think of all the wives and kids CCIE holders neglect
Yes
No, I don't need to for my rack at home
@waxen scroll lol
All the power is controlled via managed IP systems
fffff
My office and the it office is miles away from the server room
is that place some sort of disneyland for network admins
It would be a inconvenience to drive back
Lol
That's pretty awesome
lol
Lol
Sounds like my friend
i have never been to disneyland
Excpet he doesn't work
I go every year but can't go on rides
Rip
Disney world *
i got multiple people who work at disney world that can swipe me in the gates
i never pay

BUT can you remotely turn on the breaker if the power goes out and get a notification UHH?
Yes
MMMM
my main breaker is one 50 yrs old with fuses
The s may stand for smart but probably not for secure 
TBH fam, i wouldnt want a breaker turned on remotely... you need to ask "why did it trip?"
fam
that trips for overload
when old people use words like lit, fam, etc
We have a server that manages breakers and electrical
right, if it overloaded you need to go on site and ask why
WTF, a server even for that????
I'll get a notification on my dash board if something goes off
too many appliances
@rocky badge thats lit AF
Wood mill
Ewwwww
Alot of other growing operations
fo shizzle dawg
You used the word lit
my generation invented memes
the me me's
Memes make me question every thing
Indeed. haha
i called them "meh mes" for the longest time
We have a meme in my office and it bothers me so much
@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
AHHH
whats the amperage of that thing
There just connected to a management system
lemme check
You need to send a message to get them to click on
yeah, I wouldn't want a breaker to auto turn on. haha
Yeah
that thing looks like it cant do past 200a
you can set it to do it one time only
too small
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
You can literally see virtual breaker boxs on our management software
AAA
that's pretty awesome
like power plants?
Solar iirc xd
three phase transformer outside?
mmm
We have 3 fields with it
Oh, that's nice
Powers everything
dont you like the idea to power your stuff with "GASOLINE"??
I hope to get solar panels some day
As we are a green company
jk
my dad's company planted N trees to compensate the co2 they produce
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
ohh you use one of those machines that "hug" the tree and transport it away?
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
it doesnt cut it
We are trying to kill the tree
Not save it
We make studs and plywood
@waxen scroll lol
Oh, that's nice. Putting them trees to use
Wood that is used in house building
I'm a administrator for the farming and wood
I dont touch steel
@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
yep
Playing With High Voltage http://milikeit.com/ crewing With High Tension Power Lines Electrical Workers Play With Power Lines Messing With High Tension Power...
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 ?
and those 2 cables at the top are the phase right?
yes
Yep
still dont like that open neutral bus bar
One very clean looking breaker panel though
my breakers are color coded on the wires
Same. haha.
ohh ๐
It just drives me nuts when electricians use green as a hot wire. So many shocks because of that...
my house also has a high voltage fire alarm and high voltage smoke detectors
Oh, that's nice
๐
yes
its code here.... they're wired together so if one goes off they all do
yeah but do u have methane alarms?
no, just carbon monoxide
I need to get some better alarms at our house...I think they're all expired too. lol
i need to get an alarm, i dont have one
then i layered a low voltage alarm ontop of this whole thing
geez, that's neat
controller for alarms?
that's really nice
do you live in a castle with 100+ rooms
3000sqft
lemme convert that in m2^
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
can i go there and light a lighter under it?
its got two sirens and then the smoke detectors themselves are redic loud
and @clear igloo no thats not ethernet in there
does it call the fire department too?
ive seen such a module for arduino stuff
on the security side i think i have about 35 sensors attached to it
that panel doesnt stand to my "super tidy" breaker. Now with the wrong breakers inside
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
cool stuff
pretty interested in domotics too
do american houses have "the safety rope" in the shower? i dont know how to call it
hmm... not that i know of? not sure what you mean but theres no rope thing
wait lemme search for a pic
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
wait let me go in the bathroom to take a picture, i cant find a decent one
lol
I hope to build a new house and go crazy with the sensors as well
its a pain in the ass because sensors are mostly in outside walls
Yeah, it's pretty hard to do for an existing home
you can go wireless but i didnt want any batteries
35 batteries every 6 months or so? LOL no
who?
