Superb Mini Server
Superb Mini Server (SMS) was a Slackware-based server distribution with web, DNS, DHCP, file, print and fax servers, iptables firewall, mail server with spam filter and anti-virus scanner, and BitTorrent station. It also includes Webmin, a web-based administration tool, but no graphical desktop. SMS, which comes with Slackware's text-mode system installer, was built using Linux-Live scripts (from Slax) and can be used as a live CD for testing purposes.

Happy New Year! We start the year with the announcement about the release of Qubes OS 4.0.2, the latest update of the project's security-focused Linux distribution which allows users to "compartmentalise" computing tasks into isolated compartments called qubes. The new release updates the Linux kernel to version 4.19.89: "We are pleased to announce the release of Qubes 4.0.2. This is the second stable point release of Qubes 4.0. It includes many updates over the initial 4.0 release, in particular: all 4.0 dom0 updates to date; Fedora 30 TemplateVM; Debian 10 TemplateVM; Whonix 15 Gateway and Workstation TemplateVMs; Linux kernel 4.19 by default. If you installed Qubes 4.0 or 4.0.1 and have fully updated, then your system is already equivalent to a Qubes 4.0.2 installation. No further action is required. Note: at 4.5 GB, the Qubes 4.0.2 ISO image will not fit on a single-layer DVD (for the technical details underlying this, please see issue #5367). Instead, we recommend copying the ISO image onto a sufficiently large USB drive. However, if you would prefer to use optical media, we suggest selecting a dual-layer DVD or a Blu-ray disc." See the release announcement for further information. Download: Qubes-R4.0.2-x86_64.iso (4,607MB, SHA256, signature, torrent, installation guide, pkglist). |

| About Qubes
|
| Qubes OS is a free and open-source, security-oriented operating system for single-user desktop computing. Qubes OS leverages Xen-based virtualization to allow for the creation and management of isolated compartments called qubes. These qubes, which are implemented as virtual machines (VMs). This allows each component of the operating system to be isolated from other pieces, preenting compromises from spreading or information from leaking.

Distribution Release: Qubes OS 4.2.2 |
|
The Qubes OS team have announced a new update to the project's security-focused operating system. One of the significant changes in Qubes OS 4.2.2 is an adjustment to how files are transferreed between isolated envirnonments, called qubes. "Qubes 4.2.2 includes a fix for #8332: File-copy qrexec service is overly restrictive. As explained in the issue comments, we introduced a change in Qubes 4.2.0 that caused inter-qube file-copy/move actions to reject filenames containing, e.g., non-Latin characters and certain symbols. The rationale for this change was to mitigate the security risks associated with unusual unicode characters and invalid encoding in filenames, which some software might handle in an unsafe manner and which might cause confusion for users. Such a change represents a trade-off between security and usability. After the change went live, we received several user reports indicating more severe usability problems than we had anticipated. Moreover, these problems were prompting users to resort to dangerous workarounds (such as packing files into an archive format prior to copying) that carry far more risk than the original risk posed by the unrestricted filenames. In addition, we realized that this was a backward-incompatible change that should not have been introduced in a minor release in the first place. Therefore, we have decided, for the time being, to restore the original (pre-4.2) behavior by introducing a new allow-all-names argument for the qubes.Filecopy service. By default, qvm-copy and similar tools will use this less restrictive service (qubes.Filecopy +allow-all-names) whenever they detect any files that would be have been blocked by the more restrictive service (qubes.Filecopy +). If no such files are detected, they will use the more restrictive service." Additional information is available in the release announcement.

Distribution Release: Qubes OS 4.1.0 |
|
Andrew David Wong has announced the release of Qubes OS 4.1.0, a major new update from the project that focuses on Linux operating system security by isolating computing tasks into separate "qubes". This version brings a variety of improvements, bug fixes and component updates: "At long last, the Qubes 4.1.0 stable release has arrived. The culmination of years of development, this release brings a host of new features, major improvements and numerous bug fixes. The GUI domain is a qube separate from dom0 that handles all display-related tasks and some system management. This separation allows us to more securely isolate dom0 while granting the user more flexibility with respect to graphical interfaces. Qrexec is is an RPC (remote procedure call) mechanism that allows one qube to do something inside another qube. The qrexec policy system enforces 'who can do what and where.' Qubes 4.1 brings a new qrexec policy format, significant performance improvements, support for socket services and policy notifications that make it easier to detect problems." Read the rest of the release announcement for a complete list of new features. Download (mirrors): Qubes-R4.1.0-x86_64.iso (5,679MB, SHA512, signature, torrent, pkglist). |
