[tropic gyro]

no

[tame carbon]

this looks propietary af

[tropic gyro]

Web Browser

[desert briar]

Im honestly all HPE, have no experience with idrac

[peak cloak]

Yeah doesn't idrac have a utility?

[desert briar]

might wanna try what they are suggesting

get the client

[tropic gyro]

There are NO client

[desert briar]

just theoretically, you connecting to correct port?

[static knoll]

https://www.dell.com/support/kbdoc/en-id/000179517/dell-poweredge-how-to-configure-the-idrac-system-management-options-on-servers

Dunno if this helps

[desert briar]

some videos I see use 5900, some use 1266

[tropic gyro]

I will try this

[peak cloak]

@tropic gyro https://www.dell.com/community/PowerEdge-Hardware-General/T110-II-DRAC-Access/td-p/4171621

[desert briar]

So it might not be 80 or 443 by default

[static knoll]

https://cpsdocs.dellemc.com/bundle/XC_ISM_6515/page/GUID-B0435EAA-8B42-42BB-8D68-2ACF21182495.html

Maybe this

iDRAC utility lol

[tropic gyro]

Not working

[tame carbon]

run nmap

scan what ports its listening on

[tropic gyro]

A full scan is already runnning

I'll check if it's done

[desert briar]

hope it yields results

[tropic gyro]

76% done

[tropic gyro]

The iDRAC utility is a integrated tool, I have configured IP settings here

this is not a client

[desert briar]

does idrac have any firewall settings by any chance?

[tame carbon]

I say, bother dell support

this is their propietary stuff

[tropic gyro]

In some dell forum they say that some versions onf my server not have an iDRAC, BUT in my list of connected devices on my box's interface i have this :

(Freebox OS)

[tame carbon]

different versions have different implementation specifics

do you know what generation iDRAC this is?

[tropic gyro]

Where ?

[desert briar]

Im just asking, never worked with idrac

[tropic gyro]

I think it is an iDRAC 6

[tropic gyro]

Me too, this is the first time

[tame carbon]

https://www.dell.com/support/kbdoc/en-us/000123577/set-up-and-manage-idrac-6-lifecycle-controller-for-dell-poweredge-11g-servers#1

[desert briar]

I just know that i got an hpe g9 server some time ago and the ilo was broken 😦

[tame carbon]

https://i.imgur.com/Fv11A1s.png

[desert briar]

so i needed to refund it

[tropic gyro]

BUT it's already configured

but when I want to acces it from the browser it not work

[tame carbon]

did you configure it correctly?

[tropic gyro]

I think yes because it show on my freebox's connected devices list

[tame carbon]

yeah on layer 2 probably

but what about IP settings

[tropic gyro]

DHCP

[tame carbon]

idk then ¯_(ツ)_/¯

[tropic gyro]

So what can I do ?

[peak cloak]

@tropic gyro what did the nmap scan show

[tropic gyro]

I'll see if it's done

[desert briar]

all is closed

you sure idrac works / is connected properly?

might wanna scan your whole /24 for 80 and 443

or just set a static IP

[tropic gyro]

So I think the iDRAC is connected 😅

But still not accessible

[tame carbon]

you sure you got the right NIC?

[desert briar]

Might want to try r/homelab?

[tropic gyro]

There are only 1 network card

[tropic gyro]

What's that ?

[desert briar]

its a subreddit with a lot of people who like to have servers at home

😄

they have a discord server too I think, which I wont post here as I dont want to get banned. But if your issue wont get resolved you might wanna try to ask there

im afraid i cant help much more, as I said. My experience with dell devices is nonexistent 😦

[peak cloak]

Just search homelab in server discovery

[supple hare]

@tame carbon The store was closed, so here I am with my terrible connection again :/

Rn, for absolutely no reasons it works but I'm sure it'll stop working

[tame carbon]

didnt you unplug all those devices?

[supple hare]

I did, but rn they are all plugged in

It's always been like that, most of the time it doesn't work and sometimes it does

[split anvil]

Hey, I was told this is the chat where I can ask about a network dilemma I have?

Or should I ask it in tech-support

[tame carbon]

who told you that?

;)

[desert briar]

this channel is for real life networking as in getting to know others

[split anvil]

OH

[desert briar]

[split anvil]

OHMYGOD

im sorry

😂

[desert briar]

im just joking lol

ask away

[split anvil]

Well I'm kinda lost

[desert briar]

[split anvil]

Alrighty

[peak cloak]

Just ask your question@split anvil

[split anvil]

I have a TP Link LAN switch and I was trying to get both my PC and PS4 have ethernet since the router is in the living room, there are 2 cables in my room, one i definetely know it's for ethernet but the other is dubbed "kid's room" on a label slapped on the cable and I tried to connect that cable into the LAN switch and in the PS4 and I already have 1 cable that spreads into 2, one end for the switch and 1 for the PC, with my "knowledge" I know that a switch works when a LAN powered cable is inserted and it gives power to other LAN cables correct? If that's true, why when I go to my connection details it on my PS4 it says NAT-type unknown and it doesn't show any IP, or gateway or whatever?

It's a long one sorry hah

I have a screenshot of the ends of the cables and they are different

[desert briar]

might be an rj11

but yeah, please do send a pic

[split anvil]

one sec please

[desert briar]

that being said, if you plug in your playstation directly into the cable, do you get the "same" NAT mode?

or well, the other way around

plug your cable directly into your ps4 😄

[split anvil]

i know that the left one was used for a tv box or whatever and the right one is for my PC, i thought there wasn't any difference

[desert briar]

the cable on the right looks bad, termination wise

[split anvil]

When i plug the right cable in the ps4 there is the ip settings and whatever

[desert briar]

its not properly crimped, I assume?

[peak cloak]

Oh yeah that's not a normal cable

[split anvil]

i don't know what my ISP used but

[peak cloak]

@desert briar on the right one it's only 2 pairs

[tame carbon]

@split anvil your ISP did a shit job, is what that is

[split anvil]

the left one doesn't give any signal

[peak cloak]

@split anvil those are 2 different cables?

