I've been running IPv6 on my notebook computer for years, using NetworkManager to configure the networking. The consistent IPv6 address had long been based on the MAC address, but now it's a random number. How did this happen and what do I do to go back to the MAC based address? As always, the temporary privacy addresses are random.
It changed with 15.0 (compared to 42.3). Simple solution -- switch to "wicked". If you want to continue using NetworkManager, then find the appropriate file for this connection in "/etc/NetworkManager/system-connections" Edit that file. Look for the section "[ipv6]". Look for the line addr-gen-mode= (I don't remember what comes after the "=", but I think it might be something like "StablePrivacy"). Change that line to: addr-gen-mode=eui64 After reboot, you should revert to address based of MAC. For the wired connection, there might not be a file. So edit that connection, and change the MTU to something smaller than 1500 (say, to 1480). That forces a file to be saved for that connection. Then you can edit that the same way. And you can edit the MTU back to 1500. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
