connecting ARM board through internet

Check your router and DNS server:

# route # cat /etc/resolv.conf

and try to ping those.

Attach a PC to your network, and try to ping your PC. Install wireshark on PC, and see what's happening. Compare IP settings of PC with ARM board.

Note that public hosts on the internet don't always respond to ping. For instance, I can ping

but not cnn.com. First make sure you can ping the same host from a working PC.

hello

I changed the ip address , and mask of the mini board by getting them from the command eth0 in my computer:

inet addr:116.74.41.85 Bcast:116.74.47.255 Mask:255.255.248.0

I put this ip address in the arm board instead of 192.168.1.230

inet addr:116.74.41.85

and the mask I put this at the place of 255.255.255.0

Mask : 255.255.248.0

Than I got the DNS from this command in my PC :

cat /etc/resolv.conf

and got this result:

piyush@piyush-desktop:~$ cat /etc/resolv.conf # Generated by NetworkManager nameserver 202.88.216.4

I than changed the DNS in arm board from 192.168.1.1 to 202.88.216.4

than I changed the gateway from 192.168.1.1 to 116.74.40.1

and saved the above configuration in the /etc/eth0-settings file of my arm board

Now when I connect the ethernet cable to the board and run the command :

[root@FriendlyARM /]# ping 116.74.41.85 PING 116.74.41.85 (116.74.41.85): 56 data bytes 64 bytes from 116.74.41.85: seq=0 ttl=64 time=0.925 ms 64 bytes from 116.74.41.85: seq=1 ttl=64 time=0.452 ms 64 bytes from 116.74.41.85: seq=2 ttl=64 time=0.438 ms 64 bytes from 116.74.41.85: seq=3 ttl=64 time=0.455 ms

but when I ping 192.168.1.1

[root@FriendlyARM /]# ping 192.168.1.1 PING 192.168.1.1 (192.168.1.1): 56 data bytes

and nothing else

I run the command ping 192.168.1.1

result:

[root@FriendlyARM /]# ping 192.168.1.1 PING 192.168.1.1 (192.168.1.1): 56 data bytes

and nothing else than I stop it by ctrl+C

and than I ran the command route -n

result:

piyush@piyush-desktop:~$ route -n Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface

116.74.40.0 0.0.0.0 255.255.248.0 U 1 0 0 eth0 169.254.0.0 0.0.0.0 255.255.0.0 U 1000 0 0 eth0 0.0.0.0 116.74.40.1 0.0.0.0 UG 0 0 0 eth0

similarly when I got the pinging in my arm board from ping 116.74.41.85

I ran the command route -n on my arm board than I got this:

result:

[root@FriendlyARM /]# route -n Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface 116.74.40.0 0.0.0.0 255.255.248.0 U 0 0 0 eth0 0.0.0.0 116.74.40.1 0.0.0.0 UG 0 0 0 eth0 [root@FriendlyARM /]#

Also the result of only route on my PC is this :

result:

piyush@piyush-desktop:~$ route Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface

116.74.40.0 * 255.255.248.0 U 1 0 0 eth0 link-local * 255.255.0.0 U 1000 0 0 eth0 default 116.74.40.1 0.0.0.0 UG 0 0 0 eth0 piyush@piyush-desktop:~$

Now what is the problem. I have described all the steps which I have tried to connect the internet successfully to my arm board and I think

with your help I am able to ping the ip address successfully but not getting connection still.

So now what I should do to correct it.

Thank you
