linux 某个网口不能ping同其他机器

#1

帖子 zhi5631 » 2013-12-06 9:36

Hi:
环境是这样的,一台机器每个网口设置一个ip地址,然后给其中一个再设置一个地址,结果最后设置的这个ip不能ping通同网段、同交换机的其他网卡。而该网卡的其他ip则可以ping通,请帮忙看看。

出问题的机器, 出问题的ip: 172.16.65.91:
该网卡绑定ip信息
eth1: <BROADCAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP qlen 1000
link/ether 90:e2:ba:1c:52:e9 brd ff:ff:ff:ff:ff:ff
inet 172.16.65.78/24 scope global eth1
inet 172.16.65.91/24 scope global secondary eth1
inet 172.16.65.80/24 scope global secondary eth1
inet6 fe80::92e2:baff:fe1c:52e9/64 scope link

发送free arp
[root@77 ~]# arping -c 1 -U -I eth1 -s 172.16.65.91 -b 172.16.65.91
ARPING 172.16.65.91 from 172.16.65.91 eth1

[root@77 ~]# arping -c 1 -U -I eth1 -s 172.16.65.91 -b 172.16.65.255
ARPING 172.16.65.255 from 172.16.65.91 eth1

route 信息:
[root@77 ~]# ip route

169.254.0.0/16 dev eth2 scope link metric 1004
default via 172.16.65.1 dev eth1 proto none

[root@77 ~]# ip route show table neteth1
172.16.65.0/24 dev eth1 proto kernel scope link
default via 172.16.65.1 dev eth1 proto none

客户端机器,
[root@81 ~]# ip n | grep 91
172.16.65.91 dev eth0 lladdr 90:e2:ba:1c:52:e9 STALE

与服务端的mac地址是一样的,
但是无法ping通:
[root@81 ~]# ping 172.16.65.91
PING 172.16.65.91 (172.16.65.91) 56(84) bytes of data.
^[^C
--- 172.16.65.91 ping statistics ---
2 packets transmitted, 0 received, 100% packet loss, time 1002ms

防火墙和selinux我确认是没有启动的,而且在服务段我ping出错ip172.16.65.91是可以ping通的,但ping不通其他的机器,结果如下,
[root@77 ~]# ping 172.16.65.91
PING 172.16.65.91 (172.16.65.91) 56(84) bytes of data.
