think of all the wives and kids CCIE holders neglect

tough bluff
#

Yes

subtle glen
#

dont think so

#

ah...

#

well..

clear igloo
#

No, I don't need to for my rack at home

rocky badge
#

@waxen scroll lol

tough bluff
#

All the power is controlled via managed IP systems

subtle glen
#

fffff

tough bluff
#

My office and the it office is miles away from the server room

subtle glen
#

is that place some sort of disneyland for network admins

tough bluff
#

It would be a inconvenience to drive back

rocky badge
#

Lol

gritty owl
#

That's pretty awesome

tough bluff
#

Not Disney land

#

Very industrial

#

Disneys worst nightmare

clear igloo
#

lol

rocky badge
#

Lol

waxen scroll
#

speaking of disney, half our department are disney fanatics

#

i go every year

rocky badge
#

Sounds like my friend

subtle glen
#

i have never been to disneyland

rocky badge
#

Excpet he doesn't work

tough bluff
#

I go every year but can't go on rides

rocky badge

#

BUT can you remotely turn on the breaker if the power goes out and get a notification UHH?

tough bluff
#

Yes

subtle glen
#

MMMM

tough bluff
#

All our breakers anywhere are smart

#

Even in the mills

#

Its crucial to production

subtle glen
#

my main breaker is one 50 yrs old with fuses

rocky badge
#

The s may stand for smart but probably not for secure kappa

waxen scroll
#

TBH fam, i wouldnt want a breaker turned on remotely... you need to ask "why did it trip?"

rocky badge
#

fam

subtle glen
#

that trips for overload

rocky badge
#

when old people use words like lit, fam, etc

tough bluff
#

We have a server that manages breakers and electrical

waxen scroll
#

right, if it overloaded you need to go on site and ask why

subtle glen
#

WTF, a server even for that????

tough bluff
#

I'll get a notification on my dash board if something goes off

subtle glen
#

too many appliances

tough bluff
#

Plantation

#

We have a steel mill

waxen scroll
#

@rocky badge thats lit AF

tough bluff
#

Wood mill

rocky badge
#

Ewwwww

tough bluff
#

Alot of other growing operations

clear igloo
#

fo shizzle dawg

rocky badge
#

You used the word lit

waxen scroll
#

my generation invented memes

clear igloo
#

the me me's

rocky badge
#

I don't care for memes

#

๐Ÿ˜„

tough bluff
#

Memes make me question every thing

gritty owl
#

Indeed. haha

waxen scroll
#

i called them "meh mes" for the longest time

tough bluff
#

We have a meme in my office and it bothers me so much

rocky badge
#

My friend spams DMs and my memes channel with memes everyday

#

Lol

subtle glen
#

@waxen scroll we also have this model that automatically turns the power on only n times you set it to. If you set it to like 3 attempts, and it re-enga ge itself 3 times in a short period of time, it wont turn the power on cause it knows theres something wrong

tough bluff
#

That's sketch

#

Ours dont auto turn on

subtle glen
#

AHHH

waxen scroll
#

whats the amperage of that thing

tough bluff
#

There just connected to a management system

subtle glen
#

lemme check

tough bluff
#

You need to send a message to get them to click on

gritty owl
#

yeah, I wouldn't want a breaker to auto turn on. haha

rocky badge
#

Yeah

gritty owl
#

Sees the sparks

#

lol

waxen scroll
#

that thing looks like it cant do past 200a

subtle glen
#

you can set it to do it one time only

waxen scroll
#

too small

subtle glen
#

if it trips again it wont turn on the power

#

and if you move that orange cover on the side, you disable the auto turn on feature

tough bluff
#

You can literally see virtual breaker boxs on our management software

subtle glen
#

AAA

gritty owl
#

that's pretty awesome

subtle glen
#

like power plants?

tough bluff
#

It reminds me of a virtual office pc sim

#

Yes and we have a power plant

rocky badge
#

Solar iirc xd

subtle glen
#

three phase transformer outside?

tough bluff
#

We are 100% off pole

#

Solar

subtle glen
#

mmm

tough bluff
#

We have 3 fields with it

gritty owl
#

Oh, that's nice

tough bluff
#

Powers everything

subtle glen
#

dont you like the idea to power your stuff with "GASOLINE"??

gritty owl
#

I hope to get solar panels some day

tough bluff
#

As we are a green company

subtle glen
#

jk

tough bluff
#

Our steel mill produces zero black smoke

#

It's all filtered

subtle glen
#

my dad's company planted N trees to compensate the co2 they produce

tough bluff
#

We clear trees

#

And plant in a new location stupid far away

#

Then we used the cleared area make a new building

#

And process wood

subtle glen
#

ohh you use one of those machines that "hug" the tree and transport it away?