[tame carbon]

they used 4 pairs instead of 8

[desert briar]

left one should give a signal

[split anvil]

when i plug it in the PC it shows an orange light that blinks

[tame carbon]

@split anvil do you know where the other side of this cable is?

[split anvil]

alright so

the right cable is

split in 2

per say

[peak cloak]

Oh

[tame carbon]

yeah

[split anvil]

one end is in the switch

one in the pc

and they are directly connected as one cable in the router in the living room

[tame carbon]

what a nasty way to do networking lol

[peak cloak]

Yeah

[split anvil]

we don't really have smart people here tbh

[peak cloak]

2 100baseT over 1 cat5e wire?

Right

[split anvil]

ughhhhh

Yeah they did the wiring like years and years ago

[tame carbon]

@split anvil reterminate the cable properly on both ends, and then put a proper switch in front of it

[peak cloak]

Yeah

[desert briar]

Or well, pay someone to do it

you can learn it, but you still need to buy the equipment 😄

[split anvil]

I was thinking if like if i buy a new cable it would work? 😂

[peak cloak]

Is the cable in the wall?

[desert briar]

sure, but do u wanna drag it across the house? hah

through the walls

[tame carbon]

@split anvil you just cut off whatever they put on, and then put new headers on them

[split anvil]

UGH

[peak cloak]

It's not hard if you already have equipment

[split anvil]

I don't

[peak cloak]

But if you know someone who has

[desert briar]

Well, is the cable in the wall?

[split anvil]

Nope

[peak cloak]

It's an easy job

[split anvil]

It's stapled on the outside

here

[desert briar]

I guess the cable had some specific use some time ago

[split anvil]

it still has use

it's legit the cable that goes from the router to my pc

[desert briar]

what is it used for? Hopefully not internet

[peak cloak]

I guess you can get a new one

[desert briar]

[tame carbon]

@split anvil just reterminate the cable

and get a small switch

router <--> switch <--> pc, and other devices

[desert briar]

Yeah well, or just get a new long cable and replace this one. Its easier said than done

[split anvil]

What if i

[desert briar]

"reterminate it"

[split anvil]

Hmm let me try something

I'll use the end that goes from the router to my pc and connect it to the switch instead

and then the other split end i connect to the pc

wouldn't that technically work?

[tame carbon]

if you can use one of the 'two' links they have there

yeah, you could use a small switch

[desert briar]

You can try, but at this point I have no idea which end is which 😄

[split anvil]

lemme actually show you what i mean by 2

[desert briar]

im gonna shower, will leave it on you crystal

goodluck

[tame carbon]

@split anvil I understand what they did

[tame carbon]

you can do networking with 100mbit/s with only 2 pairs (4 wires)

you need 4 pairs to do full gigabit

so you can cut it up, and run 2x 100M

[split anvil]

We pay for 75 mb

[tame carbon]

@split anvil yeah thats internet

but I'm talking about the cable and the physical connection

[split anvil]

I see

Lemme try what i think could work

[tame carbon]

you need one of these ^

[split anvil]

I have this

Not that in the picture you sent

I meqn

[tame carbon]

yeah, you only need 1 connection between your router and your switch

[tame carbon]

there's only 1 thing plugged in there?

[split anvil]

Oh dont mind that

Thats for removal

Its not used

[tame carbon]

yeah, well isnt that a switch then?

[split anvil]

Yes

But i think i wired it wrong

[tame carbon]

@split anvil you connect both the router and the other devices to it

its just a bridge

so it bridges devices together on the same network

[split anvil]

YO

i got it to work

so the other end in the split cable

is basically

dead

or like it doesn't do shit

[tame carbon]

is that 2 jacks on 1 cable end?

and one has 8wires, the other only 4?

[split anvil]

yeah..

no

[tame carbon]

both have 4?

[split anvil]

i think its

4 and 4

yeah

[tame carbon]

if one of them is dead

its probably why they did this in the first place

[split anvil]

no like

when i connect it to the ethernet port on my pc

it blinks orange

just like when i plug the other cable that has internet running through it

i can't really explain adequately

so basically

i need another lan cable

[tame carbon]

yeah

[split anvil]

to connect to the switch

and then from the switch to the ps4

[split anvil]

ba da bing ba da boom

yeah something like that

[tame carbon]

I have one of those under my desk too

[split anvil]

although my placement looks like a fire hazard

[tame carbon]

?

[split anvil]

cable management is wack i mean

all around the place

[tame carbon]

lol you have no idea

how much gear is here

there's a lot of cables here

when I create a test setup

[split anvil]

im gonna ask if we have a free lan cable laying around because the other one is lon enough to run from my room to the kitchen

they legit

wired it

so that it goes from the living room to my room and from my room to the kitchen

[tame carbon]

they should have just used a switch

[split anvil]

through the switch

[tame carbon]

instead of cutting up the cable

[split anvil]

idk

they did it so meh

[tame carbon]

@split anvil yeah its the cheap and poor option

its just..

stupid really

because with vlans you can logically seperate the network into 4095 different networks

xD

[clear igloo]

16-ish million with VxLAN 😄

[tame carbon]

QinQ

@split anvil a switch is like 20 bucks, not sure why they cheaped out

If I did this at work, I'd probably be fired

though I've seen it before xD

@clear igloo lol Poor man's vlan

[hollow marlin]

Whats more important is you are removing L2 as much as possible, just as it was meant to be

[clear igloo]

Yup

[hollow marlin]

@clear igloo Also spent a few hours labbing this PM-4-ERR_DISABLE: channel-misconfig (STP) error which happened last week. God, all the stars had to align for it to happen

[desert briar]

STP, sounds familiar

orange blinking of doom

[hollow marlin]

Needed an RFO as it caused and outage for about ~1000 customers.

