I'll try though
If we assume it's one VLAN per room, what would be the next step?
another classmate said they did one subnet per floor
topaz quarry
honestly you should go on youtube and look up Keith Barker
and watch his subnetting stuff
there's to many correct answers to this question
thorny geode
A classmate wants to know if 53 devices is too much for one switch
like would this be too much traffic for the first switch:
so the prof wrote back this:
"Hi,
We didn't discuss the concept of VLAN by now, and I didn't mention it anywhere in the project. This approach involves trunks that are nor discussed yet in our course.
So each subnet is on each floor, except for the first floor that has two subnets, Subnet 1, and Subnet 0 (please see in the Distributed Documents, the Advanced_Networks_Project_A_Boost_for_Students, fig.10).
Tomorrow between 2:00-4:00 pm we will approach again the topic of Team Project in much larger details. "
this is figure.10
plucky berry
anyone use cisco packet tracer?
topaz quarry
53 devices for one switch?
you mean 53 physical devices?
assume companies only have 48 port switches
you can run trillions of containers/VMs behind one switch
but only a certain number of physical hosts
thorny geode
one of the requirements was "The company has bought one router with 6 Fast Ethernet ports and you also may have any number of switches with 32 entries you might need." does the 32 entries imply 32 port switches?
peak cloak
that's what I would assume
waxen scroll
see? i knew you would get in trouble talking to me
thorny geode
haha it was worth verifying, so thanks for that
topaz quarry
they're referred to as interfaces for switches
so idk what entries means
physical interface <=> port

this is the assignment
@thorny geode
What do you do to get this fun homework?
peak cloak
that's not fun imo
old stuff that isn't really that relevant. The concepts though, yeah I understand what the prof is trying to teach
obsidian token
Oh well, yeah school is always behind ig
thorny geode
so the prof basically gave me most of the answers, that figure he gave us is basically the diagram we have to recreate (except we show the missing floors 2, 3 and 4)
peak cloak
ah ok, that's nice
hearty fulcrum
is there a way to connect to paired bluetooth devices without removing them from windows like you can on other oses?
waxen scroll
why do you need to remove them
if the device supports multiple pairings it should be fine
hearty fulcrum
i have an xbox one controller with bluetooth
and it's connected to multiple devices
when i connect it to another device it'll look for the device it's currently paired to
so if i wanna pair it to my main pc again i have to remove it from the paired devices list
because i don't see an option to connect
hollow marlin
@waxen scroll the biggest crime about that assignment is still referring to classes
waxen scroll
@hollow marlin i guess
public IP. no NAT
no vlans
no access lists
the more you know, the more you'll fail that assignment
this is why i tell people like @little schooner you gotta be careful
hollow marlin
Yeah it looks like its just a routing assignment. I just wish they would give the mile high view on classes and never refer to them again.

