centos查看网关地址
Centos/Linux下如何查看網關地址/Gateway地址? Linux下查看網關的命令還是很多的,不過如果IP是DHCP獲取,那么有些命令是不適用的,當然也有通用的查詢網關命令.
?
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 第一行就是自己的網關
6.ip route show
7.route -n
以上幾個是比較常用的查詢網關的命令。下面是范例:
?
[root@www.ctohome.com]# netstat -rn

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

0.0.0.0???????? 184.82.152.97?? 0.0.0.0???????? UG??????? 0 0????????? 0 eth0
?
[root@www.ctohome.com]# cat /etc/sysconfig/network-scripts/ifcfg-eth0
