Centos/Linux下如何查看网关地址/Gateway地址

Centos/Linux下如何查看网关地址/Gateway地址? 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.



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@localhost]# netstat -rn

[root@localhost]# cat /etc/sysconfig/network-scripts/ifcfg-eth0
