a container image became part of the release process. Recently, nightly container images have also become available, so you can test the latest features and bug fixes easily. The syslog-ng images are still available under the Balabit namespace on the Docker hub. Balabit was bought by One Identity almost five years ago, and we stopped using the old company name years ago.

The September syslog-ng newsletter is now on-line: 3.38.1 released, 4.0 almost feature complete syslog-ng Store Box SQL source Why is my syslog-ng disk-buffer file so huge even when it is empty?

The 31st birthday of the Linux #kernel was yesterday. For this occasion some opensource.com contributors (including me) shared how we got started with Linux. Lots of nice memories :-) The article is available at https://opensource.com/article/22/8/linux-birthday-origin-stories flower

Whether attending conferences or reading blogs, I often hear several misconceptions about sudo. Most of these misconceptions focus on security, flexibility, and central management. In this article, I will debunk some of these myths. Many misconceptions likely arise because users know only the basic functionality of sudo. The sudoers file, by default, has only two rules: The root user, and members of the administrative wheel group, can do practically anything using sudo.
