I may have found the error, in  target_to_host_sockaddr() we only have
sa_family = tswap16(target_saddr->sa_family); w.r.t endian.
However a AF_INET also have:
    stSockAddr.sin_port = htons(1100);
    stSockAddr.sin_addr.s_addr = htonl(INADDR_ANY);
There is no endian conversion for these(there may be other cases too?)
