The MAC stays the same throughout each working day.The MAC should change regularly to prevent a network knowing that I’m the same person who walked past 75 times over the last year.This means Starbucks WiFi sees a different MAC from London Underground, preventing linking my identity across different providers. The MAC should be different across different networks.I wanted to randomize my MAC address, but with three particular caveats: MAC addresses don’t need to stay the sameįortunately, it’s possible to spoof your MAC address to a random one without fundamentally breaking networking. I don’t subscribe to being tracked and sold by mega-corps, so I spent a few hours hacking a solution.

Didn’t read the terms and conditions? You might assume that free airport WiFi is subsidised by flogging ‘customer analytics’ (your personal information) to hotels, restaurant chains and whomever else wants to know about you. If you’ve ever put your real name into one of those Craptive Portals on a WiFi network you’ve now tied your identity to that MAC address.

The snag with this design is that your unique, unchanging MAC address is just perfect for tracking you.

It’s how networking works: any time you connect to a WiFi network, the router uses that address to send and receive packets to your machine and distinguish it from other devices in the area. It’s possible to limit this tracking by using pseudo-random MAC addresses.Įvery network device like a WiFi or Ethernet card has a unique identifier called a MAC address, for example b4:b6:76:31:8c:ff. That data can be shared and sold, and often identifies you as an individual. Your device’s MAC address can be used to track you across the WiFi networks you connect to. This directive is used to assign a MAC address to an interface, overriding the one assigned to the physical NIC, This directive should not be used in conjunction with HWADDR.Paul Fawkesley Paul Fawkesley December 2017 Randomize your WiFi MAC address on Ubuntu 16.04 is the hardware address of the Ethernet device in the form AA:BB:CC:DD:EE:FF. This directive is useful for machines with multiple NICs to ensure that the interfaces are assigned to the correct device names regardless of the configured load order for each NIC's module, This directive should not be used in conjunction with MACADDR. Note: Red Hat does not support assigning a permanent MAC address to bond interfaces in active-backup mode with the fail_over_mac option set to follow or active.Īfter performing the necessary changes in the network configuration files make sure to reboot the system for the MAC address to take effect. # cat /etc/sysconfig/network-scripts/ifcfg-bond0īONDING_OPTS="mode=active-backup primary=eno1 miimon=100" # cat /etc/sysconfig/network-scripts/ifcfg-eno2 # cat /etc/sysconfig/network-scripts/ifcfg-eno1

The HWADDR directive is changed with MACADDR : # cat /etc/sysconfig/network-scripts/ifcfg-eth1Īssigning permanent MAC address for a bonding network interface. # cat /etc/sysconfig/network-scripts/ifcfg-eth1 If HWADDR= directive is present in the network configuration file then make sure to replace it with MACADDR= directive and its corresponding value as follows: So that this value will be taken as the permanent MAC address of the network interface.
