linux 下socket编程，可以互相链接但是无法发送数据，请各位大侠帮忙看看

本文导语: 只是想实现简单的俩台电脑通信：服务器端： #include #include #include #include #include #include #include #include #define SERVPORT 3333 #define MAXDATASIZE 100 #define SERVER_IP "127.0.0.1" #define DATA "this is a client message" int ...

只是想实现简单的俩台电脑通信：
服务器端：
#include
#include
#include
#include
#include
#include
#include
#include
#define SERVPORT 3333
#define MAXDATASIZE 100
#define SERVER_IP "127.0.0.1"
#define DATA  "this is a client message"
int main(int argc, char* argv[]) {
    int sockfd, recvbytes;
    char buf[MAXDATASIZE];
    struct hostent *host;
    struct sockaddr_in serv_addr;
    if (( sockfd = socket(AF_INET, SOCK_STREAM, 0)) == -1) {
        perror("socket error!");
        exit(1);
    }
    bzero(&serv_addr,sizeof(serv_addr));
    serv_addr.sin_family    = AF_INET;
    serv_addr.sin_port      = htons(SERVPORT);
    serv_addr.sin_addr.s_addr= inet_addr(SERVER_IP);

    if (connect(sockfd, (struct sockaddr *)&serv_addr,sizeof(struct sockaddr)) == -1) {
        perror("connect error!");
        exit(1);
    }

    write(sockfd,DATA, sizeof(DATA));
   if ((recvbytes = recv(sockfd, buf, MAXDATASIZE,0)) == -1) {
        perror("recv error!");
        exit(1);
    }
    buf[recvbytes] = '';
    printf("Received: %s",buf);
    close(sockfd);
    return 0;
}

客户端没有问题吧：
#include
#include
#include
#include
#include
#include

int main(int argc, char *argv[])

{

int server_sockfd;
int client_sockfd;
int len;

struct sockaddr_in my_addr;
struct sockaddr_in remote_addr;
int sin_size;

char buf[BUFSIZ];
memset(&my_addr,0,sizeof(my_addr));
my_addr.sin_family=AF_INET;
my_addr.sin_addr.s_addr=INADDR_ANY;
my_addr.sin_port=htons(8000);

if((server_sockfd=socket(PF_INET,SOCK_STREAM,0))