You
Yeah, the DIY home alarms pretty much all use battery?
me too
Ah, that's cool
Lol
@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
Sounds good. haha
haha, yep.
im going to put a zone expander on this alarm and add water detection
Same. I've bought some stuff on the ubiquiti server though
make sure the basement and laundry doesnt leak
That's pretty nice
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
yeah we dont have that anywhere
interesting
Yeah, I've never seen that rope
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"
@waxen scroll ofc you like running cables, you have drywalls and wood...
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...
i try to DIY high voltage too
getting people to do it out here is stupid expensive
we have it standard
I wish residential homes get three phase here
$150 to switch a light switch to zwave
or you can request 3 phase
how stupid
the power company puts you a 3 phase meter unlocked to 10 Kw min
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
still dont understand why they choosed 110 v
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
@waxen scroll is that what they wanted to charge you do to that switch?
@clear igloo yep
maybe a janky solution. A mono phase motor coupled with a three phase one xD
lol, no thanks. I did all mine myself, not paying $150 per, lol
most of my boxes have a neutral wire, so theres no work
i rly want to put a grounding rod in my garage but, how do i break (reinforced maybe) concrete
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
haha, yah
i "toned" out the wires myself
hell no, to the no no noo
they werent marked so i was a little nervous about DIY
Ah, yah, that can be nerve wracking at first
its not the phase/hot i didnt know, its the two traveler cables
yeah, it's tricky to figure out
ah
12v at 100 amps
ive heard its the amperage that kills you
^
12v can kill
Well, voltage makes it more likely to kill you
so the reason DC can kill is theres no alternation
Yep
Yah
Heard a few people say it is the current that kills, not the voltage. I have to disagree. Read more at: http://www.electroboom.com/?p=450 Follow me on Facebo...
that guys eyebrows creep me out
lol look at its outro
"playing" xD
i guess its cause we went a lil but out of theme
@waxen scroll I punched the wall
I didn't see it
You're not supposed to play that hard, lol
It's Superhot VR
good. now blob can learn drywall repair
You're punching people
^
That's some dedication
There's no damage
Did you cuddle with the wall after?
to me, my controller, or the wall
do some american houses have power coming from underground cables? or theres always that pole in the street that gives power
Most of the cities and towns do poles to a point and then underground
Lol
DO EETTT!!
Toasty
I'm glad I turned off my server before this
That's how hot my 7900X get's after 20 minutes at 100% ๐
is that unlicensed aida64 i see?
OOOOO! Unlicensed!! I'm calling the internet police
my grandma pc shuts off for overheating if i play minecraft
I haven't used it myself...mostly use Intel Burn Test for OC
that laptop has win vista, an intel centrino, 512 mb of video ram
Vista shudder
Wow, been a while since I've seen centrino. haha
using putty when secureCRT exists
XD
@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"
@clear igloo some implementations i got like 8 tabs open
8 tabs of CRT?
yeah
Who tf is using all of my internet xd
will i fill my 48 port switch ๐ค .those are the questions i think about before going to sleep
me, im stealing some mbps
i got a 24 port switch because im sensible
bought an 8 port 100mbps switch
Wow, it's downloading at 1.5MB/s....
thats tidy compared to mine
japanese power tools
wut
the blue charger
its steam
I think its Spectrum
im going to laugh if its the pf box that i told you not to use
that is hosted on steam servers
๐
seems normal to me
lol
you went and put in pf and now your internet is broke
why no pfsense @waxen scroll
I'm not using pfsense right now
because it runs on h/w that cant accelerate things with asics
basically high bandwidth usage makes the cpu 100% because packets are processed there
mine has an i5 and 4 gb of ram so i guess its good
yeah probably, dunno
but dont worry, cant make it work
asic is like a secondary CPU whose only purpose is to do packets
does it work @rocky badge
so its fast as hell
When GPU drivers reset
Looking for someone that want to share me its pfsense setup config. Im desperate
Yes
i thought pfsense was basically plug and play
Not really XD
if i can access, i get the internet icon with the triangle
i think some dns things are not set up properly
you get DHCP?
