found out that a random guy created an account on my cloud and managed it somehow to dump a 60GB file called "all_in_one.7z" into it(the account is limited to 10GB) and that file does not show up in the user table, should i take that serious or is that just a file with manupilated metadata or dmth like that?

hello! im essentially brand new to raspberry pi, my brother fell in love w them and has gifted me one to tinker w, but i am at school & didn't bring a microSD card reader, is there any way to connect to my pi without having to need any specific cables? I do have a small extra monitor that I can connect the Pi to.

wait but isn't rasperry based on it ?

Please help me in installation of Ubuntu 20.4.5 Server

I’ve looked into containers/oiling…ect but what is the best way to waterproof my project including the wirings, that is constantly exposed to water like the lake. I don’t want to risk breaking my Raspberry Pi thanks 🙂

Anyone able to help troubleshoot why the wifi doesn't work on this pi. I've tried about everything I can find and am now resorting to discord help. Ethernet works fine.

i have a small bot problem with my Minecraft Server, every hour bots try to join so the server starts (it starts on player join) so i read into ufw to block that ip from where the requests come and they are still going through the firewall 🤔 why?

Hi! I am trying to get a Raspberry Pi V2 camera to work at 1280x720 pixels @ 120 FPS - cropped to full resolution, but I can't get it to work at over 90. Has anyone had any experience in this area?

I’m looking to host pivpn and adguard home dns on 2 separate pi zero 2w’s. Is there anything that would be a major problem using pi zeros for these tasks? Pivpn is used by 7 devices And adguard is used by at least 13 devices

i bought around the end of November a new phone that phone battery should have a capacity of 5Ah but now, after a bit more than 1 month of heavy use the battery reports a capacity of 4651mAh, that equals a 7,5% loss! can that be true or is it just displaying a wrong value?

made a dns with freedns,added to machine with ddmpm client. pivpn -d shows that everything is cool but yeah tried it with mobile and wireguard and it doesnt work at all

So i was Running an MC Server but Couldn't get on the Server so i wanted to turn it Of but just Froze i dont know how to fix it but pls help (Ping me if you can help)

it just gave me back a another line

Hello World, I'm trying to install a netis WF2190 wireless USB adapter to my Raspberry Pi 4b with the 64-bit Raspberry Pi OS installed and it's been a while since I've played with drivers in Linux and I'm having some problems. When I plug in the adapter and run 'lsusb', I see:

Bus 001 Device 006: ID 0bda:8812 Realtek Semiconductor Corp. RTL8812AU 802.11a/b/g/n/ac 2T2R DB WLAN Adapter

When I run 'lsmod', I do not see the drivers for it, so I tried installing the vendor-supplied drivers for Ubuntu 16.04 for it, located at https://www.netis-systems.com/Suppory/downloads/dd/1/img/443 but I've run into some errors. When I install per their instructions, I get the following error:

make ARCH=aarch64 CROSS_COMPILE= -C /lib/modules/5.15.76-v8+/build M=/home/pi/RTL8812AU_WF2190_WF2561/RTL8812AU_linux_v4.3.20_16317_20160108/driver/rtl8812AU_linux_v4.3.20_16317.20160108  modules

make[1]: Leaving directory '/usr/src/linux-headers-5.15.76-v8+'

I gather this is because of 'ARCH=aarch64', so I did some searching and manually edited the Makefile to indicate: 'ARCH=arm64' per someone else's recommendation for a similar problem (here: https://github.com/Mange/rtl8192eu-linux-driver/issues/228) but now I am receiving the following error:

Could someone perhaps recommend a different driver package for the 8812au wireless chipset for my OS, or otherwise help me figure out the issue with manually specifying 'ARCH=arm64' with the vendor-supplied drivers? Thank you so much! 🙂

Hello, My RaspberryPi 4B was purchased July 2022. The microSDHC card was purchased a couple years ago, but had remained unopened until today. This microSDHC works for other purposes such as photography. RaspberryPi Imager is able to flash the card. However, when I put it into my RaspberryPi and power on, it fails to boot (I am setting up headless). When using an older 8GB card, the RaspberryPi successfully boots. The only problem is that it writes very slowly and I want to switch to my larger 32GB microSD, but this one won’t boot. I have updated EEPROM using the working microSD and tried recovering it using the RaspberryPi Imager boot loader option. Is anyone able to help? Thank you in advance!

