Red Hat Fedora 23 beta now available

Written by 

Red Hat’s Fedora 23 OS is now available in beta for cloud and includes new security features against memory corruption vulnerabilities and buffer overflows.

Open source tools business Red Hat has launched the Fedore 23 beta of it’s Fedora operating system, just four months after the launch of Fedora 22 which included new Docker container updates.

The free, Linux-based operating system based on the Fedora Project's global community , Fedora 23 Beta continues Fedora's mission to serve as a leading-edge open source operating systemis as usual delivered in three editions aimed at cloud, server and workstation users and most of the big changes are this time only being delivered in the serever and workstation versions – cloud users need to wait for the Fedora 23 Atomic Host which should be delivered “in the not too distant future.”

The release under the Fedora.next initiative is built from a base set of packages that include the Linux kernel, RPM, systemd and Anaconda, as well as the updated package manager “DNF.” While many updates and enhancements have been made to these base packages, one of the most significant updates is the use of compiler flags to help improve security by “hardening” Fedora 23 Beta binaries against memory corruption vulnerabilities, buffer overflows and other similar issues. According to the blog post by the Fedora project team that accompanied the launch the changes are more ‘under the hood,’ ‘tweaks’ than major changes but they will “help to provide additional system security.”

As we said earlier the Fedora 23 Cloud Beta has undergone substantial package updates and enhancements to the underlying base Fedora infrastructure, but no substantial new or tweak features are delivered in this release. However there are plenty of new changes in the server and workstation ranges.

Fedora 23 Server Beta

The changes to Fedora 23 Server Beta start with a new role through the rolekit service in the form of a cache server for web applications with the underlying functionality delivered by memcached. This adds to the two previously supported roles, domain controller (powered by FreeIPA) and database server (via PostgreSQL), which were introduced in previous Fedora Server releases. Additionally, rolekit can now be used from the anaconda kickstart to determine what function the server will utilise with the next system boot.

Numerous updates are also provided in the realm of system management and administration, particularly with Cockpit. Some of the key changes to Cockpit include:

•    A basic cluster dashboard for Kubernetes

•    Support for SSH key authentication and support for configuring user accounts with their authorised keys

•    Compatibility with multi-path disks

Workstation Beta users also get new enhancements the biggest of these being a preview of GNOME 3.18. Changes are also included to the Software application, allowing it to update system firmware, and desktop users will also now have access to LibreOffice 5, the latest edition of the open source office suite. Additionally, improvements are included for Wayland with an aim towards making it the default graphical server in future releases.