@thorny vector Im trying to make good functioning CNC's & i also need to take information from my files like usernames , keys etc...
thorny vector
Well, are you going to import another library to use? Present data via an API? Or build your own sockets? The last one I do not recommend.
@tight fiber
tight fiber
@unborn sluice its actually for a underground selling website I have
tight fiber
@thorny vector I was planning on using libssh but idk if API's would be the best way to go
unborn sluice
CnC over ssh
thorny vector
Also, don't pull data from files. That's a great way for someone to find a remote code execution exploit.
Use a database of some kind
unborn sluice
I mean his implementation is shady enough
thorny vector
And API's are great. For example, vmware's vCenter use API over https for its C2
tight fiber
alright thank you also I have had problems in the past with people trying to exploit my C2/Cnc server what are some good libraries for C2/cnc development that are more secure then building your own sockets ? cause you implied that building your own sockets you "do not reccomend"
thorny vector
Yeah. That's for the upstream people to do. I don't develop on that level, when I do build its infrastructure building, so I never dig down into C of any variety too much, and when I do its edits not additions, so not sure what to recommend. I'd just look up popular REST API implementations for what you're trying to do.
How are you doing your developing?
tight fiber
ive mainly been using database layouts & incryption from NCSD & CIA.gov
& im pretty shit at devolping most of my projects go for months at a time all I do is scetch all my programs into google drive so I could use them on latter dates
thorny vector
I meant what development tools? Coding environment, compiler, target and host OS, etc.
tight fiber
I code mainly using parrot OS & debain WSL. my compiler I use is GCC & I use python for incrpytion. Also i dont really want to reveale what im doing as that would probably get me banned
topaz quarry
are you trying to do basic network development?
is that the story or like what's the goal?
well
you see without your exact goal in mind
i probably can't help :/
thorny vector
I wouldn’t use python for encryption. If you’re already using C, do it natively
tight fiber
@topaz quarry im shit at socket programing but im trying to get more into network devolpement
topaz quarry
when people use a tool, it's for a reason
like when i use a toilet
it's because i want to take a dump
what are you trying to accomplish?
tight fiber
the incrpytion algarithm I use only works in python :/
thorny vector
I doubt that.
topaz quarry
didn't you know roaldi
algorithms only work in python
what are we doing
why are operating systems not implemented in python
tight fiber
XD the tool im making is an admin tool for my pre existing database im trying to make a program that allows me to backup logs read logs & write over them etc...
thorny vector
why are operating systems not implemented in python
@topaz quarry Not going to lie, that'd be dope to see how it was implemented.
tight fiber
the onyl problem im having with the program is the connection protocal for the hole thing
thorny vector
@tight fiber Yeah. Expose an API that interacts with the DB via your DB reader of choice
tight fiber
the incpytion algorithm I use work only in python its not impossible to use it in C & other laungues because it take 30X as long
topaz quarry
i mean idk why you're punishing yourself with C
thorny vector
If its taking longer in a lower level language, it's not being implemented correctly
topaz quarry
^
when python developers develop in C
bad things happen
spamming type erasure is so dumb
tight fiber
XD my incrpytion algorithm is used by the US gov
thorny vector
So? I work in the DoD, that doesn't mean anything
tight fiber
No but ive done my research
tight fiber
they dont use just one incrpytion algorithm
thorny vector
Okay. Then do more research, and find a better C implementation of the encryption algorithm you're using.
topaz quarry
^
thorny vector
And mah dude, we use what ever makes sense at the time
tight fiber
Im gonna stick with the algorithm I use just because ive been using it for years without any problems & no reverse enginering/hacking
topaz quarry
like anything that's accelerated by AES-NI will crush any python implementation
then do all of your stuff in python
since your favorite algorithm is in python
tight fiber
I hate python
thorny vector
Your first mistake is assuming that whatever you're using is perfect.
@topaz quarry We're agreeing on something, he11 is about to freeze over
topaz quarry
i know right
topaz quarry
bro the DoD is going through a freshening up time
thorny vector
Windows worked well for many years. Then eternal blue
topaz quarry
the old farts don't want to maintain their stuff anymore
because in 2020 it's becoming impossible
like i literally went to China Lake for a thing
and they asked me to do stuff in C++98/C++11
i literally said no :/
and they were like why
maintainability
making new projects in C will disuade people from joining you
your answers are Go, Rust, and C++17/C++20
tight fiber
alright lets say i decide to listen to you what would you reccomend to keep up ""MAINTAINABILITY""
topaz quarry
use languages which are both popular and have a strong future in the private sector
when the DoD forced cobal down everyone's throats
that thing had no lifetime, in fact it's sole purpose was to be a stop gap while bjarne figured out C++
your answers are Go, Rust, and C++17/20
tight fiber
most of the things that can be done in C++ can be done in C
topaz quarry
that's not true
constexpr cannot be done in C
templates cannot be used in C
that's basically 80% of what C++ is
do you realize that Dennis Ritchie started using C++ at the end
because C++ is literally C + 1
thorny vector
C is less secure than c++
topaz quarry
because of maintainability problems
it's not like C is inherently more insecure than C++
it's just it gets less eyes
less security audits for projects
security audits are expensive
not having templates and not having contexpr makes it much harder to write secure C code
you can't use units in C without dumping tons of memory at it
Dimensional Analysis is a necessary component of development that people just throw out the window
thorny vector
It is, actually. Since c++ is object oriented, you can hide variables in a class, and only provide a function interface. Strings are immutable in C++, and enumeration constants don't have any type safety in C.
tight fiber
I've been using C for quit a while ? why would I switch to C++ just because of security. C is a very common language & is one of the oldest languages known to man & it will probably be used for much more.
topaz quarry
because hiring people will be impossible
thorny vector
Using encyption to stay secure and private. Using C because you don't care about security.
topaz quarry
because unless you promise to live for a million years
thorny vector
topaz quarry
no one else is going to maintain it
unborn sluice
why are operating systems not implemented in python
lemme tell you a story
topaz quarry
cognitive load in C is much higher than C++
tight fiber
If I doing something on a more larger scale I would consider using C++ but C is better for the programs im making
topaz quarry
let the language do stuff for you, you don't have to use init and release paradigms
i mean do whatever makes you happy
but no one will take up the project
and you'll get minimal support in 2020 for it
like we're basically at a point where we use C++17/20 for systems development, Go for web, Rust for systems development, and python for IT tooling
tight fiber
I mainly Use C for implamentation to make the service I provide easy to maintain for me. I dont just use C for my service I also use golang & C#
topaz quarry
if you understand C, C++ is a billion times easier
unborn sluice
Just code your algorithms in asm smh

