RPi internet issues with REXYGEN 3.0

MikeyH

Hi All,

I've just got a RPi 5 and installed Book Worm (64bit) on to it. I then used REXYGEN studio to bootstrap the runtime etc. Once I had done this, the pi lost internet access. I tired a few things but everything looked ok. I reinstalled Book Worm onto the SD card and started again. This time I used the manual RPi install method.

sudo wget https://download.rexcontrols.cz/partner/testing/rexygen.gpg -O /etc/apt/trusted.gpg.d/rexygen.gpg

echo 'deb https://download.rexcontrols.cz/partner/testing/rexygen/debian/ bookworm rexygen dwm' |
sudo tee -a /etc/apt/sources.list.d/rexygen-testing.list

sudo apt update
sudo apt install rexygen-runtime

This worked and internet access was ok, then I installed the dwm interface and it broke something in the internet settings.

Does the dwm install change network settings that might cause the pi to loose internet access?

Cheers,
Mike

@MikeyH Hi Mike,
the DWM uses systemd-networkd for network management. The default configuration for ethernet is in the /etc/systemd/network/eth0.network file:

[Match]
Name=eth0

[Network]
Address=169.254.0.100/16
DHCP=yes

that means that the DHCP client is allowed by default and there is the Windows fallback 169.254.0.100.

This default settings can cause problems if you are using static IP.

@Jan-Reitinger Hi Jan,

Thank you for the reply.

I'm not using a static IP, just DHCP on my home router at the moment. I've seen the changes DWM does with static IP, but have never seen it cause issues with normal DHCP. I've only used the Monarco image for a while now and have never had problems. This only seem to be when I use the bear raspberry pi command to install DWM.

Cheers,
Mike

@MikeyH Hi Mike,
We found out that there were changes to systemd in Bookworm. On the clean image, there is a problem in DNS after installing DWM. We will adjust the DWM installation accordingly so that everything works on Bookworm and older distributions. We'll let you know when we have a solution.

Cheers,

@MikeyH Hi Mike,
the DWM installation should now behave correctly. For Bookworm, the systemd-resolved package, which did not exist in previous distributions, should now be installed with DWM. We are sorry for complications.
