Very tired nerd who doesn’t know how to speak correctly
Ask me about floppa, Plan 9, or computer architecture or anything computers really (if you want)
:cat-vibing:
If I don’t reply to you it’s probably cuz I’m too tired, sorry :(
I uhh wasn’t literally about to go do this or anything…
He rented all types of servers around the country in the cloud and designed a denial of service (DoS) attack
What a uniquely skilled individual!
His feat did not go unnoticed. Over the next year he had meetings with officials from the United States Cyber Command, the branch of the armed forces dedicated to this field. He also met with officers from the Marines, the Space Operations Command and intelligence (NSA). Cáceres shared with them the keys to his successful operation and told them that, in his opinion, similar operations could be carried out with small commandos of two to four hackers. That would give them agility, autonomy and the ability to react.
Me, a cyber-commando, dressing up in full tactical gear, ready for anything, for the trip from my gaming chair to my refrigerator to get beer while I watch my rented Azure servers send spam to a small country’s routers
He tried, but failed. “To do anything you need authorization, which takes six months to get. And when you get it, what you wanted to do no longer works. That is the reality here in the U.S.: we have very, very good people working on our cyber defense, but they are hogtied. They can’t do anything, even though I know we have the resources to do a lot.”
Smh our bureaucratic government won’t approve my request to start a war with the DPRK from my couch
If he did this to any other small nation, especially a US-aligned one, he would be charged with a serious crime. The US can’t openly do electronic warfare but they can stand by and watch this clown do what basically amounts to cyber-terrorism, a least for a little while
Anyway, now that he doxxed himself I hope the DPRK actually gives him something to fear lol
Also
And ever since he took down the internet in North Korea, he has also been approached by the National Security Agency (NSA). Everyone wanted to know how he did it.
Lmao
This is peak journalism, they obviously took him at his word
Why don’t they just move to El Salvador if they like Bitcoin so much
Plan 9 posting
deleted by creator
We are so back
OpenBSD, RISC-V, and 9front mentioned?
Haven’t listened to BSDNow in a while, but maybe I’ll listen to this episode
If we can somehow figure out how to distribute a web browser across all 4,032 nodes of a supercomputer containing 145,152 processors, I’m down, we’ll definitely need it if we aren’t using ad blockers
I suggest we figure out process migration for the Plan 9 kernel
We could make our money back if the RSA factoring challenges were still being paid, we would prob have enough computing power and people involved in a group buy to figure out some kind of improved factorization algorithm together
Just dreaming…
Group buy, anyone?
You can check to see what drivers were compiled as modules or into your kernel by reading the kernel configuration at /proc/config.gz
or /boot/*config*
There might also be out-of-tree (not included with the kernel) drivers installed as packages on your system but this is very rare outside of like… having an NVIDIA card and running the closed-source vendor driver
The vast majority of drivers are included with the Linux kernel now (in tree) so the difference usually comes down to kernel version (newer kernels have more drivers, of course) or kernel configuration set at compile-time (this can be anything from including or not including drivers, to turning driver features on and off, or more fundamental changes beyond drivers)
You can get kernel version info from uname -a
and a lot of the time, probably most of the time (this is also down to configuration), you can get kernel configuration info from /proc/config.gz
(use gzip -d
to decompress) or something like /boot/config
Then you can run diff
on configurations of 2 different distro kernels you’re interested in to see how the 2 distribution’s kernels were set up differently
This could also be caused by different setups of userspace tools or UI that interact with these drivers in different, sometimes worse ways but this is usually much less likely in my experience (most Linux distros do things like this the same way these days tbh)
Oh, also, there are a lot of drivers that require vendor-supplied firmware or binary blobs to function and most of the time distros don’t bake these into the kernel (although it is possible) and different distros might have more or less of these blobs available or installed by default or they might be packaged differently. The kernel should print an error message if it can’t find blobs it needs though
I guess there’s kinda a lot to consider lol. Sorry if all of this is obvious
What hardware are you talking about specifically?
Ohh that’s true, I didn’t think about that. It would be difficult to route anything through it unless you were connected directly to it with nothing in-between because no other router would forward packets destined for somewhere else to my machine (except maybe in the extremely unlikely case of source routing?). It seems obvious now lol, thank you!
I’ll write some firewall rules just in case
Out of all the parasites capitalist society has produced, Nestle executives possibly deserve the the most
I see. Our motherboards have different chipsets (I have an X570 in mine). It probably has nothing to do with my issue…
Hoping those kernel parameters fix it. I wish I could help further. PCs are just a bottomless, mostly undocumented rabbithole :(
What motherboard do you have? Also what happens exactly when the lock-ups happen? Have you ever been playing audio when the lock-ups happen and does it loop or stop or keep playing?
I recently had to “fix” (workaround) a similar issue in the OpenBSD kernel with a specific hardware peripheral on my PC (running a 2nd-gen Ryzen), the High Definition Audio controller. For whatever reason (and only when I was running OpenBSD) interrupts from the HDA controller (to let the CPU know to refill audio buffers) would just randomly stop making it to the CPU and audio would loop for a few seconds and then shut off. I spent a long time trying to figure out what causes it and reading Linux driver code but I couldn’t find a cause or why only OpenBSD would trigger it. I ended up having to write kind of a hacky polling mode into the HDA driver. My only guess is some of these AMD-chipset-having motherboards have faulty interrupt controllers.
Maybe there is a similar issue with your system and timer interrupts aren’t making it to your CPU or something. But I’m not really an expert on PC architecture and idek if it even works like that on PCs lol
Sorry for so many questions but do you also have any kernel logs available from when this happens?
I simply do both
It’s not working