Yeah. Multiple bare metal hosts too. All on 2009 now

Yeah, epsecially with the current way cisco has its beacon liscenses
topaz quarry
like wtf cisco
thorny vector
They literally lost all of thier customers that have airgapped networks
topaz quarry
we agreed on something else
we're screwed now
lol routerOS and vyos are so much less complicated than cisco stuff anyway
tight fiber
I used to have a cisco router with dd-wrt on it & cisco fucked up my router because of an update so yee screw cisco
thorny vector
I think what our end goals are in terms of what we want our applications to do is what really separates us. I build smaller infrastructure we have to hand configure for each customer we go to, vs the automation and expandability you like to do.
topaz quarry
it's not just their liscensing though
like even just using their stuff
i don't want nested prompts
like broo
i believe in automated networks because i can just program them
vyos has like one of the best restful apis i've ever seen
as does opnsense
and routerOS the epeen op
tight fiber
cisco has shown they dont give a shit about there customers either with simple shodan searches it shows that their is more then 1000's of vulnerable SSH routers
thorny vector
I'd be open to moving our stuff to vyos. Unfortunately we do have other analysts that need to be able to hop into the firewall every now and then, and gui is just the best way to do stuff with minimal heartache
topaz quarry
if you want to give me a list of things you want in a gui
i'm making a web ui using C++
cause i'm fuck it
thorny vector
For vyos?
tight fiber
@thorny vector what should I use for receiving data from APIS in C (reddit recommends libcurl)
thorny vector
seems fine to me. Again, not a programmer. I usually only ever look at C if any flavor of I'm developing an exploit
topaz quarry
one thing to look out for
install the correct version of libcurl
or SSL won't work
:/
tight fiber
Ok why do i need C++ & python I just want to use C
topaz quarry
it's just python syntax
with C++
it's 100% C++
and it uses libcurl in the background for you
thorny vector
This is where we reference the above conversation we just had, and leave it at that.