[clear igloo]

Yuck, that does not sound like a fun issue

[split anvil]

Jesus that was a pain

But we managed to get the cable out of the wall

since it was legit

stapled to it

[hollow marlin]

@clear igloo Yep, asymmetrical switching due to hashing and a rouge BPDU that somehow looped/leaked via customer equipment

[split anvil]

and got everything up and running, otherwise the whole switch was sitting there unused @tame carbon @desert briar thanks for your input on my problemo 😄

[desert briar]

thank crystal mainly, but goodjob man

glad you got it solved

[tame carbon]

@desert briar I've seen this trick with old telephone wires too xD

its usually 1 loop around the entire house

and what you do, is you basically cut off the middle, terminate both ends

and put a switch inbetween

that way you can just have a ring

it was basically 1 phone wire that went to every outlet in the house

[oak night]

Best 10 gig Switch?

[peak cloak]

I think everyone reccomends the 4x10G 1x1G mikrotik one

[oak night]

https://www.amazon.it/Mikrotik-CRS312-4C-8XG-RM-MikroTik/dp/B07VS1XJZ6/ref=sr_1_2?__mk_it_IT=ÅMÅŽÕÑ&dchild=1&keywords=mikrotik+10g&qid=1612644899&sr=8-2

What about this

?

[peak cloak]

that's only 10G on the sfp+ ports

not copper

[oak night]

Ah

[peak cloak]

@oak night

https://mikrotik.com/product/crs305_1g_4s_in

this one

[oak night]

Ok but one for use in rack?

[peak cloak]

oh like a bigger one

[oak night]

Yes with more port

[peak cloak]

there's this one

https://mikrotik.com/product/crs317_1g_16s_rm#fndtn-gallery

but tbh tht's way overkill

[oak night]

Oh ok

BUt it has Sft+

Fiber

[thorny vector]

@oak night Well, what features do you need?

[oak night]

Well 10 gig At least 12 ports and a good interface

and rack mountable

[thorny vector]

What do you mean by good interface? A good management interface? GUI or CLI?

[oak night]

Good management

interface

[thorny vector]

And what budget?

[oak night]

Well IDK

[clear igloo]

SFP+ can do copper too for 10g

[oak night]

Rj45

[clear igloo]

yes, there are copper and fiber SFP+ modules

[oak night]

With rj45?

[thorny vector]

Yes. Copper.

[oak night]

Ok can you send me some links?

[clear igloo]

https://www.amazon.com/10Gtek-SFP-10G-T-S-Compatible-10GBase-T-Transceiver/dp/B01KFBFL16

I'd suggest fs.com though

[oak night]

Ok

[thorny vector]

https://mikrotik.com/product/crs312_4c_8xg_rm

This ones not bad at 599

[clear igloo]

https://www.fs.com/products/74680.html?attribute=113&id=163923

They are usually cheaper than amazon but not in this case, lol

[oak night]

Wait so this one would be a good one?

[thorny vector]

Total of 12 ports, although 4 would need rj45 transcievers. and is a L3 switch

[oak night]

What that means?

L3

[thorny vector]

It means it can operate at both layer 2 and 3 of the OSI model

basically, means it can do routing too

[oak night]

Ok

[clear igloo]

Nope, you can use the SFP or copper ports

[thorny vector]

From the description "Combo ports can be used alongside the 8 regular 10G RJ45 Ethernet ports at all times"

[clear igloo]

and in that case no SFPs would be needed with that switch
Yes, they are SFP+ or 10G copper

There are 12 copper ports and 4 SFP+ ports, you can use the far right 4 copper or SFP+ ports but not both at the same time

[thorny vector]

I can't wait until I can justify 10g in my lab.

anyone here use ansible?

[desert briar]

🖐️

[thorny vector]

Never mind, got it taken care of

[desert briar]

Glad to hear!

[thorny vector]

finally getting around to automating a little of my administration

Speaking of which, if anyone on here hasn't updated any linux system you have in the past week or so... DO IT NOW.

[desert briar]

Referring to the sudo vuln?

[thorny vector]

yup

I just think about all the escalation I've had to do through binaries with bad permissions, or unprotected crons, etc... and it was just sitting there the whole time .

[desert briar]

Yeah, its pretty serious. Apparently affects MacOS too.

[thorny vector]

any and all things with sudo. going all the way back to 2011

think about all the embedded systems that will never be updated. All the servers that will never be updated. This is like eternalblue, but worse.

[desert briar]

Embedded systems which wont be updated have different issues

Like kernel exploits 😄

That being said, embedded systems often dont have sudo

Its just not packed in their barebones install

[thorny vector]

I'm not saying all of them will have it. But I know some do.

[desert briar]

Thats why you have utilities like busybox

[thorny vector]

Or stuff like a netgear router I keep around because its a great example device for embedded linux. Runs some linux kernel, can be accessed via default creds over ssh after sending it a debug command via http.

https://tenor.com/view/fuckyeah-yeah-ya-yes-yup-gif-5820940

[lean pebble]

BTW the moca is 2.0 but the tv reciver limited to 100mbps 😆

Just found out

[tame carbon]

@oak night how many ports you need?

CRS305 is nice because its an entry level 10G switch

and RJ45 10G is very expensive

transceivers cost a lot

I have that CRS305 at home, quite happy with it

[thick minnow]

Thats s sick setup

My Internet setup looks like a rats nest

[lean pebble]

Well crystal is hosting minecraft servers on his home network 🤪

[oak night]

Oh

[lean pebble]

He need good network gear

[thorny vector]

For minecraft?

[oak night]

Well i don't need it

[lean pebble]

@tame carbon am I right?

