Differences between EuroLinux 7 and 8 – changes and novelties in the 8th version

EuroLinux 8

The new version of EuroLinux brings a lot of changes compared to the previous one. In this article, we present the differences between these releases and describe the features exclusive for EuroLinux 8.

EuroLinux 8 – Features

EuroLinux belongs to the Enterprise Linux family of products, which also includes distributions derived from the same source code, namely Red Hat® Enterprise Linux, Oracle® Linux and CentOS. Based on open standards, EuroLinux 8 provides a set of tools for creating, launching and sharing container applications in the basic version. It helps streamline container creation and eliminates the need for bulky, less secure container daemons. The use of the Wayland server significantly improves the security and speed of the graphical environment - in the eighth version, it is still possible to choose the X.Org server (backwards compatible). The way packet filtering is handled has been simplified. In version 7 of EuroLinux, four tools were used for this purpose: iptables, arptables, ip6tables and ebtables. In version eight, they have been replaced with one tool – nftables.

The version 4.18 of TCP network stack used in EuroLinux 8 provides higher performance, better scalability and greater stability. Two new congestion control algorithms are available: BBR and NV, which offer lower latency and higher throughput. New modules, application streams, and profiles greatly increase the flexibility of the target environment. EuroLinux 8 also means greater security and automation of the DNS service, better use of disk space in XFS, the ability to record terminal administration sessions, create snapshots for physical servers and full integration with Microsoft Active Directory.
