如何该网卡地址??
我想改改网卡的地址,请问怎么改啊??
如果我改后服务器还知道我改过或是还有什么办法认得我的机吗?
谢了

如改ip地址用
ifconfig eth0 xxx.xxx.xxx.xxx netmask xxx.xxx.xxx.xxx boardcast xxx.xxx.xxx.xxx
如改mac地址用
ifconfig eth0 hw ether xx:xx:xx:xx:xx:xx

ifconfig eth0 hw ether 后面这些我要改什么就什么吗?
还是16进制的???改后服务器知道你改的吗???

是16进制的例如：
ifconfig eth0 he ether 00:10:60:73:CF:C2
一般不会有什么影响，除非有些服务是跟mac地址绑定的，如有些防火墙

可以改成ff.ff.ff.ff.ff.ff吗??
或是00.00.00.00.00.00吗???改这个地址有什么限制吗???
改后可以立即生效还是要重新开机????跟ip有什么关系吗??

不能改成全ff或全00，好象这48位分为几段，每段用途都有定义，我在winXP下也做了实验，改为全ff后，网就不通了。
改后无须重启，立即生效。

[root@Snoopy root]# ifconfig eth0 he ether 88:88:88:88:88:88
he: Unknown host
ifconfig: `--help' gives usage information.
[root@Snoopy root]# ifconfig eth0 hw ether 88:88:88:88:88:88
SIOCSIFHWADDR: Device or resource busy
[root@Snoopy root]#
你说的he,ether各表示什么???

对不起，敲错了，应该先用
ifconfig eth0 down
然后
ifconfig eth0 hw ether
完了后，用ifconfig eth0 up 就行了
hw:hardware
ether:ethernet
由 Snoopy 在 03-12-2003 13:09 发表:
ifconfig eth0 down是不是先把网卡关了?
然后ifconfig eth0 hw ether 88:88:88:88:88:88
启动网卡,ifconfig eth0 up是不是???
那你最后两行说的是什么???谢了~

在/etc/rc.d/init.d/network加入
ifconfig eth0 hw ether xx:xx:xx:xx:xx:xx
重启就不会变了。
改ip地址则是在
/etc/sysconfig/network-scripts/ifcfg-eth0文件中
