I doubt juniper has nonstandard console ports
their own documentation matches the RS232 spec
waxen scroll
cisco is technically the non-standard one
tame carbon
really?
waxen scroll
people have been updating to follow them over the years
thats why its split weirdly between manuf

brilliant
@waxen scroll I also managed to communicate with an old 3com switch using the ftdi breakout I used for my stm32 development
but the breadboard setup next to a switch ,is jank

@waxen scroll Got pulled into a vendor meet with a remote company where they purchased softphones and are experiencing call drops. Had a walk the MSP through their FW and rules, god damn Sophos is horrible when it comes to configuration. Plz take over for me
waxen scroll
you went the distance
i would have been like yeah L3 is good. you get packets. ticket closed
hollow marlin
I was brought in because the MSP wasn't verse in in routing/SIP. Unfortunately I still get pulled into SIP issues
waxen scroll
MSP shouldnt manage what they dont know

nybody here good with networks and IPV6?
Ran into an issue the other day putting up a VPN and now my IP when searched and on cloudflare forums is stuck on the VPN IP....
which is the temp IPV6 line....for whatever reason
doesn't seem natural since I uninstalled the virtual network adapter and the temp IPV6 line is blocking me from accessing cloudflare forum networks.....

@hollow marlin man. blobs been quiet since yesterdays rant
hollow marlin
someone possibly did something they shouldn't have been doing.
Blob's ISP NOC alert
%PM-SP-4-ERR_DISABLE: bpduguard error detected on Gi4/1, putting Gi4/1 in err-disable state
waxen scroll
lmao
i dunno how GPON works but my assumption is that if he does, it will knock out everyone on his segment
the GW at the ISP is the one in the spanning tree wireshark
its not the ONT
i really want him to start sending priority 0 frames to his ISP
since the ISP is running default my assumption is they're just filtering BPDUs
otherwise they should have had issues already?
hollow marlin
GPON still views all ONTs as separate interfaces even though they are fed from a single fiber (PON). If BPDU guard is enabled on the PON interface it will be put in err-disabled and the only thing that happens is the TDM slot goes dark.
Each of the 64 ONTs are defined timeslots depending of pre-configured bandwidth profiles.
That assumes they did not disable the default BPDU guard as Calix blades do not have BPDU filter

somone recommend me an iperf server to test on so I can saturate fully,
peak cloak
unless you are running a server or that's for a company that connection is so overkill
public iperf servers suck

@waxen scroll you know school exists, right?
and I have to go to school and study at home?
So I'm not on Discord 24/7
hollow marlin
lmao
@onyx mango If you want to saturate 10G iperf on Windows you'll be wasting your time. It requires tweaking and even then Window's TCP/IP stack struggles
little schooner
@hollow marlin yes
rocky badge
yup
Then getting 10 gig SMB 😩, iSCSI tho
this is after fighting with Windows Server and FreeNAS for Samba/SMB then saying "screw it, I'm gonna try Ubuntu"
iSCSI though, Windows Server host and Windows 10 client https://blob.pcmr.rocks/LowSturdyBlob.png

How can I share a folder on a Linux Server without Samba?
I don’t want to use things like freenas or something because I need to do other things on that server.

Or maybe rsync the folders between the 2 systems. You'll basically have replication.

