#

why i'm gonna check. it might be fine, and just a massive production consistency issue

#

but yea, def checking since the nasty one he was showing is a corsair one

#

most i've gotten my 4090 up to is 325W

#

but would that matter?

pure karma
#

4090 was melting too so.... yes?

#

if its a cable issue its just a question of more pins being bad to reach the melting point and not just a power thing no?

#

obviously more power will make it worst but like its not everything here clearly

languid gulch
#

true

#

anyway, gonna go check and see how bad it is

#

brb

pure karma
#

im too lazy to check mine not to mention if repluged it like 5-6 times now so im just reducing my chances checking

languid gulch
#

yea, this was important enough of a thing to make me want to check it

#

luckily, everything looks decent, and my gpu has the little LED to let me know if it's properly seated/connected

#

and it's an H++ one

#

and nothing was slidy when i fiddled with the cables

pure karma
#

Honestly the only thing im woried about is the weight since mine is entirely held up by the conector

languid gulch
#

oh yea mine has the floor jack & it 100% makes a difference

pure karma
#

guess while im at it i may aswell replug my front usb c for the 70th time

#

It is so trashed and holding on for deer life

#

Dangit i forgot my phone cant upload video cause its dumb

languid gulch
stray badger
pure karma
#

i mean i could atach it if i had somewhere to but yea some kind of mount would be good

pure karma
# languid gulch

the worst part is thats basically what my pc is a bunch of jerry rigged jank that just works colectively

languid gulch
#

i called my previous build Frankenputer

pure karma
#

like my gpu mount isent screwed in because its the wrong threads so its just sitting in the holes...

#

and even then one of the standoffs is bent like 30 degrees so its a single standoff doing everything

languid gulch
#

at one point i had a sata ssd hanging by its cables

pure karma
#

well thats just the laptop user experience

#

400 usb devices and a hanging sata drive

languid gulch
#

my first aftermarket cooler was a v1, and it was right when ryzen came out, so they just sold an adapter kit for it & it was an updraft cooler

charred relic
#

I didn't even look at that connector on mine because I knew I didn't need it anyhow

languid gulch
#

well, a vertical airflow cooler, fan was right above the gpu

pure karma
#

its literally just sitting on top of my gpu unpluged now because i dont feel like turning off my pc to plug it back in and honestly im tempted to just leave it there

charred relic
#

Also if you have that much plugged into a laptop get a dock heh

#

then you can plop it down and plug in one cable

languid gulch
charred relic
#

I'll probably get a decent dock for my i

languid gulch
#

they'd randomly kick off & on, and the centrifugal force started rotating my laptop stand

charred relic
#

iPad

#

I have a keyboard case but i like being able to get it hardlined and powered when im in certain places doing certain things with it

#

like if im using it for music it'll be nice being able to dock it to all that gear

#

I've decided the desktop will need a PCIe card to add more

languid gulch
#

i've had good luck with mine

charred relic
#

I don't want to have usb hubs hanging off it

languid gulch
#

5 external, 2 internal

#

want the link?

charred relic
#

I went over everything and realized i have 1 open type-a

#

and i have a couple of things not plugged in

#

no wait i have a type c free back there too...

languid gulch
#

this is the one i use, Inateck

#

$25 doesn't seem too awful compared to others

pure karma
#

why the internal ones?

languid gulch
#

i threw the gigantic xbox dongle on one of the internal ones so it wouldn't snap off

pure karma
#

for like goofy decorations and stuff?

#

or that

languid gulch
#

no idea what else it could be used for, maybe a 2.5" external or something weird like that, just sitting in the case

pure karma
#

having my side pannel off is actually kinda nice

#

gives a nice breeze

#

since i swapped my rad from push to pull

#

so its blowing towards me now

#

gonna be hell in the summer buy ay in the winter its lit

languid gulch
#

just wait till july 🤣

pure karma
#

oh great nintek invented melting display outputs instead

#

genius

languid gulch
#

i mean, at this point why not

#

as someone pointed out, 5090 OC is now measured in terms of HP

charred relic
#

relocated to the work shop, bit cold but whatever

#

Still can't get over this 1oz pack of Kester solder my dad had with a price tag of 1.06 on it

#

It's about 12.50 now. Then again you get ripped off buying 1oz anyhow since you can get 16oz rolls for like 40

languid gulch
#

the costco method of extortion

charred relic
#

Well... they know if somebody is only looking to get 1oz they are likely doing like 1 job and that's it. So they kinda have those types over a barrell

languid gulch
#

yup

charred relic
#

For me buying less than an 8oz roll is a waste of time

languid gulch
#

at least you'll have one to give to your kid in 50 years 🤣

charred relic
#

Solder joints on these boards are small but they add up, probably burn through 1/4 to 1/2oz on an average pedal

#

Way more on something like a decent size tube amplifier which has a lot of high current AC

#

End up with some extra beeft solder joints in there

languid gulch
#

with my talent they wouldn't be beefy but a serious short risk

charred relic
#

Remember kids. The excitement of electronics only comes if it can kill you 😄

languid gulch
#

best i've gotten hit with is 8k volts

charred relic
#

I'll need to be exceeding that for a jacobs ladder

#

Think I'll want like 9k+

#

need a salvage microwave for it's transformer heh

languid gulch
#

mine was on my ancient pickup on its original spark plug wires

#

they were frayed as fuck & shorting on the fenders

charred relic
#

oh those will let you know if they have spark lol

languid gulch
#

lil bit yea

charred relic
#

It's enough to create a plasma arc so...

languid gulch
#

eh, when it shorts it's not quite as bad

charred relic
#

I'm saying in general when you look at the end of the wire you vcan see the spark

languid gulch
#

still felt like one of those electrical muscle exerciser thingies

charred relic
#

that's plasma

languid gulch
#

oh yea definitely

charred relic
#

Why I need so much for a jacobs ladder, I have to jump a larger arc at the end

#

but they sure sound and look neat!

