haiii

[hazy root]

they have their own web server, but I won't be surprised if the original people working on it long left and there are some misconfigs

and to be fair, exports as large as the ones that give me errors are rare, I have 4 problematic cases in more than a million exports

[edgy pelican]

of course they do

lmao

The last question is asking "Why weren't there any NDP events?" The answer is supposed to be "PCA1 already knows the MAC address of PCA2 so it doesn’t need to use Neighbor Discovery." But in my case, there is an NDP event at RTA. What's happening here?

[gentle trench]

How does UPNP work, and what are its uses?

Some articles say it allows devices to communicate in your LOCAL network, and some say it automates the port forwarding process, for which you had to set up port forwarding on your router admin panel.

Well, aren't devices already discoverable in local network? And even if they aren't why does it open ports for LOCAL network communication?

[edgy pelican]

why are you capitalizing LOCAL

[crystal current]

It allows port forwarding to be set up automatically. The alternative is to do it manually. You're right that devices on the same LAN can normally communicate already, but your PC can't automatically set up port forwarding on your router just because there is network connectivity

[gentle trench]

Why do articles say that it allows devices on local network to communicate \😕?

[gentle trench]

to emphasize on it.

[cedar forum]

my guess would be the wording is meant to be allows two devices on local networks communicate without becoming devices that are publicly accessible

it is two devices on local networks establishing a p2p connection

also -- it would help to maybe cite one of these articles, that wording could mean anything

i think you are probably confused here because uPnP does both of these things

the local part of uPnP is essentially just SSDP, iirc it builds on top of SSDP to discover local devices

but then local devices are able to negotiate port opens as well

so when you wire up a new device it will both publish "i am a device at address X.X.X.X and provide Y features", like printers or TVs or w/e

but it can also say "i require port 8080 opened on the router" and uPnP enabled routers can understand that request

it's confusing because it's such an expansive but also kind of little-known protocol (at least for the specifics)

[gentle trench]

ye, I got most of your points

[karmic glen]

Hello guys !

I am hosting a game (Palworld) server on my PC. I coded a discord bot that sends the IP adress of the PC on a discord channel (couple of Irl friends and family dw about security issues).

The bot will send the IP whenever it changes (due to connexion resets or anything), or when querried with a command. The bot works well the code is pretty straightforward.

I have a domain name and I wish I just point it to the IP adress that would work even better than copy pasting the ip every time from the bot.

The issue is: the ip changes 2-3 times a day.

I'm lazy to just go do host dns setting and point it again with the new adress so, is there a way I can do that automatically?

Hey everyone I think this is the correct channel for this. Im using a program called scapy for IPv6 packet minpulation. When ever i send a packet it gets no replys. But if i turn on wireshark it gets a reply. I thought this was the strangest thing ever. Is it that wire shark is actively lessoning to the connection and that is why there is a reply?

Hey guys, has anyone used fabric to create chain of jumphosts for networking devices? Im trying to have a core switch be a jump host, by jumping from it into an access switch. Im currenlty using the "Connection" class for connecting to the access switch, but I don't know how to do this for local network connections where the connection string is ssh host instead of ssh user@host.

conn = Connection(
    '1.2.3.4',
    connect_kwargs={'password': 'password'},
    gateway=jump3
)

[modest echo]

im trying to check if forwarded a port in the correct way but it shows this, does that mean the port 25565 didnt get forward?

[modest echo]

what's the difference between LISTENING, TIME_WAITING, ESTABLISHED ?
and after i made "port forwarding" it says the ip:25565 then TIME_WAIT

[cedar forum]

LISTENING is a port on your PC that is ready to accept connections on the specific port
TIME_WAIT is the soket is a socket that is closed and the PC is waiting for confirmation from the other side on closure
ESTABLISHED is a socket connection that is active and two devices are communicating

   ESTABLISHED
          The socket has an established connection.
   SYN_SENT
          The socket is actively attempting to establish a connection.
   SYN_RECV
          A connection request has been received from the network.
   FIN_WAIT1
          The socket is closed, and the connection is shutting down.
   FIN_WAIT2
          Connection is closed, and the socket is waiting for  a  shutdown
          from the remote end.
   TIME_WAIT
          The socket is waiting after close to handle packets still in the
          network.
   CLOSE  The socket is not being used.
   CLOSE_WAIT
          The remote end has shut down, waiting for the socket to close.
   LAST_ACK
          The remote end has shut down, and the socket is closed.  Waiting
          for acknowledgement.
   LISTEN The  socket is listening for incoming connections.  Such sockets
          are  not  included  in  the  output  unless  you   specify   the
          --listening (-l) or --all (-a) option.
   CLOSING
          Both  sockets are shut down but we still don't have all our data
          sent.
   UNKNOWN
          The state of the socket is unknown.

[modest echo]

uh makes sense
im trying to port forward so i can play on a server with my friend
and when i do (netstat -na | findstr "port" )
it shows time_wait so i guess i didnt port forward in the correct way even tho i followed a guide
where do you think i should start to fix this?

[cedar forum]

i'm not quite sure what you mean here, do you mean you've port forwarded something on your router? if so, you won't see any changes on your local PC. i would not be surprised though if you need a firewall amendment for this

[modest echo]

trying to port forward 25565
for a Minecraft server on my PC
I followed a guide and added a new rule in my firewall with that port and did both UCT/UDP

so idk where the issue is :(

[cedar forum]

and you've added the port to your router?

[modest echo]

I tried yeah
idk if I added it in the correct way tho but after I added it the server loaded for me when I added my public ip to Minecraft I see the server
but when my friend does it he can't see it

[cedar forum]

so you put your own public IP in? that probably doesn't test anything because you are on that network

it sounds like a firewall thing or a problem with the port forward, though it's a really niche one and quite hard to debug over discord

[modest echo]

hmmmm yea probably either firewall or port forward since server is working fine for me but doesn't show for my friend
do you know where should I start from to debug it?

I have an idea, is there a way to check if the 25565 port got opened correctly?

[cedar forum]

see if your friend can ping the IP maybe, though that's not always reliable. you should see entries in your netstat when they attempt to connect to you, including if it gets blocked by the firewall, something like wireshark might help to debug actual packet stuff

but port forwarding is a pain and there is no great way to tell you which bit of the process to start by diagnosing

[modest echo]

when my friend pings it it says request timed out

[cedar forum]

hmm okay -- doesn't necessarily mean loads as routers can block pings, often consumer ones do

there's not a whole lot to advise here, you can try something like https://www.yougetsignal.com/tools/open-ports/ maybe?

[modest echo]

so when i put my ipv4 in minecraft it's always on (makes sense cuz it's local)
when i put my public ip it doesnt work and show for me unless i port forward in the way i do in my router

[cedar forum]

only if it's a TCP port though, i am unsure what minecraft uses

[modest echo]

yea it says closed

[modest echo]

i did both TCP and UDP

[cedar forum]

yes but does minecraft use TCP or UDP

you can only port check TCP due to the nature of how UDP connections are "fire and forget"

okay it's TCP

so yeah if it's closed then your router is not port forwarding correctly

or you have not set the forward correctly to push it to your computer

[modest echo]

im not sure what to not show on a public discord server but i think this is fine

[cedar forum]

yeah i'm unsure really -- if that is your desktop IP and it's not registering then next step is to check the PC

you added a windows firewall rule right?