if you go to www.libssh.org it says they offer API support is libssh good or would you prefer libcurl

libcurl4-gnutls-dev
libcurl4-openssl-dev
libcurl4-nss-dev
look up the differences
it actually matters
tight fiber
alright thank thank
thorny vector
@topaz quarry This is the last time I use one of my lower powered cpu hosts to compile stuff
tight fiber
so libcurl4-gnutls-dev is just for http not https

tight fiber
@topaz quarry thank thank
hollow marlin
In the tik just enabled DHCP-client on WAN, DHCP server, ND and off to the races
topaz quarry
so i can ping ipv6 addresses in the router
hollow marlin
Just make sure you drop in your v6 firewall rules though
topaz quarry
but it's not handing out anything
hollow marlin
Check to see if managed-address-configuration=yes under v6 ND
topaz quarry
so managed address configuration should be checked?
is it in assisted mode by default?
hollow marlin
Yeah its the flag that tells the client to pull DHCPv6. v6 relies heavily on what the flags say
tight fiber
im pretty sure you can set your IPV6 by Find what your IPV6 is through DNS mask and public IP then upload that IP USING "IPV6 = 2001:470:1f07:106c::1/128" to /etc/resolv.conf but you have to set your IPV4 too
thorny vector
I'm convinced I need to do a blood sacrifice to get my ISP to give me an ipv6

hollow marlin
I have almost my entire network v6. Still waiting on a budget to remove the last of the B6 blades that don't support it

do they really now

True that
tame carbon
@tight fiber you looking for IoT messaging solutions?
AMQP is preffered protocol for stuff like this
for low bandwidth devices, MQTT can be used to exchange data
I've used LoraWAN equipment before
RouterOS actually has support for lora now :p
tame carbon
@topaz quarry AMQP is used by more than just rabbitMQ
tame carbon
it uses very similair protocol
AMQP is just one of them
But I believe openAMQ is ded
I just use redis for pubsub stuff
dont need a big exchange
Only deployments of IoT that I've seen, were with LoraWAN, to a gateway that took messages from the air and sent them over IP with MQTT
Either commercial networks, or open networks like ThingsNetwork
topaz quarry
redis doesn't make promises about deliverability though
but yea it has a pub/sub function
so routerOS has support for lorawan somewhere?
in all the config panes?
tame carbon
They added it with a 6.x release I forget
my hardware doesnt have capabilities for it
topaz quarry
this is pretty sick
tame carbon
Every RouterBOARD with a miniPCI-e interface which supports LTE modems could also be turn in LoRaWAN gateway by installation of R11e-LoRa8 or R11e-LoRa9 card.
topaz quarry
man now that's some cool stuff
tame carbon
its neat, cus its low power and has 10-15km range
line of sight
data rates, I'll be honest, not great
and its also not a session based connection
topaz quarry
interesting
tame carbon
but for telemetry, it is awesome
and you can also send data back to the device
but you have discrete messages you pass
topaz quarry
so it's UDP style connections
tame carbon
yeah, so typically, a device has its own schedule for communicating
topaz quarry
ahhh
tame carbon
and duplex is done by the party that receives a connection
so Client sends data to server, server reads its own outgoing message log, and sends any messages in queue back to client
or vice versa, depends on the type of Lora network ,you can do it one of both ways
@topaz quarry but the Things Network is quite cool
its big
v big
tame carbon
There's no protocol stacking with lora
sadly
any services that you connect to it, talk to the lora gateway
which is just an IP service
and a lora gateway, can either be self operated, or by someone else
they talk on the IP layer, to your exchange, which could be on a foreign gateway
so you have clients on the left
the bridge with Lora interfaces which just talks to an internet router
@topaz quarry the reason I think its cool, is cus central europe is absolutely PACKED with gateways
tame carbon
cus we have highly advanced infrastructure
our public infrastructure, sewer systems and traffic monitoring
is all IoT
There's commercial networks too
tame carbon
topaz quarry
like it should just be one big LAN in an airgapped network
tame carbon
These are from a dutch ISP
but that 10 year battery life, can confirm
we had groundwater level meters scattered across large areas
with single lithium ion cell, lasting about 6 years
@topaz quarry well, thats kinda the problem, it needs a backbone
and IP is perfectly reasonable for this
tame carbon
Networks like KPN, have their own intranet for the backbone of Lora
only their message exchange itself, which you use as a customer, is public IP
oh
and it costs money to send data xD
which is why you have to think when you develop this stuff
topaz quarry
gotta love that multi-billion dollar bill from all the telemetry
tame carbon
well
its actually cheaper than setting up SMS modems everywhere
uses almost no power at all
and its readily available in the entire country
they just installed this equipment on the existing 4G towers
but yeah, IoT hype
buzzwords
topaz quarry
idk, at least in the US
all the public infastructure is literally in a full mesh topology
all those fiber backbones
tame carbon
netherlands has like three big fiber loops around the country
and some dark fiber here and there
but its tiny speck of dirt
with 19 million people
topaz quarry
oh the dark fiber in the US is nonsense
like all the power companies have tons
because reasons
topaz quarry
FPL uses it for a smart grid
tame carbon
smart grid is a joke
topaz quarry
but like it's apparently like one of the few
tame carbon
it will never happen.
smart grid on utility supply, things like communicating between power stations, that already exists
but telling your tesla to discharge itself cus neighborhood needs more power, NOT going to happen
Its just going to make grid stability even worse
topaz quarry
well it depends
if you have a distributed power grid
and you have a major power backbone, i've seen it not suck
Florida gets to cheat though
tame carbon
the problem with this concept, is that the local wiring is not up to spec for this
topaz quarry
we have the nuclear power plant off the coast
tame carbon
you get current flows in areas, that are not ment to support loads like that
topaz quarry
above ground wiring?
tame carbon
yeah

