@MathCubes uhm...

what are you actually trying to do?

uhm, usually no

Even if I've done worse

bwDraco

The cable's resistance is likely to be a problem. Devices at the end of the cable could see too low a voltage.

Journeyman Geek

or catch fire

@MathCubes you're almost certainly better off using different rails

bwDraco

If you do in fact need to do that, try to daisy-chain as close to the power supply as possible. The shorter the length of the cable run, the better.

Journeyman Geek

maybe use a modular power supply - they'd give you 6x sata I guess, then use molex to sata converters for more

bwDraco

Also, have you considered an actual SATA backplane device?

Journeyman Geek

1:09 AM

@bwDraco assuming they're not showhorning them into a normal case...

A modern PC has plenty (ludicious?) sata ports without a backplane

bwDraco

@JourneymanGeek I wouldn't consider eight (as is the case on Astaroth) to be ludicrous.

Journeyman Geek

I would!

So, in the old days, back when policemen wore long pants....

You'd have two IDE ports for 4 drives.

bwDraco

Of course.

Journeyman Geek

Most cases don't have space for more than 4-6 unless you got something like my old cosair 600T

On a modern build you'd likely run your OS on a M.2 (and new build motherboards have at least 2).

We don't really do optical drives any more

Its kinda sunsetting like floppy drives where its either an "in case" thing, or you buy some cheap USB drive, or happen to have one from a few PCs ago.

bwDraco

You have a point. Setups with more than two drives are uncommon these days.

Journeyman Geek

1:14 AM

I think the most I ran was 3 drives - OS, bulk storage and a drive for games

bwDraco

And folks who do need lots of drives are more likely to be using them with a NAS appliance rather than a desktop PC.

Bob

@JourneymanGeek /me looks at extra SAS card

Journeyman Geek

(there's probably a good/strange reason for having all those ports though - parts reuse)

bwDraco

(there's three internal drives on Astaroth, one M.2 and two SATA, all SSDs)

Journeyman Geek

@Bob Outlier though, and sas card is a sensible way to put in ludicious amounts of disks

On the other hand, I suspect that modern drive controllers support all those drives anyway (and shared blocks with servers)

and the cost of supporting them is marginal

Bob

1:16 AM

@JourneymanGeek I was actually preferring a SATA card but they don't make 'em like that

@JourneymanGeek Mostly the cost of routing traces through the mobo, IIRC

Journeyman Geek

@Bob actually I suspect that would cost about the same to make

and there's much more complicated things, like say PCIe

and then, board makers add more ports - my old asus had an additional onboard controller

Never really checked on this one

bwDraco

PCIe is expensive, and most applications that handle extremely large amounts of data (terabytes or more) only need SATA-level speeds.

Bob

@JourneymanGeek Yea, that's a selling point to some people (*cough*)

Though that was more in the days when the chipset didn't support as many

Or didn't support all SATA 3

@JourneymanGeek Well... I've seen mobos with 4 ports

heck, I've got a Dell box here with 3

bwDraco

Father's desktop supports only three SATA ports.

Bob

and a 4th spot on the board that's lacking the connector

not sure if it's routed

bwDraco

1:21 AM

And it's AMD B350 and not some ancient chipset.

Journeyman Geek

Ok, enthusiast boards have ludicious amounts of ports? ;p

Bob

lol

my enthusiast board only has 6 :(

bwDraco

The M.2 SSD only supports PCIe 2.0 (which I suspect is due to it hanging off the chipset).

Again, eight SATA ports on Astaroth (ASUS ROG Crosshair VI Extreme).

Bob

but then it went with more M.2 rather than more SATA, and a couple of them double as SATAe

And, well, SAS expansion. So yea.

In hindsight maybe I should've gotten the SAS card with 1+1 external/internal

Grab one of those HP storage boxes that supports like 24/48 HDDs...

Journeyman Geek

lol

dell has them too

and you could probably get them second hand

I haven't checked on this

Bob

1:24 AM

The problem is USB externals are much cheaper per TB

and I can't be arsed shucking them

bwDraco

The board has two M.2 slots; one of them is beneath a heatsink that goes on top of the southbridge heatsink and uses the Ryzen SSD lanes; the other shares bandwidth with the second PCIe slot (and would therefore reduce graphics card bandwidth to x8 if used).

rahuldottech

Looks like this week is going to be great for cycling

Journeyman Geek

My case would at most do 2 3.5 inch, and 1 5.25 inch (which could be converted to 2.5 inch bays in plural)

I'm likely going the dedicated, non ludicous NAS route in future

Bob

@JourneymanGeek Didn't you have a big-ish case?

bwDraco

The 760T can accept four 2.5-inch drives (7mm z-height) and six 3.5" drives.

