I think I have hit this issue as the PAN does have ConfigureWithoutCarrier=yes https://github.com/systemd/systemd/issues/9479 ___ systemd-devel mailing list systemd-devel@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/systemd-devel

A bridge behaves like a virtual network switch, working transparently (the other machines do not need to know or care about its existence). Any real devices (e.g. eth0) and virtual devices (e.g. tap0) can be connected to it. ___ systemd-devel mailing list systemd-devel@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/systemd-devel
[systemd-devel] DHCP Server on multiple interfaces
Hi, Does systemd support the networkd DHCP Server on multiple network interfaces. I ask as we have an embedded system running systemd 239 and we want to configure a DHCP server on a bluetooth PAN and one of the Ethernet interfaces both of which are used for configuring the device. I've set up both the network files with [Network] DHCPServer=yes [DHCPServer] PoolOffset=10 PoolSize=10 DefaultLeaseTimeSec=12h MaxLeaseTimeSec=24h When trying to connect to the bluetooth PAN I get Oct 17 15:28:39 vasig-imx6ul-txul-emmc systemd-networkd[307]: Failed to determine timezone: Invalid argument Oct 17 15:28:39 vasig-imx6ul-txul-emmc systemd-networkd[307]: pan0: Could not start DHCPv4 server instance: Device or resource busy Oct 17 15:28:39 vasig-imx6ul-txul-emmc systemd-networkd[307]: pan0: Failed The message " pan0: Could not start DHCPv4 server instance: Device or resource busy" seems to suggest that only one server instance is allowed. Weirdly the device connecting did get an ip address. But if I look at the status of the pan0 I see: root@vasig-imx6ul-txul-emmc:~# networkctl status pan0 ● 4: pan0 Link File: /lib/systemd/network/99-default.link Network File: /etc/systemd/network/30-pan0-bridge.network Type: bridge State: routable (failed) Driver: bridge HW Address: 82:2f:45:2a:9c:5a Address: 192.168.10.1 eth0 is named such that it should be configured before the pan0.
