refuse.c

基于TCP-WRAP原理的系统监控的c语言实现代码

 /*
  * refuse() reports a refused connection, and takes the consequences: in
  * case of a datagram-oriented service, the unread datagram is taken from
  * the input queue (or inetd would see the same datagram again and again);
  * the program is terminated.
  *
