How do I prevent this MAC address generation and tell networkd to just use one from the slaves? Files The IP address of this Linux server is 192.168.0.1 which is labeled as inet. Focus on the area which is highlighted in red colour. Check IP address and Gateway Mask ifconfig You will see output of this command like below screenshot. For other kind of netdevs, if this option is not set, then MAC address is generated based on the interface name and the machine-id(5). Launch PuTTY and connect to Linux server. If this option is not set, "vlan" devices inherit the MAC address of the physical interface. ![]() Please specify it in "" section of the corresponding work(5) file. For "tun" or "tap" devices, setting MACAddress= in the "" section is not supported. This breaks DHCP, and doesn't follow the expectation set by the Linux kernel bonding documentation that states that the bond interface will take the MAC address of one of its slaves.Īccording to the networkd documentation, the issue appears to be this: Steps needed to change mac address: The first step is to Open your terminal, and enter. macchanger is a utility that is available in almost all Linux distributions so its availability does not represent any problem. ![]() When I add the config files below into /etc/systemd/network and restart systemd-networkd, I find that the MAC addresses of bond0, eth0 and eth2 have all been changed to a single, locally administered address. ![]()