tough bluff
#

The entire building goes up for practical nothing since we manufacture materials

#

We grab it

#

And it gets put into a truck

#

Then the mill does the rest

#

We can process a few thousand trees a day

subtle glen
tough bluff
#

No

#

We arent cutting the stump till later

subtle glen
#

it doesnt cut it

tough bluff
#

We are trying to kill the tree

tough bluff
#

Not save it

subtle glen
#

ahhahahah

#

the heli seems small from that perspective

tough bluff
#

We make studs and plywood

rocky badge
#

@waxen scroll lol

gritty owl
#

Oh, that's nice. Putting them trees to use

tough bluff
#

Wood that is used in house building

#

I'm a administrator for the farming and wood

#

I dont touch steel

waxen scroll
subtle glen
#

@waxen scroll that model seems to be a 32 A "anti overload" breaker+ "anti short socket" breaker with a current to trip it of 300 mA (which is the one we need to have on our breakers)

#

dunno how u call your breakers

waxen scroll
#

you can see the power jumping to the chopper

#

that little blip

subtle glen
#

yep

#

ahh that ZZZZ sound is satisfying

#

(referred to the Americans) how do you call the breaker that trips for overload and the one for short circuit ?

waxen scroll
#

overload i believe we call a main

#

short circuit is just called circuit breaker

subtle glen
waxen scroll
#

yes

gritty owl
#

Yep

subtle glen
#

still dont like that open neutral bus bar

gritty owl
#

One very clean looking breaker panel though

subtle glen
#

not mine tho

#

we have totally different systems

waxen scroll
#

my breakers are color coded on the wires

subtle glen
#

lol

#

now i wanna see it

gritty owl
#

Same. haha.

waxen scroll
#

im too lazy to open it

#

๐Ÿ˜„

subtle glen
#

ohh ๐Ÿ˜”

gritty owl
#

It just drives me nuts when electricians use green as a hot wire. So many shocks because of that...

subtle glen
#

WTF???

#

green??

waxen scroll
#

my house also has a high voltage fire alarm and high voltage smoke detectors

gritty owl
#

Oh, that's nice

waxen scroll
#

๐Ÿ˜„

subtle glen
#

wdym high voltage

#

they use 120 v?

waxen scroll
#

yes

subtle glen
#

ah

#

well, u dont have to change batteries

waxen scroll
#

you do

#

battery backup for power outages

subtle glen
#

ahhh, well

#

we dont even have fire alarms in home soooo

waxen scroll
#

its code here.... they're wired together so if one goes off they all do

subtle glen
#

lol

#

in the middle of the night

#

weeeeeeee

#

i mean thats its purpose

waxen scroll
#

then the high voltage fire alarm is part of a sprinkler system

#

water flow trips it

subtle glen
#

yeah but do u have methane alarms?

waxen scroll
#

no, just carbon monoxide

gritty owl
#

I need to get some better alarms at our house...I think they're all expired too. lol

subtle glen
#

i need to get an alarm, i dont have one

waxen scroll
#

then i layered a low voltage alarm ontop of this whole thing

gritty owl
#

geez, that's neat

waxen scroll
#

potato quality

subtle glen
#

controller for alarms?

gritty owl
#

that's really nice

subtle glen
#

do you live in a castle with 100+ rooms

waxen scroll
#

3000sqft

subtle glen
#

lemme convert that in m2^

waxen scroll
#

so that little relay circuit to the right is an interface that the high voltage alarms can trip

#

it waits 10sec before telling the low voltage that theres an alarm

#

helps prevent falses

subtle glen
#

can i go there and light a lighter under it?

waxen scroll
#

if you do, bring ear protection

#

all of this is seriously loud

#

๐Ÿ˜„

subtle glen
#

like those small but annoying fire alarms

waxen scroll
#

its got two sirens and then the smoke detectors themselves are redic loud

subtle glen
#

weewooweewoo

#

so you can let the neighbours theres a fire in ur house

waxen scroll
#

and @clear igloo no thats not ethernet in there

subtle glen
#

does it call the fire department too?

waxen scroll
#

thats an RS485 bus

#

it does

subtle glen
#

ive seen such a module for arduino stuff

waxen scroll
#

on the security side i think i have about 35 sensors attached to it

subtle glen
#

that panel doesnt stand to my "super tidy" breaker. Now with the wrong breakers inside

waxen scroll
#

whats neat is theres a module for my home automation kit, vera, which any time a sensor is tripped the alarm tells vera

#

so i can do things like "if garage opens, turn on outside lights"

