Help! Trans or diff for increased max speed??

I can give you some insider history on wireless routers many don't know about as I'm in the business.

The FCC (don't quote me on the regulation) added regulation to prevent flashing of custom firmware on home wireless routers unless it's hypervised which means they still have their firmware as the host of the routers so they can still track and spy on everyone. The Asus Black Night was one of the last routers made where you could flash your own custom firmware as the host firmware completely overriding any back doors they have. This was done maybe 10-15 years ago.

Since then I've decided to only run PFSense or a full PC as a router. You get better bandwidth as many of those routers are limited to only 200Mbps due to CPU limitations. So you may have a 1000Mbps connection but are only using 1/5th of it. A 15 year old PC will have more CPU power and will give you a full 1000Mbps connection easily. There's now OPNSense and others out there which bypass the FCC regulations and only the people in the know are making use of this loophole.

With that there's also basic CPU loopholes. All CPU's run an OS called "Minix" and the Intel Media Engine makes use of it. The OS runs a webserver which can turn on and off Harddrives quietly if you have an SSD. Without turning on or lighting up your PC and can access your files. This has been done since the Pentium 4 CPU. Government can access it as they please. Routers with backdoors in their firmware are one piece of the puzzle, and allows them in to your house to reach your PC's with compromised CPU's.

PFSense can block them for now. That is until 5th Generation networks.

5th and 6th and beyond generation networks will have a "Mesh" network which will bypass your PFSense or wifi router security by accessing your 5th gen Intel or AMD CPU via your homes smart meter, samsung refrigerators, 5G mice. Anything with a 5th gen + will relay access off of them to reach other unreachable devices. So now that everything is meshed your bypass efforts are no longer feasible.

This is how our privacy has been violated by your government and continues to do so.

The only way you could block them now is to have a house underground 5ft under earth, with your smart meter far outside above ground to where nothing from inside your house can reach the smart meter. And no one is doing that.

I'm familiar with most of that, which is why I've been running AMD almost exclusively for my adult life. I've got a tomato-router in a box somewhere, and I only use hardwire connections. The only laptop I've got is something like a celery-3 Toughbook, and the only OS I've been able to get to work on it is Slackware 13.37. Oh, and I've been a linux-**** since Win2K was considered "up-to-date".

Yes, AMD has the TrustZone nonsense, but that TEE primarily compares to Intel's SGX system instead of the Intel ME/AMT systems. (For now.)

I've installed PFSense before, and I'd like to play around with OPNSense, and whenever that happens I'll also probably build a PiHole to act as my DNS server, unless I can also run that system on OPNSense.

I've been aware of the security flaws of mesh networks since my time in the military--I was a LAN admin on a submarine--and while I'm not completely opposed to mesh networks, they have a place, and it's essentially on their own critically-crippled subnet that can only talk to itself, and is something that should really only be used for things like a distributed BMS-system for a land-mounted solar network, things like a water-pump for a well in your own land, and other things that have no real business talking to anyone or anything other than one or two other items so they can do their job(s) with some degree of focus.

And I don't have a smart-meter on my home.
I also have a large hat made of tin-foil; I used to work with spooks doing (quasi-)military stuff while I was in the military. It actually takes a lot more work now to actually be safe, secure, and private than ever before.

I really dont worry about the consipriacy theory stuff much.. but wifi definitely is not secure.. none of it is.. ive dont sa lot of laying around with the concept of hacking into supposedly secure wifi and its not hard to do..


whether the microcode on CPU's sends info to the government or not is just consirpacy theory stuff in my book...



I run a lot of linux based stuff on intel and AMD.. ive put oscilloscopes on network connections before and never come across any wierdness such as data going out that the software didnt catch.. ive decompiled and disassembled firmware for various NIC chips and never really discovered anything alarming..



high level software like microsoft windows or apple MAC OSX, and the phone operating systems may very well do this type of stuff sicne its easy to hide.. if linux was doing it im sure someone wouldve called it out on the source code by now... same with tomato or such.. i use a lot of Mikrotik in the field and have to lock the heck down o ntheir firewalls but otherwise they run clean on a linux based OS.. you just have to do your homework on writing firewall rules to close down all the API's they seem to leave open by default...



how did a thread about gears and transmisisons turn into wifi routers?

Ahhh, the meanderings of conversations; who can tell.



