This thread is quite obscure and I am uncertain if this post will be viewed by another human.

I am tired of this endless bullshit! I am tired of politics constantly leaking into this board, I am tired of every thread being related to damn security in one way or another, I am tired of idiots leaking into this medium and causing it to cease being entertaining and insightful for the genuinely savvy users, and I am tired of constantly running from corporations and agencies that want to oppress me and take my data, fuck this.

/tech/ has ceased being a medium for discussing genuine software and hardware and has basically become a medium for hiding from corporations and agencies and constantly being paranoid that every fucking electronic device around you wants you dead, it gets old after a while, and you end up using hardware and software which is absolutely useless for daily activities. BUT HEY! This software/hardware protects your freedom, so you should install it!

I want to discuss motherboards, I want to discuss soldering and other techniques for building simple electronics, I want to discuss interesting software applications for performing calculations or visualizing data plugged into it, I want to discuss signal interception using old television satellite dishes, I want to discuss physics and mathematics that pertains to technology, I want to discuss internal compression engines and transmissions (Because this type of shit actually pertains to /tech/).

But I know this is all a dream, imageboards are filled with faggots and individuals who are interested in these types of topics are highly rare, and on rare imageboards such as this, the only people you will find are those who are here because they care only about their privacy and that is all.

There should definitely be more threads about hardware and other branches of engineering. Ironically, even though I am EE student no one in my class is particularly interested in field they study. Drinking and partying comes before everything, it's very tiresome to be surrounded by such people and I have no one to talk with, so I often loose will to do anything. I am also not very fond of forums, since attaching name to your every post is uncomfortable in some situations and I also find forum format more confusing than image board format of discussion. So by all means start a engineering/hacking/lab/whatever thread so that we may discuss about soldering, electronics, mechanics, physics and other things that are different from usual privacy and free software talk.



Requirements for Secure Clock Synchronization Anonymous 10/20/2017 (Fri) 04:12:22 [Preview] No. 11578 [Reply] [Last 50 Posts]
https://arxiv.org/abs/1710.05798

This paper establishes a fundamental theory of secure clock synchronization. Accurate clock synchronization is the backbone of systems managing power distribution, financial transactions, telecommunication operations, database services, etc. Some clock synchronization (time transfer) systems, such as the Global Navigation Satellite Systems (GNSS), are based on one-way communication from a master to a slave clock. Others, such as the Network Transport Protocol (NTP), and the IEEE 1588 Precision Time Protocol (PTP), involve two-way communication between the master and slave. This paper shows that all one-way time transfer protocols are vulnerable to replay attacks that can potentially compromise timing information. A set of conditions for secure two-way clock synchronization is proposed and proved to be necessary and sufficient. It is shown that IEEE 1588 PTP, although a two-way synchronization protocol, is not compliant with these conditions, and is therefore insecure. Requirements for secure IEEE 1588 PTP are proposed, and a second example protocol is offered to illustrate the range of compliant systems.

It's clear neither of you read the article, or didn't understand any of it if you did read it.

If you don't want to sound stupid in the future, refrain from making inane comments based on a cursory reading of the abstract.

Thank you both for your low-quality contributions to the board!

It's clear we don't need to, the proposal doesn't provide one speck of code or mitigations for other forms of attack across the net. If I required extreme time sensitive synchronization, I'd buy clocks, and synchronize them wherever we'd need them. We wouldn't even need the net&cables.

But calling someone something when they aren't interested it's just easier than dismissal.

ideas for saving /tech/ general Anonymous 10/16/2017 (Mon) 07:26:55 [Preview] No. 11561 [Reply] [Last 50 Posts]
We're about halfway through October and about two weeks out from our most esteemed /tech/nician's autistic tantrum over on /operate/:

>>>/operate/7122 it's good reading, he came in with a balloon knot and left with a rectum that you could park a utility van in

so it seems like a good time to reassess the state of the board.

