I have assembled 1 PC with Ubuntu version 20.04.3.LTS.That PC needs to be used to connect to 3 cameras which are sending their data via an ethernet connection using TCP protocol for configuration and UDP for image streaming.So I equipped the PC with an ethernet network card (Link to the product) to have additional ethernet ports.I can configure each of them individually, 4 additional ethernet ports are visible (enp9s0f0/1/2/3) and they're all working perfectly individually :My Ubuntu Network Parameters
I have 3 cameras, they all have their own IP address which is configurable :
- 192.168.0.81
- 192.168.0.88
- 192.168.0.82
(They also have specific addresses which can be set for the UDP streaming IP address or the port)
I'm trying to make 2 cameras work together as a starting point.I have developed a program using an API to connect to those cameras and capture images which are sent via UDP protocol.Usually I only need to set a fixed IP to the ethernet port and by indicating the correct IP addresses inside my code, the API is able to grab data from the cameras.
I noticed that if 1 camera is connected, I can make things work without issues. But when I add an additional one on the network card, it will not be possible to connect to it.
The second camera that I connect on the adapter card is always visible but it will not answer to the ping command for example. It's unreachable.
I think it might be due to the fact that the cameras are on the same network subnet but I'm not really sure about this.
It seems that it can be solved by using some network table system but I'm not familiar at all with this.
Is it possible to make this work somehow ?
