Socket stuff

[Stephen Inkpen]

When I run this the first time I can telnet into the port '5000' and connect. 
But after disconnecting I can't connect again afterwards....  Is there some
sort of timeout thing or something?

Here is my code:

----------------------------------------------------------
#include <string.h>
#include <sys/socket.h>
#include <sys/types.h>
#include <netinet/in.h>

#define PORT    5000

int main()
{
    struct sockaddr_in local_addr;
    struct sockaddr_in remote_addr;
    int file,remote_file,size,length;
    char *response = "hello";

    file = socket(AF_INET,SOCK_STREAM,0);
    if (file == -1)
        printf("No socket call work");

    local_addr.sin_family = AF_INET;
    local_addr.sin_port = htons(PORT);
    local_addr.sin_addr.s_addr = inet_addr("192.168.1.4");
    memset(&(local_addr.sin_zero),0,8);

    if (bind(file, (struct sockaddr *) &local_addr, sizeof(struct sockaddr)) == -1)
        printf("Bind no work");

    listen(file,5);
    size = sizeof(struct sockaddr_in);
    remote_file = accept(file, (struct sockaddr *) &remote_addr, &size);

    length = strlen(response);
    send(remote_file,response,length, 0);

    close(file);
    close(remote_file);
}