[modest echo]

yea i did
2 inbound rules one for UDP and one for TCP
2 outbound rules one for UDP and one for TCP

[cedar forum]

hmmm

[modest echo]

maybe i did sumn wrong here? i dont think so tho hmmmmm

[cedar forum]

i am completely clueless then, i am only familiar with linux networking really so can't really help you isolate where this is going wrong

that port forward looks correct

it also depends entirely on whether your ISP allows port forwarding at all, the presence of it on the router does not necessarily mean anything here

a lot of ISPs will not

or will make you pay extra

[modest echo]

yea that's what im thinking off
the ISP might be blocking it :/

[cedar forum]

you could speak to your ISP

[modest echo]

they are dumb for the most part here ngl
customer service sucks rlly bad

[cedar forum]

yikes

then your best bet is probably getting a cheap VPS somewhere to run a minecraft server on or looking at a VPN that allows for port forwarding through the VPN IP, or something like Cloudflare Tunnels

[modest echo]

if you have a problem they just tell you to "restart the router" 💀

[modest echo]

cloudflare tunnels hmm sounds good
will check that, thanks appreciate you

[modest echo]

when i removed the way i port forwarded in my router the server now says "cant connect to the server" when im using my public ip
so i guess that port forwarding was doing sumn

[cedar forum]

that sounds like a problem from the router to your PC then

[edgy pelican]

are you sure they dont have a CGNAT

[modest echo]

whenever they try to join the server now it says
connection timed out: getsockopt

[modest echo]

i turned off the firewall in the router page and we can ping it now but cant join the server hmmm weird

[safe lantern]

hey I'm not sure which channel to ask this in, but is anyone familiar with connecting to a mysql server on an AWS RDS instance?

[crystal current]

Sounds like a DNS / firewall / network issue. Where are you trying to connect from? Is there a network route and security group allowing access?

Pretty cool

[rain bear]

Hey, I've a question about networking but it's not related with python
recently I studied network topologies and I found one of them called "Star topology" and it seemed pretty similar to the idea of the switch so is it the same thing or there is a difference between them ?

[cedar forum]

star topology is a topological idea, switched network is an actual physical hardware device

a switch is a physical implementation of a star network

the difference is that the concept of a star network also encompasses hubs

[rain bear]

so all the topologies are logical ideas to connect devices ?

[cedar forum]

yeah, and you combine a selection of hardware devices to achieve those topologies

are you familiar with switch vs. hub?

[rain bear]

yeah switch sends data to a specific PC while hub streams it to all the devices

[cedar forum]

yep exactly, so if you look at the start topology, you can see that both of those technically fit that description, whilst also acting slightly differently

in terms of the physical cabling layer, they are the same, but they differ at the routing layer

[rain bear]

I thought about it and find that the bus & ring topology can be like hub-based while star can be done with switch
that's why I asked (I mean the idea not the shape of the circuit)

thank you so much btw

[cedar forum]

yeah that's another good way of thinking about it. ring networks and bus networks only work if:

a) the devices in the network are configured to forward on packets not destined for them and
b) the devices receive packets not destined for them in the first place

which as you've identified, hubs will do

that's around the time where you start mixing together topologies and having, say, a bus network running off a star network, one central hub and then chains of devices running the bus network, etc. etc.

[cedar forum]

no problem!

I am writing a connection class for server and client. I have got into a problem while closing the socket.

[woeful ridge]

Hi

I Want To be a network Engineer

So Can I get some support

[ionic blade]

The call to sock.close() is made after the sock.shutdown(socket.SHUT_RDWR)

and see as per docs

Note close() releases the resource associated with a connection but does not necessarily close the connection immediately. If you want to close the connection in a timely fashion, call shutdown() before close().

[ionic blade]

can anyone test the server connections for me?

[hallow python]

yo all my ports are closed why is that

[cedar forum]

need more details than that

[hallow python]

i just did a port scan on my ip and they are all closed

[cedar forum]

do you have any port forwarding set up

[hallow python]

nope

[cedar forum]

there we go then

[hallow python]

i dont even know what that means sir

[cedar forum]

are you talking about your home IP?

[hallow python]

yea

ik that its good that they are all closed but idk why thry are tho

[cedar forum]

so every device on your network shares the IP of your router, that's called NAT (network address translation)

that means that when someone tries to connect to a port on your public IP (your router), the router by default doesn't know which device on your home network to send it to

you have to configure a rule in your router (port forwarding) to say "when someone connects on port 8000 to the router, forward it to <LAN IP>"

[hallow python]

oh

but thats weird even http and https are closed

how am i connected to the internet then

[crystal current]

A port scan is meant to check for ports open to accept incoming traffic that is not initiated locally. You need the port open if you have a web server, but not just to browse the web

[hallow python]

oh thanks for explaining

[cedar forum]

yeah so when you connect to say, google.com, you connect on port 443 for HTTPS

your computer picks an outbound port in the ephemeral port range

on Linux that's ports 32768 through 60999

so then the actual communication is between 192.168.0.1:42531 (or whatever ephemeral port is picked) and google.com:443

when google replies, it sends it back to your computer on that temporary port, and that port is directed back through your router firewall

NAT complicates things slightly because your PC has an outbound port and the router also has an outbound port and translates between them, but that's the basics of it

[hallow python]

thats a really good thing to explain it ty for ur time

did u make that

[cedar forum]

hahaha no stole it from google

[hallow python]

ty for explaining

am new to cyber so i only got like 50% of what u said but ty still

[cedar forum]

the basics is, to send data to google, you need to know the google port, and to receive data from google, google needs to know your temporary port

think about it like sending letters in the post, the recipient can only send you a letter back if you include your address

[hallow python]

yea

[cedar forum]

that's all the source ports are, they are temporary receiving addresses that let the server send you information in reply to your packets

and they are ephemeral (essentially meaning "temporary") because they are picked randomly and recycled after a connection has finished

[hallow python]

source ports are from 1 to 1000?

[cedar forum]

varies by operating system, source ports on windows are around 49000 to 65535

linux is 32768 through 60999 as mentioned

[ember ledge]

my server will not run at http://3.80.52.123:8000/
am I writing the IP wrong?

[cedar forum]

i'd ask you don't put IPs in channels as it leaves users prone to exposing their IP

when you say not working, do you just mean that nthing can connect? how are you running this? what platform?

[ember ledge]

I can not connect by entering the link above into a web browser

[cedar forum]

and for the latter two questions?

that's an AWS IP, are you just using an EC2 instance?

[edgy pelican]

how does your router know what temporary port you're using and forwarding the data back

[hasty quest]

The router chooses what port the remote should reply on

That's what the source port field in a packet is for

it goes in the destination port field of the reply

i.e. router knows 53129 is available because it hasn't been reserved for any other purpose yet

it puts src: 53129, dst: 443 in the TCP connect and reserves that port for this connection

webserver sees this and replies with dst: 53129, src: 443

router remembers that it picked 53129 for this specific connection and knows where to route it.

[edgy pelican]

interesting

[hasty quest]

It can even multiplex ports if they have different remote ports and/or remote IPs

as long as there is some specific combination of connection-identifying info that's unique to one connection, it's possible to determine how to route it.

Though that makes the routing code more complicated - some routers work this way, others don't.

[ember ledge]

Can someone explain the difference between an empty string and a local host?

[autumn roost]

hi got a question regarding to a synology nas

so it won t get on the cloud

all my sync rules are oipen so not sure what to do

Also no new change logs

[autumn roost]

Did it again the .init file ruins all (100gb file for game engine)

[autumn roost]

🤡

[trail bridge]

why do you think you need to sync the desktop.ini file?

[autumn roost]

i don t but it im trying to exclude it but it doesn t want to do that either

[trail bridge]

oh.. exclude.. i read it wrong from the start

it looks like you are excluding it, the file is unsynced. isnt that what you want?

[autumn roost]

yeah kinda but now the rest doesn t seem to be have the cloud icon so isn t synced properly?

[trail bridge]

you can try to check for the actual files instead of the icon representing the task instead.

[autumn roost]

yeah on my other devices it is synced guess it is a smal ui problem on their side ig and it is triggering my autistic brain leave it for what it is for now ig

(can test it cuz my laptop hardware is too weak) for ue5

so it should be fine? (it only won t do the desktop.ini file of the 100+gb

still seems to store it on my pc wich is weird because of that

[autumn roost]

still stuck btw

[ember ledge]

i cant start server with my own ip adress

with the public ip any help?

[lyric oak]

That's not a surprise, as a (web) server can only bind to the IP address of a network adapter on that machine. If your public IP belongs to another device, you need to forward the packets by network configuration. I wrote a basic guide https://docs.lextudio.com/blog/self-hosting-series-why-cannot-my-web-server-iis-be-reached-from-anywhere-else-8da0e0b252ef for Windows/IIS users, but in general applicable to other web servers/OSes.