shy fern
can anyone suggest me a modem?
the one i have is pretty old and i think it's time for an upgrade
plain siren
DOCSIS?
plain siren
What feeds your drop though? Coax, Phone Line, Fiber
Need to figure out what kinda modem were dealing with
shy fern
got one of those cables that goes in some kind of adaptor and then into the modem
so i guess fiber?
shy fern
yes
shy fern
100% u don't know about the provider lol
i'm not from US
how does the name matter tho
plain siren
Well I ask because I need to see what kinda encryption if any they are using between modem and PON
solemn ermine
Question :
What happens if I connect to an HTTPS Proxy and connect to a VPN at the same time? (I have been doing that but I don't know if it changes a thing)
Would there be any difference, am I wasting time, I don't know.
plain siren
For example
AT&T uses EAP 802.1X Auth over VLAN 0 between Modem and that Fiber Box
To try to force the modem
Telus in Canada doesnt do shit
@solemn ermine You will route through VPN first
Then from the VPN Exit
shy fern
it is called moldtelecom
plain siren
You will hit the SOCKS Proxy
thick minnow
we need RGB routers 
plain siren
Congrats
thick minnow
*watercooled rgb routers
plain siren
They dont do any fancy shit between pon and modem
so in this case, it isnt a modem, just a router.
You can yank out the old one and replace it
Seems like they serve DHCP over the PON to give you your IP too. How nice.
So thats easy
How much sq ft are you trying to cover?
shy fern
what is sq ft
plain siren
Square Feet, sorry american. Size of house
thick minnow
I hate my ISP... they blocking users of changing the LAN network 
thats so stupid
plain siren
Give rough estimate if you have to
charred meadow
Square meters for you
shy fern
i connect it to my room through ethernet anyway but downstairs i want it to cover 20-30 meters
well
that might be a bit much
but at least 15-20
plain siren
If the WiFi AP/Router is on a second story, it usually does good job with whats under it
60-90 ft is not a bit much of an ask either
Reasonable
shy fern
the thing is that
i want it to reach far bc there is a huge wall between the router room and the living room
the main one of the house
it is like
shy fern
50cm wide
plain siren
and empty in middle
plain siren
Is it concrete/stucco or some material like that
fuck
Instead of one beefy WiFi AP/Router, you may be better off with 2 mid tier. One on each side
shy fern
it will be a pain to get a cable to the other side
plain siren
And you can do Roaming (Match the SSID's) which lets you just waltz over and connect to new AP without fuckery
oh well if there is no cable either
eh
Honestly I can give a "best shot" option but nothing guaranteed with solid walls
idk if you wanna sit on it and think or just take a look at what suggestions are avail
https://www.amazon.com/TP-Link-AC1750-Smart-WiFi-Router/dp/B079JD7F7G
Cheap and Effective, the TP-Link Archer series of Routers/AP's has always been strong and they keep to the standards well. Dont let its cheap price fool you, its strong for what it is.
https://www.amazon.com/Linksys-Dual-Band-Max-Stream-MU-MIMO-Wireless/dp/B01JOXW58I
Coming right behind is this guy, although it sometimes overheats, add a fan or keep it in a cool spot and it does just as well.
Both of these do what they say on the tin and up to their written specs.
Protip: Try to keep the Antennas Straight up. Since both only have 3, we dont need to set any to Horizontal for Horizontal signal alignment. Making them at like 30 degrees plays with signal rotation and effectiveness.
shy fern
i don't like the idea of overheating for routers...
shy fern
so uh
plain siren
taking a 120mm fan for example and sticking it on top does wonders at times
shy fern
does the second one get more heat than the first?
plain siren
Yes
I havent had an Archer series overheat on me. Ive pushed many of them to their limit
Linksys gets a bit toasty
shy fern
i have a very old tp link modem rn
wouldn't be surprised if by searching it up i'd find it's from 2010 or some shit
plain siren
If the Archer cant do what you want it to in terms of material penetration, honestly nothing will. No amount of extra antennas or fancy shit on those fancy routers help in this regards.
TP-Link TD Series or some shit
when I was looking up the ISP
shy fern
what's ZTE
plain siren
Dont ask
shy fern
well i can't complain about my ISP
i get 100 mbps download and upload and 2-3 ping on speedtest
plain siren
I wouldnt. They let you just yeet old router and swap them out without headache
Yeah that dinky D-Link aint gonna do shit.
shy fern
for 10$ a month
plain siren
Oh thats nice
shy fern
thanks for the help!
