我用uuid模块取Mac地址的，刚开始很完美，可是后来发现同一台主机取来的Mac地址经常变化，很不靠谱啊，有时候取到的根本不是本机的Mac,也不知道为什么会这样。
求助怎么用Python取一台主机的Mac并且不会自己乱变，另外我的代码贴上来：
def getMac():
mac=uuid.UUID(int = uuid.getnode()).hex[-12:]
return ":".join([mac[e:e+2] for e in range(0,11,2)])
 | 你装了虚拟机就这样了 |
 | 3 s51431980 Jan 17, 2015 If you look at the getnode documentation it says that it will return a random long if it fails to detect the mac: "If all attempts to obtain the hardware address fail, we choose a random 48-bit number with its eighth bit set to 1 as recommended in RFC 4122." |