[ionic blade]

Can my locally hosted server can listen connections from outside the local network? How can i do it in python?

[crystal current]

Yes... Thee details depend on your network. If you have your own public IP, port forwarding from your personal router can be enough. There are also solutions like Ngrok and Cloudflare Tunnel

[ionic blade]

I probably not hinking of using any external alternatives

[crystal current]

External alternatives?

[ionic blade]

I want to do it in python only. I might prefer the python packages.

i have made a chat app whose server is hosted by the client iteslf locally so i was looking for way to listen incming connections from outside the network

[crystal current]

This is a problem for whoever manages their network. You're not going to change their routing and firewall settings with Python

[ionic blade]

SO whats the solution then?

[crystal current]

To talk to whoever manages their network and ask them to make their server accessible

[ionic blade]

Thats just out of my scope.I thoguth it would be not that much difficult

[crystal current]

The alternative is don't use a server on their network. Ask them to pay for a small VPS or something on the cloud

[ionic blade]

It seems like you are thinking at another level. Isn't there any python package for that?

Im just a student who made a chat app project

[crystal current]

I've never heard of this until I just did a quick Google search right now, might work: https://pypi.org/project/jprq/

[ionic blade]

I looked on the github repo is archived

The code looks small I am thinking to modify that for my app!

[crystal current]

It looks like there are loads and loads of options you could look at: https://github.com/anderspitman/awesome-tunneling

[ionic blade]

You said that you In order to listen for outer (outside local network) connections i need to have settings configured on the network then how doe theses able to work with tunneling?

[crystal current]

In theory, a tunnel lets you get around making any network changes

[ionic blade]

Well thanks, I go an understand tunneling 👍

[ripe hollow]

Hi everybody, I hope this is the correct channel for my question. I'm searching for TCP connection configuration for a server but I have to keep eme (electromagnetic emission) low but I don't have any information about that. So due to my research about the situation; using ping pong, heartbeat or tcp keepalive options increase eme but if I don't use them I cannot know the connection status right? any idea about that? I'm thinking about enabling the tcp keepalive option, then keep the values high and randomizing the transmission intervals in order to avoid predictable patterns.

[crystal current]

I've never had to deal with this personally but I'd be focusing on Layer 1 here, so you can hopefully send whatever traffic you need. https://www.emfanalysis.com/low-emf-internet-connection/

[ripe hollow]

@crystal current Thanks for the information. We will also control the hardware setup. Besides I learned that emitting a significant amount of radio power or sending an excessive number of messages to a server can increase the likelihood of detection. So, I would like to keep the sending messages as minimal. I found about passive monitoring. I think passive monitoring to check server status will work for me, right?

https://www.baeldung.com/linux/tcp-passively-monitor-packet-loss

[cedar forum]

yeah there's various things you can do here to try tune things, I would look into:

• tcp nodelay (disable nagle's algo and send packets immediately)
• tune your window size (see TCP_WINDOW_CLAMP if on linux)
• use a proto that allows for connection multiplexing
• as you've mentioned, adjust your keepalive
• compress where possible

i will say your description of this problem does make you sound like a three letter intelligence agency, but i'm here for it

[ripe hollow]

Thanks for valuable information! Disabling nagle's algo can be very useful for me but please correct me if I'm mistaken, if we disable Nagle's algo the system will send small packets immediately rather than waiting to combine them into larger packets. So, this can lead to more packets being sent over the network, which can increase network traffic that means more em right?

[cedar forum]

you are correct, I was recommending that based off:

in order to avoid predictable patterns.
it sounds like you're going to be doing quite a bit of compromise so it's just one option that gives you a little bit less predictable payloads at the expense of more frequent sending

[strong idol]

It generated 4 threads for 3 users you were right it'd mess up system with large no of users 😅

hello , i have a irc but dont know how to make it online can someone help?

[ember ledge]

I don't have time to help you, but if you're talking about moving it from local to online you need to host on 0.0.0.0 and an open port of your connection (on a windows vps go to the windows firewall and add a rule you have tutorials on the internet)

Hey guys, trying to setup a static IP on my ubuntu server. But its causing me to lose access to the internet. What could be happenning?

[fleet acorn]

[crystal current]

Are you subnetting it to the right subnet? Does another device already have that IP? Could you use a DHCP reservation instead?

[crystal current]

Check Disboard dot org

[digital folio]

not sure if this is the best place to ask this but I am having trouble reading serial
I am attempting to automate login to a particular computer component so that I can set a temporary ip

If I login through command line, I do screen /dev/ttyUSB0 115200
and then I am met with
Login:
When I try to read and print this, I just get a blank space

If I run a command such as 'help' once im already logged in, I can read just fine

[worn drift]

Thank you. This was really useful. My gateway was outside the subnet that I was using for the rest of the subnet. Now its okay. Thank you

[fossil panther]

thx 😮

[edgy pelican]

people still use telnet in 2024?

[cedar forum]

it's very common with embedded hardware

i.e. all the Cisco stuff I've ever used has had a telnet interface over the management port

[edgy pelican]

that doesnt sound fun

[cedar forum]

it's no different to commanding a device over SSH

I am very grateful that the telnet interface exists because it means you can built out-of-band for older switches that doesn't rely on serialport 😛

[grand kayak]

for most use cases I prefer netcat over telnet tbh

[grand kayak]

the major difference is cryptography

[cedar forum]

correct -- but there are situations such as management VLANs where cryptography doesn't matter

[cedar forum]

they are similar but do different things in some situations

[grand kayak]

oh really, what does telnet have that nc doesnt?

[cedar forum]

iirc there are certain features in the telnet protocol that netcat won't interpret because it's solely looking at raw bytes

trying to find a good example / source but am on mobile rn

https://users.cs.cf.ac.uk/Dave.Marshall/Internet/node141.html

this shows a little bit -- basically there are some bytes that the telnet command will interpret and use that netcat won't

[grand kayak]

oh I see. some form of control flow

that can be useful with embedded devices, I think, yeah

[cedar forum]

yeah there are certain control codes used for Cisco switches to do things like disable the password being shown when you type it in

still insecure and transmitted in plaintext, but at least secure against screen peekers 😛

You could use a free VPN like Proton, host your own with OpenVPN or Wireguard, or pay for one... it depends on exactly what you're trying to do, which you haven't explained.

[ember ledge]

I wanna try to get the conection mode from the app, somehow it managaes to bypass somestuff that i want to bypass

Like in my country , they have social packages that only work on facebook and any social media but nothing else , i wanna bypass that so i use that app

[crystal current]

Try Proton VPN then

[dreamy magnet]

If the vpn still doesn't work another option is remote desktop in another country, you can get one in the cloud on aws or azure or something. Probably more expensive than a vpn though

Your ISP controls the public IP of your router. Restarting the gateway may not even change it. But if you want to send traffic through another public IP, you can use a VPN, Proxy, Tor, etc. (If you're talking about the private IP of some device, that's a different matter.)

Correct channel to ask a question about webscraping?

I need to get capacitors from a distributor's website so I can plug them into an auto-solving tool. Or, at least that's the plan. Currently stuck bashing my head why a request works on postman but not on python with beautifulsoup.

^postman request. Nothing too crazy, just probing the home page for now.

HEADERS = { #use human headers to dodge anti-scraping tools
    "Postman-Token" : "13c9fd9e-34a5-4f05-a1ee-a33aeecf526e",
    "Host" : "www.tdk.com",
    "Cookie": "_abck=E..." 
}

def getCapacitorPage(page=1):
    try:
        print("try")
        url = "https://www.tdk.com/en/index.html"
        test_url = "https://quotes.toscrape.com/"
        cookies = dict(cookies_are='working')
        #page = requests.post(url, headers=HEADERS)
        page = requests.get(url, headers=HEADERS, cookies=cookies, timeout=1)
        print("got page")
        soup = BeautifulSoup(page.text, "html.parser")
        print(soup.text)
    except(TimeoutError):
        print("timeout error")
    return page

page = getCapacitorPage(2)```

^python code that gets stuck at the page = requests.get(url, headers=H...line.

It times out without any response from TDK.

