Red Hat Shoots Itself in the Foot Again

Просмотров 1,3 тыс.Год назад

Red Hat shoots itself in the foot again by announcing that they would no longer allow the general public to download the source code for Red Hat Enterprise Linux. This will cause problems for the RHEL clone publishers, such as AlmaLinux and Rocky Linux. It has also caused a huge backlash from Linux users, and at least some have already decided to switch from the RHEL ecosystem to community-base...

Demystifying Ubuntu's Uncomplicated Firewall

Просмотров 750Год назад

Ubuntu's Uncomplicated Firewall, or ufw, is a handy front-end for either iptables or nftables. As the name suggests, ufw vastly simplifies the process of setting up a basic Linux firewall. You can also set up more complex firewall configurations, but Ubuntu doesn't do a good job of showing you how to do that. Note that ufw is also available on Debian and Debian-based Linux distros as well as on...

With a redundant disk setup, your server can keep going without data loss or downtime if a drive fails. You can use RAID with Linux, Windows, or macOS. NOTE: I slightly misspoke at the end of the video when I said that you can't install an operating system with soft...

Today, we're looking at a real life IT disaster that happened just a couple of weeks ago. It involves the Expresscrypto cryptocurrency microwallet service that could possibly go out of business because its IT administrators didn't see the need to implement a proper server backup strategy.

Demystifying firewalld

Просмотров 15 тыс.2 года назад

Red Hat's firewalld is a firewall management utility that comes on all Red Hat-type Linux distros such as CentOS, AlmaLinux, Rocky Linux, Oracle Enterprise Linux, and Fedora. It's also available as an option for certain other Linux distros, such as Ubuntu. The reason that firewalld has been such a mystery is that Red Hat has never documented how it really works under the hood. Never fear, the B...
