Issues with bridge networking

[Ivan Klishch]

I'm trying to setup my cluster hat (on Raspberry Pi 3) and two Raspberry PI Zeros.

I'm using official images for controller and PI Zeros.

But after booting I see only lo interface and eth0 but it's not getting any IP address. I'm getting this error if I try to check my br0:

root@controller:/home/pi# ifup br0
add bridge failed: Package not installed
run-parts: /etc/network/if-pre-up.d/bridge exited with return code 1
Failed to bring up br0.

root@controller:/# modprobe bridge
modprobe: ERROR: ../libkmod/libkmod-index.c:822 index_mm_open() magic check fail: a3b941de instead of b007f457
modprobe: ERROR: ../libkmod/libkmod.c:557 kmod_search_moddep() could not open moddep file '/lib/modules/4.4.13-v7+/modules.dep.bin'

lsmod shows no loaded modules.

Hi,

 Sorry I didn't spot your message earlier, for some reason I didn't get notified.

It looks like something might have gone wrong writing the image as you should have the bridge tool /bin/bridge and there should be no issue loading kernel the module.

I would advise trying to write the image to the SD card again or try using an alternative micro SD card if you have one available.

Chris.