I looked online into webscraping pitfalls but I could find nothing. Then, I stripped the postman request bare of all optional headers until it stopped working. I know Hostis a key header, but I still for the life of me can't get python to work.

All help is appreciated.

[tropic moon]

Found it I had mistakes in the headers. I needed both "" and '' for certain fields.

Also, I needed more fields to pretend being a hummie.

(I shamefully admit that gpt came in clutch with spotting the syntax mistakes.)

can anyone tell me why internal architecture of requests is in such a way that requests.json() is a function and response.text is a class or obj?

[barren ocean]

Can someone tell the reason why I lose packets at the destination when I send a ping from a device to an external network?

[prisma cobalt]

I assume it's meant to indicate that response.text which is a str is readiliy available however to get the json representation, it requires parsing on the text, an expensive operation so making it a function is imparting a little information on the user behind the process

also, as every response has a text field but not every response contains JSON, then trying to parse JSON on every response is a terrible idea and should only be done when the programmer requests

[keen cloud]

Hi I have 20 Raspberry Pi devices, and each has an application installed. Some devices are running version 1.2, while others are on version 1.6. Since database migrations are included with each version, updates must be applied sequentially without skipping versions. For example, devices on version 1.2 should update to 1.3 -> 1.4 -> 1.5 -> … -> 2.0, while those on 1.6 should update to 1.7 -> 1.8 -> … -> 2.0.

How can I manage this, or is there a separate application for it? I am considering a node-based approach where each device is updated sequentially, similar to how Windows Updates work, ensuring that no version jumps occur and that all intermediate updates are applied in sequence. How can I achieve this?

[crystal current]

Some relevant discussions about the database issue specifically:

• https://stackoverflow.com/questions/257045/managing-the-migration-of-breaking-database-changes-to-a-database-shared-by-old

• https://laracasts.com/discuss/channels/general-discussion/migration-strategy-for-shared-database-between-multiple-apps

If you really need to do the stepwise upgrades I would ask... how do you do your upgrades today?

[keen cloud]

Hi, I have never performed incremental upgrades before. For example, initially, I had five Raspberry Pi 2GB devices on version 1.2. I used these devices first. Later, I acquired 15 more devices. Before buying these new ones, I distributed version 1.3 to some of the old devices, and I installed version 1.6 on the new ones.
However, now I need to perform incremental updates with migrations. On my test device, I upgraded to version 2.0 step by step. I want to apply incremental updates to the other devices as well, to avoid issues with migrations.

[crystal current]

So you SSH into each Pi and manually run an installation script one version at a time? And you're installing directly on the Pi rather then in a container? In any case you might want to use something like Ansible, or if that's overkill then just write a simple Python script with Paramiko.

You should diagnose why "the wifi is terrible". A free mobile wifi analyzer app would be an easy place to start and understand if the signal is weak, if there is interference on the channel from your neighbors' wifi, etc.

Hello, is it feasable to host PRAW bots through a VPN?

I've noticed that on the free ones the bots just die if I have too many running at once

One bot alone will run for weeks on its own

Two for several days

Three for hours

Etc

Is it just the VPN's bandwidth/quality and the python bot not being able to handle the disconect?

[inland rampart]

I'm not sure, but generally speaking, you should probably just write your code in such a way that it can be restarted without loss of information if it fails, and then you can just automatically restart the bots when they fail and not worry about it.

Websockets would be one way,.or webhooks if it's just in one direction

[jade garden]

Are websockets different from sockets? I've heard on this server that HTTP is abstraction over sockets and websockets is abstraction over HTTP
But then I tried googling this stuff and got really confused (maybe my google skills just need work), I couldn't find any resource describing the difference between websockets and sockets and when you would use each

[vale raptor]

https://datatracker.ietf.org/doc/html/rfc6455.html
from my understanding, websockets is a protocol just like HTTP, and both of them normally rely on communicating over TCP sockets, making them "TCP-based" protocols (besides HTTP/3 which uses QUIC, a protocol based on UDP sockets)

see also their introduction sections, 1.1, 1.5, and 1.7:

The WebSocket Protocol is designed to supersede existing bidirectional communication technologies that use HTTP as a transport layer to benefit from existing infrastructure (proxies, filtering, authentication). Such technologies were implemented as trade-offs between efficiency and reliability because HTTP was not initially meant to be used for bidirectional communication (see [RFC6202] for further discussion).
...
Basically [websockets are] intended to be as close to just exposing raw TCP to script as possible given the constraints of the Web. It's also designed in such a way that its servers can share a port with HTTP servers, by having its handshake be a valid HTTP Upgrade request.
...
The WebSocket Protocol is an independent TCP-based protocol. Its only relationship to HTTP is that its handshake is interpreted by HTTP servers as an Upgrade request.

[jade garden]

Oh, thank you so much!

[prisma cobalt]

one thing to note, a TCP socket is stream based whereas a websocket is message based (something to consider if using normal sockets)

[hasty quest]

Sockets are an API for several basic network protocols

Most commonly TCP and UDP

They're basically the most primitive part of the network stack you'll ever interact with, unless you're doing something weird or writing the netstack for a kernel. You use them to do things like implement HTTP servers from scratch.

It's not really correct IMO to say that HTTP is an abstraction over sockets

HTTP is a protocol which is built on TCP

It's not really an abstraction over that either

It is made from TCP but I don't think that's really the same thing.

[jade garden]

I see, thank you!
Yeah, I think the person said "built on top of" and the "abstraction" part is my own misunderstanding

[hasty quest]

so TCP basically exists for the purpose of allowing two applications to transfer binary data to eachother in a file-like way

one side sends "some data", that data becomes available for the other side to read

this is extremely primitive. It exists so that other, more structured things can be made out of it - these things actually depend on the shape of the data, and HTTP is one of these.

[jade garden]

[hasty quest]

HTTP gives structure to a binary data stream

An HTTP request has a clear format and size

It always starts with a request line, and headers. These are delimited using special byte sequences. And one of the headers is used to delimit the rest of the request.

So given a binary data stream which contains any number of requests, you can always tell where each one starts and stops, as long as you're following the rules.

Something that's important to note is that there is no direct mapping between "number of HTTP requests" and "number of TCP segments"

[jade garden]

And delimit means that this header tells you how long the HTTP request is? (that is, how many bytes it contains)

[hasty quest]

yeah. Content-Length is the length of the requsts body

The two protocols operate independently. One HTTP request could span multiple TCP segments. Or one TCP segment could contain multiple HTTP requests.

Check out the TCP IP Guide for more on this topic, it's free to read online

[jade garden]

I will, thank you!

Oh, it has a whole section on "Networking fundamentals", nice. Seems like exactly what I need

[jade garden]

The only thing I'm worried about is it's old, seems to be written in 2005 but I assume the fundamentals that I will learn as a beginner haven't really changed

[hasty quest]

most of the protocols in question predate 2005

It is slightly old but most of it still applies

[jade garden]

I see, thank you!

why can't you just connect your wifi to your pc normally like i would on a phone

[rugged fern]

hey guys anyone knows how i can host my flask app on my local machine while still accessible on the internet by other users? I looked online and couldnt find a specific solution

[prisma cobalt]

@rugged fern you'll probably have to setup port forwarding, see: #networks message

[rugged fern]

hey i sent you a dm

[prisma cobalt]

could we keep it here?

[rugged fern]

sure, so i looked into it and first i had to reserve the ip address for my pc so that it doesnt change in the future

I set the protocol to both cuz idk if it should be tcp or udp

[prisma cobalt]

a static private ip is a good idea but not the biggest issue

that looks good

assuming you're ona standard consumer plan with your ISP, your public IP address is liable to change every so often which makes it very difficult for clients to connect to your machine, you can solve this either by buying a static ip from your ISP (if they offer them) or configuring DDNS

[rugged fern]

ohh

[prisma cobalt]

first though, is the port forwarding working?

[rugged fern]

I havent tested it yet, should i just replace localhost with my public ip?

