Hi;
Can anyone tell me how to configure kernel to support AF_INET.
Now i work with Monavista 2.6.10 on dm6446 evm.
When i run the server on the testboard
the server print
bind start
bind end
listen start
listen end
server waiting
accept start
When i run the client on the testboard,
the client print
connect start
the client can not connect on the server
But when i run the the same test code on the pc
the server print
bind start
bind end
listen start
listen end
server waiting
accept start
the client print
connect start
accept end
read start
connect end
write start
read end
write start
write end
server waiting
accept start
write end
read start
read end
char from server = B
The client can connect the server .
Here is the server code
#include<sys/types.h>
#include<sys/socket.h>
#include<stdio.h>
#include<sys/un.h>
#include<unistd.h>
#include<netinet/in.h>
#include<arpa/inet.h>
int main()
{
int server_sockfd, client_sockfd;
int server_len, client_len;
// struct sockaddr_un server_address;
// struct sockaddr_un client_address;
struct sockaddr_in server_address;
struct sockaddr_in client_address;
unlink("server_socket");
// server_sockfd = socket(AF_UNIX, SOCK_STREAM, 0);
server_sockfd = socket(AF_INET, SOCK_STREAM, 0);
// server_address.sun_family = AF_UNIX;
// strcpy(server_address.sun_path, "server_socket");
server_address.sin_family = AF_INET;
// server_address.sin_addr.s_addr = inet_addr("127.0.0.1");
// server_address.sin_port = 9734;
server_address.sin_addr.s_addr = htonl(INADDR_ANY);
server_address.sin_port = htons(9734);
server_len = sizeof(server_address);
printf("bind start\n");
bind(server_sockfd, (struct sockaddr *)&server_address, server_len);
printf("bind end\n");
printf("listen start\n");
listen(server_sockfd, 5);
printf("listen end\n");
while(1)
{
char ch;
printf("server waiting\n");
client_len = sizeof(client_address);
printf("accept start\n");
client_sockfd = accept(server_sockfd, (struct sockaddr *)&client_address, &client_len);
printf("accept end\n");
printf("read start\n");
read(client_sockfd, &ch, 1);
printf("read end\n");
ch++;
printf("write start\n");
write(client_sockfd, &ch, 1);
printf("write end\n");
close(client_sockfd);
}
}
Here is the client code
#include<sys/types.h>
#include<sys/socket.h>
#include<stdio.h>
#include<sys/un.h>
#include<unistd.h>
#include<netinet/in.h>
#include<arpa/inet.h>
int main()
{
int sockfd;
int len;
// struct sockaddr_un address;
struct sockaddr_in address;
int result;
char ch= 'A';
// sockfd = socket(AF_UNIX, SOCK_STREAM, 0);
sockfd = socket(AF_INET, SOCK_STREAM, 0);
// address.sun_family = AF_UNIX;
// strcpy(address.sun_path, "server_socket");
address.sin_family = AF_INET;
address.sin_addr.s_addr = inet_addr("127.0.0.1");
// address.sin_port = 9734;
address.sin_port = htons(9734);
len = sizeof(address);
printf("connect start\n");
result = connect(sockfd, (struct sockaddr *)&address, len);
printf("connect end\n");
if(result == -1)
{
perror("oops: client1");
exit(1);
}
printf("write start\n");
write(sockfd, &ch, 1);
printf("write end\n");
printf("read start\n");
read(sockfd, &ch, 1);
printf("read end\n");
printf("char from server = %c\n", ch);
close(sockfd);
exit(0);
}
Thanks. |