but get this, here. we have situations like this:
some farmer, gets subsidies from govt
to build a solar park
total capacity: 30MW
but the cable supplying it
only does 15MW
topaz quarry
interesting
tame carbon
so when a lot of sun shines, those inverters actually shut down, to prevent overloading of network
topaz quarry
you know California has this problem
tame carbon
because utility companies don't make as much money on "buying" electricity, and doing this at a large scale requires investment into the grid
topaz quarry
and they pay Arizona to take the overages
tame carbon
so they aren't interested, and just leave it at lower power
cus burning oil & coal is just... easier
topaz quarry
it's also cheaper in the short term
topaz quarry
short term monies is what they care about :/
tame carbon
yes
their short miserable hooman lives

@topaz quarry one thing that everyone should be doing though, is install solar on their house.

mostly, because, I don't see a reasonable alternative as of right now
but I don't want those PWRs
topaz quarry
there's some micro nuclear plant designs
topaz quarry
because 15 year investment plans

with multiple billion dollar debt ceilings
tame carbon
This is what gave me hope for a green future ^
topaz quarry
are super scary
tame carbon
because pressurized water reactors are just a dumb idea
they are incredibly inefficient, like 0.5% of actual fuel used
topaz quarry
the british keep trying their hand at nuclear fusion
tame carbon
and they can melt down, and can also have hydrogen explosions
fusion, I don't have my hopes for
fission works, and we can deploy it
@topaz quarry look up "Kirk Sorensen"
He has lots and lots of talks
even did one at the technical university in Delft (netherlands)
topaz quarry
neat
tame carbon
He's former nasa aerospace engineer
and he came across liquid fuelled reactors, when he was envisioning a lunar community
tame carbon
xD
topaz quarry
but because we're scum
tame carbon
we've had this alternative form of nuclear power, since 70s
topaz quarry
they'd just shoot with a rocket
tame carbon
but Nixon wanted to make jobs in a specific state, so he cut funding to Oakridge
and killed the MSRE
topaz quarry
ah yes
tame carbon
ran for 5 years
topaz quarry
i remember seeing a tad talk on this
tame carbon
and was only stopped because of politics, not because of technical problems
topaz quarry
politicians do dumb things
tame carbon
I am fascinated by this technology
I have to work right now, otherwise I could go on a 2 hour tangent about this tech
Because
reasons
@topaz quarry these reactors don't require pressure vessel, they operate at much higher temps
and cannot suffer from either chernobyl type or fukushima type disaster
tame carbon
There's no "meltdown" possible, since the core is already molten
and the "emergency" system of the reactor, is a frozen plug of salt at the bottom of the vessel
cooled by a blower that blows cold air over the pipe
if power is lost
that plug melts
and the entire reactor core drains into a specialized tank
which is designed for this exact scenario
with traditional reactors, water has to be kept on the core at all times
that drain tank, has no moderator, it goes subcritical, fission stops
only way to start it back up, is by melting the fuel, and pumping it back up into the core
tame carbon
liquid fuel in a solid moderator (graphite)
instead of a solid fuel in a liquid moderator (water or heavy water)
heavy water is used for low enriched uranium, because it absorbs less neutrons
@topaz quarry the reason it hasnt been used yet
after ORNL closed up shop
nobody knew, for 40 years, that this was even an option