#

(and can def 100% kill you()

languid gulch
#

could you go for a higher voltage one with basically no amps?

charred relic
#

just voltage mostly

#

Since I'll probably do something on the larger size I might need to hit 15k+

#

I just want a 20k watt microwave like that video... so I can cook a hot pocket in under 10 seconds.

languid gulch
#

i think a blowtorch could do that

pure karma
#

just.... light a forest on fire at that point

charred relic
#

But it's moar fun with microwaves

languid gulch
#

fresnel lens would be fun too

charred relic
#

that thing melted tungsten in short order

#

That guys videos are definitely do not try this at home type shit

#

like really.. do not try

languid gulch
#

just have a concrete slab under it 🤣

charred relic
#

I'm gonna end up knocking out power to the entire neighborhood one day...

#

and i'll be out there acting as confused as everyone else 😄

pure karma
#

wasent that a video

#

any of yall got a link to that microwave video

#

i feel like i saw it at some point but now i cant find it

charred relic
#

that dude is great lol

#

If I had to guess I'd imagine his IQ is fairly fucking high...

pure karma
#

yea i knew i got this recomended at some point

#

iv heard of this guy for sure he rings a bell

charred relic
#

He does a lot of crazy projects, usually dangerous heh

pure karma
#

I feel like this is the embodiment of here is why safety rules exist

#

it feels like im watching the weld shop teacher just flinging shit into pots and seeing what happens

#

one time he made a sodium bomb and lit the ceiling on fire

#

He also use to discharge the fire extinguishers as a demonstration IN THE CLASSROOM before the fire marshall got tired of refilling them 🤣

#

idk what's happening, but youtube is completely unusable

#

I've let it load for 5 minutes and its still like this

#

Is there an extension that could fix this?

#

I've tried disabling all my extensions, reinstalling firefox, and reinstalling windows. Nothing works and it always gets this bad after a couple of months

charred relic
#

that's a tough one

who was the one that glazes brave? I forgot. Any brave glazers wanna tell me if google sites are just as slow on brave?

#

It looks like you can't use VLC media player to download videos from YouTube anymore. The server refuses the connection from VLC.
Basically Google found the loophole and plugged it.
Something about HTTP Error 403.

#

Error 403 means that the server is refusing the connection and will not allow one to connect to it.

wanton orchid
#

403 is not server error but ressource error

#

i.e it does not refuse connection
it simply says you're not allowed to get served what you asked for

twin dew
#

There is supposed to be two metal tabs protruding from the side of the pin that lock it in place with some wiggle room:

#

But those can fold backwards with enough force and fail.

languid gulch
#

what about the wire itself?

twin dew
#

That pic is for Molex Micro-Fit 3.0 female crimp terminal, in this case two dimple type with gold plate inside for AWG 24-20 cable, didn't try to find proper one.

twin dew
#

When done properly. Basically that crimp is supposed to be fully air tight and stronger than the strands themselves.

languid gulch
#

i mean is there any crimp that holds the wire to the full plastic casing

twin dew
#

If the wires were somehow fixed to the housing, the terminal couldn't move.

#

Just little movement, so it can align properly with the other sides terminal.

languid gulch
#

yea good point

#

so 2 tiny metal tabs determine whether or not your connection is solid

twin dew
#

But the amount of force needed to fold those two tabs backwards should normally be excessive.

#

But yes, if the two sides don't align properly and you force the housing in, the tabs will fold.

languid gulch
#

i was also thinking that maybe people are pulling the connector out by holding onto the wires a bit too much, even unintentionally

twin dew
languid gulch
#

when i took mine out i couldn't just hold onto the connector, so instead i broke out my ifixit kit and used 2 of the plastic pry tools on either side to back it out

twin dew
#

Because then all the force is transmitted via those small tabs.

languid gulch
#

it's so much more friction than a normal 8 pin to fight with

#

thankfully mine looks fine, nothing loose on it

twin dew
#

Crimp pull testing results, where two in the middle are what is wanted.
But point of crimping is to force the contact and the wire together with such force that you get welding effect between the surfaces

languid gulch
#

i hope they get it right, issue a general recall of all of them, and put out a decent one

twin dew
#

Also, that is the reason for that "Don't bend the cable too close to the connector" thing.
As that will cause excessive force on those small tabs at the farthest pins away from the bend direction.

#

And that "pin depth" thing is about the freedom of movement, when contrained by that wrapping.
There is normally about 1mm of movement for the pins fore-aft.

#

But because that shrink wrap at the end of the wrapping limits the movement of the wires, some will be at minimum, some will be at maximum.

#

But that Corsair cable seems to have loose pin even in the closeups.

#

Just watching the video.

languid gulch
#

oh 100%

#

i just wonder if that's overuse or a manufacturing defect

twin dew
#

He would have needed to pull the wire completely out, and shown that contact.

#

Might have been one that wasn't fully inserted in factory and didn't lock.
Or might have had folded wings.

#

Ah, no, he did push it in to the top position, and then back.
The wings are there, but for some reason the lock level is lot lower than the others.

#

And that first gen did have much more allowance for that kind of thing.
Which was tightened for the new revision.

#

Corsair might be using bad quality contacts with inconsistent wings.
Or contacts from one manufacturer and housings from another.

#

But that amount of slop shouldn't be issue.
As even that worst pin at the max depth is is still way above the level where the pins from card side will go down to.

#

Remember that the card side pins go down to somewhere around here:

#

And the end of the contact surface on the female contact side is here:

#

For that dual dimple one.
Need to find pic of the better leaf spring type.

languid gulch
#

all of it just screams "well, we tried"

#

and also 0 margin for error or it all burns

twin dew
#

So would had needed to pop that specific pin and another one "normal" out and looked at the contacts.
Easy with right unlock tool.

