Hello,

Thank you very much for your reply.

1- I tried to make the server as you suggested in your link and after compiling and running the code on NIOS II IDE for eclipse the following messages are encountered:

panic: unlock NET

2- Do you have a method to test such a server code.

Your prompt response is highly appreciated.

I had this unlock NET error and found that my problem was that I was trying to open a UDP socket before I had run the following:

netmain();

TK_SLEEP(1);

--- Quote End ---

I moved my UDP socket code below those lines and the error went away.