tame carbon
windows by default, doesnt reply to ICMP ping
why
It does reply when asked what MAC it has
tame carbon
@peak cloak maybe its trying to hide itself
but that is stupid, considering that ARP is a nessesary evil
hollow marlin
Windows has always done that. The firewall by default will not allow anything in, as it should. ARP is not apart of windows but instead handled by the NIC
plain siren
The ARP Table is stored on windows. Each nic has its own ARP Table too.
The protocol itself on most modern nic's is normally offloaded
Example of a dump from winshit. Can easily be done
arp -d to flush the windows arp cache
tame carbon
mhmm, I know dear
Its a bit unrelated, but trying to get interhost communication in a VM
windows however, even though it is set as a home network, refuses to accept incoming connections from 192.168.192.0/24
waxen scroll
what do the packets say
little schooner
@tame carbon getting nested kali under ubuntu under ubuntu to communicate was also a battle I didnt have time to solve
Instead I worked on my leadership project and felt accomplished
little schooner
It is, especially when they have to be isolated instances too
Need like hundreds of vlans or Something
The easy way would be to not nest them
plain siren
Basically becomes nested NAT
Honestly, I am hard pressed to see any modern day reason to Nest Virtualization anymore (Besides Containers, but ignore that for now)
Most likely though, you need to enable in the first VM (not the nested one), various non-default configs for that to work out. IP Forward for example in sysctl.
onyx mango
@peak cloak Its a gaming line here in Tokyo, I upload qll my recorded vids to my office and files are typically 4TB per 20hr live stream, it is not Overkill for my use case. I also game with a lot of friends on West US server and on normal 1gbps best effort ipv6 fibre my ping is trash, on my 10gs line it's under 100ms and way mpre stable, so at under 65USD per month, is pretty damn reasonable considering I used to pay 3600USD per month for corporate 10gbps. It'll be upgraded to 20gbps or Nuro 20GS pretty soon, doesn't mean I can get 20gbps on 1 pc, it is dual 10gbps from 1 simple modem and I can dedicate 10gbps per pc, one for gaming and one for live streaming and virtually never get hiccups. Nuro 20Ggbps gaming line is only 72USD per month.
onyx mango
you don't even know, xd
plain siren
I am an ISP for my Neighborhood. Im paying for 6x 100Gbit Dark Fiber lines
onyx mango
lol
plain siren
and the AS.... and IP Transit... and some Peers....
ugh
Im basically robbing the school in comparison for their 10Gbit too
hahaha
Both schools actually
Thanks government.
onyx mango
wow
hollow marlin
6x100. How cute
spark wigeon
How much does that cost per month and where is this?
waxen scroll
@hollow marlin thats your first reaction?
mine was no redundancy and no OOB management
hollow marlin
Shhhhhhh
waxen scroll
once school discovers packet fabric, its all over
plain siren
Well this is one of 3 routers
there is redundancy
out the ass cuz I got more money than sense
How much does that cost per month and where is this?
@spark wigeon total cost for Ops is running around 187K/mth
But out of pocket I am paying like... 1.9K/mthish after paid up with net
so for me 1.9K/mth for my own DF line is nice
Its in Texas. Houston area
little schooner
All im asking from my isp in terms of speeds is at least 25 mbps upload. I dont understand why its so much to ask for from concast
hollow marlin
Why are you paying almost 2k/month for a dark fiber line to your home?
plain siren
Because I literally can
little schooner
concast illegally put me into a contract when I signed up with no contract @waxen scroll
how can they even do that?
plain siren
And it turned my neighborhood into a huge homelab
Did they negotiate with like HOA or some shit?
hollow marlin
Just because you can doesn;t mean you should
plain siren
Well true. But I did anyways.
little schooner
@hollow marlin hmm that statement would of helped me to convince the prof not to require nested vms
hollow marlin
We get it, you have a lot of money. Its even in your avatar
little schooner
it was requirement yeah
plain siren
@hollow marlin I aint saying it like that
Im just saying cuz you asked
also > requirement
but why?
little schooner
well it was an idea he saw on the internet somewhere
plain siren
oh no
little schooner
and he wanted to try it out in a lab
but he asks me to do it
It only took a day to get it setup sorta alright
plain siren
Yikes
little schooner
it was 100GB and then 41GB after compression and resizing the vhd
not too bad
I set it up on my 905p ssd so it was fine

