Menjebol server melalui Service FTP

Menjebol server melalui FTP dengan menggunakan scanner cukup mudah. Pertama yang perlu disiapkan adalah scanner, saya menyertakannya sourcenya dalam C. Berikut adalah code yang hanya perlu anda compile dengan gcc -o.

struct hostent *rh;
struct servent *rp;

int sock,i;
int str_ptr, stp_ptr;
int Usage(char *ARG);
int CONNECTION(int port);

int main(int argc, char *argv[])
{
if (argc != 4)
Usage(argv[0]);

str_ptr = atoi(argv[2]);
stp_ptr = atoi(argv[3]);
if (strcmp(argv[2],"-")==0 &&
strcmp(argv[3],"-")==0){
str_ptr = DEF_STR_PORT;
stp_ptr = DEF_STP_PORT;
}
if ( str_ptr > stp_ptr){
fprintf(stderr,"DetecT ErroR !!! On PortS,

Than .-\n");
Usage(argv[0]);
exit(OXO);
}

if ((rh=gethostbyname(argv[1])) == NULL){
fprintf(stderr,"Can't Resolve Host %s
.-\n",argv[1]);
Usage(argv[0]);
exit(OXO);
}

printf("ScanninG Host %s From %d TcP Port To %d
.-\n",argv[1],str_ptr,stp_ptr);
for (i=str_ptr; i <= stp_ptr; i++)
{
if (CONNECTION(i)==0)
{
rp=getservbyport(htons(i),"tcp");
printf("Port %d Is Open !!!
