![]() ![]() I haven't tested this with Vivado specifically, but it works with other vendors that use FlexNet's generic lmgrd. ![]() So if you need an interface whose MAC address will never change, create a virtual one that looks like Ethernet (Linux offers several types, either a 'dummy' interface or a 'bridge' with no members would work equally well) with one of the listed names: ip link add vmnic0 type dummy ![]() (Also, at least some versions of FlexNet will look for xp0 as the very first option and use it exclusively if found, unlike the other interfaces which are combined into a list, as can be seen from the lmhostid tool.) Any one of the found MAC addresses can be used as the "Ethernet hostid" for licensing. By default, Hyper-V virtual switches (that are also used for WSL2) are set to prevent "MAC address spoofing" by the guest VMs, and will only forward frames with the MAC address that was originally assigned in the VM's configuration.īut the FlexNet licensing software is likely to look for other interface names – it seems that in addition to eth0, it will also gather MAC addresses from wlan0, bond0.9, and vmnic0.9. ![]()