yeah, i get an ip and sometimes i manage to access the gui
"sometimes"
yeah
sounds like an IP conflict or something
i put the gateway ip but 1 out of 10 times it works
most important thing, i dont get internet
rule it out by putting your computer directly into the LAN port of the PFsense
see if the gui works 100%
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
@waxen scroll @clear igloo still having issues :/ http://www.speedtest.net/result/7414609779.png
Did you try crying onto the modem?
lol, the modem lives off of your tears though
And Charter will replace it with router and modem combo
wow i actually had to laugh at that
Which will become a WiFi AP
seems like a futurama joke
Hey hey @waxen scroll guess what
192.168.1.120 is unreachable
that's the gateway ip sooo no web gui
thats directly plugged into it huh?
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
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
whats arp -a say?
also it says your DNS server is 1.1
that could be a problem too
well everything adds up, so idk maybe your install is just borked if you cant access the GUI by IP
I mean I get confused, as dns ip, should I put the one of the main modem/router or the wan one
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
so nuke the box and start over maybe
Fresh reinstall?
yes
Or throw it out the window
window unless you really want to try it
Hahahaha
so, just to clarify: as dns server I have to put the wan ip right? In that case 192.168.1.62
Wait a minute
If I unplug the wan cable I can access the gui
oh jesus theres your issue
linux doesnt handle two interfaces in the same subnet well
Ffs
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
it kind of is, its not built to do the way you want though without more planning
you can... on the WAN side only
....
you're using two routers right? one of them holds your internet, one of them is pfsense
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
what did you change it to
16
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
dunno if you need to change that seperate
Put lan on 192.168.1.120/24, the pc gets the 255.255.255.0 gui works with wan unplugged
linux acts crazy with two interfaces in the same subnet and you just proved that
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
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
same problem.... return traffic uses a different interface and things dont work
Thanks pfsense ๐
@clear igloo today you learned
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
How is it possible that pf sense didn't fix something that important
idk, no same subnet on two interfaces is a pretty basic thing
Not for me
if you try it on a cisco router, the software will tell you no
Cisco is smart
Restarting the modem?
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
Does it come back normal if you stop charter
So you tell the enterprise What to install in their network?
@waxen scroll lol that seems fun
i do, yes
i design it, write the configurations, then deploy it
yep. got slaves for cabling and racking, then slaves for monitoring it for problems and correcting them
Hahahahah
if i cause a network outage it will be in the news
Cant you be a network engineer and the one that does thecl cabling/racking
thats how big the place is i work for
Wow
yes, at smaller business the network engineer does all of it
๐ค
bigger than amazon
Netflix xd?
Is it about e commerce
Lol
reboot ur internet
I did @waxen scroll
Does it get better if you stop the download @rocky badge
next step up for me is architect
thats where you purely make plans, no designs. you tell someone else to design it
i used to, not anymore
no, cameras arent allowed
those places are boring
why
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
nothing exciting about that
im not saying where i work lol
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
lol
they have slides in the office
empty
lol
its not you just cant see into the cages
@clear igloo I wanna kill Charter, my modem, and my router XD
A) Who wouldn't want to kill Charter?
They're crap ๐
at first i would say that seems like the cooling room
uses laser vision I see the gear
XD
?
they're not going to have many pics of actual racks online because customers dont like pictures of their shit on the internet
@ancient vigil on the left side theres something black
seems a piece of rack ๐ค
yeah
so there are servers
it is yes
those empty cages makes me think about wasted space
its where multiple internet providers hook up
so the internet providers exchange traffic between them in that facility
probably? if the italy ISPs want a united states presence
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
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
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
cant reach 0 ms even between my pc and the router
tcp traffic and udp traffic can do it
about having 1 ms of ping between the pc and the router?
eyyyy someone else that uses 192.168.
so ICMP needs to be processed by the routers CPU and thats less important traffic than other types
so it can be over 1ms
10.0.0.0/8 tyvm
lol
fight me
EYYY
lol
mmm whats that TTL in the ping test
come at me
Unless you have a dumb switch, at which point.....
Broadcast storm!
lol
I'll broadcast my storm all over your switch ๐
Spanning tree loop, sorry
^
an unmanaged switch
the cisco one once shut off a port cause of that i think
๐ญ
or for ppl like me COUGH
i have a good piece of equipment that i dunno how to use
sooo, unmanaged switches FTW
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?