#

So that JayZ video might be real, or just bad take.
He again didn't know enough to fully investigate and just threw gasoline on the fire.

languid gulch
#

jay noticing that it's been the end cables that are burned is interesting, which is why i was thinking maybe people are pulling out the connection with just enough extra force on the cables, unintentionally, to loosen them up like that

twin dew
#

You would need to use very undersized wires to make them heat more than contacts.

#

Ah, you mean the outermost contacts in the housing.

languid gulch
#

right, but having the contacts back out even though the clip is secured in place

#

you'd have no idea it had happened

#

maybe they should start doing a clear connector 🤣

twin dew
#

Yeah, that is where any bad handling by forcing a turn will cause most.

languid gulch
#

just insane that we're 3 generations into this and still finding serious problems, which kinda makes me think that someone might have already known about it

twin dew
#

Turn that cable sideways, and the far pins get pulled.
As the near wires will have too much length, far ones too little.
And because of that shrink wrap etc. only the non-wrapped part of the wire counts.

#

Less there is visible wire, worse it is.

languid gulch
#

yea my cable has none of the extra shrink wrap around all the tiny cables thankfully

#

kinda scary that der8auer was recording 20+ amps going thru one of those

#

it was worrying enough to see it happening across the industry, but now i've been thrown in with it all with the new pc

twin dew
#

Which is the insanity of that connector.
6 pins that all would need to have about same contact resistance to very tight tolerance, or very bad things happen.
As the contacts are without any headroom between the contact spec and the cable/connector spec.

#

And no monitoring to make sure that is actually the case.

#

Well, Asus has that monitoring, but still no automatic action, just user warning in OS.

languid gulch
#

at this point they really should just use a C14

twin dew
#

That is only 15A max.

#

In US, and 10A in EU.

#

So really not suitable.

languid gulch
#

stuff a transformer into the GPU 🤣

#

kinda hoping that someone like GN is able to figure out an easy way to instantly melt the cable in a repeatable way that'd induce a recall

charred relic
#

melt all the things

narrow folio
#

how about the 6 pins are combined into a small copper bar right in the connector and then a single thick wire per bar runs to the other side?

twin dew
languid gulch
#

at this point i wouldn't mind using a fucking bus bar to make a decent connection that won't catch on fire

narrow folio
#

it would not, but the pins would not be pulled sideways that easily

twin dew
narrow folio
#

and the copper bar would make a nice heat transfer

twin dew
#

Problem is using multiple pins to transfer power at near the contacts max spec, without any active monitoring or balancing.

narrow folio
languid gulch
#

it's like they're trying to keep it small, but given the size of the big cards, that ship has sailed

twin dew
narrow folio
#

I just don't understand why this is not done in the first place. the 3090 at least had 3 phases

twin dew
#

More expensive.

languid gulch
#

why do it right when you can do it cheap

narrow folio
#

yeah, the negative publicity about the newest 'flame generation' feature of the top gen GPU surely helps to sell more

languid gulch
#

cornered market

#

and no hints of any antitrust attempts against it

twin dew
wanton orchid
#

imagine splitting that 1 metal bar in 3 smaller joint metal bars

#

that sure would increase cost and size tremendously

#

spoiler : not at all
Nvidia is just fucking lazy

twin dew
# wanton orchid imagine splitting that 1 metal bar in 3 smaller joint metal bars

Meaning the way it was done on 3090 TI.
The separation of VRM to different regions, no cost change.
Being able to monitor the current split, to notice stuff is out of whack, few dollars to few tens of dollars.
Having the ability to switch which input specific VRM gets its power, to be able to do active current redirection, again few dollars to few tens of dollars.

#

So it does cost.
Not that lot, but enough for the manager/exec level to say to skip it as useless.

wanton orchid
#

but that's when it's crazy

#

skip literal 1/1000 of the cost for a huge stability and safety hazard

twin dew
#

Must have that sweet sweet infinite growth...

#

Not only increased revenue year after year.
Not just increased profit.
Also increased profit margin, year after year, forever.

#

Current MBA and stock market thinking, as impossible as that is in real world.

#

cheaper to deal with any lawsuits than make the cards safer

#

therefore you don't make the cards safer

charred relic

We had a Pinto when I was a kid... brand new 😄

#

Looks like slightly below surface level understanding

#

Both have usecases where they are superior to the other

pure karma
twin dew
#

Wire is sized correctly for the contact, and has more headroom than the contact.

#

Oversizing that wire would just make the contact for that wire to heat up even more.

pure karma
#

No ik its sufficient but its half the size to be safe at that power

twin dew
#

When that failure is happening.

#

So oversizing the wire without oversizing the contact would just make the contacts and connector housings to burn even easier.

dire igloo
#

basically: right now, the cable is losing heat too, so there's less heat burning up the connectors.
make the wire thicker and all that heat is lost at the connectors

twin dew
#

Or did I make the same mistake as yesterday again...
In a way I did.
As the total resistance would go down, so the total voltage losses would go down.
So more voltage getting to the cards, so less current for same power.

#

But basically not worth it to overspec the cable if the pin is crap.

dire igloo
#

sounds like network stuff: the connection is only as fast as the slowest link

night girder
jagged snow
#

(not trying to correct you, just adding)

twin dew
#

If the card wasn't upping the current to keep the same power.

#

As the voltage droops.

#

ok, is it possible that having a bunch of usb stuff plugged into the back of my mobo is drawing too much power & occasionally it brain farts & resets it all?

#

every once in a while stuff like a youtube video playing will pause, 2 of my drives will open up, and my bluetooth will reset

charred relic
#

I suppose it would be possible that at times one or more devices draws a little more power leaving everything short... and that could cause devices connected to it to reset

#

I've had similar issues with those usb hubs before which is why I'm going to just throw in a PCIe x1 card to give me more ports. Make sure they're full speed and fully powered.

#

I'm down to 2 ports and I'd like to move a couple of the things plugged into the front to the back.

