multimac实践

1、multimac简介

Multimac is a very simple Linux software that is able to emulate and use multiple virtual interfaces (with different MAC addresses) on a LAN using a single network adapter. The aim of the application is giving network developers a tool to emulate presence of multiple machines (with different MAC addresses) using a single network adapter.
Remember, in fact, that eth aliasing doesn’t allow to specify a different MAC address for aliases (e.g. if you setup an alias eth0:0 for eth0 you can’t provide a different MAC address to eth0:0). This application helps to hack this (the project originally was born as a test on Linux Tun/Tap driver).

2、multimac环境要求Requirements

• Linux 2.6 kernel (should work with 2.4 kernels too but i’ve never tested it)
• Linux Tun driver (run “modprobe tun” first)
• Linux bridging driver (run “modprobe brid
