How to know a network issue
Now I know my device is working perfectly and the problem is with network. How would I make sure its the problem with the network but not with my device.
Can anyone guide to make some solution.
You could use tcpdump on the sender to trace, what really is sent and returns.
Also, if that device is unix based, then running tcpdump there also makes sense.
Did you check for errors with dmesg and ifconfig?
Are the connection parameters ok? 100mbit/s fullduplex or 1gbit/s fullduplex. Check with mii-tool or dmesg.
I also wouldnt rule out that device (btw: what is it?):
Maybe it has some low timeouts, that cant be met by your (busy?) network.
Or something simple like wrong gateway, netmask or dns?You must always face the curtain with a bow.
How do you know that the device works perfectly if it doesn't respond?
