<div dir="ltr">We're currently looking into requiring 802-1x for all wired ethernet connections. We have a large number of Linux clients. Mostly slim laptops that don't have an ethernet adapter. These connect to the wired network using docking stations or usb to ethernet adapters. All Linux clients are deployed using PXE boot to deploy the company image. Problem is during the deploy process there's of course only the adapter used for the deploy availbale on the client. I can get the 802-1x settings added for this adapter as part of the deploy. But then I'm out of control. I can't control NetworkManager to setup 802-1x for the connection created by NetworkManager when the user connects to a docking station. Yes, unfortunately it creates a new wired connection. It doesn't use the existing one. I've looked into setting up connection settings in NetworkManager.conf. Unfortunately it only supports the 802-1x.auth-timeout setting. I've tried using a pre-up dispatcher script, unfortunately it don't pick up on adding settings to the connection profile. I've tried using 2 pre-created connection profiles that only list the type as ethernet and don't point to a specific interface. This works for Ubuntu 20.04 and 22.04 but not 18.04, nmcli in Ubuntu 18.04 requires specifying ifname when creating a connection profile. Is there some way to hook into NetworkManager whenever it picks up a new device and add the 802-1x settings for all new wired connection profiles? Best regards J Doe</div>