Building to Building Bridge, Fiber, 802.11ay Solutions....
south blade
Fiber huh, what kinda hardware does that need.
peak cloak

@south blade well, it would literally be running a cable underground or in the air to the other site
plain siren
I hate unifi but I am going to show it as an example:
https://store.ui.com/collections/unifi-network-routing-switching/products/unifi-building-to-building-bridge
south blade
I was looking at some of the Ubiquiti stuff but not sure what's the minimum to get his 1Gbps he pays for across.
peak cloak
little schooner
point to point is out of the question then for 1gbps
it doesn't do it that fast with unifi equipment
plain siren
That PtP Bridge can do 1.2 Gbit/s on a very very very very damn good day. Any bit of rain
hahahaha
it dies
plain siren
Gotta test the fiber cable but dont have anything on the other side?
They work like a charm
south blade
Hmmmm, and fiber comes in 600ft lengths?
peak cloak
Just need to terminate it yourself
south blade
Right now he has a coax he tried, must have gotten kinked or something cause it stopped working. xD
plain siren
oof
A decent coax testing kit should find faults and how far down the line they are
Or perhaps it was too long
Either way, having an issue keeping coax from kinking.... fiber is gonna be a pain then
haha
hollow marlin
Fiber is actually pretty robust
south blade
hmmm
plain siren
Unless you are clumsy af like me and step on a cable D:::::
south blade
If the dirt is sandy, it should be safe?
peak cloak
for direct burial you can get an armored cable, it should be fine
plain siren
^
hollow marlin
@south blade The only thing you really need to worry about when burying is 1. CALL DIGSAFE, 2. Make sure its its deep enough where if the ground freezes it will not get crushed
waxen scroll
i want to trench my yard with a machine at some point and i cant wait to get near power lines. better mark it correctly ;p
hollow marlin
Cannot count the number of times its been flagged and we hit another line
Worst was it was flagged and marked and the construction crew thought the markings we "dig here". Then we lost our west link
waxen scroll
i want to put irrigation in and power/coax is going diagonal across my lawn, so ill get near multiple times
south blade
Well, if I just follow the coax line it should be safe though right? >_> He did this to avoid the $2,000 the ISP wanted to drop a line to his house, so ran a line from the inlaws house they aren't using to his he had built.
plain siren
Why not try to fix that coax?
south blade
Well, he wasn't getting that great a speed on it to begin with, not sure if it was because of the length or it was already damaged right from the get go.
plain siren
Or the right coax
south blade
Not sure what path he followed but if he tried to go as direct as possible it seems like it should have been around 400 feet, but he might have bought 500ft maybe.
Giving up on 1Gbps, this should be able to do it? https://www.amazon.com/NanoBeam-NBE-5AC-Gen2-US-airMAX-Dedicated-Management/dp/B07NNWY9Y8/ref=sr_1_2?dchild=1&keywords=nanobeam+ac&qid=1600287730&sr=8-2 Nephews got home schooling now so need to get online.

