修改网关为静态IP

http://hi.baidu.com/zuiini/blog/item/2c7027faaa90ec8f9e5146bf.html
route -v

<span class="ident">sudo</span> <span class="punct">/</span><span class="ident">etc</span><span class="punct">/</span><span class="ident">init</span><span class="punct">.</span><span class="ident">d</span><span class="punct">/</span><span class="ident">networking</span> <span class="ident">restart</span>

linux下查看网卡地址和网关

1、查看网卡地址的命令：ifconfig

2、查看dns的命令：route -n (destination Genmask都是0.0.0.0的那个)

UBUNTU没有sysconfig目录，设置静态IP在/etc/network/interfaces里面~
在GOOGLE找到的~

<span class="punct">$sudo vi /</span><span class="regex">etc</span><span class="punct">/</span><span class="ident">network</span><span class="punct">/</span><span class="ident">interfaces</span>

and adjust it to your needs (in this example setup I will use the IP address 192.168.0.100):