So, you want to hear a funny @waxen scroll
oh theres linus online
Fortnite, owned by Epic Games, is in Cary NC (where I live) and there is ALSO a Fortnite Brewing, in Cary, NC
Guess who gets the angry gamer calls @waxen scroll
ROFL no way
lol
@subtle glen im not sure the question?
Every time the servers are down, they get hate filled teenagers flooding their voicemail xD
@waxen scroll you said that isp's use you company to connect to the backbone right?
or something similar
no they cant connect themselves
It's called an interconnect, they need to connect to each other somewhere
they need to rent space and pay for an interconnect
BGP, the lifeblood of the internet ๐
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
no like between isp and isp
You'd create a full mesh network, that's expensive and time consuming
one company i worked for deprioritized ICMP so it would add like 20ms
gamers hated it
definition of the year would say
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
ill take my inflatable toy boat and ill lay my cable
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
i think this one gives you more space about what you want
danger i did guess the company right? ๐
no
not even the one i sent in private?
no
no, i said i used to work in there
the thing he said is that if they shut down stuff they will be on newspaper
what could it be
i do design and implementation. troubleshooting is maybe 5% of my job
did i guess now?
no
@ancient vigil india mostly does the troubleshooting and monitoring
no more level 1/2 american noc jobs
keep disappearing
yes
LOL
the company is in america right?
why arent you working for one then?
cause im 16
no
and i cant configure a switch
well its time to do the CCNA then
oh god
ive only ever been a CCNA and look where i am
aint ready
you dont get hired for having a CCNA anymore
just imagine working at those exchange points: running in the servers hallway surrounded by cables maybe with Happy together -the turtles
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
so uhhhh, where do you start xD?
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
ive done cisco and extreme
some juniper but not enough to really mention it
@subtle glen A GRE tunnel connecting two remote locations over the Internet supports encapsulation of dynamic routing protocols. TRUE or FALSE?
what if im the CEO of cisco
CEOs are non-technical
ct what?
@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] ?
they're easy for people with job experience
AS Routing Policy
fuck
honestly the test is 10x harder than this
ok ok another question
im just getting bad sample questions from cisco online
What wireless standard do autonomous vehicles use to communicate?
@subtle glen that looks like a nice bridge
sure
no latency wit htose
those
yeah, hook up vehicles with those
remember kids: DHCP is everywhere
you are discussing about Networking FUndamentals??
Official Academic COurse???
you could also go static ๐
nah
all manual
we arent lazy
a what
xD
i dont speak lurick's language
That's the point
speaking lurick's language?
I made a bad pun ๐
about networking?
I'll take a /20
/24
oh heres a good question
go for it
@subtle glen why would i manage a router using a /32 on a loopback interface instead of anything else
sure
๐
tf is a loopback interface

i got this
is loopback even in CCNA? i dont remember
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
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
^
you use redundancy
a /32 on a loopback interface can be accessed using any interface on the router
If you remember to redistribute it to your routing protocol
XD
๐
192.168
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?
do i have to answer
yes
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
D
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
I concur, networking is hard but it's fun and rewarding too if you have the passion for it
A sounds tempting too
XD
๐
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
That has been Networking 303, tune in next week as we explore the wonderous world of MPLS!
how do you stay updated when new things come out
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
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
That's another way
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
let me know how it goes
give me an office and some switches
nope.
you change pools on the router ports and change subnets
thanks lurick, now i know the pool thing
@rocky badge show us a visio of your network
I don't have MS visio ;-;
XD
i'd die if work didnt buy me visio
My school doesn't buy us visio because we don't need it lol
did you draw your network diagram?
microsoft products for schools are free or heavily discounted, so i dont know why they dont have visio
ouch
Luckily I have my own Azure AD ๐
It thinks its a "work" account
@waxen scroll ok, downloading visio
how
no pls
dlink
@waxen scroll still installing ._.
dafuq
its almost time to go drinking
please stay
@clear igloo jack and cokes + shots of patron alllll night
Nice
Not a fan of coke but the patron I'll do
there are a lot of heatsinks in here
opening the product voids the warranty!