peak cloak
basically
make sure to the right SFP module though
I'm positive this https://www.fs.com/products/29851.html
will work with this https://www.fs.com/products/100957.html
that SFP module is for Single mode fiber
idk much about the difference between Single-Mode and Multi-Mode
south blade
I know nothing about fiber, these supposed to be the ends huh?
clear igloo
LC/SC are the ends
Single and Multi are the type of light mode that can pass through
multi mode is limited to around 300-500m and single mode, depending on the SFP used, can be 10s or 100s of kilometers
south blade
I'ma have to Youtube how this is setup cause I can't imagine I can just use some nail clippers to cut fiber LOL Edit: Also strugging to find a clear answer on what single vs multi is supposed to mean, is it a speed limit, or just distance limit, or something else?
clear igloo
No you cannot, if you know how long it is you can usually buy it pre-terminated which is FAR easier than getting a kit to terminate your own fiber
peak cloak
south blade
_> Uh, $1/foot?
south blade
This is seeming very expensive to try when I've never worked with fiber. LOL
peak cloak
yeah, normal fiber is cheaper
clear igloo
peak cloak
hmm, also armoured
I don't think that type is meant for direct burial though
it'll work, just idk how long it'll last
clear igloo
You could toss it in some PVC pipe to be extra safe
south blade
Hmmm, gonna have to talk to my brother, cause even trying that to see how long it lasts is basically the same price as the Nanobeams.
peak cloak
fiber could do gigabit, probably a lot more
clear igloo
If you need reliability and cannot tolerate bandwidth fluctuations then fiber, otherwise the nano-beams would be fine
fiber can do MUCH more than gigabit given the right transceivers 🙂
clear igloo
lol, yah it's nice 🙂
south blade
$80 shipping for custom length of 150 meters of it from Asia Warehouse -_-
clear igloo
ooof, I missed that
south blade
Doesn't look like they customize anything from a US warehouse lol
I even tried 32 meters and it has to come from Asia
Only $24 shipping for that though, how much does fiber weigh that it almost quadruples the shipping for the length I would need? xD

peak cloak
all-in-one I assume

you should be sizing for connection speed and not house. if your house is 2500sqft + you will want access point(s)

i see thanks guys
waxen scroll
evenly. its whoever gets there first assuming no interference
plain siren
MU-MIMO
Thats how WiFi splits the communication between multiple devices
There is a reason why we say: dont use the middle bands on your wifi
Cuz routers are designed to take turns with each other. Even if its a diff network but interfering nearby. You sit between bands, you just cause noise.
Good luck finding a WiFi AP without MU-MIMO
But thats not how you would gauge speed estimates here
So you have multiple things to consider
Location, Walls/Obstacles, Uplink
and amount of Clients
Your Router is really an All in One
which does: Switch, WiFi AP, Firewall, Modem, and Gateway
packed into one box
Well I am speaking generically, thats usually how ISP's handle it.
yeah modem is starting to finally dissapear
With Fiber and the use of NGPON and GPON, etc
XGPON... whatever the other names are gonna be on top
It takes turns
I talk to you first, move over to next guy
talk
move over
talk
then come back around
Although its actually a bit more complex
yeah I discribed MIMO tbh
MU-MIMO is uh
Now were gonna have some radio theory fun
That being said, An Archer C7/T7 Series WiFi AP/Router from TP-Link will give you well over 100 Mbit/s for like 15 devices
and its dirt cheap
unless you got things like walls to consider
another infographic I have to send you on your way
describes the queue system in a simple visual manner
Its hard enough getting WiFi balanced, its amazing our cell towers still work considering

Buy a network switch with enough ports for all the ports on that patch panel + one extra for your router. Based on the number of ports on the patch panel (and assuming your router has 4 already, you can probably make do with a 16 port gigabit switch @thick minnow .

back in the day, they used to preinstall the wiring and security sensors for your home for free, , and hopes to mkae their money back with your subscription

