You can find the Mac address even the cable is not plugged.

Or, go to the “Network” in the left pane and click on the “gear” button for the wired network. If Wi-Fi connected, in the first tab click on the “gear” icon after the connected network will open the information page.

Find MAC Address in Ubuntu or Other Linux with GNOME Desktop:įor the Linux with GNOME Desktop, e.g., Ubuntu 18.04 +, Debian 11, Fedora Workstation, and CentOS 8, it’s easy to find it.įirstly, go to upper-right corner system tray menu and click the option to open “Settings”. While a notebook will have two: one for wireless card and another for the wired. Usually, desktop PC has only one MAC address for the wired network. Each network device has its own hardware address. MAC Address, stands for media access control address, is a unique identifier assigned to a network interface controller for use as a network address in communications. Here are how to find it either in graphical way or by running command. (On a physical system or a full VM, it would also be possible to rename eth0 to something else, then create a virtual eth0 in its place, but this might not work with WSL2 due to the way it's architectured.Sometimes you need to know the physical hardware address (aka MAC Address) of your network cards on Ubuntu or Debian Linux. 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.