[prisma cobalt]

yeah that should do it

[rugged fern]

hmm its not working

it could be my ISP not allowing port forwarding

[prisma cobalt]

usually it's a router setting which appears to be this. if this rule was saved correctly it should™️ work

make sure to include the port in the url

[rugged fern]

I did

should i set a DMZ IP address

well its actually not even working on my own pc

wait, it might have been because i was using the wrong ip address

[crystal current]

Heheh, that's important

If port forwarding ends up being troublesome or impossible, the alternative is to use a tunnel. Cloudflare is nice and easy but you have to register a domain name with them to use it. There are more open alternatives like Ngrok but I've never used them personally

Easily most common mistake I've seen from cloud beginners 😉

[fallow jasper]

Anyone know how fix ssl error 1000 on a windows 2012 r2 server when trying to run a discord bot ?

[shrewd kite]

I would like to profile network usage and build something like a flame graph for code paths that emit or recieve on the network.

Anyone know how to do that without too much trouble?

[crystal current]

https://pyflame.readthedocs.io/

[shrewd kite]

@crystal current How does pyflame profile the network? AFAIK it's a sampling stack profiler, not a network or memory profiler.

The issue with network profiling seems to be that you need to setup some kind proxy, socket, or container, and count the packets across that boundary... while also attributing packets to the program's stack samples

Hey, how can i use Flask to initiate a DHCP Connection? is it possible to do it?

[hasty quest]

DHCP is connectionless, there's no such thing

I can't really tell from this description what you're trying to do

If you just want to do DHCP things, you can use a library for it. Doesn't really have anything to do with flask, but there's no reason you couldn't call a routine dealing with DHCP from a flask endpoint handler

[tall wadi]

Nope, I want to integrate it with flask

[hasty quest]

integrate how?

[tall wadi]

wait, lemme show

[hasty quest]

I mean no matter what you're doing it's basically a matter of gluing the two different functionalities together, using the appropriate libraries or software for each.

https://github.com/javimoral/flask-isc-dhcp

[tall wadi]

@hasty quest

Nothing complicated, i just want something like this -

when i click on the "Connect all devices" button, it should show me a list of devices connected via DHCP to my laptop, and my router ats like DHCP server. That should be it

[jade garden]

Reading the TCP/IP guide, turns out this networking stuff is really interesting

[tall wadi]

Nvm, I dropped this, its not necessary now @hasty quest

[tiny condor]

Does anyone know why I can connect to a websocket with cloudfare via an online websocket connnection website but not using the websockets library in Python and how would I fix it?

[cedar forum]

going to need some more than that

code samples and error messages would be a good start

[lyric oak]

1. You do need to find a TCP/IP book and correct the misunderstanding of DHCP. There is never "a list of devices connected via DHCP to" either your laptop, nor the the router even if it works as DHCP server, because like others pointed out DHCP is over UDP and connectionless. 2) Your other wish to collect which devices talked to the DHCP and acquired IP addresses is only possible if your router opens up that via some protocol. This is vendor/device specific. Some go through SNMP, some through other protocols, and others might even not have such an interface for you to integrate with.

[lyric oak]

You will have to flip a few settings and see whether things start to work. Some WebSocket servers do not support compression or other features, but the Python library you use might enable such features by default and then fail to create connections.

[tall wadi]

[coarse summit]

Huh can you re explain

[tardy dagger]

I just got started into Networking

This is pretty cool not going to lie

[umbral shore]

Well this is a loaded question for sure.

Are you connected to an ethernet cable? How much bandwidth does your isp allocate to you? Is your pc old, is the network chip updated? How far away are you from the router or hub if not connected via ethernet?

Many more questions i could add to that. If you want people to help you, be specific because most people won't take time out of their day diagnosing a black box issue.

[finite bay]

I did a self installation of a modem. I plugged the coaxial cable into the coaxial outlet as well as the power cord to the power outlet for the modem. The green light keep flashing. Could it be that I don’t have a router yet and I haven’t plugged the Ethernet cord into anything?

Or the green light shouldn’t be flashing regardless?

[crystal current]

We don't know your modem and we don't know your ISP.

[finite bay]

Sagemcom F@st and Cogeco

[finite bay]

Any ideas?

[crystal current]

Plug in a device and if it still doesn't work, ask them?

It's pretty normal for you to need to contact your ISP when installing a new modem. They register the MAC or whatever they do manually. Plus you need to check if they support your device, right DOCSIS version and all that

[stiff pagoda]

Hmm im using flask and websockets, firewall disabled so what is the reason if server is running?

from flask import Flask
from flask_socketio import SocketIO
import socketio

app = Flask(__name__)
socket = SocketIO(app)
sio = socketio.Client()

Server is using socket, client sio

Error

Failed to establish a new connection: [WinError 10061] No connection could be made because the target machine actively refused it'))

SS from server machine

SS from client machine

[broken sorrel]

Looks like server is only listening on 127.0.0.1 - you’re connecting to a different IP so even if it’s the right machine, it won’t connect. Try having the server listen on 0.0.0.0

[simple kettle]

I've been asked to decrypt tls packets recv by sockets, now I am in bad headache🤣

only thing I have is an useless pem certificate

[stiff pagoda]

Thanks it was it!

[obsidian crag]

In sockets you have two clients on two seperate namespaces “x” and “y” how do you connect x to y without the interference of the server as a proxy. Example, transferring audio data, should transfer from y to x on x’s request to the server, y starts transport and the data is directly given to x without server interaction (to not proxy the data, it causes overload in high volume)

[neat jolt]

Hi everyone! I've worked lately on a game with sockets. Today, I found this article about basics of thread locking that was helpful for me cause I wasn't sure what thread locking was. Maybe there's someone around with some questions about it so I just want to share my findings.

        if response.status_code == 200:

basically i know shit about cyber security and I have to make a Comprehensive Web Application Fuzzer.

so I'm taking chat gpt help can anybody help?

[crystal current]

Ask it to explain the code for you line by line and it will

But essentially that function will check for a URL based on each word in the word list and let you know which, if any, of those URLs exist

Hey, for any 5G cellular network, is it wrong to use the handover data for research purposes? is there any open sourcr data available?

[tardy harness]

Is it possible for me to tunnel my internet connection through Facebook if my internet service provider gives me free unlimited access to Facebook?

[compact mist]

Lol love this idea

[tardy harness]

There are a lot of people working with this method

[ocean bay]

wouldnt you have to connect to their router

[compact mist]

Already doing it? If so then the answer to your question is yes. Otherwise, maybe. Probably also violating the rules of the server.

[tardy harness]

No, that's why I am asking.

[crystal current]

No, if you could proxy traffic through a third party like Facebook at will, that would be a major security flaw

[tardy harness]

In my work zone the internet blocked only whatsapp works, but when I use this tunnel app and choose wahtsapp bundle allow me access to the internet , could you clearify it for me please.

[crystal current]

I've never used this app and know nothing about it, but apparently it provides ssh tunnels? So what's the question? If you're asking how to access Facebook,.I would assume the Direct Internet option works?

If not you should probably find their support forum or something

[brazen ferry]

There's CDRs on Kaggle https://www.kaggle.com/datasets/marcodena/mobile-phone-activity

[tall wadi]

ohh

[lyric oak]

Developers of such solutions can encode/decode raw data on both sides and choose any other protocols as carrier (not necessarily SSH/SSL). The one you referred to probably uses Whatsapp messages to bypass the ISP limits. While you can create the same, the implementation isn't trivial.

[tardy harness]

How I can create the same, also another thing need to know that's ISP gives an offer to unlimited youtube and whatsapp for one month but after few days they cheating on the users with reducing yt speed to 200kp/s.

[lyric oak]

Quite similar to creating your own VPN client/server, for which search engines might give you good references. Too much for a quick chat.

[tardy harness]

Ok, what about the second question ❔

[lyric oak]

Bandwidth is usually controlled by ISP devices, so your only option is to escalate to them.

Where can I learn computer networking to such an extend that will help me configure docker networks properly.
My main idea is to learn networking in such a way that will cover fundamentals and adavance topics for networking which will help me understand docker networking.
Documentation/blogs are my priority, videos suggestions are also okay.

[crystal current]

You will probably have a better idea of what fundamentals you may be missing if you focus on specific projects and problems. Docker in itself doesn't assume much network knowledge.