You can get a couple actually
peak cloak
I need to pay to renew next year
tame carbon
You can get a free AWS micro box too
all you need is a credit card, to start a free trial
you get a 1 year vps (micro tier)
peak cloak
yeah, I have a .tech
plain siren
Netwise offers 1 year of free Colo too
tame carbon
I use this myself
You can integrate it into software, and it tracks errors and freqency of errors
then can also collect context, to help debugging
plain siren
Check this out too: https://www.fluentd.org/
Itll aggregate loads of log sources (sentry included) and let you export into one
tame carbon
@plain siren is that to just snoop all /var/log and more ?
tame carbon
lol, I love their page on why one should use fluentd
plain siren
Its basically an export collector that bundles it all up and lets you centralize the output into your choice of system
tame carbon
plain siren
They aint wrong
tame carbon
Can it group the various logs from services, by events/messages or quests?
tame carbon
damn
plain siren
Yuh
tame carbon
Oh, and I like this
they have a minimalist version for embedded applications
neat, I will remember this
plain siren
They are CNCF Approved and almost graduated, it has lots of backing despite the looks
Lots and lots of fun projects...
tame carbon
I wish my education focussed more on middleware
they did tons of languages, design and conceptual ideas
like architectural design
but we never got into the grit, of actually implementing things like a load balancer
plain siren
Heh I literally just got out of that Industry
tame carbon
Things like redis to remove state from your instances, so you can scale
plain siren
https://tikv.org/ or even better....
tame carbon
they teach us the "stateless programming"
plain siren
Yeah I know
Alot of people I interview know concepts
but they dont know the work
It made it hard to find workers
tame carbon
I tend to teach myself this stuff
plain siren
Yeah you have to.
plain siren
I give free classes as much as i can
tame carbon
wait, let me find an old deployment diagram
plain siren
Just to supplement these terrible education systems
plain siren
Problem is, the industry is now running faster than ever
tame carbon
plain siren
its easy to lose grasp and sight of big picture of industry
tame carbon
this is from like 3 years ago
plain siren
Omg thats those ASCII Diagrams you can render pragmatically
tame carbon
UML
plain siren
YUS
Yeah using a minecraft server as a "Public Facing Load" excuse just to do this
Damn reminds me of 7 years ago ahahahah
tame carbon
well, not per say load balancing
but chat
and profile synchronization (if players go to other world)
was handled through redis
plain siren
I did it through MariaDB
tame carbon
I used sql for persistence
tame carbon
during my last school project, we worked with 25 students on 1 project
that was hell.
project was completely written in java
and was ment to be a ride sharing service
using school's lesson schedule
plain siren
Here hold on
ima give you a massive list to toy with
2 mins
Look through all of those
This is basically the tool chains running the show rn
plain siren
I hope
plain siren
Its got it all
https://longhorn.io/ I use this personally for my own shit too
This is a fun one
plain siren
Bingo
You can mix and match all damn day
That list is always updated and it covers the industry
https://landscape.cncf.io/ < Without Card Mode Link
tame carbon
@plain siren one time, we had courses on embedded development
and our teacher, die hard windows guy
plain siren
~groan
tame carbon
after doing daily slides, went back to his desk
with his laptop still on the beamer, installing windows 10 IoT core on his raspberry pi
plain siren
vomit
tame carbon
I went over, asked him: oh cool, so we can do .NET stuff on raspberry pi?
"What kernel does it run?"
who cares
facepalm
was quite funny, seeing him deal with it
apparently, the setup of IoT core, requires a laptop with wifi support
after flashing the sd card, you have to connect to its own wifi network, to finish the setup
plain siren
There is a reason why there is no build for RasPi v3
plain siren
They cant even keep mainline windows afloat anymore
I have 118 emails rn
thanks to todays CU
tame carbon
Don't make me distract you from your work <3
plain siren
Oh trust me I cant do shit
M$ just yeeted some stuff that broke tons of production equipment
My response was
¯_(ツ)_/¯
tame carbon
oh, what's your preffered CI tool?
plain siren
GitLab's CI
tame carbon
My work uses bamboo
I used GItlab privately for that minecraft server, for many years
plain siren
I have licensed GitLab Enterprise.
tame carbon
but gitlab so much bloat, it cant even run on 2 cores properly anymore
plain siren
This is true
tame carbon
Moved over to gitea + jenkins
tame carbon
works for java projects
tame carbon
When I first started off doing config migrations, I used to build this into the software
plain siren
Oh dont use CI for your config.... we built entire toolchains just for that too
peak cloak
@tame carbon I'm new to all this why did you use redis for in Minecraft
plain siren
tame carbon
@peak cloak we ran multiple minecraft servers (each world had its own core)
behind a single public gateway
so users see 1 server
chat, profiles and anything else, was synchronized over redis
peak cloak
ah
tame carbon
PubSub and hashes
plain siren
Now we have proper tools for that too
peak cloak
and a proxy like waterfall?
tame carbon
bungee
peak cloak
yeah
tame carbon
peak cloak
waterfall is a fork of bungee
peak cloak
yeah, I use papermc for mine
tame carbon
we run paper now too yeah
plain siren
Heres a leg puller for you
tame carbon
not sure why, but someone else made decision
plain siren
NGINX Can proxy Minecraft
peak cloak
it's just a small SMP for friends
tame carbon
NGINX ?
plain siren
EYUP
tame carbon
since when is minecraft TCP
plain siren
https://github.com/haveachin/infrared Someone figured it out then everyone built a whole new fucking bungeecord

