求教 双网卡 问题 【在线等。。。】
系统:RedHat AS3
Kernel:2.4.21-20.ELsmp
网卡 ETH0 配置:
DEVICE=eth0
BOOTPROTO=none
BROADCAST=192.168.100.255
HWADDR=00:14:5E:2A:39:46
IPADDR=192.168.100.9
NETMASK=255.255.255.0
NETWORK=192.168.100.0
ONBOOT=yes
TYPE=Ethernet
USERCTL=no
PEERDNS=yes
TYPE=Ethernet
GATEWAY=192.168.100.1
网卡 ETH1 配置:
DEVICE=eth1
BOOTPROTO=none
HWADDR=00:14:5e:2a:39:47
IPADDR=192.168.50.12
NETMASK=255.255.255.0
NETWORK=192.168.50.0
BROADCAST=192.168.50.255
ONBOOT=yes
TYPE=Ethernet
USERCTL=no
PEERDNS=yes
TYPE=Ethernet
GATEWAY=192.168.50.1
route 如下:
Destination Gateway Genmask Flags Metric Ref Use Iface
192.168.100.0 * 255.255.255.0 U 0 0 0 eth0
192.168.50.0 * 255.255.255.0 U 0 0 0 eth1
169.254.0.0 * 255.255.0.0 U 0 0 0 eth1
default 192.168.100.1 0.0.0.0 UG 0 0 0 eth0
现在发现ping不到192.168.50.0网段上的主机,网卡ETH1上的流量是0,
命令tracepath输出如下:
[root@MCC root]# tracepath 192.168.50.1
1: 192.168.50.12 (192.168.50.12) 0.200ms pmtu 1500
1: 192.168.50.12 (192.168.50.12) 2991.477ms !H
Resume: pmtu 1500
命令ifconfig -a 输出如下:
[root@MCC root]# ifconfig -a

问题:双网卡感觉是只有一个启用了,另一个没有使用,哪位大侠遇到过这种问题,请指教。
谢谢~~~