[tame carbon]

@thick minnow thats just the switch

[desert briar]

[lean pebble]

Only sfps

[tame carbon]

I dont host minecraft on this

[desert briar]

I doubt ya need 10gig to host MC, but iz a nice flex for sure

[thorny vector]

Minecraft is really low overhead

[oak night]

But i would love to have my own server for storage and for Apache and minecraft servers

[tame carbon]

minecraft needs like 2mbit/s per client

[thorny vector]

like, kb/s per connected host

[lean pebble]

😆

[thorny vector]

DO NOT run your own email server

[oak night]

Okl

[desert briar]

lol

I mean, run it. If you are a masochist

[oak night]

Eliminated

There is nothing

[thick minnow]

K I didnt

[tame carbon]

its a dossier of headache

[oak night]

[tame carbon]

self hosted email sucks

[desert briar]

and dont mind possibly miss-configurating 10 things at once

[tame carbon]

I use gapps for bussiness :D

[desert briar]

[thorny vector]

I set up my own email server, and got it all to work. But if it failed, I would not rebuild.

[tame carbon]

get to use my own domain, and still enjoy gmail's ease of use

[oak night]

I created one on a vps

And it worked

Mail server

[tame carbon]

microsoft has a habbit of blocking mailservers

for no good reason

[oak night]

Ok

[tame carbon]

and last thign you want

[lean pebble]

https://tenor.com/view/twho-hours-later-sp-funny-gif-18933136

[tame carbon]

is your email ending up in spam filters

[desert briar]

at the same time man, its a good practice. So 🙂

[oak night]

That's true

[tame carbon]

true

I still have to set one up

[desert briar]

learn from your mistakes and go for it

@oak night that's the router i posted in that image

I have that paired with that CRS305

has a single 10G port

https://mikrotik.com/product/rb4011igs_rm

that's a pretty solid router

[oak night]

Basically i want to create a home network cuz when my house was built no one thought about internet

[tame carbon]

10G is a bit over the top

[oak night]

I know

[tame carbon]

I use it because my NAS is faster than gigabit allows

[lean pebble]

I used to work in cloud hosting company and one customer always got blocked by our gapps

[oak night]

But I'd like to create my server

[tame carbon]

@oak night btw, I recommend going for fiber optics

its cheaper than copper

[oak night]

Serius

?

[tame carbon]

yeah

[lean pebble]

Ya

[tame carbon]

like, short distances ( less than 3 meters) you can do with a direct-attach cable

[lean pebble]

I wish I could have fiber at home

[tame carbon]

those are like 20 bucks

[oak night]

Ok but only short ones

[tame carbon]

but longer distances, fiber modules cost like 10bucks each

[thorny vector]

What kind of server are you trying to run?

[oak night]

At the moment

Nothing

[tame carbon]

those SFP+ 10G modules with singlemode fibers cost like 20 bucks

and fibers are

100 meters is like 30 bucks

[lean pebble]

5km?

[tame carbon]

LR,

so 10km

[lean pebble]

I think I need 2/3km for connecting it to the ISP infrastructure out doors

[tame carbon]

https://www.fs.com/de-en/products/111920.html?attribute=3892&id=176505

23 euros

[lean pebble]

I have 2

And 10gbps 2ports network card

[tame carbon]

and its just OS2 fibers

quite cheap

[desert briar]

Didnt know fiber is that cheap

[peak cloak]

Anyone know what this is

[tame carbon]

@desert briar I went the slightly more expensive route, but easier with cabling

BiDi interfaces, use two wavelengths on single fiber

they cost 30~ instead of 23

but you only need simplex fibers

https://cdn.discordapp.com/attachments/776722183119699988/777646103775674368/IMG-20200922-WA0001.jpg

as you can see here ^

there's only a single fiber, instead of two for RX/TX

[desert briar]

yeah, thats neato

[tame carbon]

its just 10G that is still affordable

[desert briar]

i have sfp+ transceivers where i just plug in rj45

[tame carbon]

once you go to 25G and up

[desert briar]

for 50 bucks each

[tame carbon]

it gets expensive

[desert briar]

ouchie

[lean pebble]

I just want the fiber internet

[desert briar]

Im waiting for a 40gbit NIC, ordered a QSFP+ cable as well

1 more week

[tame carbon]

@desert briar https://www.fs.com/de-en/products/111865.html?attribute=3895&id=176555

[oak night]

At least i'm upgrading to 1gig internet

[lean pebble]

Instead this shitty ADSL

[oak night]

With FTTH

[tame carbon]

these are the transceivers I have ^

@desert briar on the product page, look at the types

@desert briar there's one model, with RX/TX flipped

[desert briar]

pretty much the same price as the copper transceivers tbh

more range though

[tame carbon]

10km

[desert briar]

yeah, considerably more

[tame carbon]

and fiber is cheap compared to copper

like

the cable itself

[desert briar]

i mean i have so much cat6 i might as well use it

i have like 300 spare metres

[tame carbon]

cat6a is more expensive/meter than fiber

[desert briar]

because the house electrician kinda shot himself in the foot and got a lot more, lol

[oak night]

What do you think is better Cat6 or 6A for home networking and 10 gig

?

[desert briar]

its sexy

[tame carbon]

@oak night save yourself some headache and don't run 10G copper

[oak night]

Ok

[tame carbon]

its short distance cable and you need proper shielding or you get all kinds of interference

25 meters max I believe

[desert briar]

You will want to run some cables anyways, might as well go cat6a. Honestly, if you spend 80k on a house dragging cables for 50$ is negligible

[lean pebble]

I have this

[tame carbon]

@oak night SFP+ network cards are cheaper than their RJ45 10G counterparts

[desert briar]

+1 on that

[tame carbon]

that server I have in that image, just has a fiber going straight into the back

with an SFP+ module ofcourse

but you can just do that to a workstation :)

bend radius isnt terrible, as long as you dont jank on the cable

no problem running fiber to your desk

[lean pebble]

I have the network card but I can't connect it to my pc

I don't have enough space in my case for it my GPUs are too fat

[oak night]

That sucks

[lean pebble]

Ya I have it like 3 years

Bought it from eBay for 65$ including shipping

[oak night]

The problem with fiber is that it would have to go from my garage to my room and there are 3 floors between them

[desert briar]

get that drill boy

[lean pebble]

30meters?