#

no additional sensors

subtle glen
#

cool stuff

#

pretty interested in domotics too

#

do american houses have "the safety rope" in the shower? i dont know how to call it

waxen scroll
#

hmm... not that i know of? not sure what you mean but theres no rope thing

subtle glen
#

wait lemme search for a pic

waxen scroll
#

so i went balls to the wall

#

door/window sensors, garage sensor

#

motion

#

glass break

#

if you DIY you might as well

#

not like you're paying $$$$$ to a company

subtle glen
#

wait let me go in the bathroom to take a picture, i cant find a decent one

waxen scroll
#

lol

gritty owl
#

I hope to build a new house and go crazy with the sensors as well

waxen scroll
#

its a pain in the ass because sensors are mostly in outside walls

gritty owl
#

Yeah, it's pretty hard to do for an existing home

waxen scroll
#

you can go wireless but i didnt want any batteries

#

35 batteries every 6 months or so? LOL no

clear igloo
#

what kind of sensors you looking at?

#

Mine need changing every 2 years or so

waxen scroll
#

who?

clear igloo
#

You

gritty owl
#

Yeah, the DIY home alarms pretty much all use battery?

waxen scroll
#

as far as wireless? none. i never researched or gave it a chance

#

im OK wiring

subtle glen
#

me too

clear igloo
#

Ah, that's cool

gritty owl
#

What wired sensors do you use?

#

Might bookmark them for the future., haha

rocky badge
#

Lol

waxen scroll
#

@gritty owl you can use any sensors, 2 wire or 4 wire... theres no compatibility issue. i use honeywell motions and glass breaks, then whatevers cheap and good for the doors and windows

gritty owl
#

Sounds good. haha

rocky badge
#

@gritty owl you're in the Ubiquiti server thinkies

gritty owl
#

haha, yep.

rocky badge
#

I don't chat in there

#

I'm just there ๐Ÿ˜„

waxen scroll
#

im going to put a zone expander on this alarm and add water detection

gritty owl
#

Same. I've bought some stuff on the ubiquiti server though

waxen scroll
#

make sure the basement and laundry doesnt leak

gritty owl
#

That's pretty nice

subtle glen
#

basically there is this rope that is connected to a push switch (like a bell one) connected to a buzzer (like a doorbell one). In case you feel sick during a shower or in case of emergency, you pull the rope and the buzzer starts ringing

waxen scroll
#

yeah we dont have that anywhere

subtle glen
#

interesting

gritty owl
#

Yeah, I've never seen that rope

subtle glen
#

i used to pull it to tell my dad i finished showering when i was a kid

#

i told him "2 pulls and ive done showering, 1 pull im in trouble"

subtle glen
#

@waxen scroll ofc you like running cables, you have drywalls and wood...

waxen scroll
#

its going to make wire running stupid easy

#

yep

subtle glen
#

thats something im jealous about american houses

#

for the rest, i prefer italian things

#

especially electrical ones

#

like the plugs we have, the switches we have, our breakers, our voltage...

waxen scroll
#

i try to DIY high voltage too

subtle glen
#

you have dual phase

#

you can 240v

waxen scroll
#

getting people to do it out here is stupid expensive

subtle glen
#

we have it standard

gritty owl
#

I wish residential homes get three phase here

waxen scroll
#

$150 to switch a light switch to zwave

subtle glen
#

or you can request 3 phase

waxen scroll
#

how stupid

subtle glen
#

the power company puts you a 3 phase meter unlocked to 10 Kw min

gritty owl
#

Sadly not all areas in the US you can get three phase. Usually only in the industrial areas where the poles have the wires needed for it

subtle glen
#

still dont understand why they choosed 110 v

waxen scroll
#

we might be able to get 3 phase here but my neighborhood is far from the pole, so i dont know what they actually put in the neighborhood boxes

clear igloo
#

@waxen scroll is that what they wanted to charge you do to that switch?

waxen scroll
#

@clear igloo yep

subtle glen
#

maybe a janky solution. A mono phase motor coupled with a three phase one xD

clear igloo
#

lol, no thanks. I did all mine myself, not paying $150 per, lol

waxen scroll
#

most of my boxes have a neutral wire, so theres no work

subtle glen
#

i rly want to put a grounding rod in my garage but, how do i break (reinforced maybe) concrete

