idk im just thinking about them rn

[timid quartz]

think about code…or smth…

[spare quartz]

well

there is a problem im facing rn

i just dont know how to execute it rn so im watching youtube

(essentially how would i defer the execution of a lambda until the thing that made it is ready to run it)

AHA

[timid quartz]

Erm on your computer with ./your-thing.exe

[timid quartz]

Holy null checks

[spare quartz]

it used to look like this but i didnt want to repeat the same logic

[timid quartz]

Kotlin should have guard statements

func greet(person: [String: String]) {
    guard let name = person["name"] else {
        return
    }


    print("Hello \(name)!")


    guard let location = person["location"] else {
        print("I hope the weather is nice near you.")
        return
    }


    print("I hope the weather is nice in \(location).")
}

[spare quartz]

it does

val name = person["name"] ?: return
val location = person["location"] ?: run { println("alpha"); return }
println("beta $location")

its called an elvis operator

[timid quartz]

?:

It looks confused

Like your whole language

[spare quartz]

rich coming from the person who didnt even know the operator existed

[timid quartz]

uhm yeah cause I’m not a copelin user

[spare quartz]

cause you're lame and think go is good

[timid quartz]

better than Kotlin :3

no JVM

[spare quartz]

Kotlin/Native

[timid quartz]

but who even uses that

we all know Kotlin is primarily a JVM language

[spare quartz]

does it matter

[timid quartz]

one of the big draws is Java compat

[spare quartz]

you said "Kotlin" which just means the language itself

the language is compilable to 4 environments

i could've said WASM or JS in place of it

(and if you count the work of Graal, that too)

[timid quartz]

still…go isn’t kotlin…therefor better

@lone sky your the worst best example

[lone sky]

[timid quartz]

ok so like

once I have a dhcp address

How do I like…use that

[spare quartz]

RAW socket

write the ethernet frame which uses the local interfaces MAC address

then write an IP frame over that with your newly allocated address

[timid quartz]

oh so

manually

makes sense

[spare quartz]

well unless you had another way to tell the OS to make a new interface for your ip

[timid quartz]

would have to be an 802.11ac or x frame

but same deal

[timid quartz]

Actually I may be able to just use a raw socket for IP and not have to write a L2 frame

Something like socket(AF_INET,RAW_SOCKET,...)

Cause it seems like it’s harder to write to a WiFi NIC than it is an Ethernet NIC

[spare quartz]

Good enough

[timid quartz]

huh ok in my quest I have discovered that 802.11 NICs tend to present frames to the OS as Ethernet frames and not as 802.11 frames

unless you're in monitor mode in which case you'll get the 802.11 frame along with management AND data frames

yeah

raw socket on rust needs a library

maybe I could see how the library does it tho

[spare quartz]

depends on OS (even permission wise)

i believe you usually need some form of system access (either thru root or Administrator on windows)

[timid quartz]

well even for the program structs

cause it doesnt have raw sockets directly exposed

[spare quartz]

UDP is the easiest by far in terms of construction

its just size/checksum/data

TCP is (somewhat) simple to write a state machine for

and ICMP is also really easy to write (unless you want proper safety with enums where it becomes tedious, its a directory of opcodes)

[spare quartz]

ps: ensure your IP checksum is correct [unless you know your NIC can offload this]

remote computers (or even middleware) will completely ignore them if its wrong

@spare quartz I figured I might as well run dhcp over my raw stuff too

[spare quartz]

okay, just make sure you can support UDP broadcasting

(your initial DHCP line will be to query who the gateway is)

hmmmmmmm

ok so if I dont fragment

[spare quartz]

back

[timid quartz]

I can just set it to 0

[spare quartz]

my bluetooth connection is dead

[timid quartz]

cool

[spare quartz]

you are advised to fragment as little as possible

this means stay below your MTU though

if you exceed that the peer will hate you

rrgh ok so flags bitfield raaagh

network order

big endian

ugh all of this has to be big cringean

[spare quartz]

big goodian

[timid quartz]

well ok

the flags would just be 010

palindromic

[spare quartz]

what is the size of the flags field again

[timid quartz]