[oak night]

I cant

[oak night]

Something like that

[lean pebble]

I moved one rj45 through the wall to my garden then to the basement

15/20 meters

[oak night]

I think that is too risky using fiber

[lean pebble]

Fiber ya

Maybe

[oak night]

That is why i would prefer to use copper

[lean pebble]

Well there is cat 8 for very long distances

[peak cloak]

Yeah you can't easily cut and put new connectors on fiber

[lean pebble]

And high speeds

But cost a fortune

[oak night]

I cant spend a lot

[lean pebble]

Cost even more that my network gear

😅

[tame carbon]

you can run fiber outside

as long as you put something around it

like a hard plastic tube

[oak night]

Ok but i cant pass it inside

[tame carbon]

fiber core is only like 9micrometers

[oak night]

It is concrete

[tame carbon]

the 2mm width of the plastic is mostly shielding

[oak night]

Found this

is this true?

[tame carbon]

cat7 is not even a recognized standard

[oak night]

Oh oK

[tame carbon]

like it exists

[lean pebble]

https://www.amazon.co.uk/KASIMO-Ethernet-Network-Internet-Connector-Black/dp/B07RKH3L41?ref_=d6k_applink_bb_marketplace

[tame carbon]

40G xD

[lean pebble]

Now it's cheaper

O_o

Ya 40G

[tame carbon]

@oak night fiber lines are much more reliable also

like, if you have a connection

they have 0 loss.

[oak night]

The only thing would be the pcie card for attaching it

[oak night]

I know

[tame carbon]

yeah

[lean pebble]

Can I make my switch Support 10gb?

🤔

[oak night]

That is hard cuz both have good PROs And both have bad Cons

[lean pebble]

I think cat8 is fiber under a mask 😷

[oak night]

Ahahah

It could be

[tame carbon]

once you accept that you wont be using rj45

SFP+ makes a lot more sense

[lean pebble]

I wish that will make me change all my network gear

[tame carbon]

I got one of these cards ^

[oak night]

Until i think that every device on my network has rj45

[lean pebble]

I have this

[tame carbon]

@lean pebble that card is more expensive than my router is

[lean pebble]

Haha

For sure man

Router costs 70$ shipping included or 250$ for enterprise equipment

I guess

This card can go from 500$ to 2.5k$ correct me if I'm wrong

@tame carbon

[tame carbon]

nah

its like 250 bucks

[thorny vector]

lol, a 10gbe sfp card?

[lean pebble]

Depends on the brand

[tame carbon]

2x 10G SFP+

but I specifically went with an intel card

[thorny vector]

https://www.ebay.com/itm/Intel-X520-DA2-10Gb-10Gbe-10-Gigabit-Network-Adapter-NIC-Dual-Port-E10G42BTDA/222736309597?hash=item33dc1e5d5d:g:l14AAOSwpP9Y8Xap

[tame carbon]

because I know those work properly with RDMA

[thorny vector]

90 bucks, and I know there are better deals.

[tame carbon]

and virtual machine handling

[lean pebble]

I have one to that Support 2x10G

[tame carbon]

@thorny vector I bought this card like 2 years ago, hard to find alternative offerings

I'd not get that card again

[lean pebble]

Do you want mine?

Came all the way from china

[lean pebble]

Lol

Crazy crystal

Crystal PC

[thorny vector]

I crossed 1 billion events not too long ago

[lean pebble]

This pic made me want to finish my full stack project

[thorny vector]

I regularly ingest over 10gb logs a day, with a peak of 26gb

[lean pebble]

Why

[oak night]

How fake

[thorny vector]

I log everything, on every system, then send everything to splunk

Windows event logs, active directory logs, syslogs from every linux host, application logs from every host

[lean pebble]

Are you a logging company?

[oak night]

It sure works

[tame carbon]

Hdmi to gardena xD

[lean pebble]

Lol wtf

Water over HDMI?

[oak night]

Wasn't it Hdmi over water

?

[lean pebble]

😂

Works both sides

Transferring water in high quality

High quality water

[oak night]

You can see everything in your pc

[lean pebble]

Ya

[oak night]

going underwater

[thorny vector]

Not a logging company, lol

Just my lab

[peak cloak]

Security?

[lean pebble]

Lol

[lean pebble]

So you basically log the log of the logs

[thorny vector]

Well, yeah

[lean pebble]

Why

[tame carbon]

you gotta be logging me

[lean pebble]

To much logs

[thorny vector]

To keep track of everything, monitor any errors, and for security

[lean pebble]

Log discord logs of isp logs and the log of steam logs

[peak cloak]

Log server, many enterprise things have options for a logging server. My eap225 has

[lean pebble]

He just logs everything not log server

[peak cloak]

Oh

[tame carbon]

https://i.imgur.com/fdKnWUZ.png

[peak cloak]

Packet logging?

That's a lot of data

[lean pebble]

26gb a day

How much does your lab have

[tame carbon]

cern has like a couple petabytes/day

[thorny vector]

@peak cloak Actually, for me its a logging cluster. 4 hosts that each ingest from other hosts, then replicate across each other. I log all of my network traffic, keeping the metadata forever, then keep full network captures for 14 days before roll over.

[tame carbon]

xD

[peak cloak]

Interesting

[thorny vector]

Right now my lab has 50+TB

@lean pebble

[lean pebble]

Gosh

Can I have some ?

[thorny vector]

I actually need more

[lean pebble]

Lol

I wanna get rid of my old HDDs

But I don't have nas server or something

[thorny vector]

I'll take em, lol. I have massive JBOD's of old disks, in raid/replicated zfs

[lean pebble]

Linus have even more

[tame carbon]

doubt it

[lean pebble]

All different sizes?

