hello,

     I've got a bf518f-ezbrd, and I use the linux-kernel wih 2011R1. There is a problem confused me for a few days

which is I can "ping" iteself but it cannot be pinged from other compter. For example, the ip address of bf518f-ezbrd is 192.168.1.13, and i can use ping command ,just like "ping 192.168.1.13" , the response is

root:/> ping 192.168.1.13

PING 192.168.1.13 (192.168.1.13): 56 data bytes

64 bytes from 192.168.1.13: seq=0 ttl=64 time=0.000 ms

64 bytes from 192.168.1.13: seq=1 ttl=64 time=0.000 ms

64 bytes from 192.168.1.13: seq=2 ttl=64 time=0.000 ms

64 bytes from 192.168.1.13: seq=3 ttl=64 time=0.000 ms

64 bytes from 192.168.1.13: seq=4 ttl=64 time=0.000 ms

64 bytes from 192.168.1.13: seq=5 ttl=64 time=0.000 ms

64 bytes from 192.168.1.13: seq=6 ttl=64 time=0.000 ms

 

but use ping cmd , just like "ping 192.168.1.15", "192.168.1.15" is the ip address of my computer, the response is

 

root:/> ping 192.168.1.15

PING 192.168.1.15 (192.168.1.15): 56 data bytes

^C

run "ifconfig" cmd, the response is

The linux-kernel is default. What should I do to solve the problem?
