Can I plug a cisco SPA303 ip phone directly into the ethernet port of a raspberry pi running raspbx?
I have got raspbx setup and running using a wifi dongle to connect to the router. The system works with the Cisco phone plugged into the router. However, the router is on the other-side of my house and ideally, as the raspbx is wifi, I would like to plug the phone directly into the pi and have it as one unit I can have anywhere in the house.
I have spent a painful amount of hours trying to set this up and I am sure there is a simple fix I am overlooking. Any ideas would be greatly appreciated.
Yes, you can. But you should setup static ip on phone or setup dhcpd server on RPi
Also some cisco phones have double ports(internal simpler switch inside). If so, you can connect one-by-one upto 8 phones.
There are several layers to take into consideration:
Link layer MDI/MDI-X detection of crossover/patch ethernet cable detection.
Static IP address for Raspberry Pi and a DHCP server for the IP phone
TFTP server to provisionize the IP phone
A peer in asterisk for the IP phone

Let me explain what I want to happen.
I have an http server program that displays a website every time I connect to my raspberry pi's ip address on port 8080. But this only works on my current network. I want to be able to access this raspberry pi from any network by typing a website address. How would I connect my URL to this raspberry pi so that I can just type the domain and it will take me to my raspberry pi?
P.S. I have already tried searching for this extensively, but none of the results fits my needs
Thank you in advance,
Nick.
Assuming that your current network is your home network and any network is the internet as such, I think your question points into the direction of dynamic DNS (DDNS).
DDNS allows you to assign a fixed domain name to the (usually) varying external IP adresses of your home network.
This would make your PI reachable to the outside world.
Search for DDNS providers.
A couple questions.
TLDR is sending UDP broadcast packets on a Wifi network to allow for discovery of a IoT device (Raspberry PI) a conventional practice?
Long version: I'm working on an IoT project for a class. Based on other IoT devices I've used (a Christmas carol lighting system and music player), we decided to utilize an already working application (https://github.com/balena-os/wifi-connect). The way it works is it runs on the Raspberry PI and hosts a wifi endpoint through the RPI's network card that the user can connect to. Once a user connects to this Wifi endpoint on his/her Iphone, a Wifi selection and password entry page appears on his/her Iphone. The user enters the Wifi/password that the IoT device (Raspberry PI) should connect to. The entered Wifi will then be connected to by the Raspberry PI. The user can then connect to the entered Wifi as well and now both the user's Iphone and Raspberry PI will be connected to the same Wifi network.
We decided to send UDP packets to the broadcast address of the Wifi network from the IoT device, so that users connected to the Wifi (via their Iphones) can "discover" the IoT devices IP address by listening for UDP packets. Once the user discovers the IoT device's IP address, they can send HTTP RESTful API calls to the IoT device. I was wondering if the described process is conventionally used.
# script we are using to send UDP broadcast packets
import socket
import time
server = socket.socket(socket.AF_INET, socket.SOCK_DGRAM, socket.IPPROTO_UDP)
server.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEPORT, 1)
server.setsockopt(socket.SOL_SOCKET, socket.SO_BROADCAST, 1)
server.settimeout(0.2)
message = b"message"
while True:
server.sendto(message, ('<broadcast>', 16123))
time.sleep(1)
We tried this setup at a public library, using their free public wifi. However, the UDP broadcast packet discovery process failed. UDP broadcast packets were sent out by the IoT device, but were not received by the Iphone. We're wondering if this has something to do with a firewall. We could successfully send UDP broadcast packets from a Macbook (via a python script) to an IOS emulator residing on the same Macbook, such that the source IP address of the packet was the same as the recipient. Is there a firewall rule such that a broadcast packet sent from IP address [A] can be delivered back to IP address [A] but not to IP address [B].
Also, I didn't mess around with the port number, which might have helped if certain ports were disabled by a firewall. I'm not sure. Help is appreciated. We are both relatively new to this.
DNS-SD (RFC6763) is the a fairly common and standardized way to do network discovery. It actually supports both TCP & UDP services. It was originally invented by Apple under the brand name "Bonjour" for printer discovery.
So yes, it is common to use UDP broadcast packets (via DNS-SD) for IoT device discovery on a Wifi network.
The installation is in a holidays house (so no permanent internet access)
I have a 4g-Routerm (ROUTER-1 = huawei B525-b23) that enable the internet access. I switch it on one day a week.
I have another router (ROUTER-2 = GL-MT300N-V2).
ROUTER-2 is always plugged on electricity.
On ROUTER-2 is connected through ethernet port a Raspberry-Pi3 (with Home Assistant on it).
On ROUTER-2 is connected through WIFI a Camera IP
ROUTER-1 and ROUTER-2 are connected together through ethernet.
When ROUTER-1 is not plug to electricity, none have acces to internet, but it's not an issue.
The camera save picture on the Rapbery Pi3, the Home Assistat is recording some sensor data.
When I switch on the electricity on the ROUTER-1, everyone have access to internet.
What I want is to have remote Access to my router-2 and my Rasberry and my Camera when ROUTER-1 is online
How should I do ?
Hi I can think of two solutions for this setup but both involve buying a second hand cheap router.
I think the use of a single router would make this setup a lot easier. Any router would work that supports:a USB 4g Modem to be attached to it, and has support for setting up a openvpn server and you need to be OK with leaving the Internet on all the time just make sure you dont have any services running that use up bandwidth and you should be ok. You can can connect both raspberry pi and IP camera to that router. Setup Openvpn server open the UDP port required and download the certificates, You should be able to vpn into your network and manage it through SSH or something remotely.
The second option is tailored to you but still requires swapping the 4G Modem with another one that supports these things: Wake on LAN, openvpn server, supports ssh into it over LAN and either has 4G support through a sim card slot or a usb port with modem support.
You can then have it setup so this new Router-1 is switched off with wake on lan configured on it and the raspberry pi to send the magic packet. You can use something like this to get an idea of how WoL https://www.lifewire.com/wake-on-lan-4149800. You can use cron on your raspberry pi to send WoL signal to Router 1 once a week which would eventually give you internet access once the router is up. You have to setup a vpn server on it and forward the required port and download the certificates. When your scheduled WoL cron runs make sure you are able to connect through vpn then access network resources you wish, at the end when you are done you can ssh into the router-1 and turn it off.
I hope this helps. I had a look at the router models you are using and it doesnt leave you with many options. You can get cheap second hand routers online that support everything that is required.
I have a raspberry pi 3 connected to my PC (Windows 7) via ethernet using DHCP server and VNC viewer and it works perfectly.
The pc is connected to a WIFI.
I want to access to internet from my raspberry pi, I tried the ICS sharing but it didn't work:
I shared the wifi connection:here
changed the ip address: here
after sharing the wifi connection, I am unable to access internet from both the pc and rasp even though they are in the same ip address.
On PC,On the Rasp
Can you please help me to find a solution?
Thank you.
You have to create a network bridge.
Select the two networks, right click and select bridge connections.
I'd use static IP address on your PI and your PC's ethernet
I try to find the IP adresse of a Raspberry PI (LINUX) that is connected to the same Network as the iOS device my code is running on.
Is there some way to "find all" ip adress in the network the device is currently joined via SWIFT?
If you ping the broadcast address, unless devices are specifically configured not to replay, they will do so. How you do that with Swift is another question.
This question+answer will work if you know your IP address, you need to probe all the probable addresses of course.
