I was curious as to how the licensing for these work--is it just registered to 'generic' instead of a user's name? Or does Blonde Guy personally press each one after the person purchases it?

IRC is quite enough, me thinks :)

Just joined to #netlabs, which I have forgotten to do, but this was good reminder, thanks!

:D
I was actually meaning to bridge the OS/2 IRC channels into the discord (but of course I'll need permission from the IRC channel managers). Why not have both, I say.

Does Discord have an OS/2 client? If not then I see no sense to use it for communication. As well as Telegram, Matrix etc. But Telegram
previously had a web client. Slack had both a web client and gates to irc and jabber. Now these gates are gone away, and web client no
more works with OS/2 browsers. telegram web client too. Though, I'm still using Slack via Bitlbee IRC to different IM networks gateway,
which I run on my Linux VPS server. So, I can connect to it with a simple IRC client from OS/2. Besides Slack, Bitlbee has transports
to ICQ, Jabber, Skype, Telegram, Facebook, VK, Twitter, etc. Of course, voice and video calls are unavailable from IRC, but usually text
is sufficient.

Yeah I did use discord on OS/2 via firefox--although, it *really* needs the falkon Qt5 refresh.

I had two PC Server 500s and one PC Server 720.  They were way too bulky to keep around and are long gone.  I did keep two PS/2 Server 95As since they are about half the size.

I happen to own a model 95 (non-A), but it was much easier to obtain in contrast to the PC Servers :(
It was 'fun' manually building a new SCSI drop cable since the MCA corvette uses a mini centronics on the card-side, which of course is an IBM-exclusive thing and not standard on any SCSI drop cables.

And you actually had a PC Server 720??? Ah sheesh. I guess I was born in the wrong era; they are now inobtanium, couldn't find any even in 2013. It would be a dream running multiple Pentium 1s on the Corollary C-bus II. And some models also had the dual MCA/PCI bus slots.

I'll just go cry on my IntelliStation POWER 185 :p

When I read about this, I thought it would be funny to create a new linux distribution skinned as OS/2 bundled with 2ine called "Gen/2" (to play on GENTOO and OS/2).

I had an IBM PC Server 500 data server in use from 1995-2013.  It just kept on, keeping on.

Oh.... I'd sell a kidney for a PC Server 500 (or even 720).

Started an OS/2 Discord if anyone was into that kind of thing: https://discord.gg/bRJ9gya
May link it up to IRC in the future, we'll see

Networking / Re: Intel 2915ABG on a T41 with OS/2 (questions)
« on: June 01, 2018, 03:09:06 pm »
WPA2 seems to work fine on my T42, using  Intel 2915ABG (known to GENMAC as an 8086:4220). The xcenter widget says I'm using WPA2-PSK.
All I did was create a profile which I named home and fill out the the regular stuff and under the Security tab picked out the "Wi-Fi Protected Access (WPA2-PSK" and entered the preshared key and it just worked.
I did have to manually pick out my NIC driver and still don't have the wired nic working as I haven't had need for it.
According to PCI.exe it's a
Device 4220h PRO/Wireless 2200BG [Calexico2] Network Connection and seems to work as fast as my LTE Internet connection allows or close enough.

Edit, My Internet hub says it is using WPA2(AES)-PSK which was the default.
*Gasp* well that's a relief! I'll just disable physical ethernet in the BIOS so that there's only one NIC connection (The wireless adapter). I'm thinking I'll just reinstall OS/2 on a different hard disk to test things out.

Although now WPA3 was just announced so... I suspect WPA2 stuff will (eventually) be retired.

Networking / Re: Intel 2915ABG on a T41 with OS/2 (questions)

I have a Broadcom wired NIC, and an Intel 2915ABG (known to GENMAC as an 8086:4224) in my IBM ThinkPad T43, Installing ArcaOS (I have done both 5.0 and 5.0.2) finds, and properly installs, both drivers (multimac MMBGE for wired, and GENMAC for WiFi). GENMAC will NOT use WPA2 for WiFi, but WPA works fine. The same windows driver, in XP, will use WPA2, so that problem is something in the GENMAC base (and that is not likely to get fixed).
Oh that sucks... I was intending to use the laptop at work on the company wifi so, I'd definitely need WPA2. Not a problem! I'll just do the raspberry pi option for work, but in the meantime I'll try everyone's suggestions on getting wifi functional with WPA1 for non-work purposes.

Networking / Intel 2915ABG on a T41 with OS/2 (questions)
« on: May 29, 2018, 08:01:47 pm »
So I finally got my T41 upgraded and thrown back together. The Intel 2915ABG wifi card is installed, and the BIOS has been modded to disable the whitelisting. IBM states in their documentation that the 2915ABG is not supported on the T41, only the T42 and beyond (however I presume that's due to the said whitelisting). The BIOS did complain that an unsupported Wifi module was detected prior to modding the BIOS.

