18.22. 建​​​​​​​立​​​​​​​用​​​​​​​來​​​​​​​產​​​​​​​生​​​​​​​ MAC 位​​​​​​​置​​​​​​​的​​​​​​​ Script

Red Hat 虛​​​​​​​擬​​​​​​​化​​​​​​​可​​​​​​​以​​​​​​​為​​​​​​​每​​​​​​​個​​​​​​​虛​​​​​​​擬​​​​​​​主​​​​​​​機​​​​​​​在​​​​​​​建​​​​​​​立​​​​​​​時​​​​​​​製​​​​​​​造​​​​​​​一​​​​​​​組​​​​​​​ MAC 位​​​​​​​置​​​​​​​。​​​​​​​由​​​​​​​於​​​​​​​在​​​​​​​一​​​​​​​個​​​​​​​子​​​​​​​網​​​​​​​路​​​​​​​能​​​​​​​夠​​​​​​​製​​​​​​​造​​​​​​​無​​​​​​​數​​​​​​​個​​​​​​​ MAC 位​​​​​​​置​​​​​​​，因​​​​​​​此​​​​​​​不​​​​​​​會​​​​​​​造​​​​​​​成​​​​​​​重​​​​​​​複​​​​​​​。​​​​​​​您​​​​​​​可​​​​​​​以​​​​​​​寫​​​​​​​一​​​​​​​個​​​​​​​ script 來​​​​​​​製​​​​​​​造​​​​​​​ MAC 位​​​​​​​置​​​​​​​。​​​​​​​這​​​​​​​個​​​​​​​範​​​​​​​例​​​​​​​ sript 包​​​​​​​含​​​​​​​了​​​​​​​製​​​​​​​造​​​​​​​ MAC 位​​​​​​​置​​​​​​​的​​​​​​​參​​​​​​​數​​​​​​​：

#! /usr/bin/python
# macgen.py script generates a MAC address for Xen guests
#
import random
mac = [ 0x00, 0x16, 0x3e,
random.randint(0x00, 0x7f),
random.randint(0x00, 0xff),
random.randint(0x00, 0xff) ]
print ':'.join(map(lambda x: "%02x" % x, mac))

Generates e.g.:
00:16:3e:66:f5:77
to stdout