only in early 2000s, when Kirk uploaded scanned PDFs from a book he found on a shelf
did this get featured in Time magazine and Science
and since 2010, dozens of startups have begun developing this
we'll see first commercial LFTRs in next 5 years
topaz quarry
again if our race wasn't a community of fucks
tame carbon
main reason right now, is once again... economic incentives
Molten salt is very corrosive
topaz quarry
we could just use a space elevator
tame carbon
and they currently can build vessels that last 15~ years
but it needs 20-25 years to be viable
tame carbon
but once we can figure out how we can use molten salt..
we will never run out
thorium-232 is simply too common
don't need enrichment plants
waste profile is 1/35th of uranium-plutonium fuels
and produced waste, does not contain transuranics, so its only fission products which are done being radioactive after about 300 years
U-238 is the boogie man in nuclear power
when it absorbs a neutron it becomes plutonium
and plutonium is the biggest polluter
needs storage for over 100k years
Thorium 232 absorbs neutron, becomes Th-233, which has short halflife beta decay, to Pa-233
Pa-233 has a 27 day halflife, before it turns into U-233 through beta decay
because these are different elements, you can do chemical seperation
and this is the key in thorium efficiency
it needs a sort of chemical "liver" to clean the nuclear fuel
you can also mine a thorium reactor for rare resources
quite a lot of fission products, when they become stable, can be sold for profit
materials such as Krypton and Xenon
or other medical isotopes
can be extracted from the reactor while it is operating
@topaz quarry oh well, nuff said

What is the term given to setting up an access point wirelessly?
unborn sluice
wap
toxic citrus
Effective?
clear igloo
You mean where it connects to other APs via wireless only? Mesh is the other term
toxic citrus
I think it's wap, and not the other type of wap 😳
unborn sluice
what's the other wap
toxic citrus
I'll check and see if that's a setting on my modem
peak cloak
WAP means Wireless Access Point
toxic citrus
what's the other wap
@unborn sluice the "song"
peak cloak
idk what you are thinking about 
unborn sluice
I'm not gonna ask any further question. it would be more obvious I know about pop
toxic citrus
Right but is wap a good way of doing things or should i route a cable up to the AP?
Latency doesn't matter
unborn sluice
but throughput does
toxic citrus
What
peak cloak
the wireless in WAP means that it emits wifi
toxic citrus
I want my ap connected to my main modem
clear igloo
correct, APs that talk to each other via wireless are in a mesh. Some use dedicated 5GHz channels to minimize the impact to throughput and whatnot
clear igloo
Probably a combo unit
toxic citrus
Combo
peak cloak
oh yeah
toxic citrus
Stock oem garbage
unborn sluice
toxic citrus
It's 4g though i have no choice
peak cloak
wire up the WAP if you can
unborn sluice
4g?
toxic citrus
Right that means using a powerline adapter then and that's oof
4g?
@unborn sluice yes, Rico, 4g
unborn sluice
oh so it's a wireless modem
toxic citrus
I want to conmect this:
peak cloak
or if your router supports mesh you could try to see how it works
toxic citrus
To this:
First pic is Huawei b525
Second pic is Asus dsl-ac55u
I know the ac55u works as an AP when hooked up directly but that woul mean using powerline adapter 🤮
toxic citrus
All the way upstairs is not ideal
peak cloak
it's possible, just hard because of all the beams and stuff
peak cloak
I still haven't wired up the upstairs either
toxic citrus
So I wanted to set it up wirelessly

