小弟刚学Linux,为了起步简单，用的是MagicLinux,网络设置中有static host一项，IP为127.0.0.1，将其换成我的固定IP来上网没有问题，但是每次开机都得重新设置，有什么方法可以一次奏效么？

楼主的网卡设备号是多少？
以我的机器为例，OS是SLES9SP2,2.6.5-7.191-default
楼主运行所有的命令，就可以设置好自己的固定IP了：

使用编辑工具，修改IPADDR='192.168.1.3'为你得IP，保存即可。

在/root/other/etc/sysconfig/network-scripts/ifcfg-eth0里面设置静态IP，然后用ifup eth0来上网

右键,打开终端,netconfig 对着输入内容,最后确定退出.ifdown eth0--->ifup eth0

楼主重启几次，查查网卡配置文件的修改日期，看看是不是每次都是重启的时间；--是否具有系统还原功能；

大家说的很详细了
