Script korigieren

Hallo könnt ihr mir folgenden Quellcode korrigieren sodass ich mit diesem per LAN ins Internet gehen kann,und dann bitte hier ins Forum den korrigiertern Quellcode schreiben?
Das währe sehr nett
Quellcode:
#include <stdio.h>
#include <sys/types.h>
#include <sys/socket.h>
#include <netinet/in.h>
#include <netdb.h>

void error(char *msg)
{
perror(msg);
exit(0);
}

int main(int argc, char **argv)
{
int sockfd, portno, n;
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);
printf(Please enter the message: );
bzero(buffer,256);
fgets(buffer,255,stdin);
n = write(sockfd,buffer,strlen(buffer));
if (n < 0)
error(ERROR writing to socket);
bzero(buffer,256);
n = read(sockfd,buffer,255);
if (n < 0)
error(ERROR reading from socket);
printf(%s\n,buffer);
return 0;
}

Was für ne Fehlermeldung kommt denn?

Gruß
