Гхм! Действительно по netstat открыто, но как?
#include <stdio.h>
#include <sys/types.h>
#include <sys/socket.h>
#include <netinet/in.h>
#include "tst.h"
int ConnectionProccessing(int sd)
{
char buffer[ BUFFER_SIZE ];
int count;
memset(buffer,0,sizeof(buffer));
count= recv(sd, buffer,sizeof(buffer), 0);
if (count < 0)
{perror("Recive error, stop proccessing"); return 1;};
if (count >= BUFFER_SIZE)
{perror("Buffer overflow error"); return 2;};
if (buffer[0]=='0')
{perror("Conection terminated by remote side..."); return -1;};
buffer[count+1]=0;
printf("Recive \n %s \n", buffer);
return 0;
}
int main (int argc, char *argv[] )
{
int sd, exit_flag, port=DEFAULT_PORT;
struct sockaddr_in addr;
printf ("\n %s test control started sucsesfully \n", argv[0]);
if((sd = socket(PF_INET,SOCK_STREAM,0))==-1)
panic("Error socket creation,exit");
memset(&addr,0, sizeof(addr));
addr.sin_family = PF_INET;
addr.sin_port = htons(port);
addr.sin_addr.s_addr = INADDR_ANY;
if( bind(sd, &addr, sizeof(addr) )!=0 )
panic("Error on binding, exit");
if ( listen(sd, MAX_LISTEN) !=0 )
panic("Error on listening,exit");
exit_flag=0;
while( exit_flag == 0 )
{
int client, len=sizeof(addr);
client = accept(sd, &addr,&len);
printf ("\nHost ( %s : %d
)",inet_ntoa(addr.sin_addr),ntohs(addr.sin_port));
exit_flag=ConnectionProccessing(client);
close(client); /*Здесь закрыл*/
printf ("\nClient closed\n");
}
close(sd); /* И здесь тоже закрыл, факт?*/
printf ("\n%s finished\n", argv[0]);
return 0;
}
От вет на посылку '0' в качстве первого символа, то есть завершаем программку
[iscander@iscander gatedeamon]$ ./gatectrl
./test test control started sucsesfully
Conection terminated by remote side...: Success
Host ( 127.0.0.1 : 34431 )Client closed /*Здесь закрыл*/
./test test finished /* И здесь тоже закрыл, факт?*/
[iscander@iscander gatedeamon]$ ./test
./test test control started sucsesfully
Error on binding, exit: Address already in use
Ну понятно что при этом он висит открытым
