this code is a game that uses socket to be able to connect to each other so that there would be a 2player game.. but there something wrong here...here's the code..i'm using linux as my operating system ..this is the client side..

exit(0);
}
int main(int argc, char *argv[])
{
int sockfd,portno, n, n1;
struct sockaddr_in serv_addr;
struct hostent *server;
char buffer[256];
if (argc < 3) {
fprintf(stderr,"usage %s hostname port\n", argv[0]);
exit(0);
}
portno = atoi(argv[2]);
sockfd = socket(AF_INET, SOCK_STREAM, 0);
if (sockfd < 0)
error("ERROR opening socket");
server = gethostbyname(argv[1]);
if (server == NULL) {
fprintf(stderr,"ERROR, no such host\n");
exit(0);
}
bzero((char *) &serv_addr, sizeof(serv_addr));
serv_addr.sin_family = AF_INET;
bcopy((char *)server->h_addr,
(char *)&serv_addr.sin_addr.s_addr,
server->h_length);
serv_addr.sin_port = htons(portno);
//if (connect(sockfd,&serv_addr,sizeof(serv_addr)) < 0)
// error("ERROR connecting");
//if (connect(sockfd, &serv_addr,sizeof(serv_addr)) < 0)
//error("ERROR connecting");
printf("Welcome to Battle of Jack 'en Poy\n");
printf("Please enter your name: ");
bzero(buffer,256);
fgets(buffer,255,stdin);
n = write(sockfd,buffer,strlen(buffer));
bzero(buffer,256);
n = write(sockfd," ! ",3);

bzero(buffer,256);
n = read(sockfd,buffer,255);
if (n < 0)
error("ERROR reading from socket");
printf("%s\n",buffer);
return 0;
}this is the server side..