Since October 1st, there have been 0.6 original posts per day on /tech/. I use the term "original" with some reservation, as some of them are just verbatim reposts from 8/tech/. There have been an average of 8.13 replies per day, but most of them were one-line comments or barbs without substance, or memes, or corrections to a previous post. We're averaging about 1 substantive reply per day. Two on a good day. I didn't feel like digging into the numbers any further, but it's my impression that these averages don't even reflect how dire the situation is, as there was a burst of activity at the beginning of the month that has tapered off significantly.

/tech/ is not dead, but it's on life support, and, ironically, none of its denizens seems to know how to service the life support machine.

It would be a shame for this alternative to pigchan and Hiroshima's /g/ to wither through neglect.

Let's brainstorm ideas for keeping this place alive.

More content is needed to spark more discussion. I think we already have some quality posting autists here, what we need are relevant things to discuss. What we really need are some immigrants to bump our levels and help generate content.

I think our best option is to make releases of something to draw users here. The releases would be best distributed via torrent sites with included readmes' pointing here and links disseminated on tech related boards. The question is, a release of what? It could be portables, infographics, mods, lots of options really we just need to decide on something.

Agreed. And I wouldn't have said anything if those few threads/replies we've had recently had been decent, on balance.

lowRISC: another year bites the dust? Anonymous 10/18/2017 (Wed) 05:41:40 [Preview] No. 11571 [Reply] [Last 50 Posts]

I'm pretty sure the lowRISC FAQ said 2016 last year. It didn't happen, obviously, and it was changed to 2017, but we're running out of that, too. Ten weeks left, boys. Is a lowRISC SoC vaporware for another year?

At what point do we start looking to the J-x processors based on Hitachi's SuperH architecture? The last SH-4 patents are expiring this year.

WPA2 protocol attack Anonymous 10/17/2017 (Tue) 06:41:08 [Preview] No. 11568 [Reply] [Last 50 Posts]
https://www.krackattacks.com/

>We discovered serious weaknesses in WPA2, a protocol that secures all modern protected Wi-Fi networks. An attacker within range of a victim can exploit these weaknesses using key reinstallation attacks (KRACKs). Concretely, attackers can use this novel attack technique to read information that was previously assumed to be safely encrypted. This can be abused to steal sensitive information such as credit card numbers, passwords, chat messages, emails, photos, and so on. The attack works against all modern protected Wi-Fi networks. Depending on the network configuration, it is also possible to inject and manipulate data. For example, an attacker might be able to inject ransomware or other malware into websites.

>The weaknesses are in the Wi-Fi standard itself, and not in individual products or implementations. Therefore, any correct implementation of WPA2 is likely affected. To prevent the attack, users must update affected products as soon as security updates become available. Note that if your device supports Wi-Fi, it is most likely affected. During our initial research, we discovered ourselves that Android, Linux, Apple, Windows, OpenBSD, MediaTek, Linksys, and others, are all affected by some variant of the attacks. For more information about specific products, consult the database of CERT/CC, or contact your vendor.

The Q&A is worth reading, and has information on attack mitigations. Unfortunately, if you are using an Android smartphone that isn't receiving updates anymore, your WiFi security on that device is probably null.

Sounds like the plot to Aerannis. It's some inventive stealth game, although 2D stealth games are getting so good lately I doubt it holds a candle.

Bit torrent and P2P communities will be what temporarily saves the internet for past and current generations. Future generations won't know anything about the current internet and less than 1% will ever use P2P software rendering the internet into commercialized networks much like we see on TV.

I agree, backup everything and make sure you have multiple backups. But this won't save the internet forever as the mindless public capitulates to the total destruction of everything that made the internet so great.

If the original intenet ever goes, I'll go with it, and I won't be buying a bunch of "smart" tech or other commercialized crap. I'll be reading books, watching DVDs, throwing darts and drinkin' booze from a jar again. Going back to simpler times like the early 80s.

Who agrees?

Yes, they are consumerist bullshit and there are dozens of corporations attempting to market them to potential buyers, but one cannot truly appreciate classical music until they have listened to it in real life or with high quality headphones with sound of that seen in real life.

From 1:40-2:10 there is a crackling sound. What on earth is that? Is that track meant for more bass heavy headphones or are my headphones just crappy? Most music sounds great, it's just certain tracks.
