spoof - Easily spoof your MAC address in OS X & Linux!

•    Javascript

---

Node.js port of the popular SpoofMAC Python utility (GitHub: feross/SpoofMAC).I made this because changing your MAC address in OS X is harder than it should be. The Wi-Fi card needs to be manually disassociated from any connected networks in order for the change to apply correctly – super annoying! Doing this manually each time is tedious and lame.

It is streams2 and operates purely using streams which means you can easily extract/parse tarballs without ever hitting the file system.Note that you still need to gunzip your data if you have a .tar.gz.
