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@it.net.cn]# netstat -rn
Kernel IP routing table
Destination Gateway Genmask Flags MSS Window irtt Iface
184.82.152.96 0.0.0.0 255.255.255.248 U 0 0 0 eth0
169.254.0.0 0.0.0.0 255.255.0.0 U 0 0 0 eth0
0.0.0.0 184.82.152.97 0.0.0.0 UG 0 0 0 eth0
[root@it.net.cn]# cat /etc/sysconfig/network-scripts/ifcfg-eth0
# Intel Corporation 82567V-2 Gigabit Network Connection

NETMASK=255.255.255.248
IPADDR=184.82.152.98
GATEWAY=184.82.152.97

[root@it.net.cn]# ip route show
184.82.152.96/29 dev eth0 proto kernel scope link src 184.82.152.98
169.254.0.0/16 dev eth0 scope link
default via 184.82.152.97 dev eth0
[root@it.net.cn]# route -n
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
184.82.152.96 0.0.0.0 255.255.255.248 U 0 0 0 eth0

[root@it.net.cn]# ifconfig -a