I also just checked,and this server has no rules on pinging mods

with fiber, no matter what server you choose you should get roughly gigabit right?

I did a couple of servers in California and this was the best I could get

No you'll get whatever the ISP has provisioned on that line heh

#

I have fiber at 600/600, it's cabable of well past 1Gbps though

twin dew
# sage pier with fiber, no matter what server you choose you should get roughly gigabit righ...

No.
With bad ISP you usually get that paid for speed to their first router, if even that.
Anything past that can be way lower.

And almost all big US & Canada ISPs belong in that bad category.

And even with good ISP, the speeds in general Internet, outside of that ISPs own network aren't guaranteed.
Just that good ISPs try to also negotiate transit agreements to give good speeds to large enough amount of Internet to not cause issues for normal users.

#

Because the speed you pay for is at minimum just the line speed to their end of the line.
And from the device you connect there (their ONT equivalent) in a switch, they might oversubscribe a lot already to their first router.

#

Gigabit between ONTs, then 100 subscribers in same switch cluster being forced into shared 10G pipe, (10:1 oversubscription), instead of 100G pipe (no oversubscription).
Or even just 1G pipe (100:1 oversubscription).

#

But when the speed depends on where you are testing to, that is mostly about transit agreements and capacity at transit points between your ISP and other networks onwards towards the target server.

twin dew
visual tree
#

Can confirm since I work for an ISP. Most people think they have their own dedicated fiber and they always get full speed without realizing they are sharing bandwidth with multiple customers

#

Almost all ISP's use PON since it's cost-effective

#

Example for GPON

twin dew
#

And then from that onwards to general Internet.

#

Yes, with GPON, there is also oversubscription in the fiber portion too.
With "classic" point-to-point fiber there isn't, and neither was there with ADSL or VDSL.
Cable modems also have oversubscription in the cable wiring portion.

visual tree
#

My neighbors use ISP which offers DOCSIS (cable) and they had speed issues in the past because too many people were connected to a single street cabinet where the amplifier is installed I think

#

Never worked with cable so I don't know much about it

twin dew
#

With cable modems there is "cell" where the cable wiring is just shared medium connected together and the bandwidth is shared between all subscribers connected to it.

visual tree
#

Also, I recently noticed someone ran over those cabinets and knocked them down and ISP hasn't fixed it yet lol

twin dew
#

Kind of like that GPON, just with coaxial cable being connected together without active ISP side device.

#

One port on ISP side connected to X number of subscribers, with Y amount of the bandwidth in that coax being set aside for DOCSIS, and rest for cable TV.

#

With separate downlink and uplink allocations.

#

Where certain amount of actual internet speed in upload needs more coax bandwidth allocation than same amount of download.

visual tree
#

Found an image online of one of those cabinets

twin dew
#

More TV channels with better quality, smaller the cells need to be to support same amount of subscribers.

Before cable modems, those cells used to be gigantic with just one way signal boosters.

#

With DOCSIS the signal boosters need to be bi-directional, or there needs to be DOCSIS ISP side modem instead at that location.
Or even nearer to consumers to split the old cells into smaller parts to give decent actual speeds.

#

Basically juggling amount of TV channels vs. actual bandwidth against cell size (smaller means more expensive for the cable operator, and possibly needing more cabinets etc.)

visual tree
twin dew
#

But question is.
Do those small cabinets contain amplifiers, or converters from coax to fiber too, for the Internet traffic.

visual tree
#

Haven't seen them opened yet but I think those smaller cabinets only have coax

twin dew
#

Classic before DOCSIS was just amplifiers, with shared wiring between the local cabinet and the disctict cabinet that actually did the TV transmission sending.
And first cable operators just converted those amplifiers to two-directional ones.
But as traffic has grown, usually they either have had to split that district level coax to multiple runs, or just run fiber to each local cabinet and install DOCSIS ISP modems at those.

#

Either to run more coax, or run fiber.

visual tree
#

Damn, can't find an image of the whole cabinet but this one looks like it's from the district cabinet (large one)

twin dew
#

Based on the number of fiber runs in the wall compared to the four actually getting used in this cabinet, I would expect there is coax run with TV signals and fiber run with internet traffic going to each local cabinet.
And then one-way amplifier for TV signals, and DOCSIS ISP modem with fiber connection in the local cabinet.
But cannot know.

#

With those 4 in use fibers being used to send the TV programming to be converted into coax DVB-C signals in that top right large box.

visual tree
#

@twin dew Found it!

#

This one is from the large cabinet

twin dew
#

Passive coax splitter/combiner on right.
Probably four coax amplifiers at the bottom.
And possibly DOCSIS ISP modem on above those.
Left side might be just fiber connection box, splitting those two visible fibers from the black cable going to it from underground runs.
Which is coming from different red ground pipe than the coax ones.

#

Leftmost is probably amplifying the incoming TV feed before splitting it 4-ways, one going with that white wire probably into some kind of filter, before getting used in the rest.
But also being sent in two cables onwards to more cabinets.

visual tree
#

Guess I'm staying with fiber (PON), no active elements and the network structure is easier to understand than DOCSIS 😅

The danger was known, just that some drivers didn't like they couldn't move their heads.

I mean, c'mon that looks ridiculous.

#

If people saw this in a movie, most (who don't know lift) would think it's CGI and bullshit (impossible).

twin dew
#

Yeah, but fast enough plate has lot of lift.
And the underside is basically a plate in most sport cars.
When you aren't in right orientation, the various downforce producing devices don't work and you just get the lift from bottom being in wrong angle.

night girder
#

I understand all the science behind it.

#

But I still find it fascinating to look at.

twin dew
#

Lot of high end sports cars can drive in ceiling once they hit high enough speed.

#

Because if they didn't generate that much downforce, they would be uncontrollable.

night girder
#

Honestly, I spend too much time looking at cars being lifted by air 🤣

night girder
#

The picture I posted. The plate that goes up. And you can see it happen in last gif I posted.