@plain siren oh damn, that thing has one feature..
that I kinda want
idle placeholder
currently
we used a 512MB void world server, to hold the player inbetween saves when moving to another server
this is kinda because of the 'legacy' from the saving machanism
that whole project is about 20k lines of code at this point
plain siren
https://github.com/feather-rs/feather Heres another fun one
tame carbon
hah.
plain siren
yeah ik
tame carbon
Yeah there's been native implementations of that for a while
how else do you explain TheHive
with 30k players online
plain siren
I forget who it was like 9 years ago
I did my first scaling project with them then they got sponsored or some shit by cloudflare
fuck
tame carbon
@plain siren we also have 'Quidditch'
like in harry potter
but that server runs at double the tickrate
so to make the minigame more playable
high speed flying, with low tps (20) makes things jump a lot
plain siren
https://github.com/thekeenant/cloudflare-mc While it aint updated, you might find this useful
tame carbon
lmao
tame carbon
I signed up very early on, for the beta program of OVH's "gaming servers"
they offered layer 7 filtering for minecraft
plain siren
Yeah dont buy anything from them rn
I say that because they are my new employers
and I am about to tear down the entire network
tame carbon
4.2GHz clocked machines with network that can't be kicked offline
used to have little squeekers with booters
who if they didnt get their way, tried to hold us hostage.
plain siren
2 months ago, I disabled/canceled/cut off about 2000 Spammers, Bots, Brute Forcers, Scanners, and Traffic Gens (For booters)
tame carbon
not the smartest of the bunch, because we tracked his username to a server of his own, which also exposed his real address
tame carbon
found his address in public phonebook, called up the guys.. MOM
plain siren
All at once too
tame carbon
xD
plain siren
Ive had my fair share of drama in the MC community
tame carbon
told them, I would go to police if they didnt cease their attack
plain siren
Some guy threatened me
turns out he had GPS Monitor
So I called his Probation Officer
plain siren
whoops
tame carbon
@plain siren when I first set up an IRC bouncer on OVH's network
I got an angry email from their admins
"Your box has been hacked"
No it hasn't.
tame carbon
for what?
plain siren
Incompetence
tame carbon
ah
tame carbon
were they long time employees?
tame carbon
at my first employer, most of the developers were 10 years experienced
but their formal education was things like technician and electrician
so when I came around, freshly steamed
saw 1000 things wrong with their process
worked there for 1.5 years until I left
plain siren
I told them what was gonna happen
They actually had the audacity to laugh at me
whoops
tame carbon
did the company hire you, to get their shit back in line?
plain siren
OVH is ...
tame carbon
you must be a good consultant...
tame carbon
My Software architecture teacher worked at IBM and Oracle previously
plain siren
OVH wanted me badly
tame carbon
but his ego, was so fucking big.
plain siren
I dont really do the ego thing
tame carbon
it was
microservices microservices microservices
like, dude. not every solution has to be "modern"
plain siren
tbh, I can really just point to my previous title and walk away now which is good enough for me
If its gonna be modern, be innovative about it atleast
tame carbon
we developed a backend, that you could tell which services to start
plain siren
and btw this doesnt fit in Active Dir
