If you depend upon the package 'macchanger' to randomize your mac
address, be aware that its new version, 1.7, recently uploaded to
debian,contains a bug that the final three octets of an address are NOT
being randomized. For example, if you attempt 'macchanger -e' your mac
address will not change at all.
