I am programming a simple TCP / IP server in Linux, but after running it in the terminal, I get no response, not even print a line that should print at the beginning of the program. When compiling gives no indication of errors and / or warnings. The code is:
#include <stdio.h>
#include <errno.h>
#include <sys/socket.h>
#include <resolv.h>
#include <arpa/inet.h>
#include <pthread.h>
#include <stdlib.h>
#include <strings.h>
#define ADRRESS "127.0.0.1"
#define PORT 9999
/*void receive_tcp(int clientfd)
{
char buffer1[7];
//char *buffer2;
int n, i;
n = read(clientfd, buffer1, sizeof(buffer1));
for(i=0;i<n;i++)
{
printf("%c", buffer1[i]);
}
}*/
void main()
{
int sock;
struct sockaddr_in s1;
char buffer1[7];
int n, i;
printf("A criar socket...");
if ((sock = socket(AF_INET, SOCK_STREAM, 0)) < 0)
{
printf("Erro ao criar socket.");
exit(1);
}
bzero(&s1, sizeof(s1));
s1.sin_family = AF_INET;
s1.sin_port = htons(PORT);
s1.sin_addr.s_addr = INADDR_ANY;
printf("A ligar ao socket...");
if (bind(sock, (struct sockaddr*)&s1, sizeof(s1)) != 0)
{
printf("Erro ao ligar socket.");
exit(1);
}
printf("A configurar socket...");
if (listen(sock, 10) != 0)
{
printf("Erro ao configurar socket.");
exit(1);
}
printf("A entrar no ciclo...");
while(1)
{
int clientfd;
struct sockaddr_in client_addr;
int addrlen=sizeof(client_addr);
pthread_t thread1;
printf("À espera de uma nova ligação...");
clientfd = accept(sock, (struct sockaddr*)&client_addr, &addrlen);
n = read(clientfd, buffer1, sizeof(buffer1));
for(i=0;i<n;i++)
{
printf("%c", buffer1[i]);
}
/*pthread_create(&thread1, 0, receive_tcp, clientfd);
pthread_detach(thread1);*/
}
}