Journeyman Geek

1:26 AM

@Bob downgraded from the 600T to a coolermaster dealie

I have the 600T still

Bob

think mine's 4x 2.5", 6x 3.5/2.5", 3x 5.25"

which is far more bays than I ~~have~~ had SATA ports

Journeyman Geek

Need to fire it up at some point, that's 8x 3.5 inch bays, 2x 5.25 inch bays

Bob

ah yea

good ol' huge corsair cases :D

you could chuck a cheapie board in it and turn it into a NAS

Journeyman Geek

I need to see if it runs, was freezing after boot, so mught run linux and some stress tests.

@Bob that's what I was looking at those chinese xeons for.

the lower end ones look fun for a home server/nas

Bob

I'm not really a fan of NASes though... 1GbE isn't quite enough and 10GbE is still expensive

bwDraco

1:27 AM

And three 5-1/4" bays (the top one of which may collide with a larger liquid cooler; planning to swap out the H100i v2 with a H115i RGB Platinum when I upgrade the CPU)

Journeyman Geek

@Bob if its short range/single PC, 10gbe DAS looked cheap

Bob

unless I end up actually needing the network access, I'd much rather USB

bwDraco

Yeah. Consider the Drobo 5c?

Bob

@JourneymanGeek What, extra cards for a direct link?

I suppose that could work...

bwDraco

(USB Type-C DAS appliance with five drive bays)

Bob

1:29 AM

Pity 10GbE switches cost so much

I think my cabling would support it

Journeyman Geek

@Bob ACTUALLY.....

Bob

@JourneymanGeek L5520s are cheap :D

dual L5520s are cheap :D

Journeyman Geek

amazon.com/MikroTik-Desktop-Gigabit-Ethernet-CRS305-1G-4S/dp/…

Bob

only problem is DDR2 isn't so cheap

Journeyman Geek

craft computing reviewed this

@Bob thats what I like about those chinese xeons

Bob

1:32 AM

@JourneymanGeek would need SFP modules :\

Journeyman Geek

@Bob or DAS cables

which seem pretty cheap

Bob

@JourneymanGeek DAS cable?

direct attach ment?

o.O

*dac

1:34 AM

kinda ruins the whole point of having a switch if you're limited to like 3m

Journeyman Geek

true

Bob

problem is 10GBASE-T costs >$80

maybe I should rewire the house with fibre...

OM3's pretty cheap

Journeyman Geek

lol

Bob

and 10GBASE-SR is like $25

Journeyman Geek

This is how it starts

Bob

1:35 AM

I'll blame you :P

Journeyman Geek

This folks, is why I should NEVER become a drug lord

bwDraco

lol

Bob

@JourneymanGeek so apparently the L5520 supports DDR3

LGA 1366 boards are $80 on eBay

Journeyman Geek

@Bob Thankfully, I don't have the space/time for now XD

Bob

A pair of L5520s is $20

what. why.

Michael Frank

1:45 AM

I've had some pretty nsfw AliExpress suggestions recently.

Journeyman Geek

.... its 6.90 on aliexpress.

@Bob still inclined towards the LGA 2011 setups

Bob

@JourneymanGeek It was $20 local shipped :P

AUD, mind

@JourneymanGeek A bit more modern? :P

Journeyman Geek

Yup

but

My old core i7 should probably still work

It kinda lagged a lot the last time I fired it up

but it costs me... nothing

Just need to find the time to reinstall the OS

Bob

lol

Q: Bridge two NICs

(I know next to nothing about networking, so bear with me.) I have a Linux board with two NICs. One will only be connected to another board, the other will connect to a network. I need to make the other board able to reach the network, likely broadcast UPD onto that network and have things conne...

you just need to... literally bridge the two interfaces right?

I recall doing this in windows before

> The first ones to lose access will be Windows XP and Windows ME users.

And someone in the comments goes "Don't you know how old XP systems are?"

ME systems are like... up to 18 or so years old

MathCubes

4:34 AM

@JourneymanGeek But you can get customs ones that long

ebay.com/itm/…

Here is one for 9

@bwDraco

Thoughts

bwDraco

Can't recommend it. The wiring on the SATA power connectors looks very flimsy.

MathCubes

K

rahuldottech

7:53 AM

@JourneymanGeek nah, XP is 18, as old as me. ME is older.

@MathCubes still kinda saddens me

djsmiley2k

9:12 AM

ME came after XP, before Vista

Didn't it?

oh god it's so long ago I don't remember.

