Hi, That is a known (but tricky) bug reported some times ago. David Baroso proposed something like : sum += ((*(u_int8_t *)addr & 0xFF)<<8); The difficulty is to find something working on both big and little endian systems.
Hello, I tested that the code above in both sparc and x86 and it worked like a charm. Perhaps it could be the best solution :-?