Whenever I boot into OS/2 (ArcaOS) I only see the wired Intel NIC, when I disabled the wired Intel NIC OS/2 then complains because it's no longer present and the way it configures things is very stepped like that.

So... my question is...
Should I reinstall ArcaOS if it needs to see network devices during the installation process to set up? And if I do, how exactly does one get GenMAC going?

I'm presuming that the T41 is in fact compatible with the 2915ABG.

Networking / Wifi bridge for OS/2 machines
« on: May 29, 2018, 07:55:00 pm »
I just realized using a raspberry pi for a cheap wifi bridge would be a good solution for any OS/2 machines that don't have the luxury of having GenMAC or whatever:
https://pimylifeup.com/raspberry-pi-wifi-bridge/

Just an idea. But then really, you could use it for a lot more devices too.

Programming / Re: OS/2 kernel requiring speculative execution patch!!!!
« on: January 07, 2018, 10:47:54 am »
#1 you're using Windows instead of Linux (NT kernel is worse at handling this than the Linux kernel)

Where do you get that info from?

I'm honestly surprised at how pro-Windows people are in this day and age when Windows was traditionally derided for being an unstable bucket of frogs (which it still is).

One of the main reasons is that the KTPI fix implemented on Linux does not require PCID, which means performance won't hit pre-westmere CPUs that much. But not only that the way Windows has to work around the problem is a lot more messy due to the way Windows has everything in paged and non-paged pools--whereas this is not the case in Linux or any Unix for that matter because they're not dementedly designed like NT. Just google it, there's sources out there.

Yea, my understanding is that the way OS/2 manages its memory, getting access to kernel memory isn't that big of a deal as we don't have permissions or sandboxes so just need to read a different tabs memory or even the swap file if one exists.
As for the code, it seems to have to be tight assembler, which, as you say, has to target OS/2 and be delivered.
There is a proof of concept using Chromes JavaScript JIT but even that would have to be targeted as there are many code paths in the JIT depending on CPU etc.
The real problem is in data centres and such as this allows escaping from a virtual machine or/and getting roots password.

I'd need to see citations or a source test to confirm, because as far as I can tell, it is exploitable on x86 on any OS.

This link has a rather frightening graphic from Epic Games that shows the performance hit for their servers after a patch had been applied

https://www.epicgames.com/fortnite/forums/news/announcements/132642-epic-services-stability-update

Performance will be reduced under the following conditions:
#1 you're using Windows instead of Linux (NT kernel is worse at handling this than the Linux kernel)
#2 your CPUs lack PCID

So it's possible epicmegagames is running NT on pre-westmere CPUs.

We'll have to wait for the embargo on how this works exactly to end, which is supposed to be soon. There are a lot of unknowns, which CPU's exactly, I heard all produced in the last 10 years. Is it just in 64 bit mode? And such.
Speculative execution was introduced on i686, so anything Pentium 2 and onward basically, is affected. It is not just 64-bit as 32-bit Linux is affected as well.

I can't talk for Arca Noae, but I doubt that they're capable of patching this, it's not like they have the kernels source. The OS4 kernel could be patched.

Then OS/2 is should only be ran on AMD processors if it's being exposed to the internet (which is a problem for me since my ThinkPads are Intel that support stuff in OS/2 I use). This is a pretty big problem.

Anyways, in many ways our platform is insecure to begin with. We're always at least a year behind in browsers, which means security holes and the possibility that one tab is spying on another. Things aren't sandboxed, especially the browser, which is our biggest security hole.
On the other hand, I doubt that many people will be writing code to use against the few OS/2 users, there are much better targets. The NSA may be able to log into the Intel management engine or the AMD equivalent and basically run software at ring -1 with complete access to the computer and sooner or later someone else is going to use the same backdoor.
There's also the question of whether this flaw really affects OS/2 as I believe the kernel memory runs in a separate segment, something that is not supported by 64bit mode and I believe gives some protection.
If it affects x86 Linux (which it does) it will sadly affect OS/2. It's not necessarily a problem regarding the NSA or spying (esp. since all of the old CPUs I run OS/2 on don't even have the intel management engine) but the fact that exploitable javascript could steal credentials or your credit card number--and things like that. Which again... means OS/2 on intel won't be viable for anything on the internet anymore, unless someone patches the OS/2 kernel.

Programming / OS/2 kernel requiring speculative execution patch!!!!
« on: January 03, 2018, 04:01:41 am »
So I'm sure many are aware of the news regarding the flaw in Intel's speculative execution in the majority of the CPUs:
https://www.theregister.co.uk/2018/01/02/intel_cpu_design_flaw/

The problem doesn't end there, it affects anything i686 and newer (as this was when speculative execution was introduced):
https://en.wikipedia.org/wiki/P6_(microarchitecture)

Which means, anything Pentium II and newer is affected.

Will ArcaNoae be working on patching the OS/2 kernel with KPTI? Otherwise I won't be able to consider OS/2 a viable OS for going on the internet anymore for anything personal.