you're dad would pay for the speed
not the 2.4 wifi or 5ghz
if he does, something is not right
peak cloak
what does price have to do with wifi gen?
thick rune
he has a hitron hub and says that he has to pay for both

unborn sluice
You should be paying for the speed, e.g. your 50mbps or whatever
peak cloak
yeah

@rocky badge dont block icmpv6 its bad
@topaz quarry i think he turned off his tunnel lol
peak cloak
Would it be bad practice if I block my internet facing servers from being able to ping my LAN. I already have a block new rule from the server subnet to the lan.
hollow marlin
You should have your internet servers segregated to your LAN yes. If you have a decent firewall thats where zones come in
tame carbon
I got a 2nd bridge for that
and firewall rules between those two
another reason why windows is crap: https://i.imgur.com/npdLog6.png
hollow marlin
Basically the same thing in tik world
tame carbon
my /29 is routed through my wan address
so most of the firewall stuff that is there by default, blocks it
so you have to add some accept rules
@hollow marlin oh, this is actually outside of the IP stuff

Hmm, anyone happen to know how I'd configure my unbound internal DNS to ignore one of my upstream CNAME records for my domain? (I've got *.ddns.mydomain mapped to ddns.mydomain, which is fine outside my network, but I think it's causing issues with some of my devices on my network trying to use the ddns synthetic A record rather than the proper internal IPs)
flat lion
@topaz quarry , yeah, but with what? I don't want anything internally to point to ddns.mydomain except that bare URL.
topaz quarry
you just buy a domain and point to it externally use an external DNS system like cloudflare
and point to it internally using your own DNS resolvers
otherwise if you insinst on using someone else's domain name which you do not own then you have to use NAT reflection
your router will figure it out
peak cloak
app.mydomain.com 192.168.1.200
External CLient -> Cloudflare NS
app.mydomain.com 69.123.123.123
he doesn't want to do that
topaz quarry
he wants to use a domain he doesn't use and not use a public IP
in other words he's using a free dynamic dns service that has provided him with a hostname free of charge
now the way you can get your router to figure out what's happening is just tell it that it should use NAT reflection, so when it gets a query to go outbound ti goes oh i see
and instead points internally
topaz quarry
lol right
topaz quarry
oh really?
peak cloak
yeah
topaz quarry
i still have an active student account
and an active edu email
maybe i can squeeze something out of it
oh really lol they provide legit domains through an actual registrar
it's like $7 a year so i didn't actually think about it
topaz quarry
same
Google has io and app
since they decided to become a registrar as well
they also have dev
peak cloak
it's sort of annoying as when I say presentmonkey.tech they think I said presentmonkey.tek
peak cloak
topaz quarry
not far from $7 a year
peak cloak
what are those?
topaz quarry
certs with your exact domain on it with an upsteam CA
topaz quarry
you would only care if your customers care
but if this stuff is just for you
it literally doesn't matter
peak cloak
yeah, for a homelab it doesn't matter
should I transfer my domain from .tech to namecheap?
topaz quarry
up to you?
i personally don't care who owns my domain name
i just use cloudflare for DNS
peak cloak
prob will, .tech costs 30 bucks a year
topaz quarry
it all shows up on the same pane for me
peak cloak
yeah same, cloudflare dns
topaz quarry
then always choose the cheaper option
when you switch give 24-48 hours for updates to occur
it shouldn't take the long but DNS is complicados

