[EN] Network bridge
« on: 2024/05/20, 10:42:28 »
I have Siduction computer running from 2017, hardware is from 2011 prior to 2017 it was Aptosid. I didn't have much of issues with either. Now i have newer hardware and I would like to continue using Siduction but I am unable to configure bridge, whatever I do following instructions makes network stops working. What information I should supply in order to get some help?

i used this guide within the past year and it worked as expected:

https://wiki.debian.org/BridgeNetworkConnections

Can you troubleshoot each step and learn where the failure occurs?

With the current systemd, systemd-networkd seems broken for bridge.
I had the same Problem

my nic has become a ip
my bridge was allways down, i can't get it up

Downgraded systemd to 255.5-1 (from testing) and my network is working again.

Interesting to see here, my systemd-networkd has been disabled (not deliberately), and the bridge and networking are working correctly.