3 bits

[spare quartz]

then you dont need to worry about endian

[timid quartz]

yeah

[spare quartz]

bit order will always be on the right for least significant

[timid quartz]

welllll I'm going to uhm

so

[spare quartz]

if its on the left for network ops you should kys and not deal with it

[timid quartz]

uhm

3 bit flag + 13 bit fragment offset (0)

010 + 0*13

well honestly

i could just

have it all 0

idc if the peer fragments my packets cause it can handle that

[spare quartz]

im pretty sure DF is aimed towards middleware

(like a router in between a line to a remote computer)

HOLY SHIT AAAA MENTIONED

[timid quartz]

Probably just gonna have my thing cry if it gets a fragmented IP packet

Unless I only get fragmented IP packets

[spare quartz]

your router will most likely not fragment anything

at least before you get into IP with a very large message

[timid quartz]

if the upper layer is smart it’ll send its packets with a max size of an ip payload so it doesn’t have to fragment

ok system is little endian

must do conversion manually

[spare quartz]

did you just check if it was

[timid quartz]

yes

[spare quartz]

on any conventional (still extant) system it will always be little endian (x86 / ARM / RISC)

the only big endian systems that come to mind at the moment are PowerPC

(there is also mixed endian but such systems are nonexistant in the grand scheme of things)

[timid quartz]

me when I mix your endians

rrrrgh ok

[spare quartz]

what i would usually say to do is create an endian flipper based on the local architecture but im unsure how much rust says there

ok so

max ip packet is 65515

[spare quartz]

question mark

[timid quartz]

well for data

cause header is 20 bytes

and max 16 bit uint is 65535

[spare quartz]

oh

[timid quartz]

so max ip payload is 65515

[spare quartz]

the header might be smaller than 20 bytes

depends on the line

but yes

[timid quartz]

? no

for v4 it should be 20 bytes

[spare quartz]

IP VJ compression

[timid quartz]

wont happen im not doing that :3

[spare quartz]

well it means im not wrong

and it depends on your line

[timid quartz]

ok yapper

[spare quartz]

stupid

but the actual limit is the MTU

which for most devices is 1,500 bytes

[timid quartz]

ok vj compression is for tcp/ip

not for just ip

[spare quartz]

ys

depends on the line

[timid quartz]

what line!

[spare quartz]

you realize ethernet isnt the only carrier of IP yes.

[timid quartz]

yeeeees

[spare quartz]

it also goes thru PPP and crap

which may say to use the compression.

so it depends on the LINE

actually yeah that makes me have a question

how exactly are you binding

[timid quartz]

good question

Socket has a bind method

[spare quartz]

okay but how does that work

cause most OS binds are tied to a specific protocol over IP

[timid quartz]

yeaaah hence I uhm

maybe that's why it doesnt have ipproto_raw

[spare quartz]

blegh glasses have bad blur gain

need water

[timid quartz]

seems like with C you can just

bind a raw ip socket to an ip

odd

well ok maybe protocol = None will do the trick

what the fuck 😭

[timid quartz]

wait this isnt...

this is wrong

[spare quartz]

issue?

[timid quartz]

type is 1

protocol*

not 17

oh I see

destination unreachable?

cause type 3 code 3

wait but then after that

there suh

oh there's an icmp destination port unreachable

and then the udp packet after

[spare quartz]

61238 >> 2299, # 13 [no data]

[timid quartz]

yeah

[spare quartz]

you might have a partial read

[timid quartz]

mmmaybe idk

idk why there's an icmp unreachable message though

should be reachable

mmmmmmmmm mwait

unless it's because my socket

isn't marked as udp

aha

mmm putting UDP as the protocol results in no read though

wait

yeah no read

weird

[spare quartz]

i hate logic like this

[timid quartz]

idk somehow it must not be binding right

huh ok @spare quartz

if I do Type::RAW with Protocol::UDP I get nothing

but if I do Type::RAW with no protocol I see the ICMP and weird UDP packet

but if I do Type::DGRAM with Protocol::UDP I get just the UDP data (as I'd expect)