#

You see on the roof, that there is a plate standing in an angle, and then closes.

twin dew
#

The stuff that is engineered to keep the car sticking to the surface when going forward like intended.

#

Because otherwise the pure speed would cause them to lift up like that on any bump, even when going straight.

night girder
#

Oh, but that's just for every car?

charred relic
#

those plates don't do jack unless the care is going backards...

#

and they are basically the same as spoilers on an aircraft wing, tons of turbulence... no lift and lots of drag

#

they have plates on the side too

#

only those need to be working moving foward... if you are moving backards then well.. um.... hmmm

twin dew
#

Yeah, point is to slow the car down fast if it stops going nose forwards, with passively deplying aero-surfaces.

#

So it doesn't get so much airtime once the bottom starts generating lift.

night girder
# charred relic those plates don't do jack unless the care is going backards...

Dr. Eric Jacuzzi walks through the aero enhancements NASCAR is implementing for superspeedway races, starting this weekend at Talladega Superspeedway. The additions to the car are designed to increase lift-off speed, decreasing the chance of a car getting airborne.

Just not perfect?

And that the lift-up at speed if downforce generating aero is lost by going sideways/backwards is thing that happens to all cars at high speeds.
NASCAR is just the only racing where that happens regularly and they try to mitigate it to extent they easily can now.

In most fast cars, the bottom is also part of that downforce generation with specific shaping.
But that shaping only works when going forwards.

I vaguely remember an organisation limiting the engines for safety.

charred relic
#

Well at some point the tracks won't be able to contain it

#

But hey why not find out just how fast you can go through turn 1 eh

night girder
#

NASCAR engines are limited to 358 cubic inches (5.86 liters) of displacement. These power units maintain a traditional V8 configuration with an iron block, emphasizing durability and power. The engines produce a target horsepower (HP) of up to 670 HP. Teams must adhere to these specifications, ensuring that the V8 engines maintain a balance between power output and reliability, with no team allowed to exceed these limits to maintain a level playing field.

#

In the Cup Series, NASCAR has historically employed restrictor plates to limit engine power for safety reasons. These plates restrict airflow to the engine, cutting its power and, consequently, reducing the speed of the cars on the racetrack. More recently, NASCAR introduced a system involving tapered spacers, which serve a similar purpose to restrictor plates but allow for more precise control over the engine’s horsepower and torque.

#

It was the restrictor plates. I heard about it in a documentary.

twin dew
#

Basically those fins are about giving extra air resistance when going sideways, but don't affect much when going straight.
So when you start going sideways, they both slow you down, and try to turn the car back forwards (or when gone too far, to go backwards.
And the pop-up spoiler is to slow you down via air resistance when not going forwards.

charred relic

Yeah I remember hearing about the plates

And we have moonshiners to thank...

Would it be stupid of me, to put proxies etc straight on my Synology in containers?

#

I know Herg recommended to me, to put it on a PI5 (and then I started to look into mini computers etc).

#

But now I am questioning myself again, if that is smart 🤔

twin dew
#

Usually would be fine.
In theory raises the attack surface onto the Synology a little, from inside the LAN.
But usually it would be perfectly open already from inside the LAN.

And in the very remote case that there is some kind of "external" exploit, it would still require someone from inside the LAN, to try to access some site where that attack is deployed from, via that proxy.

#

Basically IMHO that little extra security wouldn't be worth the cost in work, electricity, etc. for home network.

night girder
#

That was a worry of mine, that if they break out of the container, they are straight into my nas. If they break outside a container on seperate device, they still have to navigate my network. And depending on how I set that up, I can add extra security?

twin dew
#

But point is, how can someone attack (reverse-)proxy server program.

#

Either they need to already be in your LAN.
Or there must be some very weird exploit in the proxy server software and someone from inside the LAN needs to visit site which then attacks using that exploit.

night girder
#

Or docker container?

#

containers still are an attack vector.

twin dew
#

No it isn't.
As you need to first get into that container.
And if the only program that is network aware inside that container is the proxy software, how do you get in?

#

Unless you deploy container image with backdoor in it.

night girder
#

Docker is vulnerable.

#

If you think its 100% secure, then you are wrong.

twin dew
#

The ones I have seen have been in the Docker web management interface(s).
Usually in extension interfaces or extensions.

night girder
#

The container is open somehow, else it can't communicate with outside. Container (has open port)-> Synology (has open port) -> LAN -> Internet.

#

Or you close the port on synology, then it's fixed.

twin dew
#

"could be abused by a malicious extension in Docker Desktop"
Etc.

Point is that you need to secure the management of that Docker.
And I would expect that by default to be via Synologys management interface.

#

With optional remote access direct, which should be disabled in most cases anyways.

night girder
#

Sadly, yes 😦

#

No, remote access.

#

Well, I can enable remote access. Or I can install portainer agent on synology and control it from another device. But I didn't do that.

twin dew
#

And those direct Docker remote access services should be blocked/disabled in that Synology, so that the management is only via that Synology management interface.

#

Same as with any such tech, the expectation is that the remote management is in separate management-only-network that is very protected from anything else.

night girder
twin dew
#

Synology OS has software firewall in it.

night girder
#

yeah, I know

#

but it has no rules.

twin dew
#

Yes?
Because by default they are meant to be plug and forget devices where the access is only from same LAN.

Point it is that it would be trivial to configure that to block everything but its own management interface and file sharing.
And even limit access to that own management interface to only specific MAC and/or IP as source.

night girder
#

Mhm, then why do so many people set it up seperate?

#

And I mean, seperate devices.

twin dew
#

Because NASes etc. aren't actually that common?
And there are lot of instructions on how to do stuff with Pis for things like that, but not so much for other ways to do them.

