Warpstock 2018, Calgary

Arca Noae at Warpstock 2018 in Calgary…and an ArcaOS Sale

This year’s Warpstock event is scheduled for September 14-16 in Calgary, Alberta, Canada.There will be several sessions devoted to getting the most out of ArcaOS and OS/2, in general.

To celebrate this year’s event, Arca Noae will be running a sale on ArcaOS personal and commercial licenses for the duration of Warpstock, Friday through Sunday. This is a great time to get in on this fresh and exciting OS/2 release or to pick up additional licenses for more stations. ArcaOS 5.0.3 was recently released, and the first beta for 5.0.4 is already in testing. Version 5.1 is scheduled for release in 2019, with a host of new features planned, including NLVs for several popular languages.

More information about Warpstock, its history, past speakers and presentations, and this year’s event may be found on the Warpstock site.

If you can’t join us in Calgary, be sure to watch the live feed on the WarpEvents page on YouTube.

Once there, locate the WarpStock 2018 Live Stream URL.

Users with OS/2 can watch the stream in two ways:

  1. Firefox with Flash pointing to the WarpEvents site; or
  2. Grab the YouTube URL and play it in VLC (preferred; get the latest VLC, ported by KO Myung-Hun, from Hobbes).

To ask questions during the live event, use the #netlabs channel on IRC.

There will be up to date information on OS/2 World and the following social networks:

Arca Noae FAT32 driver added to subscription content

With the release of ArcaOS 5.0.3, Arca Noae included a new, slimmed-down version of the OS/2 FAT32 driver. This driver is based on the same code as the Netlabs FAT32 driver, but with non-FAT32 support removed. In other words, it is just a FAT32 installable filesystem driver.

Arca Noae provides support for this FAT32 driver, and the installable package is available is available for both the OS/2 and eCS Drivers & Software subscription and the ArcaOS Support and Maintenance subscription. Just log into your account and visit your subscription order page.

This driver is not an upgrade. It includes a complete vendor change, requiring the existing driver to be uninstalled first before installing the Arca Noae driver. Note that uninstalling any previous driver will remove critical elements from the PATH and LIBPATH statements in CONFIG.SYS. Please review the uninstall actions in WarpIN carefully before proceeding, and always have a backup of critical system files available.

More information is available in the Arca Noae FAT32 wiki.

Don’t have a support subscription? Have non-ArcaOS OS/2-based systems and want new drivers and software? Please visit our store.

Support FreeRDP for OS/2!

If you have a need to access a remote Windows desktop, the best option is using a Remote Desktop Protocol (RDP) client. Using RDP, the local system’s drives may be mapped (redirected) into the remote system to access local files, and even audio from the remote system may be redirected to the local system.

Currently, the RDP client of choice on OS/2 is RDesktop, ported by Andrey Vasilkin. However, RDesktop is showing its age, and a newer, more active project, FreeRDP, has become very well known.

Andrey proposes porting FreeRDP to OS/2, which poses its own set of challenges, so in order to do that, he needs support from the OS/2 user base. This project will take several months, but when he is done, all users of OS/2 warp, eCS, and ArcaOS will have a free, modern, remote access tool.

Sponsoring units for this work may be purchased in the Arca Noae store, in $15, $25, $50, and $100 increments, and of course, it is possible to purchase multiple units at one time.

As with all of the sponsoring collected through Arca Noae 100% of your donation (subject to currency conversion) goes to the project or to the developer. Arca Noae absorbs any related transfer fees.

Policy statement concerning Spectre and Meltdown exploits

Spectre and Meltdown are terms used to describe two potential exploits in a class of security attacks commonly termed “timing attacks” because they access data which may be sensitive in nature (passwords and other information) from areas of memory which may only be available at specific times (either moved elsewhere or removed entirely at other times). They belong to the more general class termed “side-channel attacks,” because they exploit the hardware itself, rather than breaking encryption or utilizing a software flaw. For more technical information regarding these exploits, please refer to the links section, below.

Arca Noae engineers are monitoring the situation, and while there is still much contradictory information crossing the internet at this time, we believe we have been able to assess at least some of the risk and provide some guidance to users of the OS/2 platform (OS/2 Warp, eComStation, and ArcaOS). As further reliable information becomes available, this post will be updated to reflect any change in Arca Noae’s position and any actions we may plan to take.

General information

In order to gain access to any information in privileged memory using one of these exploits, a user-level application must be launched on the specific machine to be compromised. This means that presently, an OS/2 executable must be used as the attack vector. As of this writing, we are not aware of any such code which executes on the OS/2 platform.

Browser-based attacks (running JavaScript) appear to require greater precision in a high-resolution timer than is currently available on OS/2, making such exploits more difficult than on other platforms, if not altogether impossible. It should also be noted that any such JavaScript-based attack would have to also be specifically designed to handle access to memory regions as managed by OS/2 (in other words, a malicious JavaScript program must be written for OS/2 and specifically to run in the OS/2 browser version in which it is running; a JavaScript program written for Windows or Linux will not work on OS/2). Realistically, the chance of this level of coding detail is extremely small.

Risks – virtual installations vs bare metal

By far, virtualized environments (running OS/2 as a guest under some other more vulnerable platform) are at the greatest risk, because the host system may rightly have access to the guest’s memory and virtualized processor. A host running a vulnerable operating system with an exploitable CPU which remains unpatched is the greatest concern. Arca Noae believes bare metal installations of OS/2-based operating systems are at much less risk.

Arca Noae’s current strategy

To date, we have not identified a need for a kernel patch to mitigate the risk of any hypothetical Spectre or Meltdown attack against OS/2-based systems. We continue to monitor the available information and will adjust our strategy as conditions require.

Arca Noae’s current recommendations

For virtualized and bare metal installations, Arca Noae recommends only running software obtained from trusted sources. Per stand practice, reasonable security precautions should be taken when accessing the internet, particularly when visiting unfamiliar or untrusted sites, and browser cache should be cleared regularly. The use of a NAT firewall is also encouraged (either a separate one, as built into a broadband router or at a minimum, a software firewall running on the local OS/2 system, such as InJoy Firewall).

Because a malicious application designed to utilize one of these exploits would have to be downloaded or copied to the target OS/2 system and then executed locally, normal malware protections remain the best first line of defense.

For virtualized installations, Arca Noae recommends applying to the host system whatever patches are made available and recommended by the developer of the host operating system.

Updates

2019-02-14: Security researchers apparently conclude in this whitepaper that Spectre cannot be entirely mitigated at the software level.