[spare quartz]

im confused

[timid quartz]

me too

[spare quartz]

what are Type and Protocol

[timid quartz]

so in the libc function socket

it's a 1:1

domain is IP (could be something like a local "unix" socket though); type is socket (TCP-like), datagram (UDP-like), or raw; protocol is UDP, TCP, ICMP, etc

[spare quartz]

raw and protocol seem antithetical

[timid quartz]

protocol could also be IPPROTO_RAW

[spare quartz]

well what does that do

[timid quartz]

it does what's in the name

u get raw IP

[spare quartz]

okay so why aren't you using that

[spare quartz]

also libc/posix devs were really snorting lithium here

domain as an int is stupidly stupid

even for C

[timid quartz]

I have been (the equivalent here is specifying None for protocol since it's an Option) but then if I try to send the UDP packet I get the ICMP dest. port unreachable and the weird udp packet

[spare quartz]

well why not just

ignore the icmp packet

just keep reading past it

[timid quartz]

I could read_exact byte by byte

but I don't think it's a short read

[spare quartz]

does your read function signal the amount of actually read bytes?

[timid quartz]

I believe so yes

[spare quartz]

print that in tandem with the data (or slice, preferably)

if it ends after udp length its partial read

it'd be really strange if the read was not partial, i wouldn't have any idea on what would cause that

[timid quartz]

56 bytes

highlighted all 56

althought

[spare quartz]

that's super weird

[timid quartz]

huh

for the icmp packet

why does the ip header say total length 36

it's only like 28

[spare quartz]

did not work

PPP is the analog to your Ethernet

which should be parallel to your RAW

[timid quartz]

whereas I'm trying to do some weird shit like that

[spare quartz]

and neither are you!

you're interfacing with a POSIX RAW!!!

thats not a nic

[timid quartz]

I think it's different

if it was as simple as just making a raw udp socket I feel like I would have gotten that by now

[spare quartz]

well

maybe ill try and make a raw socket in kotlin

i just need to find whatever windows does for it instead

[timid quartz]

I am on macos that could be causing something idk

[spare quartz]

Winsock service providers for the IP protocol may support a socket type of SOCK_RAW. The Windows Sockets 2 provider for TCP/IP included on Windows supports this SOCK_RAW socket type.

There are two basic types of such raw sockets:

The first type uses a known protocol type written in the IP header that is recognized by a Winsock service provider. An example of the first type of socket is a socket for the ICMP protocol (IP protocol type = 1) or the ICMPv6 protocol (IP procotol type = 58).
The second type allows any protocol type to be specified. An example of the second type would be an experimental protocol that is not directly supported by the Winsock service provider such as the Stream Control Transmission Protocol (SCTP).

[timid quartz]

but my thought is like

what you did was

essentially

sstp.send_data(ppp.encapsulate(ip.encapsulate(...)))

[spare quartz]

basically

[timid quartz]

and sstp under the hood is interacting with your os's network stack

whereas I'm trying to interact with the OS network stack directly

[spare quartz]

well no

SSTP is just another encapsulate like PPP over TLS which is over TCP

what im saying is

your socket RAW should be analogous to the PPP part of that encapsulate chain

so i do not know why it isn't

what the

okay win32..

