【转】Linux下修改MAC地址三种方法

方法一：
1.关闭网卡设备

ifconfig eth0 down

2.修改MAC地址

ifconfig eth0 hw ether MAC地址

3.重启网卡

ifconfig eth0 up


方法二：
以上方法一修改后linux重启后MAC又恢复为原来的，为了下次启动时修改后的MAC仍有效，我们可以修改文件file:/etc/rc.d/rc.sysinit(RedFlag Linux为这个文件，其他版本的linux应该不同)的内容，在该文件末尾加以下内容：

ifconfig eth0 down
ifconfig eth0 hw ether MAC地址
ifconfig eth0 up


方法三：
很简单的，只是在./etc/sysconfig/network-scripts/ifcfg-eth0中加入下面一句话：

MACADDR=00:AA:BB:CC:DD:EE

【转】Ether Types

Ether Types (last updated 2008-09-09) NOTE: Please see [RFC5342] for current information and registration procedures. This registry will be revised soon and will be replaced with up-to-date information. Many of the networks of all classes are Ethernets (10Mb) or Experimental Ethernets (3Mb). These systems use a message "type" field in much the same way the ARPANET uses the "link" field. If you need an Ether Type, contact: IEEE Registration Authority IEEE Standards Department 445 Hoes Lane Piscataway, NJ 08854 Phone +1 732 562 3813 Fax: +1 732 562 1571 Email: <ieee-registration-authority& ieee.org > http://standards.ieee.org/regauth/index.html The following list of EtherTypes is contributed unverified information from various sources. Another list of EtherTypes is maintained by Michael A. Patton and is accessible at: <URL: http://www.cavebear.com/CaveBear/Ethernet/ > <URL: ftp://ftp.cavebear.com/pub/Ethernet-codes > Assign...