Sr Cloud Operations Engineering and Solutions Design, Senior Primary Solutions Architect and Engineer, Lead Core InfoSec Administrative Operations Engineer, Lead InfoSec Policy Architect and Compliance Officer, Senior Solutions Management and Service Delivery Expert, Core ISLP Network Engineer
tame carbon
like $ backend --services auth routing account
if a backend service, needed another service which wasn't hosted locally, it used an address to another instnace
plain siren
A CLI Based Service Control Framework
tame carbon
so you could run the whole stack in 1 process
plain siren
noice
tame carbon
ye
we won the "Couragous coding award"
but I didnt attend the ceremony
I was drunk and on the train home by that time
xD
plain siren
yeah.
tame carbon
I wanted to test this at some point
You can deploy many languages inside a common framework
and do cross-language integration of your code
plain siren
Wanna get even funkier?
tame carbon
well?
tame carbon
Argh
plain siren
This is how you get those containers with manifests that list all those archs
Its all done from this
tame carbon
I had to set up cross compiling for arm on a build server once
so confusing at first
wait
what
this thing virtualizes your build environment?
plain siren
Yup
plain siren
To emulate the arch.
You can also execute in said environments
like ARM Container on X86
run it
You familiar with Eclipses fancy ass cloud IDE?
plain siren
Its built on K8s
It builds your environment for you
to dev in
Then lets you pick your IDE of choice
And ofc does your CI, Debugging, Tracing...
tame carbon
plain siren
They said Moores law is dead.
I said containers happened.
It never died, just changed forms.
plain siren
You think?
GeForce Now was basically alluding to the future right there.
We took gaming with us along for the ride
tame carbon
software architecture needs to be reviewed, and more tightly integrated with the hardare
plain siren
Other way around
tame carbon
major performance gains are only really in ASIC logic
plain siren
We are abstracting the hardware
tame carbon
that is cool
plain siren
its the secret to AWS
plain siren
Those "VM"s on AWS are not VM's
Now heres a little food for thought
What if I wanted to use the RAM in machine #3
the SSD in #8
and the CPU in #16
plain siren
Not alone
but it does move around
AWS has a private little project going on
They ARE abstracting the hardware
its too late
its happened.
tame carbon
hardware is faulty anyway
plain siren
Multi-Tbit Core Fabrics with latency as low as 0.002ms
tame carbon
yeah okay
if your wallet has infinite cash
I guess you can go all the way, and redesign your entire physical layout
plain siren
Well... Amazon did just that
plain siren
Yeah
plain siren
might as well call an AWS Datacenter one big ass supercomputer
192 Million USD in R&D Later
tame carbon
year 2038 bug, will cause all compilers on every system to delete itself
then we back where we started
plain siren
Ever seen this?
Container or VM, its all treated the same.
bare metal performance + the flexibility of virtualization
tame carbon
nice
plain siren
tame carbon
so baremetal virtualization
but with more special sauce
quite neat
I really need to some reading up on this
I had no idea there's that many cloud solutions for this now
plain siren
I showed you the surface
tame carbon
yeah, I can imagine
plain siren
You can dig the hole.
tame carbon
^^
headache subsiding, stomach still bit ngh
called in sick today
I was up 3 times last night
plain siren
I have yet to sleep
tame carbon
I dont really get sick
but idk why today
I had mcdonalds yesterday..
first time this year
was maybe a mistake
plain siren
pfft