waxen scroll
#

i was unsure about the 3 way wiring of the switch so i wanted to call a guy

#

when he told me the cost i was like NO

clear igloo
#

haha, yah

waxen scroll
#

i "toned" out the wires myself

subtle glen
#

hell no, to the no no noo

waxen scroll
#

they werent marked so i was a little nervous about DIY

subtle glen
#

use a phase tool to find which is the phase

#

dunno the name

clear igloo
#

Ah, yah, that can be nerve wracking at first

waxen scroll
#

its not the phase/hot i didnt know, its the two traveler cables

gritty owl
#

yeah, it's tricky to figure out

subtle glen
#

ah

gritty owl
#

I've gotten shocked a few times with 3 way troubleshooting

#

lol

subtle glen
#

shocked with 110v

#

pffff

#

try getting shocked with 230

waxen scroll
#

12v at 100 amps

gritty owl
#

I've been shocked by 480V before

#

Not fun. lol

subtle glen
#

now we can open a discussion

#

its the voltage that kills you

#

i believe electroboom

waxen scroll
#

ive heard its the amperage that kills you

clear igloo
#

^

waxen scroll
#

12v can kill

gritty owl
#

Well, voltage makes it more likely to kill you

clear igloo
#

That's why 10K volts from a stun gun doesn't kill you

#

with low amperage

waxen scroll
#

so the reason DC can kill is theres no alternation

gritty owl
#

Yep

waxen scroll
#

you hold onto it and lock in

#

no break

#

๐Ÿ˜„

clear igloo
#

Yah

subtle glen
waxen scroll
#

that guys eyebrows creep me out

subtle glen
#

lol look at its outro

waxen scroll
#

@rocky badge why are you not discussing anything

#

๐Ÿ˜ƒ

rocky badge
#

I'm playing in VR

#

I'm legit sweaty from it

clear igloo
#

"playing" xD

subtle glen
#

i guess its cause we went a lil but out of theme

waxen scroll
#

i play with myself too sometimes

#

its normal

rocky badge
#

@waxen scroll I punched the wall

waxen scroll
#

v_v

#

LOL

rocky badge
#

I didn't see it

clear igloo
#

You're not supposed to play that hard, lol

rocky badge
#

It's Superhot VR

waxen scroll
#

good. now blob can learn drywall repair

rocky badge
#

You're punching people

clear igloo
#

^

gritty owl
#

That's some dedication

rocky badge
#

There's no damage

clear igloo
#

Did you cuddle with the wall after?

rocky badge
#

to me, my controller, or the wall

subtle glen
#

do some american houses have power coming from underground cables? or theres always that pole in the street that gives power

clear igloo
#

Most of the cities and towns do poles to a point and then underground

waxen scroll
#

all i got to do is press PLAY

rocky badge
#

Lol

clear igloo
#

DO EETTT!!

rocky badge
#

Rip my laptop

gritty owl
#

Toasty

rocky badge
#

I'm glad I turned off my server before this

clear igloo
#

That's how hot my 7900X get's after 20 minutes at 100% ๐Ÿ˜ƒ

waxen scroll
#

is that unlicensed aida64 i see?

rocky badge
#

It would get hot af in here

#

It's HWmonitor

clear igloo
#

OOOOO! Unlicensed!! I'm calling the internet police

subtle glen
#

my grandma pc shuts off for overheating if i play minecraft

rocky badge
#

I do have Aida 64 tho

gritty owl
#

I haven't used it myself...mostly use Intel Burn Test for OC

subtle glen
#

that laptop has win vista, an intel centrino, 512 mb of video ram

clear igloo
#

Vista shudder

gritty owl
#

Wow, been a while since I've seen centrino. haha

waxen scroll
#

using putty when secureCRT exists

rocky badge
#

XD

subtle glen
#

@clear igloo now i reiceve pop ups saying "windows vista is not supported" uuuu

#

or on chrome "you wont reiceve updates cause win vista is not supported"

waxen scroll
#

@clear igloo some implementations i got like 8 tabs open

clear igloo
#

8 tabs of CRT?

waxen scroll
#

yeah

rocky badge
#

Who tf is using all of my internet xd

subtle glen
#

will i fill my 48 port switch ๐Ÿค” .those are the questions i think about before going to sleep

rocky badge
subtle glen
#

me, im stealing some mbps

waxen scroll
#

i got a 24 port switch because im sensible

subtle glen
#

bought an 8 port 100mbps switch

rocky badge
#

Wow, it's downloading at 1.5MB/s....

subtle glen
#

now you know how i feel

#

i download at 1.2

waxen scroll
#

all the wires!!!

subtle glen
#

thats tidy compared to mine

rocky badge
subtle glen
#

all the wires

waxen scroll
#

japanese power tools

subtle glen
#

wut

waxen scroll
#

the blue charger

subtle glen
#

its the makita drill battery

#

u got some good eyes

rocky badge
#

wtf Steam...

