The answer is: it depends. In general: before you move, make a backup. In that way you do not loose any data. The rest depends a bit on how different the set-up will be in the new location and what the server actually does. If it is just an in-house server, and the IP plan is the same and the SSID/PSK are the same, it should just work. If anything changes,...

I found a solution with mDNS. The website I used is the following: https://www.howtogeek.com/167190/how-and-why-to-assign-the-.local-domain-to-your-raspberry-pi/ It worked perfectly fine.

Ubuntu Server uses Netplan to manage its connections. To create an access point using Netplan, you can do the following: 1. Install Network Manager sudo apt update sudo apt install network-manager 2. Disable cloud-init sudo bash -c "echo 'network: {config: disabled}' > /etc/cloud/cloud.cfg.d/99-disable-network-config.cfg" 3. Create a Netplan ...

It depends on your website and you should look for the size of that and its content. However, after the first model raspberry pi, it would be possible to run your website on a raspberry pi. Because the RAM capacity is reasonable and there would be no concentration about that. It's all about your internet capacity and your storage. If you intended to use ...

It should not be a problem to use OTG gadget mode on the USB connection to create an ethernet connection to your PC. It is part of the PC to route its internet connection to the RasPi and well known but out of scope here. Doing tethering with an android cellphone is working out of the box with the default Raspbian image. So it should be possible to use the ...

There are answers and comments addressing the question of why this probably isn't working and why it may not be workable as you're doing it now. Regarding the part of your question about how to work around it, I think the most straightforward ways would be either: Use a proxy with a VPN connection in between Send your data from the device connected via GSM ...

Get plain Raspbian Lite. That's ideal for a headless web-server.

With most providers you will get a private IP address, usually one like 10.x.y.z. This is not reachable from the internet. That is not necessarily to stop people from doing what you want to do, but to conserve public IP addresses. If your providers assigns IPv6 addresses, you may be able to use them. Otherwise, you can use a VPN connection to some VPN ...

OpenVPN is the service that is allowing you to connect from outside to your local network, basically a VPN server. By connecting to it, it creates a tunnel and your traffic is routed through it, and have access to your local network through the internet. The internal services, as in this case a HTTP Server, that you have on your network are not forwarded ...

I want more speed, I wanna be able to upload large files to my webpage quickly and I think USB 3.0 + External SSD with Exts4 on it will do the trick nicely. Mount your external drive to apache2 web files path. At first, find out what's the name of your drive on /dev: cat /proc/partitions | grep sd You might see something like this: 8 0 ...

I'm not familiar with MariaDB, but it's error message indicates that it uses case sensitive filenames and your filesystem does not support it. I suppose you are using a fat formated filesystem that uses case insensitive filenames. So you should either configure MariaDB to use case insensitive filenames (don't know if it is possible, look at the manual), or ...

Several posters have mentioned the importance of keeping your Pi up-to-date, but most resources I've found simply suggest manually running apt-get from time-to-time, which seems like a poor approach. I'd much prefer to have security updates automatically installed. The Debian unattended-upgrades package is supposed to support this, but (on Raspbian?) it's a ...

A code of thoughts: Python 3.7 is actually python3.7 (lowercase) or even python3 that may be the issue You may need to give a delay for the O/S to fully start Root may not have access to all the files depending on there location - cron jobs have very limited path settings. I would try: @reboot /usr/bin/python3 /home/pi/myscript.py 80 Sudo should not be ...

You do not tell much about your configuration but you say you are more interested to be pointed in the right direction. To look how OpenVPN works you can use a Simple openVPN with static keys. It keeps things simple because it doesn't use an asymetric key infrastructure. Here you can find some other examples: How To Create A Private Subnet Behind Raspberry ...

Unless it’s changed you can run PI-Hole itself on NGINX but any updates had a habit of defaulting back to lighttpd for the browser. There are a set of instructions (unofficial as of June 2020) here to configure the default site. Because of this you may need to look at how you run your script under a different site / IP address not used by pi-hole. I would ...

First thing to check is that your MySQL (or more likely MariaDB) server is listening on the INADDR_ANY (0.0.0.0) address. That needs a change to bind-address 0.0.0.0 in your config file. Then use sudo netstat -tlnpu | grep mysql to check that the mysqld task is running and listening OK. Next create a remote user as per the instructions at MySQL adding user ...

If you use the pigpio library and run it as a daemon on the pi, you can run local Python code that access the GPIO port on the remote pi. If you are new to this, you might also want to check out the gpiozero project.

The tutorial you linked is for Raspbian which uses dhcpcd as its network manager. Ubuntu Server uses systemd-networkd with a yaml front end. You COULD install network-manager (or dhcpcd for that matter) but you would be better to configure systemd-networkd. See Access point as WiFi router/repeater, optional with bridge (I have not tried this myself) PS ...

Web browsers work very hard to keep what happens within the browser from changing anything else on the computer running the browser. This is essential to maintaining security from malicious web sites. One way of doing what you want is to run a small server on the Raspberry Pi and have the web page, also running in a browser on the Raspberry Pi, send a ...

I found an answer to my own question - it's even official documentation. Right here is a guide of moving all data from SD-card to USB-device and then boot the boot files from SD bot all other files will be run from the SSD USB device.

Overall, I just want to visit (say) 192.168.0.1 (or whatever my Pi's IP is) on a local network and have my custom webpage show up. If you didn't change any config file of Nginx (I mean root section of /etc/nginx/sites-available), you can put your .html file into this location: /var/www/html In addition, read this simple documentation to configure ...

USB flash drives can reach up 33MBytes/s, but there seem to be some limitations in the NAND itself so it will come down to the type of stick you get. However, the sd-card bus speed can reach up to 20MB/s read on the raspberry pi. So, the better choice here is a high-class USB 2.0 USB flash drive. On the other hand, the payment would be concerned....

The SDCard interface is extremely slow compared to a USB 2.0 hard disk on my RPI3Bs. So a USB 3.0 SSD on a RPi4B is going to be even faster (USB 3.0 is faster, SSD is faster).

Which is better, SSD or HDD? Obviously, an SSD drive which has connected to Raspberry Pi 4B's USB 3.0 port. You can also fire up a simple web page and find a virtual system that hits a dozen connections to your site like this link. I thought that I saw another guy who built 8 boards together to server more traffic/visitors for his website. Of ...

The Flask framework is fine, your code has all the right logic and procedures as far as I can tell. But the structure (architecture) and control flow is not optimized for quick response or for multiple connections. The problem is that all the control logic (with hardware interactions) happens during the request/response processing. This is fine for a ...

so I was able to fix the issue by increasing the update interval. I guess on raspberry Pi, the interval needs to be larger in order for the chart to update correctly. Weird, but it works. Looks like its an ongoing issue with Dash.

You'll need to add more info before you get any good answers. For example, is the pi currently connected to any type of network? If it is, it should be straightforward to access a video feed its producing. (check out dataplicity ). If it's not, then you'll have to create a network for it to connect to, which is a different type of problem (buy a wifi ...

So, RPI is a computer and yes, you can configure your RPI to be an access point (and basically serve it's own wifi network devices can connect to). This may be a good start. It would not let your RPI wifi users access internet (unless you have another adapter that connects to network to bridge it) but it would work if you wanted them to connect to this wifi ...

The first thing I notice is that you wrote about https, but acording to the linked site, the web(cam)server on the pi supports http, only. Maybe, you give it a try? Test if you can connect to the server from within your local network, i.e. from your mobile when connected to WiFi by visiting http://raspberrypi:8081 (Maybe, you need to use the IP address ...