Journeyman Geek

Yes

ME and 2K were at about the same time

djsmiley2k

yah, me meaning Millenium.

Journeyman Geek

Then XP was kind of merging the "home" and "pro" OSes into one

Bob

10:09 AM

I'm so confused

Why are people saying ME came later? o_O

ME was 2000, XP was 2002

Journeyman Geek

10:27 AM

@Bob old age and senility

The point I was trying to make was ME machines are so old... people didn't even comment on em

Bob

@JourneymanGeek Well yea, that describes ME and XP pretty well

Journeyman Geek

@Bob I wouldn't accuse XP of being senile

its that old goat who's about 200 and refusing to die due to sheer spite.

Actually also true of OS/2 I guess

._.

djsmiley2k

10:54 AM

ME, then XP, Then Vista?

fair enough, like i said, can't remmeber

rahuldottech

11:08 AM

XP was released to manufacturing on August 24, 2001, and broadly released for retail sale on October 25, 2001.

@JourneymanGeek technically '01. Little under four months younger than me.

Journeyman Geek

11:45 AM

@djsmiley2k well 2k and ME, XP then Vista

XP derived from 2k

Sam

1:53 PM

Hey guys, do you know how someone could hide their server IP secure and with as less resources as possibel?

possible**

e.g. someone types in stankmemes.com > it gets translated to VPN address > vpn forwards to my server IP

and my question is, is a vpn enough to do that? or is a proxy also good? or do i need both?

Journeyman Geek

@Sam you're looking at it wrong

Sam

Okay, go o

on

Journeyman Geek

You shouldn't really be using a VPN for that - and honestly that's the worst sort of cargo cult security by obscurity

djsmiley2k

wanna hide your server? cloudflare.

Journeyman Geek

You protect a server with sensible firewall rules

You stick it behind something like cloudflare for stuff like ddoses

You secure your ssh server by blocking root logins and using key based auth

And all these things are resource cheap

djsmiley2k

2:09 PM

@bwDraco a real job

arstechnica.com/staff/2019/07/…

go go go.

Seriously.

go.

Burgi

he won't

Sam

no i mean i want to hide the ip of the server so they cant trace the location

Burgi

you need TOR

djsmiley2k

lol good luck with that

'hiding' a server is nigh on impossible

because it has to be accessible

it's impossible, because you have knee caps, and want to keep them

Sam

knee caps?

djsmiley2k

2:12 PM

!!xkcd 538

Burgi

what possible use case have you got for obfusticating the IP?

Sam

and im not planning on using ssh at all

the same as wikileaks

only they are at bit wealthy lets say, they host in a nuclear bunker

so im hosting at home

djsmiley2k

that went so well for assange.

Sam

sadly

djsmiley2k

So you've just given up the physical location of your server, on a public chatroom

well done. you've already lost the game.

knee caps.

Sam

2:14 PM

oh that way okay

where do you see my IP address then?

djsmiley2k

I don't want, nor need to see your IP address

Sam

stack overflow doesnt store it does it?

Burgi

probably

Sam

now you got me acting paranoid damn

djsmiley2k

I'm always amazed this works

Sam

2:15 PM

na but its ok i left my vpn on

Burgi

they run Windows stack. IIS logs all access requests with the requesting IP

djsmiley2k

If I wanted to be really evil? I'd invite you to a room on your own, then link it.

Sam

yeah the ol' grabify trick.

djsmiley2k

grabify?

Sam

2:17 PM

or is that not what you ment

meant

djsmiley2k

i just used the fact that the chat, by auto, displays hotlinked images.

and I run that web server

Burgi

move your server to TOR

djsmiley2k

so when everyones clients hungrily grabs the image from the server, I see y'all.

Sam

oh okay thats kinda weird

djsmiley2k

Not really

Infomation security is hard.

Sam

2:18 PM

yes not weird i mean mean

mean mean haha 2 times in a row who wouldve thought

but anyway how to obfuscate an IP address?

Burgi

TOR!!!!

Tor (anonymity network)

Tor is free and open-source software for enabling anonymous communication. The name is derived from an acronym for the original software project name "The Onion Router". Tor directs Internet traffic through a free, worldwide, volunteer overlay network consisting of more than seven thousand relays to conceal a user's location and usage from anyone conducting network surveillance or traffic analysis. Using Tor makes it more difficult to trace Internet activity to the user: this includes "visits to Web sites, online posts, instant messages, and other communication forms". Tor's intended use is to...