That said, ConpTIA Network+ study materials cover more than what you really need. Maybe read through the official exam objectives and if you're missing certain things you can read up about them or check Professor Messer's free videos

[sinful snow]

Okay Thank you so much for the help

[atomic orbit]

Let's say you have a LAN with 3 subnets. Let's then say that in Subnet1, you have computer1 and computer2, and on subnet2, you have computer3. If you have mDNS configured in all 3 computers, only computer1 and computer2 would be able to communicate via the mDNS, right? (Since computer3 is on a different subnet, it wouldn't be able to communicate with computer1 and computer2?)

Hi! I'm happy to share with you guys that after battling a lot with sockets and streams I could finally connect two players and a server and transfer data between them in json format to play blackjack. This is something to be shared here, friends and family would only frown if I told them

[ember ledge]

oi. question for my barematetal server-at-home folk. i have a linux machine, a windows machine and possibly a mac machine in the near future. i want to be able to share files between all of them and back them up with at least some little level of safety. my boss told me that 3 is the magic number of backups and thats what people use at google. but i was thinking about a RAID 10 NAS instead. 4 bays holding 2tb NVMEs. one drive would be personal stuff, one drive would be work stuff and the rest would be mirrors. the problem im imposing on myself is that i would like it to be fast too... so 1gigabit wont cut it because im telling myself that it wont, not because this is fundamented in anyway. ive just watched too many LTT videos. does this configuration make sense? if 1gigabit is too slow, is there some type of docking station out there with a 10gigabit connection? cause i can get the card onto the PCs but no way im opening my laptop to install another network card. so docking station + thunderbolt usb-c seems like the way to go. if this is all a bad idea, just crush it and give me a better one?

(about the drives, theyre gonna be all exfat. same model. about personal stuff, that includes pictures of cats, game files, and possibly some self-hosting)

I think network describe my problem at best.

def send_input_to_server():
    while True: PROBLEM IS HERE
        if pygame.key.get_focused(): 
            keys = pygame.key.get_pressed()
            if keys[pygame.K_w]:  
                client_socket.sendto(b"UP", (SERVER_IP, SERVER_PORT))
            elif keys[pygame.K_s]:
                client_socket.sendto(b"DOWN", (SERVER_IP, SERVER_PORT))


# Hauptprogramm
def main():
    # Thread zum Senden der Inputs
    input_thread = threading.Thread(target=send_input_to_server)
    input_thread.daemon = True  # Thread beenden, wenn das Hauptprogramm beendet wird
    input_thread.start()
    ......

Can I set a delay in a threaded function? Because if I press a key, the loop is too fast. So too much sendto(....) will be runned by a simple press and release for under second

Is there only the two cheap ways? Read the time of OS and add some time or use a for-loop that just calculates an variable with += 1.

[grand kayak]

I didn't understand that well those two ways you described.
However, the one approach that came to mind was: https://stackoverflow.com/questions/43503995/pygame-key-get-pressed-how-to-add-interval

Does this help you out in any way?

[umbral shard]

I think yes, but does this also work if the function is threaded?

[grand kayak]

yes, but you will need to have a dictionary mapping the thread id to its individual value for "getCurrentMillis".

or some solution similar to this

Recruiting conflicts with this server's guidelines

[jade garden]

Currently learning requests (Python library) and learning the basics of HTTP requests in general, for some reason I find this much more interesting than I expected

[frigid cradle]

boys, is my understanding correct that this is solely local and i launch the receiver server on another device thats not on the same wifi it wont work?

if so how do i make it public

plug in some kind of public server, but can i somehow i make the senders computer be that server

bcs the implication is p2p messanging

[steady horizon]

Binding to a loopback address doesn't expose your server to any other entity, not even ones in the same network. You would need to bind to socket.gethostbyname(socket.gethostname())) to expose your server to at least other entities in your local network

[frigid cradle]

thanks a lot, that worked

[spice jay]

what is zmq

and i dont think sockets are good

i mean you cant use them outside your local net

[limpid girder]

someone knows how i can expose my pi zero to the internet?

[steady horizon]

Probably the same way you would expose any other machine to the internet

Port forwarding yada yada yada

[limpid girder]

i added a port forwarding profile already#

but what should i do now

[steady horizon]

If your pi only needs to send out requests and receive their responses, you don't need to set up port forwarding

[limpid girder]

nah it should be a socket server

[steady horizon]

Now you should be able to accept incoming requests on a port of UDP/TCP however you set up

[limpid girder]

yea, but i wont work

[steady horizon]

Are you binding to (socket.gethostbyname(socket.gethostname()), the_port_that_is_open)?

You need to bind to the matching local address and port you defined when setting up port forwarding

[limpid girder]

i am binding „0.0.0.0“, 9999

so yeah

[steady horizon]

If that port number is correct than maybe you set up UDP accidentally instead of TCP or vice versa

[limpid girder]

do i have to setup the Port forwarding at the pi too or just at the router

[steady horizon]

It's a locally served page you can access via a web browser

usually

[limpid girder]

hmm

okay i did that but

idk whats the prob then

[steady horizon]

Well I'm going off with 0 error tracebacks

If it's a TCP socket, did you call socket.listen?

[limpid girder]

my code is working but when i try to Connect to that Server without beeing in the same network it just cant Connect to that

[limpid girder]

yeah

my problem is not the code

just the thing that i cant reach my pi about the internet

[steady horizon]

Wait how is your client trying to connect to the server

You're supposed to use your public IP address for that

[limpid girder]

ik

there the prob

[steady horizon]

So does it work now?

[limpid girder]

nope

[steady horizon]

I thought you changed it from whatever IP address to use the public IP address

Are you using the right public port number?

It can be different

[steady horizon]

You can only check this in the port forwarding configuration you set

[limpid girder]

ah okay

wait

where can i see that

[steady horizon]

Okay it is set to 9999

[limpid girder]

yeah but wheres the public ip

[steady horizon]

You can look it up with a Google search

[limpid girder]

bro that was the "google search"

now am confused

[steady horizon]

Go to like aws.whatismyip.com and you'll see the IP address your clients should be connecting to

[limpid girder]

bro thats the ip on the img before

[steady horizon]

Supposed to be the pi's IP address in the local network

For communication within the local network (includes the router)

[limpid girder]

nah

[limpid girder]

in that img m8

[steady horizon]

I don't know what ifconfig.me gives but that may very well be your (router's) public IP address

[limpid girder]

but thats it

[steady horizon]

So are your clients connecting to that?

[limpid girder]

😢 ....

nooo

[steady horizon]

I don't know how I can help you further without seeing your client connection code

[limpid girder]

its just that for testing a connection:

import socket

server = socket.socket().connect(("95.91.234.163", 9999))```

[steady horizon]

Should be

from socket import socket
SERVER_ADDRESS = "95.91.234.163"
SERVER_PORT = 9999

with socket() as client_socket:
    client_socket.connect((SERVER_ADDRESS, SERVER_PORT))

What error are you getting with this?

[limpid girder]

same error as before

[steady horizon]

Which says what?

[limpid girder]

connection timeout

and bro thats literally the same code as mine just prettier

[steady horizon]

What if you change SERVER_ADDRESS to "192.168.178.63"

And use the same network

[limpid girder]

then its working

[atomic orbit]

without using a third party package like zeroconf, how can i send an mDNS query to devices on my local network (and get a response)?

“Everything looks good to me”

Implement the protocol again by yourself? So, what's the point of using Python without "third party" packages?

[atomic orbit]

i cant use third party packages as a requirement. would something like this be as simple as constructing a UDP packet and sending it to the broadcast address 224.0.0.251 on port 5353 and seeing who responds?

[lunar marsh]

i have a doubt why is the Domain names paid. from where are these websites like Namescheap and Godaddy brokers us domains

[edgy pelican]

someone owns a TLD right

(a tld is like .com, .net, .org, etc.)