[timid quartz]

I think it's more analogous to the IP encapsulated by PPP

because I'm not interacting with L2 with the raw socket

[spare quartz]

sorry i mean after encapsulation

but yes

okay

win32 just got a LOT more interesting for me

i might gotta write a whole BSL Socket

@timid quartz thisi s why i hate you

i was supposed to give YOU something to code

not myself indirectly

[timid quartz]

[spare quartz]

Ws2_32.dll

[timid quartz]

mm

I am reading that macOS is restrictive and could be blocking stuff

[spare quartz]

the worst part about making apis

having to make it extensible for* the future

[timid quartz]

I may have to try this on Linux

what im reading is stuff about BPF (Berkley Packet Filter) and system integrity protection potentially still bocking stuff

[spare quartz]

something windows might actually be good in!

win32 exposes this

[timid quartz]

I did see that yeah but

I did not wanna have to write something to put together a UDP packet yet but I might do that

[spare quartz]

hmm

SocketImpl..

or well, i need to figure out how to load the right socket for the os

[timid quartz]

checksums...annoying...

just let me send my data in peace

I dont wanna have to deal with integer overflow

[spare quartz]

good enough

[timid quartz]

https://docs.rs/internet-checksum/0.2.1/internet_checksum/struct.Checksum.html#method.add_bytes

ok cool I can take the easy way out for rn

[spare quartz]

time to see my error code

its smart!

[timid quartz]

hmmm

send failed: Os { code: 39, kind: Uncategorized, message: "Destination address required" }

but the destination address is ther

that's the ip packet im sending

@spare quartz did I fuck it up?

[spare quartz]

sorry watching something right now

it'd be a lot more helpful if you wrote a formatter for an ip struct

[timid quartz]

ok

[spare quartz]

but yes i see the two addresses.

• packet might be misaligned
• partial write
• something else? (i dont know how you're aquiring that error message)

[timid quartz]

ohhh could be partial write

m nope

still same thing but I flipped a thing

[spare quartz]

how are you getting the error code

[timid quartz]

wdym how

[spare quartz]

you are working at RAW

there should not be such error reporting there

[timid quartz]

sock.send(&ip_bytes).expect("send failed");

this is the line

[spare quartz]

"Destination address required" ?

[timid quartz]

I wonder if it's still trying to handle the ip header

[timid quartz]

that would be the most probable explanation

[spare quartz]

uuuhhh need to open an arena and allocate the struct

[timid quartz]

HEY

IT WORKED

[spare quartz]

good!

[timid quartz]

I just had to uh?

idk why that's necessary

maybe L2 needs it in some way

I wonder what happens if I

although uh

netcat doesnt receive them...maybe bsd restrictions striking again

[spare quartz]

not that im aware of

[timid quartz]

I should try doing this on linux and see what happens

linux might be less...restrictive

[spare quartz]

run it in macos single user mode 👍

[timid quartz]

oh huh

malformed somehow

[spare quartz]

misalignment

read the packet data

[timid quartz]

gonna misalign you

[spare quartz]

thats assault

[timid quartz]

also weird

macos is definitely tampering with my stuff

I set the identification field to 0

but it's not 0 in that packet

yeah

macos is messing with my stuff confirmed

area inside brackets is the actual packet I'M trying to send and I know that because the length is 0x22 = 34

although my length might be swapped around it's not

stupid macos just lemme write stuff

[spare quartz]

turn off sip bro

just turn off sip

[timid quartz]

💀

Yknow it…

Lemme check

[spare quartz]

(im not actually certain if turning off sip will do anything)

(i usually just do it cause its more restrictive than windows)

id rather live in ohio

(unfortunately ohio has an even worse bug problem than here in the summer)

(and the temperatures are also not great, but it beats the possible 120 heat index)

lol southeast US has bad bugs in the summer too

[spare quartz]

(winters are also brutal but i prefer that)

[timid quartz]

sand gnats raaaah

@rustic vine pls relate

do not roll in the grass in ohio

you will experience 1 billion of those spiky grass things and 1 trillion gnats eating you

also spike balls ❤️

oh ic

so you're basically saying an enum can be mapped to another type

[spare quartz]

yes

as long as its comparison operator isn't crap

i haven't found a use outside strings/numerics for mappings but its possible

[timid quartz]

also u could just tag it