#

or Spectrum

waxen scroll
#

its steam

rocky badge
#

I think its Spectrum

waxen scroll
#

im going to laugh if its the pf box that i told you not to use

subtle glen
#

that is hosted on steam servers

waxen scroll
#

๐Ÿ˜„

subtle glen
#

ahahahaha

#

do you use pfsense

#

?

rocky badge
#

Stupid Spectrum

subtle glen
#

seems normal to me

clear igloo
#

lol

rocky badge
waxen scroll
#

you went and put in pf and now your internet is broke

subtle glen
#

why no pfsense @waxen scroll

rocky badge
#

I'm not using pfsense right now

waxen scroll
#

because it runs on h/w that cant accelerate things with asics

rocky badge
subtle glen
#

didnt understand a single word ๐Ÿ™ƒ

#

thats lurick's language

waxen scroll
#

basically high bandwidth usage makes the cpu 100% because packets are processed there

subtle glen
#

mine has an i5 and 4 gb of ram so i guess its good

waxen scroll
#

yeah probably, dunno

subtle glen
#

and i have a 9 /0.5 mbps connection sooo

#

what high bandwith

rocky badge
#

Mine has dual X5355s

#

and 16GB of ram

subtle glen
#

but dont worry, cant make it work

waxen scroll
#

asic is like a secondary CPU whose only purpose is to do packets

subtle glen
#

does it work @rocky badge

waxen scroll
#

so its fast as hell

rocky badge
subtle glen
#

ahh we are back online

#

too many mbps for my taste

rocky badge
#

When GPU drivers reset

subtle glen
#

Looking for someone that want to share me its pfsense setup config. Im desperate

waxen scroll
#

why

#

isnt it easy to set up?

rocky badge
#

Yes

subtle glen
#

for everyone yes

#

for me apparently no

#

if it works, i get locked out the gui

waxen scroll
#

i thought pfsense was basically plug and play

rocky badge
#

Not really XD

subtle glen
#

if i can access, i get the internet icon with the triangle

#

i think some dns things are not set up properly

waxen scroll
#

you get DHCP?

subtle glen
#

yeah, i get an ip and sometimes i manage to access the gui

waxen scroll
#

"sometimes"

subtle glen
#

yeah

waxen scroll
#

sounds like an IP conflict or something

subtle glen
#

i put the gateway ip but 1 out of 10 times it works

#

most important thing, i dont get internet

waxen scroll
#

rule it out by putting your computer directly into the LAN port of the PFsense

#

see if the gui works 100%

subtle glen
#

lemme turn it on

#

i prob reset pfsense like 20 times

#

im pretty sure its a dns problem

#

lets see if i can access the web interface

rocky badge
clear igloo
#

Did you try crying onto the modem?

rocky badge
#

No

#

That will break it

gritty owl
#

lol, the modem lives off of your tears though

rocky badge
#

And Charter will replace it with router and modem combo

waxen scroll
#

wow i actually had to laugh at that

rocky badge
#

Which will become a WiFi AP

waxen scroll
#

seems like a futurama joke

subtle glen
#

Hey hey @waxen scroll guess what

#

192.168.1.120 is unreachable

#

that's the gateway ip sooo no web gui

waxen scroll
#

thats directly plugged into it huh?

subtle glen
#

Yeah

#

Lemme.ping the machine

#

Pfsense gave me the ip, the pc sees the 192.168.1.120 ip as a gateway but cant ping it

#

Requesti timed out

waxen scroll
#

is it possible that .120 isnt the IP and the DHCP is handing out the wrong gateway address?

#

does it tell you who the dhcp server is?

#

ipconfig /all

subtle glen
#

Pf sense say my pc is down

#

No way, there is also the lease time in there

waxen scroll
#

whats arp -a say?

#

also it says your DNS server is 1.1

#

that could be a problem too

subtle glen
#

Ahhh so I was right

#

Dns problem

waxen scroll
#

well everything adds up, so idk maybe your install is just borked if you cant access the GUI by IP

subtle glen
#

I mean I get confused, as dns ip, should I put the one of the main modem/router or the wan one

waxen scroll
#

whatever has the WAN connection

#

but if you took the computer and plugged it into PFsense then obviously 1.1 isnt reachable

#

the only other thing it can be is subnet mismatch

#

but i doubt its that

#

the IPs are close enough together

#

and you have arp

subtle glen
waxen scroll
#

so nuke the box and start over maybe

subtle glen
#

Fresh reinstall?

