解决：

$ whereis ifconfig
ifconfig: /sbin/ifconfig.old /sbin/ifconfig /usr/share/man/man8/ifconfig.8.gz /usr/share/man/man8/ifconfig.8

$ /sbin/ifconfig

解决二：
查看登录用户的path：

$ echo $PATH

path中没有 /sbin/ifconfig ，添加到path中：
$ export PATH=$PATH:/sbin

再次执行：
$ ifconfig
eth1 Link encap:Ethernet HWaddr XXXXXXXXX
inet addr:XXXXXXXX Bcast:XXXXXXX Mask:255.255.255.128