Sam

yeah but only 0.1% of all people use tor or something

i cant access a .onion domain with chrome

Journeyman Geek

@Sam on a server? You don't

Sam

dont what

Journeyman Geek

Hide your ip

Sam

2:22 PM

@JourneymanGeek what about tor?

Journeyman Geek

It's like saying 'i want mail but I don't want anyone to have my address'

@Sam Tor is a privacy tool

Not a great way to actually do stuff in a performant way

Sam

i dont really care about performance

i care about not being tracable

Journeyman Geek

@Sam Don't run a server then.

Sam

aargghghggh

my only option is cyberbunker then but thats too expensive

Journeyman Geek

Cause literally people need to find you

Sam

2:26 PM

im a student not a mothertrucking CEO

Journeyman Geek

Language!

@Sam what's wrong with cloudflare?

Sam

theyre too expensive

Journeyman Geek

What's your threat model?

Sam

literally i have 0 dollars

Journeyman Geek

They have a free tier

Sam

2:27 PM

(as budget)

Journeyman Geek

Aws has a free tier

VPNs cost money

Sam

thread model as i really dont like the FSB to come to my house and bust my kneecaps

threat**

and i want as little third party as possibe

possible

Journeyman Geek

Ok... So... You might want to get familiar with the work of michens

Sam

Doubly so with no budget

Triply so with no third party stuff

Journeyman Geek

Yup.

Sam

2:34 PM

NSA/CIA in russia.

Burgi

not much you can do to defend against a Wrench 1.0

Sam

so lets say i have a little money to spend, would it be a good idea to use a vpn with port forwarding?

Journeyman Geek

Nope

Sam

why?

Journeyman Geek

Better to spend the money on cheap trustworthy hosting outside russia

Sam

2:35 PM

yes but russia has a lot of money and a lot of power.

Journeyman Geek

The VPN is unlikely to give you a public ip

Sam

they just say "cyka i want that server down" and it goes down

Burgi

you could try not doing anything that pisses off the russian government

Journeyman Geek

And here is the thing. If they want to get you, you're still a client of the VPN provider

Sam

@Burgi it doesnt nessicarily but it can and could

Journeyman Geek

2:37 PM

They can do it to your VPN provider too

Sam

okay ill explain

the main reason why i want my server at home is to configure it directly without ssh. i hate ssh. I also hate ftp.

i just want to walk to my server, say "good morning server" and eat my oatmeal

Journeyman Geek

Uhm

Sam

"oh looks like i got to change /somefolder/index.php oh look i can just turn on my screen and type!

Journeyman Geek

I can't imagine running a server without remote access

Sam

that kind of shizzle ykwim

Burgi

2:40 PM

@Sam i think you want a tree, not a server ;)

Journeyman Geek

So let's forget the stuff about the fsb

Practically lots of folks host at home

You just need an isp chill with it

And no ssh is fine

And... Dang. I'm not sure if cloudflare masks your ip

But it might

Sam

nah its just ddos protection afaik

blog.cloudflare.com/ddos-prevention-protecting-the-origin

Journeyman Geek

Hmm

When someone attempts to look up who hosts your domain, DNS will return an IP address in the CloudFlare network.

That sounds like it hides your ip

Canadian Luke

It does hide your IP. Requests coming in will get forwarded on, so they act like a large router that also supports caching

However, you can also use the DNS features to allow "direct" connections to your server(s). I do that just so I have SSH without having to memorize the IP addresses

Sam

kk, thanks guys

Ill speak to you in a month or so and say if i still have my kneekaps

@JourneymanGeek it does

you can't have ddos protection if your upstream ip address is exposed

I kinda wish there were more options for USB PD power banks that could output 45W or more and weren't outrageously priced.

(my laptop needs 45W to charge at a reasonable speed, and ideally 60W or more)

This did come in today: amazon.com/Anker-PowerIQ-Delivery-Charger-PowerPort/dp/…

Already have a 30W USB-C/19.5W PowerIQ/QC2.0 combination charger but wanted something smaller that I could just keep in my bag so I don't have to pack the former charger every time I leave the house. Only needed one high-output USB-C port, and faster charging is a boon when I'm in a hurry in the field.

Mostly older ones, put in high-performance USB 3.1 Gen 2 enclosures. One is an old 64 GB Plextor M5M, the other is a 500 GB Samsung SSD 850 EVO.

Also have a 512 GB Samsung SSD 850 PRO (also in a USB 3.1 Gen 2 enclosure) being used mainly for expansion and write offloading on my main laptop Stolas.

Anyhoo, got more SSDs than I actually have a use for.