I personally don't understand the point of (reverse-)proxy at all in home use.
There are other ways to do most of that stuff, and MITMing HTTPS to do checking on that is bad idea for most cases, as you then lose ability to check the certificates etc. on your actual computer, as everything will be signed by your own self-generated cert instead.

#

So for anything not SSL encrypted, there are better ways.
And for SSL encrypted things, you must MITM all that traffic intentionally, if you want more than IP.

night girder
#

Reverse proxy protects your app when you open it up to the internet?

twin dew
night girder
#

I mean, just google around.

charred relic
#

No need for self signed these days, letsencrypt is a thing

twin dew
#

That is for servers.
Having reverse-proxy before the server.

twin dew
night girder
#

Oh, so a NAS isn't a server? 🤔

#

Afaik, a NAS is just a server. If I want to put a app on it, and open it up to the internet, a reverse porxy is recommended.

#

This is the video that started my interest in this topic.

twin dew
night girder
#

It's not 1 thing you implement. It's firewall + proxies + ...

#

proxy is open for the internet, everything behind it should be hidden.

#

"And how to protect rest of your home network if the computer hosting internet accessible services has been hacked."

That's why I asked about seperate device.

twin dew
#

And anything that gets passed through that proxy will still hit that actual service program as is.
If there wasn't some protocol analysis level protection noticing known attack and not passing the data.

But like I said, I need to see what is the idea in that video.

#

Because so far the video has ignored the actual NAT-router-firewall in the center of the various images.
And this has almost exclusively talked about home hosting HTTP(S) server.
Not any other kind of server so far.
Just hasn't explicitly said it.

Also, treafik I am going to use for crowdsec. I forgot.

Which is again purely for HTTP(S).

Ok, it does support UDP, but the TCP and UDP stuff seems to just be about load balancing etc.

night girder
#

yup

twin dew
#

If you have multiple servers handling same thing in parallel.

#

So were you planning on hosting WWW-pages from your home network to public internet?

#

I understood you were only planning to host VPN from public source.

#

And everything else was to need that VPN to access.

night girder
#

vpn into an app for personal use (from outside my LAN)

twin dew
#

Or to be in the LAN.

night girder
#

That's my start. (or end-goal as a start)

#

Might give more access down the road. But first thing to do, is make a wall around my LAN. Then build in a gate, with a good gatekeeper. In the beginning, the gatekeeper will only allow me in (VPN).

#

crowdsec is just to get rid of all the bots probing 😄

twin dew
#

Basically the only relevant things on that specific video, if not doing public HTTP(S) server from your home, was that splitting the LAN into multiple ones, for different purposes and security levels, is good idea.
And that having some kind of IDS/IPS is good.
Where that IDS/IPS can be for example that Traefik with Crowdsec, for the specific types of traffic that combination supports.
Which isn't most types.

#

And that splitting into multiple happens on suitable NAT-router with firewall.
Most consumer ones cannot do that, as they only support single internal network for most part, outside of more limited guest-WLAN SSID.

#

Everything else was specific to HTTP(S) hosting from home to full public use.

#

In that video, the reverse-proxies were there to make port forwarding rules more specific, and to move authentication and monitoring stuff from the actual servers to separate device for management and performance reasons.

#

Where using cloudflare removes lot of that known bad traffic already so it never hits your own connection and overloads that.

night girder
#

How does this communication work? VPN on device 1 = ? protocol ? = VPN on device 2

twin dew
#

And then that local reverse proxy was more for that management side and more granular traffic monitoring like that crowdsec addon etc.

night girder
#

How does a VPN communicate to other device to **create **tunnel?

twin dew
night girder
#

Because you mention "HTTP(S)", I don't see that as a bad thing to secure?

#

So https?

twin dew
#

Without having to use VPN to get inside the LAN first.

#

And for that kind of limited service availibility, the attacker would first need to attack that VPN server software to get into the machine running that VPN server software, or to connect as VPN client.

#

And any crowdsec or like solution would need to be deployed on that NAT-router, or the VPN server.
Or as some other monitoring solution in the "pipe" that sees that traffic.

night girder
#

It will all be on one device, or that was my question earlier.

twin dew
#

Best would be on that VPN server, as that will then see both the VPN traffic coming in, and the actual traffic going out of that VPN server.

#

To rest of the LAN.

#

Or would need to be transparent separate device between VPN server and rest of LAN(s).

#

Which is why in my case IDS is living on the main NAT-router, and I have multiple LANs where any traffic between the LANs needs to pass through that same NAT-router.

night girder
#

And that's why I asked about VLAN a few days ago

twin dew
#

But for that VLANs are just implementation detail.
Point is to design the arch, and then convert it into VLANs before physical implementation.

night girder
#

First, it's technical possible to all throw this in containers on one device right?

twin dew
#

Basically just means that instead of multiple LAN-ports and multiple cables and multiple switches, you can use one LAN-port and one cable and one switch.

night girder
#

[DEVICE 1 >> DOCKER-CONTAINERS: vpn -> treafik -> crowdsec -> app?]

twin dew
#

You don't really have "apps" in this case.

For "best" security for this, you would want:
NAT-Router-Firewall with multiple LAN/VLAN support.
VPN-Server.
NAS.
Rest of LAN.

Where that VPN-server could in theory live on the NAS as container, but would probably best for it to live in DMZ zone, and NAS & rest of LAN in LAN zone.
With IDS/IPS of some sort on that NAS-Router-Firewall and limited traffic what that VPN-server can send towards the NAS, and none to rest of the LAN.

#

In theory that VPN-server could also live on that NAT-Router-Firewall instead too, as container or virtual machine.

night girder
#

I do have an app in this case? That's the one I want to get access too.

#

It's the whole point of this setup.

#

Having an app in a docker container, being accessible from outside my LAN.

#

With security.

twin dew
#

And you expect someone to break into that VPN, and then access that app.
And then to have reverse-proxy to protect against that?
Instead of just more generic IDS/IPS solution instead?

night girder
#

and again

#

reverse proxy doesn't protect me. reverse proxy + crowdsec does.

twin dew
#

Which might include Crowdsec in the mix.

