tell him this: srand(time) % 10000, you need the results of that mapped out into a rainbow table
for a timeframe
you used this
Code:
#include <stdlib.h>
#include <stdio.h>
#include <time.h>
int main(void)
{
int i;
time_t t;
srand((unsigned) time(&t));
for(i=0; i<10; i++)
printf("%d\n", rand() % 100);
return 0;
}
but you're thinking about it the wrong way
you will never be accurate enough trying it like that
You just want to output the results of srand()
Timestamp is just a really long number
and it's sequential
so, you can.... predict what... 12/2/2011 11:32:10 PM would be
exactly.
in a timestamp format
Now, if XXX game's RNG runs off the timestamp of the current time...
you can predict what it will generate
at 12/2/2011 11:32:10 PM
in the future.
So, a rainbow table just basically lists "all" the possible outcomes. I do 7 hours worth of times in my rainbow tables
Then I look for groups of time periods where linking % is high
because you just can't get accurate enough to know what exact server time is + the lag
So, you want to feed srand() with future times and map them out into a spreadsheet (excel or something)
Just small periods of time, then look at allllll the numbers under 22,000
because those are the ones that will link.
Or %%,000. whatever % it is
22,000 = 22%, etc.
and make a table with srand() outputs
then try to find a big group of low numbers
You want about... 2-3 seconds where 80% of the numbers are under your desired linking %. It's not hard to find if you have the output in front of you
Here are steps
1) pick day you want to link
2) find a 10-20 minute time period, predict their unix timestamps (just calculate, google it )
3) feed all those unix timestamps into srand() in order
4) save srand's output into CSV or some kind of output you can read
11:28pm
5) evaluate for 2-3 seconds of low numbers
^--- linking in a nutshell