[thorny vector]

Yep. I have one server dedicated to the purpose of using mismatched disks

[lean pebble]

I mean his archive is greater than petabyte

[tame carbon]

The LHC experiments produce about 90 petabytes of data per year, and an additional 25 petabytes of data are produced per year for data from other (non-LHC) experiments at CERN. Archiving the vast quantities of data is an essential function at CERN. Magnetic tapes are used as the main long-term storage medium and data from the archive is continuously migrated to newer technology, higher density tapes.

[lean pebble]

Lol

[tame carbon]

@lean pebble 90 PB/year

[lean pebble]

I just want 20tb no more

[oak night]

Me too

[lean pebble]

For games , tv shows , anime, movies and backups

[oak night]

I have an hdd with 40 gigs of space

But it's useless

Cant use it anywhere

[lean pebble]

Storage:
M.2: 2TB Kingston
2 x 250GB SSDs for OSs
1 x 1TB Sandisk Ultra SSD
2 x 1TB HDD
1 x 2TB HDD
1 x 3TB HDD
That's what I have in my pc now

[oak night]

OH

[lean pebble]

I want to get rid of the HDDs

[oak night]

I have 1 ssd 480gigs and external HDDs

[tame carbon]

I could make a list of storage

but I dont really want to list my stack of 3.5" diskettes

[oak night]

one with 4 tb and the other with 1

[lean pebble]

Man this is only my regular pc

Not storage server or something

[oak night]

So you have more?

[lean pebble]

They moved with me from pc to pc

I have one more 2tb

[oak night]

That is my first pc so

I will carry them with the next one

[lean pebble]

Only the HDDs and the 2x250gb SSDs moved each time

[peak cloak]

what do you use to combine them together?

[lean pebble]

Well now it's 1x250gb I switched the one that runs linux on it to a new one

[peak cloak]

I have 3 older drives, 2 different sizes

2 x 2tb, 1 x 1tb

[tame carbon]

a piece of tape

[peak cloak]

zfs isn't good for that is it?

[lean pebble]

I have 6 of 300/600sas 2.5inch in raid on old server that offline

Because it makes alot of noise

[oak night]

What would be better for a nas in term of HDD

?

[tame carbon]

SAS

15K rpm

instead of 7200

[lean pebble]

SSDs

[oak night]

Also for Storing photos?

[tame carbon]

or NVMe

[lean pebble]

Honeybudger as nas

My dream

[oak night]

Cause i might have a Buffalo terastation

And would like to use it

Does it make any sense?

What i sad

?

[lean pebble]

For that only the two crazy doctors here can answer you

[thorny vector]

@peak cloak Something I wouldn't reccomend any one else use

[oak night]

Who?

[thorny vector]

BTRFS on windows

[lean pebble]

@tame carbon @thorny vector

😆

[thorny vector]

Those terastations are actually pretty nice

[tame carbon]

I use btrfs on my 2x 4TB raid1 array

[thorny vector]

but is it on windows?

[tame carbon]

debian

[thorny vector]

https://github.com/maharmstone/btrfs

This mad lad

[peak cloak]

why windows?

[oak night]

What does Btrfs mean?

[tame carbon]

@oak night its a filesystem

[peak cloak]

it's a file system

[oak night]

ok

[peak cloak]

more than a filesystem tbh

[tame carbon]

butter FS

btrfs

[thorny vector]

Because it was there. And I didn't want to do a lot of work. It's a temporary solution that became permanent

[oak night]

Do you know if i can use them as a webserver or for minecraft servers?

[peak cloak]

you can use anything for a webserver tbh

[tame carbon]

just install linux on it

[peak cloak]

mc on the other hand is a bit more intensive

[tame carbon]

and ur golden

[peak cloak]

depends on the cpu speed

mc is single threaded for the most part

[oak night]

Ok but does the default system allow me to create vm?

[tame carbon]

@oak night you can do virtual machines yeah, though there are more choices there

[thorny vector]

I wouldn't try to run anything like that on it. They're great for network storage, but their CPU's aren't great for serving any other kind of traffic

[tame carbon]

I use KVM for my virtual machines

but there are easier ways of doing it

[thorny vector]

Webserver would be okay, MC would not.

[oak night]

Ok

[tame carbon]

minecraft needs a lot of memory and CPU

[lean pebble]

I need a cheap air cooling for i7 4770

I need to the my old mboard and CPU

[thorny vector]

@tame carbon KVM? Plebian.

😛

[tame carbon]

@thorny vector I ditched vmware

[peak cloak]

212 evo

[tame carbon]

@oak night @oak night installing a webserver on ubuntu is as simple as running the command: apt install nginx

[oak night]

I know that

I've used ubuntu before

I was talking about the terastation Os

[lean pebble]

Thank you for saying nginx and not httpd

[tame carbon]

nginx is just the best one

[lean pebble]

Ik

[oak night]

I know that

[lean pebble]

Are you sure?

[oak night]

But for now i use IIS on windows

[tame carbon]

configuring IIS is torture

[oak night]

Srry everyone

[peak cloak]

I have that cooler

[oak night]

I did find it easy

[tame carbon]

I've used it before to run .NET ASP apps

@oak night yeah I don't like GUIs to configure my software

I just need a config file

and preferably one that isnt xml

[lean pebble]

I'll look into it

[oak night]

But i cant use PHP

And or similiar

[peak cloak]

xml, I hate it

[oak night]

My system and IDK why doesnt let me use it

[peak cloak]

nginx can't do php? it needs to pass it to another thing right?

[tame carbon]

I use nginx with php

[lean pebble]

My old nuctua got damaged on his way out

[tame carbon]

works fine

@peak cloak you can use fastcgi_pass

[oak night]

Fortunately i love both

[lean pebble]

You can connect it to php in other server too

[tame carbon]

yeah its a networked system

so your php instance can be elsewhere

[lean pebble]

I love it

[tame carbon]

same goes for ruby apps

with passenger

[lean pebble]

Easy to configure

[tame carbon]

https://en.wikipedia.org/wiki/Phusion_Passenger

[peak cloak]

I'm not familiar with php at all

[tame carbon]

This is for Ruby on Rails ^

[peak cloak]

or ruby

[lean pebble]

Never used ruby

[peak cloak]

what's so good about it?