waxen scroll
#

yes

subtle glen
#

Or throw it out the window

waxen scroll
#

window unless you really want to try it

subtle glen
#

Hahahaha

#

Wait a minute

#

If I unplug the wan cable I can access the gui

waxen scroll
#

oh jesus theres your issue

#

linux doesnt handle two interfaces in the same subnet well

subtle glen
#

I have 3 in that machine

#

One is not set up yet

waxen scroll
#

WAN and LAN cant be in the same subnet

#

you should make a new subnet for LAN

subtle glen
#

Ffs

waxen scroll
#

and if you jacked this into your switch it needs to be on a new VLAN so DHCPs dont conflict

#

unless the WAN network is all static IP

subtle glen
#

Pf sense is just plug and play

#

Sureee

waxen scroll
#

it kind of is, its not built to do the way you want though without more planning

subtle glen
#

So I cant have the same subnet as the one the router has

#

MMMmmm

waxen scroll
#

you can... on the WAN side only

subtle glen
#

....

waxen scroll
#

you're using two routers right? one of them holds your internet, one of them is pfsense

subtle glen
#

Changed subnet, gui goes into "site cant be reached" mode, wan doesnt get an ip after plugging it in

#

I changed the lan subnet

#

Yeah

waxen scroll
#

what did you change it to

subtle glen
#

16

waxen scroll
#

that wont work

#

xD

#

you mean /16 right?

subtle glen
#

But still, wan doesnt get an ip

#

Yeah

#

Now it got the ip

waxen scroll
#

change it to 192.168.2.120/24

#

for LAN

#

then connect computer to it and see if GUI works

#

make sure DHCP gave you the right subnet too

rocky badge
#

ewwwwww

#

192.168.X.X

waxen scroll
#

dunno if you need to change that seperate

subtle glen
#

Put lan on 192.168.1.120/24, the pc gets the 255.255.255.0 gui works with wan unplugged

waxen scroll
#

linux acts crazy with two interfaces in the same subnet and you just proved that

subtle glen
#

Funny how pf sense asks If you want to go back to http, and after you said NO the gui is on http still

#

And chrome goes NON PROTECTED AREA

waxen scroll
#

ive done hacking to make that type of thing work on linux... without the hacks what happens is return traffic always uses one interface even though the interface has a different IP on it

subtle glen
#

What if I put all the 3 interfaces on the same subnet

#

Everything goes boom?

waxen scroll
#

same problem.... return traffic uses a different interface and things dont work

subtle glen
#

Thanks pfsense ๐Ÿ˜€

waxen scroll
#

@clear igloo today you learned

subtle glen
#

OOO

#

Network admins dissing

waxen scroll
#

you have to go in with iptables mangle and tell it to pay attention to mac addresses and mark them so that traffic is sent back out the correct interface

#

its a mess

subtle glen
#

How is it possible that pf sense didn't fix something that important

waxen scroll
#

idk, no same subnet on two interfaces is a pretty basic thing

subtle glen
#

Not for me

waxen scroll
#

if you try it on a cisco router, the software will tell you no

Cisco is smart

Sorry sir

I'm blaming charter now xd

subtle glen
#

Restarting the modem?

waxen scroll
#

most of what i do for my job IRL is to take project requirements from the business and engineer network designs around those requirements. i dont troubleshoot or monitor anymore for the most part

subtle glen
#

Does it come back normal if you stop charter

#

So you tell the enterprise What to install in their network?

rocky badge
#

@waxen scroll lol that seems fun

waxen scroll
#

i do, yes

subtle glen
#

By following their instructions?

#

Cool

#

Pretty sure lurick does the same

waxen scroll
#

i design it, write the configurations, then deploy it

subtle glen
#

Then the slaves go crimp thousands of eth cables?

#

Or you also do that part

waxen scroll
#

yep. got slaves for cabling and racking, then slaves for monitoring it for problems and correcting them

subtle glen

Hahahahah

rocky badge

Wait no, I blame Windows now @waxen scroll

if i cause a network outage it will be in the news

do you work at the worlds biggest internet node?

no, cameras arent allowed

those places are boring

subtle glen

why

waxen scroll

cool at first then the wow factor dies pretty fast

its just a bunch of cages with rows of racks and servers

dont say that, you make me regret my decision to become a network admin

waxen scroll

nothing exciting about that

subtle glen

well paradise

#

do you work at google then?

waxen scroll

im not saying where i work lol

subtle glen

firefox, thats it

From what I hear, Google is an extremely high pressure environment

google is a high SJW environment, so i will never work there

they have slides in the office

@clear igloo I wanna kill Charter, my modem, and my router XD

#

A) Who wouldn't want to kill Charter?

