This is your MAC based address: 2601:c0:8105:82f0:325a:3aff:fe54:de1 It's created by taking the MAC address, inverting the 7th bit and inserting FFFE in the middle and prepending the prefix. BTW, you don't have to use sudo or be root to use ifconfig or ip to see what your addresses are. I just create a symlink so I don't have to type in the path to use the command as a mere mortal.

So now every hacker in the world knows my info and I have no idea if I have a firewall in place!
The link local address alone isn't a risk, but since you've posted your prefix, MAC and your MAC based address, then yes you told everyone. How do you not know if you have a firewall??? -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
