netcat -C ip port same as netcat -L -p port
 
how to update:
 
-   while ((x = getopt (argc, argv, "ade:g:G:hi:lLno:p:rs:tuvw:z")) != EOF) {
+   while ((x = getopt (argc, argv, "aCde:g:G:hi:lLno:p:rs:tuvw:z")) != EOF) {
 
#ifdef WIN32
    WSACleanup();
#endif
 
      if (cycle == 1)
        goto recycle;
 
changed to：
 
      if (cycle == 1)
        goto recycle;
 
#ifdef WIN32
    WSACleanup();
#endif