I think the conspiracy theory is that there's essentially a host OS in-built to the CPU up in the microcode, but I'm not sure that I believe that, since I think someone would've blown a legitimate whistle on that by now. I mean, yes, I fear my government, but I also fear facebook more.



But then again, I don't even like using SystemD on linux and vastly prefer my old init scripts for the sake of simplicity and security and the same old reasons.


In the end, though, I think it's all just the engineering mindset that goes into things. I like the KISS method, and using one good tool for one job, and then letting other tools handle the other jobs.

 

[cadillackid]

Don’t get me started on systemD!!

 

[nikitis]

Don’t get me started on systemD!!

Me either. lol. I feel you on that. SysVinit would have been better than systemd.

But it is a conspiracy, just not a theory. There was and still is an article on the Minix OS running on CPU's.

Google has also called it out in the past but that article was removed.


See here for the Minix item. Written in 2017:

I see you guys, and I appreciate you.


Currently running a manjaro distro while working on an Arch/LFS build for my main workstation.

 

[nikitis]

Since we’re on the Linux topic. (I use Manjaro as my main driver currently). And to get the topic back in track, have any of you messed with a CAN bus emulator for Linux?

I’d like to make a pi version of my 3box for a replacement computer to potentially keep these buses alive forever, and also easily emulate J1939 as well for transmission upgrade option.

I don’t see why a raspberry pi couldn’t take on both networks.

 

[Albatross]

No, but the idea is interesting.



There was a guy in here about a year ago who was talking about his network build on his bus that seemed like he might have some of the 1337 skillz necessary for such a hack. It could've been a year-and-half, I'm not so great with remembering time-frames, as I generally use the sun's or the moon's position to keep track of what time of day it is.



While I've got a 5900X with 128 GB of RAM in my workstation rig, I generally only tax it's resources recording audio or opening chromium.

 

[cadillackid]

since i use the pre bult comms boxes.. copperhill / advantech.. writing the code to make the 2 talk to each other is easy.. i know I did some of it in opne of my transmission threads.. where i manipulate the engine to transmission data...



I used a Pi4 but the Pi5 is even faster... using one of the communicator modules makes it so you just deal with the data parsing and not have to mess with the actual low level comms of the CAN timings and levels...



as for making your own ECM... theres no reason.. theres so many single box systems out there still and so many single box computers.. id get the harness and comoputer, and convert the thing to single before id try to build a 3 box for something thats niche at best.. we wrent talking about trying to keep someone's 70 chevelle running, we are talking about computers that are 27 years out of production for work trucks that people junk when they break... theres a lot of engineerng more than just the being able to fire the injectors... you have to also get into excatly how and the exacts of the calibrations as well which is a whole other piece.. something that the likes of several tuner companies have spent countless hours on and they arent controlling the HEUI system at its roots just manipulating the tables a bit..



could you build an ECU? most likely you could.. though I likely wouldnt run anythign with a high level OS on it like linux... your wait to start would be a boot up time.. most ECU's in vehicles ran ATMEL based micros... some did run motorola.


the code has to be compiled down to near perfecrtion and you need a ton of safeguards in it so you dont nuke your engine...



you have to be able to account for such things as slow response to your IPR in cold weather, reading the timing wheel and being able to detect if you are getting erratic readings. how will you handle misfires in your RPM calculations.. of course all the normal stuff..


you can probably start hanging out around the megasquirt community.. that is a DIY ECU for gas engines.. some people I guess have gotten a diesel to run on it but not a HEUI.. but anyway you can learn alot about how the workings of the hardware and software in an ECU operate.


ive used mega in the past on a small block chevy and it was a lot of work but versatile and I learned a lot about engine control...



again I dont see why in this case when it could be cnverted to single box.. theres nothing about the truck or bus itself that prevents a conversion.. yes its a lot of work but so is building your own ECM

Well was there ever a guide made for doing it somewhere?

 

[cadillackid]

nada... there also was never a detail chronicle on swapping an AT545 for a 2000 series till i made one...



i dont have a 3 box IH to make the change to so its not something I plan to do...


I only mention as a pathway toward being able to later service your bus that doesnt involve reinventing the wheel...



just like allison 2000 swaps will eventually be moot as everything skoolies buy (except for a straggler) will already have an electronic overdrive transmission..