Hi, I run in to the problem and I have tried everything what I could find in the google and my VNC still does not work. I am having error that says error getting private key from registry BigNumReadF. Any idea how to tackle that? Cheers Dan

Hello. I am trying to install an OS to a Pi 4B (1gb ram). I started with the official guide and used the RPi-Imager. I also pre-configured the SSID and enabled ssh to simplify things after. Once powered on it boots seemingly normal, act intermittent quick flashes, however it then seemingly reboots (red/power light goes out) and then the Act light blinks 9 or 10 times, a possible HALT mode. This happens every time the pi is powered on, on both, I later learned this happens with Raspbian Lite 64bit and Raspbian Lite Legacy

Hi, I making one application using ElectronJS. On that app my video getting lagging/freezing. For testing purpose I tried play that video on Chrome browser same issue facing in Chrome also. I tried with VLC, If I keep full-screen video is running proper but if it is not full-screen it getting lagging. Any idea how to fix? Is there any way increase performance of a specific application?

Said cam is then probably faulty and would blow other pcs.

<@661594563919740967> Thought I would move the conversation here as it’s getting lost in the general thread. Have you rebooted your pi since installing OpenVPN? This is a required step to be able to install the tunnel device that OpenVPN uses. Also, you will need to get or set a new IP address on the vpn tunnel.

so we're making project to monitor air and sound pollution on raspberry and we want to display the sensor data(real time) on P10 LED Matrix i need exact instructions on how to do it and also which components and sensors to use to make it possible

I don't exact cause of issue, which is why I need help. I feel like it's because of large files or something about overloading, but it doesn't seem to crash syncing small stuff, but when it's a gigabyte on my phone especially but also on my pc sometimes, it just kinda crashes, hard drive is still blinking, internet is also blinking, no response from ssh nor nextcloud server, it just times out, I have to unplug the system which is a risk and let it boot again to fix this issue. What could it be, please help, I don't think it could be a problem with the router, but idk

I installed Ubuntu 20.04 on this RaspBerry but when I try to download a program, like Google Chrome or whatever program I think about and try to install it, it says that the architecture (amd64) is not the one that I can run (arm64). I do not really know what this means.

Here's the code that the arduino is running, I wrote it myself:

I just downloaded the default rpi systen onto my SD card and when i put it in my pi everything goes great until the welcome screen flashes for about a second and then my rpi starts shining red and the screen turns off. Please help.

So, I’m gonna try and turn my Pi into a router using OpenWRT. But I want to use a WAP instead of built in wifi chip or wifi dongle. Would you just connect it to the WAP with a Ethernet cable, then connect the WAP to your main router? Anddd, how would you even setup OpenWRT to use the Ethernet cable to send/receive data?

Hi, im trying to make a small LAN website that i can easily modify, ive already gotten a small webpage up using ssh, apache, and filezilla which makes everything run smooth rn. I want to add a livestream of a usb webcam that shows a 720p ~30fps vid of my 3d printer. Ive researched a lot and found no results that allow me to do the same where i can edit server files using filezilla or smth similar to that (if someone could find me a solution like that, i would appreciate it. Anyways another solution i thought of is streaming my usb webcam to yt and embedding it on the site, so far i watched this tutorial: https://youtu.be/cRycXUIK07g and its exactly what i need BUT i dont have a raspberry pi cam. how could i get it to work for a usb webcam?

Im using a rpi 1 but have multiple rpi 1s if running both tasks is to much for the rpi 1. i unfortunately though dont have anything more recent or better. any help is appreciated, ty! ^^

Does this just mean the SD card is broken, or my rpi?
