不要错过: 使用ifconfig VS IP:什么是它们之间的区别

[root@howtoing ~]# ifconfig eth0:0 172.16.25.127接下来,验证新创建的别名网络接口的地址,通过使用“ifconfig eth0命令:0”命令。
[root@howtoing ~]# ifconfig eth0:0 eth0:0 Link encap:Ethernet HWaddr 00:01:6C:99:14:68 inet addr:172.16.25.123 Bcast:172.16.25.63 Mask:255.255.255.240 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 Interrupt:17
[root@howtoing ~]# ifconfig eth0:0 down
[root@howtoing ~]# ifconfig eth0 hw ether AA:BB:CC:DD:EE:FF这些是在Linux中配置网络接口,以获取更多信息和ifconfig命令的用法使用像“ 人的ifconfig”的联机帮助页在终端的最有用的命令。查看以下一些其他网络实用程序。
