Socket lukker ikke forbindelse

Har foelgende kode:

#define PORT 8088 // the port client will be connecting to
#define MAXDATASIZE 100 // max number of bytes we can get at once

void x10send(char *hostname)
{
  int len,sd,status,tmp,n,ix,noblock,postlen;
  int done = 0;
  char *message = (char *)malloc(8),ownhost[100],resp[30];
  struct sockaddr local,remote;
  struct hostent *hostinfo;

  noblock=1;

  sd=socket(AF_INET,SOCK_STREAM,0);
  if(sd<0) {
      printf("Error creating socket: %s\n",strerror(errno));
      goto slut;
  }

  local.sa_family=AF_INET;
  memset(local.sa_data,0,sizeof(local.sa_data));
  status=bind(sd,&local,sizeof(local));
  if(status<0) {
      printf("Error binding socket: %s\n",strerror(errno));
      goto slut;
  }

  hostinfo=gethostbyname(hostname);

  if(!hostinfo) {
      printf("Error looking up host: %s\n",hostname);
      goto slut;
  }

  remote.sa_family=hostinfo->h_addrtype;
  memcpy(remote.sa_data+2,hostinfo->h_addr_list[0],hostinfo->h_length);
  *((short *)remote.sa_data)=PORT;
  tmp=remote.sa_data[0];
  remote.sa_data[0]=remote.sa_data[1];
  remote.sa_data[1]=tmp;
  status=connect(sd,&remote,sizeof(remote));

  if(status!=0) {
      printf("Error connecting to host: %s port: %d\n",hostname,PORT);
      goto slut;
  }



      sleep(1);
          // read response

printf("Sending message\n");
      postlen=8;

  gethostname(ownhost,sizeof(ownhost));
      sprintf(message,"%c%c%c009LM",0x21,0x21,0x21);
          status=send(sd,message,8,0);

          //          sleep(1);

          // read response

          ix=0;
          while ((len=recv(sd,resp+ix,sizeof(resp)-ix-1,0))>0) {

        ix = ix + len;
          }
          resp[ix]='\0';
          printf("%s\n",resp);

             
slut:
free(message);
  close(sd);
  return;
}

int main(int argc, char *argv[])
{

        if (argc != 2)
    {
            fprintf(stderr,"usage: client hostname\n");
            exit(1);
        }


    x10send(argv[1]);
    printf("Done !\n");
        return 0;
}

Problemet er at close(sd); ikke lukker forbindelsen paa serveren.

Forslag ?