#

They're crap ๐Ÿ˜„

subtle glen
#

at first i would say that seems like the cooling room

waxen scroll
#

nope, its a server room

#

those black devices on the cages are hand scanners

subtle glen
#

i think i see a piece of server

#

no retina ones

clear igloo
#

uses laser vision I see the gear

rocky badge
#

XD

subtle glen
#

?

waxen scroll
#

they're not going to have many pics of actual racks online because customers dont like pictures of their shit on the internet

subtle glen
#

@ancient vigil on the left side theres something black

#

seems a piece of rack ๐Ÿค”

#

yeah

#

so there are servers

waxen scroll
#

it is yes

subtle glen
#

those empty cages makes me think about wasted space

waxen scroll
#

its where multiple internet providers hook up

subtle glen
#

one seems to have the door open

#

so some sort of internet backbone/node

waxen scroll
#

so the internet providers exchange traffic between them in that facility

subtle glen
#

does that company hook isp's in italy aswell?

#

ready for new babies to slide in

waxen scroll
#

probably? if the italy ISPs want a united states presence

subtle glen
#

i dunno. Wind vodafone telecom infostrada tiscali

#

do u recognize any of them?

waxen scroll
#

this stuff is in chicago so theres no undersea fiber right there

#

vodaphone

#

fone, whatever

#

lol

#

british telecom is there

#

chinatelecom is there

#

theres 100s of ISPs really

subtle glen
#

dunno if its like british telecom is like the telecom we have here

#

they rent servers there or they use that place as gateway to the backbone

waxen scroll
#

russia is in there

#

so is ukraine

#

this facility also rents space to non-telecoms

#

some companies like financials want to be right at the connection points to the exchanges

#

1ms is life and death

subtle glen
#

i want 0 ms

#

which is imposible but still

waxen scroll
#

its possible

#

you're thinking in terms of ICMP (ping)

subtle glen
#

cant reach 0 ms even between my pc and the router

waxen scroll
#

tcp traffic and udp traffic can do it

subtle glen
#

about having 1 ms of ping between the pc and the router?

#

eyyyy someone else that uses 192.168.

waxen scroll
#

so ICMP needs to be processed by the routers CPU and thats less important traffic than other types

#

so it can be over 1ms

subtle glen
#

about 192.168?

#

why ppl dont like 192.168 ๐Ÿ˜ฆ

i feel for the providers who get calls from angry gamers who arent their customer about traceroute readings because they mean jack shit

@waxen scroll why would an isp hook to ur company to connect to the internet, cant they hook themself up?

@subtle glen im not sure the question?

Every time the servers are down, they get hate filled teenagers flooding their voicemail xD

subtle glen
#

@waxen scroll you said that isp's use you company to connect to the backbone right?

#

or something similar

waxen scroll
#

no they cant connect themselves

clear igloo
#

It's called an interconnect, they need to connect to each other somewhere

waxen scroll

they need to rent space and pay for an interconnect

cant i lay down a cable from my isp to the other?

And do that for how many other ISPs?

its not impossible to lay a cable but its HARD

clear igloo

#

You'

subtle glen
#

no like between isp and isp

clear igloo
#

You'd create a full mesh network, that's expensive and time consuming

waxen scroll
#

one company i worked for deprioritized ICMP so it would add like 20ms

#

gamers hated it

waxen scroll
#

1 and 2 are both right.

#

equinix has a product that does #1

#

err

#

#2

#

lol

subtle glen
#

definition of the year would say

waxen scroll
#

equinix does a thing where ISPs can buy one fiber and use vlans on that fiber to connect up to many ISPs

#

instead of running tons of fiber

#

no, i think separate fibers is still popular

#

if that one fiber dies think of all the loss

subtle glen
#

ill take my inflatable toy boat and ill lay my cable

waxen scroll
#

the popular thing for non-ISPs to do now is to purchase space on dark fiber, terminate the other side into a carrier hotel, then do their business that way

#

better access to azure/aws

#

whatever

subtle glen

here i dont even have 100 mbps fiber....

u get low latency there

why arent you working for one then?

cause im 16

and i cant configure a switch

waxen scroll

well its time to do the CCNA then

subtle glen
#

oh god

waxen scroll
#

ive only ever been a CCNA and look where i am

subtle glen
#

aint ready

waxen scroll
#

you dont get hired for having a CCNA anymore

subtle glen
#

just imagine working at those exchange points: running in the servers hallway surrounded by cables maybe with Happy together -the turtles

waxen scroll
#

the truth is, a CCNA doesnt prepare you for working on networks, even small ones. its close for small ones

#

CCNP is what you need because BGP and advanced OSPF

subtle glen
#

so uhhhh, where do you start xD?

waxen scroll
#

you start with CCNA, then lots of trial and error, read CCNP but maybe not try to get it, get work experience, then take CCNP