[oak night]

Especially Https

[lean pebble]

Know to handle cache better and stabler

[tame carbon]

@peak cloak Procedural, Object oriented, functional

[lean pebble]

And know to handle the requests in much better way

I want to try the enterprise version of nginx sometime

[peak cloak]

for now I just use nodejs everything but may look at other things latter

so express webserver

not running anything big so whatever

[tame carbon]

The creator of Ruby at a conference said, he wanted a language that was easy to use like python

[lean pebble]

You can connect then to each other

[tame carbon]

but be a true OO language, instead of the weird ducktyping that python does

ruby is dynamically typed

but a lot of it is implicitly

its like a mix between java and python

[lean pebble]

I need to finish my Java project I don't know how to continue it 😆

[lean pebble]

Jython?

[tame carbon]

https://destroyallsoftware-talks.s3.amazonaws.com/wat.mp4?X-Amz-Algorithm=AWS4-HMAC-SHA256&X-Amz-Credential=AKIAIKRVCECXBC4ZGHIQ%2F20210206%2Fus-east-1%2Fs3%2Faws4_request&X-Amz-Date=20210206T235432Z&X-Amz-Expires=14400&X-Amz-SignedHeaders=host&X-Amz-Signature=4761cd7b90c57ed1064781138652b5cdf1bfd70b408841185738d6554881cf58

just watch this video

[lean pebble]

https://www.jython.org/

Never used it

[tame carbon]

there's lua, javascript, python and php interpreters for java

[lean pebble]

I hate php

[tame carbon]

it exists ¯_(ツ)_/¯

[lean pebble]

Ik

That's why I hate it

[tame carbon]

and if I need to whip something simple together

[lean pebble]

😆

[tame carbon]

I'd use php

[lean pebble]

I would use python

Or golang

[tame carbon]

with functional capabilities in java now

you can also write quick things

[lean pebble]

Like my project?

[tame carbon]

?

[lean pebble]

I'm stuck on generating stuff

[tame carbon]

wat

with maven or something?

[lean pebble]

Java

[tame carbon]

generating what

[lean pebble]

Some kind of lottery

[tame carbon]

source?

oh wat

[oak night]

I have to go Cya

[lean pebble]

I'll send you my code and the details of what I need to do

Cya man

[tame carbon]

@lean pebble you can just use Random

there's a JVM policy you can set, so the VM uses /dev/random instead of /dev/urandom

[lean pebble]

I did but I'm stuck in something else

Should I send it here or private or in development channel?

[tame carbon]

post a snippet here

nobody is using channel anyways

[lean pebble]

Lol

Here is the thing I'm trying to do with more accurate details.
Every two hours to conduct a lottery 10 different numbers in the range of 1-40.
Student writes randomly 6 arrays in size 7.
The values ​​in the array are also in the range of 1-40.
The student performs this for each lottery.
Winning:
If you can guess from the ten numbers 4 numbers or more.
Each win entitles you to a flight to the destination you want.
There are 10 students, with names.
Everyone participates in lotteries.
Indicate how many flights each has won
And who got the most flights
And this is the code I already have.
https://pastebin.com/1kGs6ZC9

[tame carbon]

you should start by introducing some datatypes

lie

like

this is already spaghetti.

unreadable

[lean pebble]

I'm stuck with the names / gets the winner / get each user 6 arrays of 7 numbers

[tame carbon]

and seperate your logic

https://i.imgur.com/KCgJV1Q.png

[lean pebble]

Ya ik I should choose better names that l / I /g

[tame carbon]

you're doing system IO

in the same functoin ,where you do calculations

you should create objects

to hold your data

and then give them methods

the scanner stuff

you should do in your main function

after that, you create a new instance of your Lotto class

[lean pebble]

Ya I changed it

[tame carbon]

and pass the information to the constructor

Java is very heavy OO

[lean pebble]

Can I get example

[tame carbon]

so if you don't use it

@lean pebble like

I can;t distill a logical data structure

[thorny vector]

Powershell is the true master language /s

[tame carbon]

package lotto;

public class Lotto {

    public Lotto(int parameter) {
        
    }
}

like, you can just create a parameter

put whatever information you have from the user input, and inside that class

you can then declare some fields

package lotto;

public class Lotto {

    public int foo;
  
    public Lotto(int parameter) {
        foo = parameter;
    }
}

for sake of simplicity

public fields

now, in your main class

you can do

    public static void main(String[] args) {
        Lotto myLotto = new Lotto(50);

        System.out.println(myLotto.foo);
    }

and you can then add calculations and such, either to the lotto object

or you create another object, and pass the lotto instance to it

@lean pebble methods should be concise in their naming and code

so more than 20-30 lines, you need a good reason.

lemme see some code here

where I wrote a simple program to do calculations for a runescape money making trick

yeah

main:

    public static void main(String[] args) {
        Scanner in = new Scanner(System.in);

        System.out.println("Calculator: (1) Perfect Juju Prayer, (2) Perfect Juju Fishing");
        System.out.print("Make your choice: ");
        System.out.flush();
        String choice = in.nextLine();
        System.out.print("Amount of herbs: ");
        System.out.flush();
        int herbs = Integer.parseInt(in.nextLine());

        if (choice.equals("1")) {
            calcPerfectJujuPrayer(true, true, herbs);
        }
        if (choice.equals("2")) {
            calcJujuFishing(true, true, herbs);
        }
    }

    private static void calcPerfectJujuPrayer(boolean well, boolean cleansing, int herbs) {
        GrandExchangeClient grandExchangeClient = new GrandExchangeClient();
        int potionPrice = grandExchangeClient.getItemPrice(Item.PERFECT_JUJU_PRAYER_3);
        int mossPrice = grandExchangeClient.getItemPrice(Item.HARMONY_MOSS);

        float output = calculatePotionOutput(herbs, 2, well, cleansing);
        float outputValue = potionPrice * output;
        int mossUsed = calculateMossUsage(output, well, cleansing);
        int mossValue = mossUsed * mossPrice;

        float profit = outputValue - mossValue;

