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 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.

Version 4.0 of syslog-ng is right around the corner. It hasn’tyet been released; however, you can already try some of its features. The largest and most interesting change is type support. Right now, name-value pairs within syslog-ng are represented as text, even if the PatternDB or JSON parsers could see the actual type of the incoming data. This does not change, but starting with 4.0, syslog-ng will keep the type information, and use it correctly on the destination side.

The July syslog-ng newsletter is now on-line: RHEL 9 syslog-ng news How does the syslog-ng disk-buffer work? Installing syslog-ng on Microsoft Linux It is available at https://www.syslog-ng.com/community/b/blog/posts/the-syslog-ng-insider-2022-06-rhel-9-disk-buffer-microsoft-linux syslog-ng logo

A three parts blog series: The syslog-ng disk buffer is one of the most often used syslog-ng options to ensure message delivery. However, it is not always necessary and using the safest variant has serious performance impacts. If you utilize disk-buffer in your syslog-ng configuration, it is worth to make sure that you use a recent syslog-ng version. From this blog, you can learn when to use the disk-buffer option, the main differences between reliable and non-reliable disk-buffer, and why is it worth to use the latest syslog-ng version.

Yes, Microsoft has its own Linux distribution, called CBL-Mariner. It is an internal Linux distribution by Microsoft used for cloud infrastructure and edge products and services. And even if it is not installed in the OS by default, CBL-Mariner also includes syslog-ng. Read the rest of my blog at https://www.syslog-ng.com/community/b/blog/posts/installing-syslog-ng-on-microsoft-linux to learn how to install syslog-ng on it and what features are available. syslog-ng logo

Red Hat Enterprise Linux 9 became generally available recently. Version 3.35 of syslog-ng has been part of EPEL 9 (the semi-official extra software repo for RHEL maintained by Fedora packagers) for a while and now I enabled a few more destination drivers. I also enabled RHEL 9 support in my unofficial Git snapshot packages, so I can support RHEL 9 together with other RHEL and Fedora versions on the next syslog-ng release.
