Linux下查看网关的命令还是很多的,不过如果IP是DHCP获取,那么有些命令是不适用的,当然也有通用的查询网关命令.
配置网关:
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