(i think) they allow such services to sell domains with the TLD

with a licensing fee

[lunar marsh]

oh

[edgy pelican]

lets say i own .hello

i can allow this person to sell domains that have a .hello TLD

and they pay me money

[lunar marsh]

oh so its just for uniformity and the process of hosting this dns stuff we pay money to these brokers which give us .org .com stuff

like i did'nt see any other websites like .hello or something .com .net all are very common and uniform among all sites

[hasty quest]

ICANN have a monopoly on deciding which domain names exist and who gets to use them. In exchange for a shitload of money, they will say that your company gets to be in charge of some subset of all possible domain names.

Your company then charges other companies and people, and they'll say you're in charge of some domain

Hello everyone! I'm working on an automated system to play this ctf. Basically I'm using paramiko to connect through ssh to copy a python script, run such script and create a password from the result.

I've tried to implement this solution but it didn't work, also tried fabric and same luck.

[gentle trench]

Sent some message to a local tcp server, and it sent some extra bytes along with the message. What are these?

[grand kayak]

You mean the 0d 0a at the end? Or the stuff before your message?

[gentle trench]

before and end both

[gentle trench]

When an app stops listening on a port, it remains bound for a while. Why was I able to bind a new app to the same port immediately after closing the first one

[grand kayak]

0d 0a is a line break, your message possibly ends in a \n.

The bytes before your message are the headers of the ethernet, IP and TCP protocols, in that order.
They contain the source and destination IP addresses, source and destination TCP ports as well as lots of other information so that your message gets to the correct destination intact.

[gentle trench]

Oh ye I thought this was it

[gentle trench]

Wbt?

[grand kayak]

What OS are you on?

[gentle trench]

Windows

11 if that matters

[grand kayak]

I'm not 100% sure on that one. But my guess is the network layer on your OS prioritizes a process requesting to listen on a port over the old one which has stopped listening.

[gentle trench]

O_o 👍

[steady horizon]

Maybe close() frees the socket for other programs to use immediately

[brazen ferry]

I've used Lucid Charts, and even Visio in a previous job. I'd also be interested in any mermaid/markdown compatible options

[proud swift]

Where does it say it remains bound for a while?

Do you mean the TIME_WAIT state?

[gentle trench]

TIME_WAIT or CLOSE_WAIT one of these

I am not sure which one was which

Hello

#cybersecurity message @flat arch
You can implement your own protocols using raw sockets in different OSI layers. It's not harmful or anything because recipients who are unable to communicate in it will simply ignore its packets

[flat arch]

But what if I want the recipient to understand my protocol, how can I do that?

@steady horizon

[steady horizon]

You'd implement the protocol on your recipient's machine and make sure that implementation runs

The only difference between doing that and implementing protocols over TCP/IP or UDP/IP is that there is no specialized hardware component that would run your implementation for you. You'd be running it on the CPU like a program

I'm not sure where to even begin, as wlan0 doesn't even have an IP. sh dan@raspberrypi:~ $ ip addr 1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000 ... 2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP group default qlen 1000 link/ether d8:3a:dd:e8:15:8a brd ff:ff:ff:ff:ff:ff inet 192.168.10.102/24 brd 192.168.10.255 scope global dynamic noprefixroute eth0 valid_lft 84170sec preferred_lft 84170sec inet6 fe80::5480:8b26:5310:8113/64 scope link noprefixroute valid_lft forever preferred_lft forever 3: wlan0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP group default qlen 1000 link/ether d8:3a:dd:e8:15:8b brd ff:ff:ff:ff:ff:ffand my routing tables:sh dan@raspberrypi:~ $ ip route show default via 192.168.10.1 dev eth0 proto dhcp src 192.168.10.102 metric 100 192.168.10.0/24 dev eth0 proto kernel scope link src 192.168.10.102 metric 100

Fwiw I have set the network in /etc/wpa_supplicant/wpa_supplicant.conf though I assume it's not connecting since ethernet is plugged in

whats this websocket issue

bruh

[stiff pagoda]

Easiest way to get ssl working for flask socketio based app? I would love to use adhoc but it doesn't work correctly...

[edgy kettle]

Maybe put it behind a proxy? Caddy works well for SSL setups, it handles Let's Encrypt certificates automatically

[analog shadow]

A 426 error, also known as "Upgrade Required," is an HTTP status code that indicates the server requires a specific upgrade or a different protocol to process the request. In other words, the server is telling the client (your browser or application) that it needs to upgrade its protocol or request method to access the requested resource.

[gaunt flare]

Alright thank you

Ill see what i can do

[ember ledge]

Hello Everybody

[sturdy breach]

Welcome! do you build neuro networks?

[ember ledge]

I do a sorts of that, but I am currently focusing of penetration testing and building servers from scratch.

[sturdy breach]

Woah, you went the other way haha. do you have a plan in mind youre trying to execute?

[ember ledge]

I am trying to secure my new server with using multiple VM on my laptop. The original idea was to try and make each virtual machine attack each other on my computer locally( with adjacent ai to help it of course) to see the weaknesses in each VM. But then I had an idea of creating a web UI for each VM so that I can execute code or work on features of that specific VM. The final goal is too get all VMs working in tandem for testing, counter offensive attacks, defensive attacks, and rewriting of code for defense.

@sturdy breach It is just an idea and I am about 5% done with the project.

[full roost]

hi

is this the support chat i am having issue with google colab

[fading quest]

Hi, iam trying to sneak into a MAN network in my area, which allows only one device at one time for 30 days (pack). They give password.

And once the device is connected it locks the first device MAC address.
Even if u turn on the hotspot of that device it won't let another device to connect. It directly takes to the login page and by adding same password it show it wont connect for this device...

No matter whtever i try i lt wont allow me connect more than 1 device...

How to solve this???

[dull gate]

PlantUML is old but pretty mature and powerful tool

[edgy pelican]

!rule 5

[errant bay]

Rules

5. Do not provide or request help on projects that may violate terms of service, or that may be deemed inappropriate, malicious, or illegal.

[edgy pelican]

this seems extremely legally (and morally) questionable

[fading quest]

How so?

I am already paying for 1 device, which is worth for more than 5 members or private family wifi..

It's just in our complex they overcharging and cutting other competitors so they can rule and make money...

If i want to connect my phone and laptop then i have to pay double amount.

[sour patrol]

https://discord.com/channels/267624335836053506/1301572638468210739^
can someone help

[edgy pelican]

... then pay double?

overcharged things doesnt make it right for you to steal them

[gloomy root]

I mean you can probably do this without trying to bypass device limits things if you can configure a NAT gateway so your two devices route via the nat which is the main device connecting

That being said though the words "Free wifi" as your general means of connecting would probably warrant also setting up a VPN configuration while you're at it... Since any managed network like that can be pretty sketchy

Also other less annoying alternatives include:

• starlink
• 4/5g cellular wifi routers

[frosty creek]

lol I managed to get GPT to print its IP adress, is it valueable at all?

[hasty quest]

use 50 mpbs
not stealing

use 50 mpbs, but differently
stealing
????

It's all bandwidth lol

Downloading 50 gigabytes on one device and 50 on another is not any different from downloading 100 gigabytes from the service provider's perspective.

They just want to charge you twice as much for literally nothing, because most people are stupid enough to pay them double for no reason.

[edgy pelican]

i mean they can just tell the netadmin to change it to charge by bandwidth ¯_(ツ)_/¯

but how they charge it doesnt affect its questionability (idk the word here)

[hasty quest]

I don't think it can even technically be really called theft of service

because for it to be theft of service, you'd have to be getting service that you didn't pay for. But operating two client devices instead of one is neither more service nor a different service.

[edgy pelican]

i mean

if i have 1 website

and put it behind cloudflare

i can't take another website and also put it behind cloudflare

even if i own the website

[rose vessel]

If you pay for the service and you're avoiding the terms and bypassing thats still theft. Imagine if you did that to your ISP to get your 100mbps connection to 200. That's theft still

[gloomy root]

Er what?

you absolutely can

[hasty quest]

200 mbps is a different service from 100mbps, so this example doesn't work at all lol

I don't think you actually read anything I wrote

Downloading 50 gigabytes on one device and 50 on another is not any different from downloading 100 gigabytes from the service provider's perspective.
Consuming twice as much bandwidth as you should be allotted is pretty fucking obviously different from the service you paid for from the service provider's perspective.

