vi /etc/sysconfig/network
加入：
GATEWAY=192.168.0.1
完整的如下：
NETWORKING=yes
HOSTNAME=localhost.localdomain
GATEWAY=192.168.0.1


1.ifconfig -a 和 cat /etc/resolv.conf  （主要查看ip/netmask和dns）
2.netstat -rn
3.cat /etc/sysconfig/network
4.cat /etc/sysconfig/network-scripts/ifcfg-eth0
5.traceroute 第一行就是自己的网关
6.ip route show
7.route -n

以上几个是比较常用的查询网关的命令。下面是范例：

[root@www.ctohome.com]# netstat -rn
