Hi All,
I have a little progress with the problem what i am facing.
I am testing UDP application.
Server IP 192.168.0.100 (Host PC)
Client IP 192.168.0.20 (Target PC)
I am running server on Linux PC and client on Target.
When i run the client Gratuitous ARP request is sent to query its own IP
address.
Then ARP is sent to know who has 192.168.0.100 Tell 192.168.0.20
Got a reply for ARP saying 192.168.0.100 is at 00:0c:76:11:0f:c2 (MAC
address of Linux PC )
Now UDP packets are not getting sent.
If I broadcast the packet I see UDP packets going out to 192.168.0.255 but
server is unable to receive.
What could be the problem ?.
Thanks in advance
Regards,
Madhava S

Hi Andrew,
I am running the server in the target. when i check in the ethereal two
ARP
packets are sent from the target and both of them are Gratuitous ARP. I
browsed in the net for Gratuitous ARP. In the following link
http://www.geocities.com/SiliconValley/Vista/8672/network/arp.html?20061#A28
He says host sends ARP request to resolve its own IP address.
He also says in a properly configured network there will not be reply for
gratuitous ARP request.
This is just the target making sure nobody else is using the same
address it has been allocated. No reply is good.
When I run client in Linux PC client sends six ARP packets and stops.
This is bad. The target should of replied to the ARPs. I assume the
ARPs are for the correct address?
I am using the same IP in the Redboot. I tried with different IP in
Redboot
also. I am getting the same output.
Redboot and the application must have different addresses. Try again
with different addresses.
Andrew
