macchanger

macchanger 和 ifconfig [interface] hw ether [MAC] 的功能一樣, 可以變更網路卡卡號,
但並不是實體地修改卡號, 重開機後仍會回復, 嚴格說起來是可以設定網路卡卡號.
另外一個好用功能是可以查詢 vendor

查詢本機 eth0
# macchanger -s eth0
Current MAC: 00:02:b3:9b:b9:ba (Intel Corporation)

查詢 00:e0:4c 開頭是那一家做的
# macchanger -l | grep 00:e0:4c
7079 - 00:e0:4c - Realtek Semiconductor Corp.

列出 D-Link 的 MAC list
# macchanger --list=D-Link

指定 keyword 大小寫有差, 資料檔 /usr/local/share/macchanger/OUI.list 的內容, 大小寫並沒有統一,
還是用 macchanger -l | grep -i keyword 比較實用