#

So that ANY traffic from that compromized VPN-server, or even trying to compromize that VPN-server, gets included in the checked traffic.

night girder
#

Mhm. Good point.

night girder
twin dew
night girder
#

[proxy + crowdsec] filters out unwanted traffic, rest of traffic goes to VPN.

#

Oh right ...

twin dew
#

So basically only IP based filtering based on source address would work at that point.

#

Which can be already done with almost any good software firewall solution or any other IDS/IPS solution.

night girder
#

Well it would still protect VPN a bit.

#

security is adding layers.

#

not just one layer.

#

So I was thinking, the more layers, the better 🙂

#

And don't forget, I do this as a hobby. To learn.

twin dew
#

Which was the point on doing that IDS/IPS on that NAT-Router-Firewall.
Which would be in front of all other devices.
And if that VPN-server is then split into its own (V)LAN, where the traffic has to pass through that NAT-Router-Firewall before hitting rest of the LAN, then you get also monitoring of the decrypted traffic.

night girder
#

But I don't want to use my ISP firewall. It's crap UI.

twin dew
charred relic
#

Watching Gaming Historian makes me feel old AF

twin dew
#

Would need to set that ISP device to Bridge mode if possible, or to do double-NAT or like.

night girder
#

Sorry

twin dew
#

With second router behind that ISP device.

night girder
#

I mean, I don't want to use firewall on ISP router.

#

So you are suggesting. Don't do treafik + crowdsec (free). Buy second router and put firewall on it?

twin dew
#

Point was that that reverse-proxy part you are stuck in is mostly just HTTP(S) thing.
And the generic solution you are looking is that Intrusion Detection System (only warns that traffic happened) or Intrusion Protection System (blocks the traffic in real time)

twin dew
night girder
#

Ah, that I can do.

charred relic
#

A lot of folks buy off lease office small form desktops and shit for that oo

twin dew
#

ISP router in bridge mode, goes to switch as one VLAN that only connects to that actual router.
And comes out same port (or different port if the device has at least 2 LAN ports), goes to switch as another VLAN
And that second VLAN is what other devices use.

charred relic
#

depends on what size you want and how much of a deal you need

#

shit even the rack stuff is pretty cheap

twin dew
#

Or have two separate devices, one as that NAT-Router-firewall.
Second as VPN-server.
Where there is third (V)LAN where that VPN-server device lives on.

night girder
#

Can find second hand for 50 euro.

#

then some memory for 18 euro and I got 16gb for 70 euros.

twin dew
#

So VPN traffic comes from internet.
Passes through ISP router.
Goes to actual router.
Gets firewalled and if passes, goes through IDS/IPS.
Gets forwarded to VPN-server.
Gets inspected by VPN-servers firewall.
Gets unencrypted.
Gets inspected by VPN-servers firewall.
Gets sent back to the actual router.
Gets firewalled and if passes, goes through IDS/IPS.
Hits actual LAN.

night girder
twin dew
night girder
#

I can always later buy second device and seperate. But as a start, I don't want to swim in devices.

twin dew
#

With that virtual machine being most secure, and that specific device supported HW virtualization.

charred relic
#

I'm glad I don't have to spend too much brain power on this sort of stuff... the wonders of having a guy lol

#

It's not where you go it's who you know...

twin dew
#

Just "not as secure" as completely separate machine.
As if that VPN-service gets hacked, then if container or virtual machine, you can try to attack via those towards that base OS running the router and IDS/IPS.

But perfectly fine in reality.

night girder
twin dew
#

That was just about the "most secure" solution.
With that "run the VPN-server on the router" is the common solution and good enough.

charred relic
#

I think at some point to worry about more on that kind of connection you have to almost be planning to piss somebody off or something lol

Past a point somebody already has to put in work to get at you, they go for easy targets unless you specifically are being targeted

night girder
charred relic
#

Go to the next level and harden your linux installs 😄

night girder
#

arch linux needs hardening?

cobalt ivy
twin dew
# night girder So that would be the flow with MINI PC?

Yes, basically after ISP-router, but before NAS, it would be internal to that mini-PC.
With possibly virtual machine internal LAN in mix that VPN-service was running inside container or virtualization instead of the "main"/"hypervisor" OS.

charred relic
#

i dunno what arch installs by default

night girder
charred relic
#

typically it has to be installed intentionally as it's a whole... thing

#

your system will not function normally out of the box without work heh

twin dew
#

Crowdsec has Suricata log support for example.
Where Suricata is open source IDS or IPS solution with automatic rule updates etc.

night girder
charred relic
#

I was kidding... mostly. But if you really really did want to be secure that would be the path along with the networking stuff.

night girder
#

And that I should start with a good firewall.

charred relic
#

It sounds like you're already planning overkill for a home setup so... you should be fin elol

twin dew
night girder
twin dew
charred relic
#

Well having too much won't hurt... other than adding complexity

night girder
#

If you don't know what you are doing, I think you can really mess security up.

#

And actually enlarge the attack vector, instead of making it smaller 🤣

charred relic
#

plus you'll know how to do stuff if you need it in the future even if you don't NEED it now

night girder
#

That's why I am thinking about it for a few weeks now. And not just implementing it and see what happens.

charred relic
#

start small and expand on that

#

if you start with a million new things it'll be way way harder to know wtf went wrong

twin dew
#

Basically my own solution is that NAT-router-firewall-IDS (to be converted into IPS later).
With very secured access to and only accessible service being SSH with certificate from LAN side with additional limitations.

Then DMZ with single physical server, with very secured hypervisor OS, and then services in multiple virtualized machines.
And separata LAN.
(also IOT network for single IP camera that I don't want neither DMZ or LAN have general access to).

