将c unix服务器/套接字连接到java windows客户端/套接字

我在我的macbook中使用c创建了一个服务器套接字,并在运行windows xp的不同机器中使用Java创建了一个客户端/套接字.我已将端口指定为5000但我无法指定正确的主机,因此无法建立连接.当我使用WinSock2在Windows XP中创建一个c服务器/套接字时,连接完全正如我使用localhost …任何想法???

Thnx提前

C代码

int main(int argc,const char ** argv)
{

/* SOCKET VARIABLES */
int sock;
struct sockaddr_in server;
int mysock;
char buff[1024];
int rval;


/*CREATE SOCKET*/
sock =socket(AF_INET,SOCK_STREAM,0);
if (sock<0) 
{
    perror("*FAILED TO CREATE SOCKET*");
    exit(1);
}

server.sin_family=AF_INET;
server.sin_addr.s_addr=INADDR_ANY;
server.sin_port=5000;

/*CALL BIND*/
if (bind(sock,(struct sockaddr *)&server,sizeof(server)))
{
    perror("BIND FAILED");
    exit(1);
}


/*LISTEN*/
listen(sock,5);


/*ACCEPT*/
do{

    mysock= accept(sock,(struct sockaddr *) 0,0);

    if (mysock==-1) 
    {

        perror ("ACCEPT FAILED");
    }
    else
    {
        memset(buff,sizeof(buff));

        if ((rval=recv(mysock,buff,sizeof(buff),0)) <0) {
            perror("READING STREAM MESSAGE ERROR");
        }
        else if(rval==0)
            printf("Ending connection");
        else
            printf("MSG: %sn",buff);

        printf("GOT THE MESSAGE (rval = %d)n",rval);

    }

    return 0;
}while (1) ;