hi guys I am new to networking and i got a question
what does 'ndisc_router_discovery() failed to add default route' means
hollow mural
anyone use Synology Drive to sync to NAS, and if so you know why it has to process all the thousands of files I have synced every single time the program opens?
hollow marlin
hi guys I am new to networking and i got a question
what does 'ndisc_router_discovery() failed to add default route' means
@elder linden Not sure what OS that error is from but if the router is handing a global v6 router address then it will fail. It needs to be set to the link-local.
if IPv6 is not being used it can be ignored
flat lion
@topaz quarry , missed your message back. I own the domain (via Google Domains)
peak cloak
then yeah, look at my diagram
doesn't need to be cloudflare you can use google DNS too
flat lion
At this point I'm chalking it up to screwiness with iOS's caching in particular. If I actually query hostname.ddns.mydomain pointing at the pi4 as the NS, the appropriate results are returned. But my iPhone keeps trying to use the public IP which hasn't got any ports forwarded
peak cloak
android is also screwy
at least in the newer verisons of android, I can't get it to use the local DNS server
flat lion
I also have a suspicion it's something to do with the new DoH with iOS 14.
topaz quarry
then just point to your domain internally
ios 14 still respects DNS settings
so if you give it a DNS server, it will use it
elder linden
@hollow marlin thanks. I am trying to fix my modem. I got a 1000mb plan and i am only getting 15 mbps rn
flat lion
Well that's just it, as far as I can tell, it's using the pi4 as a DNS+DHCP server as it should, but it keeps trying to take pi4.ddns.mydomain and go to the public A record
peak cloak
you turned off router DHCP right?
topaz quarry
then that's why it's doing that
peak cloak
just making sure
topaz quarry
yes don't create broadcast storms
flat lion
Yeah, it's off. And the 4 & 6 addresses are right (both the pi), I've checked
topaz quarry
do you have peer dns on?
flat lion
mDNS/Avahi? No
flat lion
The router is also pointed at the Pi
flat lion
Kinda doubt it, it's literally only the iPhone that keeps doing this. Everything else returns appropriate A+AAAA records for hostname.ddns.mydomain inside my network
Router is set to stateless V6, RAs disabled, with the Pi set up as the v6 DNS server + v6 router via tweaking ipv6_forward
topaz quarry
then just block every DoH
address
the iphone will default to the DNS
if what you're saying is true
waxen saddle
It’s something with your setup. I can tell my local dns server to point any domain to any IP I want and my iPhone has no issues routing to the ip I specified for that domain.
flat lion
Well like I said, I don't know what exactly the root of the issue is. It could be caching the public A record cause of the cname for *.ddns to ddns, or it could be some DoH issue since I'd recently updated the phone to iOS 14.
topaz quarry
if you think it's caching the flush your dns
if you have ipv6 on, it's 99% probably you have peer DNS turned on somehow
if you think it's DoH then just block every DoH address (isn't like there's a ton of them)
if you're unsure, use wireshark to see who your iphone is asking for DNS records
flat lion
I know dis and re-connecting to the network (which as I understand it will flush iOS'es cache) will get it to connect to pi4.ddns.mydomain, but it's kinda annoying to have to do repeatedly
topaz quarry
then create a wirguard instance
and tunnel your iphone to your infastructure at all time
lol if flushing your cache solves the problem
it means it's picking up an A or AAAA record from it's LTE connection
and keeping for the duration of the TTL
flat lion
Mobile data is off
topaz quarry
then how would it get another DNS server
flat lion
I've been asking myself the same question for the last several hours
flat lion
Well I am on Linux lol.
flat lion
Arch on my Tower and Arch ARM on the Pi
peak cloak
like on the phone

What v6 servers is the iphone getting? Pre-post testing

Yeah, I just installed it and got it fired up now
hollow marlin

flat lion
Blech, looks like I gotta log back out and back in first
flat lion
@hollow marlin it's got the pi's v6 address for DNS and 172.16.0.2 (again, Pi) for v4
