一台电脑CentOS6.4, 上面3个物理网口, 其中两个进行直连了,
eth4 Link encap:Ethernet HWaddr 00:1B:21:36:60:0E
inet addr:192.168.101.10 Bcast:192.168.101.255 Mask:255.255.255.0
inet6 addr: fe80::21b:21ff:fe36:600e/64 Scope:Link
UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1
RX packets:17 errors:0 dropped:0 overruns:0 frame:0
TX packets:261 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:1000
RX bytes:1476 (1.4 KiB) TX bytes:11274 (11.0 KiB)
Memory:dd420000-dd440000
eth5 Link encap:Ethernet HWaddr 00:1B:21:36:60:0F
inet addr:192.168.101.175 Bcast:192.168.101.255 Mask:255.255.255.0
inet6 addr: fe80::21b:21ff:fe36:600f/64 Scope:Link

RX bytes:15120 (14.7 KiB) TX bytes:2034 (1.9 KiB)
Memory:dd400000-dd420000
然后我把lo 回环地址给down 掉了. 想让包从外面走:
执行命令
#ping 192.168.101.10 -I 192.168.101.175
结果Ping 不通, 而且在Ping 的时候, 在eth4 和eth5 上面都抓不到任何包.
请高人指点!! |
