ifconfig已经过时

系统：Fedora 13;kernel:2.6.33.5-124
原来LINUX下配置网络经常用到“ifconfig”这个命令，好久没用，有些忘记了，就man了一下。仔细读读才知道，ifconfig好久之前就已经obsolete了。相关内容摘录如下：
#man ifconfig
NAME
ifconfig - configure a net work interface
NOTE
This program is obsolete! For replacement check ip addr and ip link. For statistics use ip -s link.
……
BUGS
       Ifconfig uses obsolete kernel interface.   It  uses  the  ioctl  access
       method  to  get  the  full  address  information, which limits hardware
       addresses to 8 bytes.  Since an Infiniband address is  20  bytes,  only
       the first 8 bytes of Infiniband address are displayed.

       While  appletalk DDP and IPX addresses will be displayed they cannot be
       altered by this command.