Consuming bandwidth within the limits that you paid for is not.

I have literally no idea where this comparison comes from.

[ember ledge]

How many collision domains and broadcasts domains are there?

5 collisions for the hubs, 2 for the switches?

and 2 because the router goes to 2 switches?

[fading quest]

Baka, they cheating us.

[fading quest]

How to do that?.

Okay, here's what i did.
There are two steps that were working but not very well.

1. I used reverse tethering from my phone to my laptop via a cable, which works perfectly on both devices.

2. I directly connected the router to the network, and it broadcasts Wi-Fi to both my devices and even more devices. However, the data(internet) doesn’t work simultaneously. If I use it on my phone, it doesn’t work on my laptop, and vice versa.,
   It stop for like 2-3 mins before connecting to other device.

[dusty lance]

for you to determine how many broadcast domain, you have first to know how many subnet in the topology

say left the left side is 192,168.1.0/24 and right side is 192.168.2.0/24
then there's 2 broadcast domains

and as for collson domain, how i do look it is
i dont really look at devices perspective

rather just count how many cable are there

although cable isnt really exactly right
as some LAN uses trunk port instead of access port

and iirc hub is differ to switch and router

like regardless of how many connection from hub are, theyre 1 collison domain

[dusty lance]

there are 7 collison domains total

[hollow jackal]

can i open different websocket connections to the same server in websockets library in python?

[fallow thistle]

sounds like they have that access point set for only 1 MAC address at a time. really no getting around that unless you spoofed the addres onto other devices maybe? but even then it still probably has the limitation of allowing only 1 MAC address for a connection

similar to port security configurations we use on our networking devices

[proud swift]

Yes

[burnt pulsar]

[burnt pulsar]

do you know how to stop tcp retransmissions or rst packets

idk what caused it

i just get a lot of them and my ping is double unless i use ip allocation and it knocks it back down to 50 or 60 but i can get eu ping on a na server

[opal crane]

hi i just learnt about vlans and subnet masks

I am lookinjg at recreating a network where i have a subnet mask of 255.255.255.192 for (2^2 networks, 2^6 hosts)

if i am correct the way this works is. 192.168.0.[1100000]

so i have 6 available bits for host assignment

this is my test network.
I have 3 VLANS
10 - Finance
20 - HR
30 - Management

this is my router on a stick network

if i want to assign each department their own vlan

do i assign it to PT switch 5

each port

or do i have to manually assign it to each port within PT Switch 3,6 and 4

[opal crane]

on top of that so i have assigned trunking ports to sweitch PT 5

to the 3 switches and the router

[native sapphire]

Hello everyone, I hope you guys are having good time.

I had this thought in mind, I have a fastapi application and I was thinking to host it on Mac Mini M4 .

Is it possible to do it in real life for real project or is it a stupid idea?

Please Advise.

[prisma cobalt]

it's not a stupid idea, it would probably work very well in fact as a cheap, self hosted solution

if it has an ethernet port, I'd recommend plugging it in so it doesn't drop connection but it's not neccesary

[dusty lance]

whichever switch is fine , in industry level , they even have says most of VLAN 10 on sw1 but some of the other of PCs that is part of VLAN 10 is on another switch, but make sure theyre still connected, and its usually bcuz of how their building are designed
as for trunk port
you can manually configure them or use DTP
but in enterprise level they dont use DTP for security reason sometimes

but you need to understand how the frame will travels and how the router will route the interVLAN's communication

[tight drum]

Hello, im trying to use a socket to send messages between computers but im having issues on the client side, code after the connection to the server isnt running. On the server side it is printing the connection fine so i know line 7 is working, but line 8 never prints to the console

(im very new to sockets so sorry if this is a dumb question)

[proud swift]

Hmm. Try using socket.create_connection? https://docs.python.org/3/library/socket.html#socket.create_connection

Also show your server code, and the output

i need sophisticated advice on networking protocols

[lyric oak]

To design your own protocol, to implement a protocol, or something else? Once the direction is revealed, the internet is full of good guides/tutorials to resolve the sophisticated part.

[dark kestrel]

Does anyone have an idea on how to install ($(LIBdir)/libhpl.a) on Ubuntu

[dusty lance]

which layer of the OSI model?

also i dont think new potocol would be come in handy like homebrew

[mellow sundial]

make server send me stuff while i reject it so it doesnt even count to my data limit @dusty lance

straight up drop packets

[rose vessel]

With Networking protocols are you talking about routing protocols or more like TCP/UDP?

[dusty lance]

yh

like shadow says

which one

[dusty lance]

if it something like TCP/UDP i think @rose vessel would be the right person

he have experience working in ISP
so, maybe he have the required understanding

i just can help if it something like OSPF/BGP/ a bit of EIGRP and layer 2 stuff

[mellow sundial]

no idea in just want to drop some packets to not count to the proxy network

[mellow sundial]

thats also interesting, i thought of making my own proxy network with 100k+ ip's. ipv6 fine

[dusty lance]

if it something like proxy,server,dns...tbh, i havent really dive deep on those stuff

[mellow sundial]

i just need bunch of ips

ill setup software myself

[opal crane]

please help me

i can send a packet from 192.168.1.254 -> .2.254

but not from 1.254 -> 3.254

show run is identical in all switched

router options are also identical for all sub interfaces

[dusty lance]

what is the point of double cables for each inter switch connection
redundancy ?

although i dont rmb EtherChannel

wait , do you even have trunk configured from switch1 and router?

[opal crane]

double the speed

you can combine up to 8 cables into an ether channel

let’s say each cable is 1gb/s

you now have 8gb/s

[dusty lance]

is it like load balancing?

you share the load

or what

[opal crane]

emm yes

redundancy too

and simply being able to send more traffic at once across the channel

as the bandwidth doubles in this case

however just because it can be used for load balancing

that does not mean that the loads are distributed equally across the channel

[dusty lance]

for layer 2 i just know trunking,DTP,Switch stacking,STP,RSTP,MSTP,private VLAN,Port security but i nvr knew this 2 cable interconnection even though theyre just single VLAN

hi everyone, im working on a project where i need to detect if someone is remotely accessing my system. One approach i thought was to check the background running apps if there is any suspicious software installed but that would not be sufficient as the name of the software can be changed. so is there any way how to detect if some is remotely accessing my system ?
and i want to detect in such a way that there should be minimal or no false positives

[paper venture]

wow you opening the hacker-network security gate here

so you can of course analyse your network traffic in userspace using tcdump or wireshark. you can also check processes and your ssh keys. then theres also the kernelspace. so that depends on your system. on linux you can use ebpf. that brings us to intrusion detection like suricata which is implemented in opnsense

i would advise you to use zero trust access and get rid of ssh directly

the cool thing about kernelspace network filters is that you can drop suspicious packets directly in kernel space before they even reach your apps

How ethernet wires prevent two way traffic collision, i.e. traffic from both sides at the same instant of time?

[urban depot]

Who here can explain this??

I'm experiencing a significant difference in download speeds between my PC (wired via MoCA (Coaxial Cable over Ethernet)) and my iPhone 15 Pro (connected via 5GHz Wi-Fi) while downloading an ISO file for VMware vCenter from an MSP in the US.

My PC over MoCA gives me: 406.8 Mbps download, 19.5 Mbps upload (measured), but the ISO download was only at 0.8 GB after an hour.

My iPhone 15 Pro (Wi-Fi): Downloads the same ISO at ~4 GB per 5 minutes, with measured speeds nearly matching the PC’s, if not, slightly lower than the speeds above.

Interestingly, other downloads (e.g., Steam games), bulk downloads on the PC are near-instant, so this issue seems specific to the ISO download. Why might my iPhone be outperforming my PC in this case, despite being on the same network?

[dusty lance]

what is the bandwith of your Iphone's WI-FI and your cable

would be the answer ig

they both are different link

hi
i'm using httpx to post data to an API
the request containes a file and some text

        response = await client.post(url=url, data=data, headers=headers, files=files)

the problem is, i have to encode the data to json so the API can read it
but if i do that, httpx won't include the file in the request
