So the file (as present in the rpi image we provided) is looking like this : #macaddr=00:90:4c:c5:12:38 That can probably explain what you're seeing ? -- Fabian Arrotin The CentOS Project | https://www.centos.org gpg key: 56BEC54E | twitter: @arrfab -------------- next part -------------- A non-text attachment was scrubbed...