#

With each virtual machine OS with very restrictive firewalls, so that you cannot attack between them easily via network side, only by compromising the hypervisor somehow.

charred relic
#

oh wow Grsecurity went commercial at some point

night girder
#

ssh... wow. Oh SSH only inside lan?

charred relic
#

I have a machine that is maintained entirely via SSH

#

if it had a display i'd have a damn hard time seeing it from here too...

cobalt ivy
twin dew
charred relic
#

I mean... I could remote desktop but by

charred relic
#

pretty sure the switch my buddy got for me is all CLI

twin dew
#

And DMZ doesn't have even that access to it.
Basically compromise DMZ machine, you still cannot easily attack that firewall machine.
It does expose DHCP and DNS to DMZ, but IIRC thats it.

#

Could in theory move those later to that server into another VM.

night girder
#

oh, I forgot. There will be a switch before the mini PC. Not sure if that adds another attack vector.

twin dew
#

In a way, if that mini-PC only has single LAN port.
You basically need to configure that switch to not give management access over the VLAN that is for the WAN side.
And trust that there isn't some exploit that goes around that.

#

In the switch firmware itself.

#

Or just add second LAN port with USB or PCIe/m.2 adapter to that mini-PC.

night girder
#

That's why I asked about how many LAN ports me device should have.

#

because it would be switch -> mini PC -> rest of LAN.

#

and I though we can fix this with the VLANs.

twin dew
#

VLANs allow the router to not need multiple ports.
But if the WAN is also via the switch, then in theory the switch is internet accessible, if configured wrong or if that management access restriction side has exploits.

#

Separate WAN, and separate LAN side ports on router are better for that reason.
But nominally not needed with VLAN capable switch.

#

I'm not aware of any case where there was such vulnerability, but theoretically they can exist.

#

Just that getting kind of device you were looking for, with 2 LAN ports, is significantly more expensive than ones with just 1.

charred relic
twin dew
#

And USB-dongle will work in almost all cases as second port if needed.

charred relic
#

i just have to... get around to all that. He has a AP too. And a rack. And a rack UPS...

verbal raft
charred relic
#

Do I need a server closet. Well no but eventually I'll have one.

twin dew
charred relic
#

and PoE too which is perfect for phase 2

twin dew
#

So 1000/0, 500/500, 0/1000 as example theoretical splits.

night girder
#

"But if the WAN is also via the switch, then in theory the switch is internet accessible, if configured wrong or if that management access restriction side has exploits." what do you mean by this?

twin dew
#

Moment.

night girder
#

All I see on my GS308T is VLAN. Nothing about WAN.

twin dew
night girder
#

Yes, but how is my switch WAN accessible?

#

If there is a router in front of it.

twin dew
#

Like I said, wait a moment.

night girder
#

Dynamic VLAN creation mode is disabled btw.

#

and what I've read, the GS308T don't have a WAN port either.

twin dew
#

First pic is how you do it with single switch, VLANs and only single port on that mini-PC router.
Second is without VLANs with at least two ports required on the mini-PC router.

In first pic that switch is internet connected for that VLAN 1, and if it accepts any kind of commands over that VLAN, it is theoretically internet-configurable.

twin dew
night girder
#

Ok, that firtst picture.

#

Is what got me all screwed up in my head a while back.

twin dew
#

This is why I said to first design without VLANs.

#

And then convert to using them.

night girder
#

That's what I want.

twin dew
#

That second pic is how the traffic moves in both cases.

verbal raft
night girder
#

Yeah, I understand now.

verbal raft
night girder
#

So the firewall, is "gatekeeping" VLAN 1 into VLAN 2.

#

Telling what traffic can go from on lan into another.

#

And all the attacker see, is (v)LAN 1.

twin dew
#

Just that if doing it with single port on Mini-PC, and managed switch with VLANs, there is VLAN with pure internet traffic connected to the switch.
So in theory that switch is internet-administrable, if the config was done wrong or if there is firmware bug allowing going around that configuration.
Basic way is that you just set that "only this VLAN number can access management".

night girder
#

and the rest of my devices are safe on (V)LAN 2?

night girder
twin dew
night girder
#

No, I mean right now. How I am using it.

#

Router -> WAN -> Switch -> LAN

#

So, isn't my switch already "internet-administrable"

#

regardless of the VLAN etcs.

twin dew
# night girder But isn't that the case already right now?

Switch configuration detail.
Currently you have single VLAN on it, with ID 1.
Which all ports are "natively" connected to, and which the management interface is accessible over.

And to change to that kind of VLAN config, you would create two new VLANs in it.
Configure one port to only work as WAN VLAN port with no VLAN tags allowed and connect that to the ISP router.
Then configure another port to allow VLAN tagged traffic with WAN and LAN tags and connect that to the mini-PC router.
And configure rest of the ports only allow LAN VLAN traffic, with no VLAN tags allowed.

#

And configure that management interface to only allow access from LAN VLAN.

#

Not from default ID 1, or the ID you used for WAN side.

#

So without some firmware exploit, you can only then access its management interface from inside the LAN side.
Even when it is physically connected direct to internet, just ignoring anything happening on that side.

twin dew
night girder
twin dew
#

If it isn't in bridge-mode.

night girder
#

Internet -> ISP router -> WAN -> Switch.

#

Ah! Gotcha.

twin dew
night girder
#

So, Mini-PC router would be in bridge?

#

Or, no ISP router would be.

#

Yes, ISP router bridges traffic to Mini-PC router.

twin dew
#

Just to pass everything in both directions without doing anything above layer 2.
So not doing anything on IP level at all.

night girder
#

I don't think I can do this.

#

The LAN is a bit more complex than that. Not everything is behind the switch 😄

twin dew
#

Can also be done with ISP router still in full router mode.
But that just leads to need for double-NAT or like, and needing to configure any port forwardings on the ISP router too.

twin dew
night girder

ISP router goes to TV decorder.