        DecimalFormat df = new DecimalFormat("#.#");
        df.setRoundingMode(RoundingMode.HALF_UP);

        System.out.println("For " + herbs + " samaden herbs, the output would be: " + df.format(output) + " Perfect juju prayer potion (3)");
        System.out.println("GE Price (each): " + potionPrice + ", with a total value of: " + df.format(outputValue / K) + "k");
        System.out.println("Moss used: " + mossUsed + ", total cost of " + df.format(mossValue / K) + "k (" + mossPrice + " ea)");
        System.out.println("Profit per herb: " + df.format(profit / herbs / K) + "k");
        System.out.println("Profit total: " + df.format(profit / K) + "k");
    }

and the client itself was just simple rest & json

less than 70 lines

package me.crystal.runescape;

public enum Item {
    PERFECT_JUJU_PRAYER_3(32797),
    JUJU_FISHING_4(20019),
    PERFECT_JUJU_FISHING_4(35741),
    HARMONY_MOSS(32947)
    ;

    private final int id;

    Item(int id) {
        this.id = id;
    }

    public int getId() {
        return id;
    }
}

and all the items were just an enum

@lean pebble if you really structure your logic and your data seperately

makes for much easier time when developing

and also makes your code a lot more readable

[lean pebble]

https://github.com/InSelfControll/Algoritem-Studies/blob/master/firstjava/src/com/studies/semester.java

@tame carbon this is the updated one

Ya that's it

Ik but my teacher want all in one Java file

[tame carbon]

ew

[lean pebble]

Yap

[tame carbon]

who does that xD

@lean pebble you can make inner classes

[lean pebble]

My teacher

[tame carbon]

you can declare a class inside a class

[lean pebble]

That's sounds awful

[tame carbon]

if you want a single file

[lean pebble]

I'll go sleep now it's 2:25am here

[peak cloak]

I can't stay up that late

impossible

well I did once

[little schooner]

i did that yesterday and i got nightmares

[tame carbon]

wat

I stay up to like

3am every night

and sleep till like 10am

sunlight causes corona

[little schooner]

7hrs at least. good.

[tame carbon]

@little schooner though lack of sleep

I know what that is like

once a year at festival lol, 6 days

you sleep maybe couple hours a night

and partying itself is quite exhausting

after a week, lack of sleep makes you hear a beat in basically anything,

engine of a car

xD

I think longest I've been awake was like 40 hours or something

not good for your mental health though

[static knoll]

40 hours???? What would you do in 40 hours

Longest for me is 22

[little schooner]

partying

@waxen scroll what would network admins play at a lan party?

[static knoll]

probably something requiring infiltrating a network

and the first one to infiltrate/steal a piece of data would be rewarded

[tame carbon]

That sounds more like blackhat conference

[static knoll]

Ehh not if its a local network

Then it becomes greyhat/whitehat

[tame carbon]

Inb4 solitaire.exe

[static knoll]

Lol

If not, maybe try and prove that the wife is cheating (hacking into her whatsapp)

That could also be fun

[tame carbon]

When a programmer plays modded minecraft

[waxen scroll]

@tame carbon some kind of mmo, if they were a gamer at all

[tame carbon]

You end up with a fully computer controlled nuclear reactor

[waxen scroll]

Most of the ones I know dont game

[static knoll]

Nuclear reactors in modded minecraft are overrated, fluid cow energy 4EVA

[tame carbon]

Opemcomputers is cool

It behaves like a unix system

[waxen scroll]

I don't really game either. If I did, mmo

[static knoll]

MMO? Why specifically mmo

[tame carbon]

I like strategy and base building

[static knoll]

ah

Makes sense then

[tame carbon]

though, I also play Civilization quite often

If you like turn based strategy and boardgames, theres no better

[static knoll]

I don't like most MMOs because they get too grindy

Especially the free ones

[tame carbon]

One game in Civ takes like 6 hours to complete

[static knoll]

I don't have 6 hours to game, and by that point my poor i7-8565u would be dying

Little ol 15w 4 core

[tame carbon]

Well, its turn based strategy

So you can just save the game

[static knoll]

Regardless, the map alone would be a lot

I don't have a system with more than 4 cores and a base clock of 3.6

[tame carbon]

You can run it on a laptop

Its not that demanding

[static knoll]

Not an ultrabook

And especially not on a U processor

[tame carbon]

Game has two view modes

Either rendered 3d

Or strategic view

Which is 2d

[static knoll]

I mean, I could play it in 2d but it just doesn't have the same appeal

I like my sims to be highdef 3d

Otherwise, they're not very appealing

[tame carbon]

Trust me though, as long as you dont move the camera fps is good

[static knoll]

well obv lol

[tame carbon]

Ive played it on a 5500U with a GeForce 940M

2c4t 3Ghz

[static knoll]

What happens if you move the camera tho

[tame carbon]

Frames drop a bit

[static knoll]

To me, a game is only enjoyable if I can get at least a smooth 50fps

[tame carbon]

But you can reduce details

The thing is

You don't really need smooth frames for turn based stratgy

[static knoll]

Fair point

[tame carbon]

Anything above 20 fps is playable

[static knoll]

Regardless, Minecraft to me is more interesting

Open world is more my type of game

rather than turn based

[tame carbon]

Factorio is very lightweight

[static knoll]

Only turn based game i rlly enjoyed was fire emblem on the 3DS

[tame carbon]

You can have a million machines without drop in performance

[static knoll]

True

I need to do some stuff today tho, will see

Crypto money incoming lol

[tame carbon]

Minecraft is a killer for most laptops

[static knoll]

Modded MC

[tame carbon]

Since its still a demanding game

[static knoll]

Normal? Fast works fine

[tame carbon]

Yeah I only do modded