#

CCNP is hard for even myself to pass

#

you have to think like cisco

subtle glen
#

like lurick

#

one of the questions you can find in those tests?

waxen scroll

ive done cisco and extreme

some juniper but not enough to really mention it

ct what?

waxen scroll
#

@subtle glen On what does BGP base the selection of the best path? [speed] -or- [AS routing policy] -or- [number of routers to reach a destination network] -or- [bandwidth and delay] ?

subtle glen

true

#

bandwith delay

#

this one seem kinda easy

#

cant answer it but still

waxen scroll

they're easy for people with job experience

speed

#

dont know what as routing is so ill reject that

AS Routing Policy

subtle glen

waxen scroll

honestly the test is 10x harder than this

subtle glen

ok ok another question

im just getting bad sample questions from cisco online

i have cisco stuff laying around

#

look what i found

What wireless standard do autonomous vehicles use to communicate?

@subtle glen that looks like a nice bridge

no latency wit htose

waxen scroll

oh heres a good question

subtle glen
#

go for it

waxen scroll
#

@subtle glen why would i manage a router using a /32 on a loopback interface instead of anything else

subtle glen
#

shit

#

ok ok wait

#

we are talking about subnets

waxen scroll
#

sure

subtle glen
#

why a 32 uh?

#

cause uhhh

#

it has something special to avoid loopback?

#

no no wait

rocky badge
#

๐Ÿ˜„

subtle glen
#

tf is a loopback interface

rocky badge
subtle glen
#

i got this

waxen scroll
#

is loopback even in CCNA? i dont remember

clear igloo
#

Inband management of the router

#

Conservation of IP addresses in a spine-leaf topology by using loopback 0 and ip unnumbered interfaces

#

Single peer point for BGP

waxen scroll
#

if interface g0/0/0 with IP 192.168.1.1 is being used for management and g0/0/0 loses link, i cant talk to my device on that IP anymore... big problem if you have logging and other items on that IP

clear igloo
#

^

subtle glen
#

you use redundancy

waxen scroll
#

a /32 on a loopback interface can be accessed using any interface on the router

clear igloo
#

If you remember to redistribute it to your routing protocol

waxen scroll
#

@rocky badge set one up on your home lab, pls

#

use 1.1.1.1/32

rocky badge
#

XD

clear igloo
#

๐Ÿ˜›

subtle glen
#

192.168

clear igloo
#

In a spine-leaf topology you lose and then restore a border gateway leaf. You're running the network at 85% of max route scale and you have default timers implemented for the BGW election timers. What happens when the election timer pops?

subtle glen
#

do i have to answer

rocky badge
#

yes

clear igloo
#

A. The network explodes
B. You pull your hair out and scream for 5 minutes
C. Convergence events upwards of 10 minutes occur in the network
D. You're fired because you let the leaf go down in the first place

subtle glen
#

D

waxen scroll
#

i think the tl;dr from today is that networking is hard and it isnt smart for medium business and higher to let non-networkers touch it

clear igloo
#

I concur, networking is hard but it's fun and rewarding too if you have the passion for it

subtle glen
#

A sounds tempting too

waxen scroll
#

@subtle glen its going to take years

#

buckle up

rocky badge
#

XD

subtle glen
#

๐Ÿ™„

rocky badge
#

Windows is being dumb again

#

Keyword: again

clear igloo
#

The answer is C. After the election timer expires the election process takes place and the leaf is brought back into the role of a border gateway. Because you were using default timers you experience a long convergence event due to the fact that the router now has to dump and reprogram the BGP RIB after assuming the new role and rid itself of the reflected routes. To avoid this in the future if route scale higher than ~60% is expected then timers should be adjusted to roughly 300 seconds to ensure minimal to zero convergence on restore

You search for them and you hope you have the time to learn it

how do you know theres something new in the first place

clear igloo
#

Blog posts, newsletters, research, etc.

#

If something in your area of study is new, you'll hear about it somehow

Because you're always looking

subtle glen
#

alright

#

like when you go to the water dispenser and you hear co workers talking

clear igloo
#

That's another way

waxen scroll
#

heh

#

the real way is that you invite sales people to your office

#

they tell you whats new

#

then you buy it and use professional services to get it going

subtle glen
#

or

#

you run the company off unmanaged switches

waxen scroll
#

let me know how it goes

subtle glen
#

give me an office and some switches

waxen scroll
#

nope.

subtle glen
#

you wont have different segments of network but it would work

#

think so

waxen scroll
#

you can have different segments of network

#

the broadcast is going to be a problem

you change pools on the router ports and change subnets
