While connecting to the server , we got a different name every time
we wrote a bash 3 line script to get all the names to a file

#!/bin/bash
        for i in `seq 1 100`;
        do
                nc quizz.teaser.insomnihack.ch 1031 | grep year | cut -d ' ' -f8- | sed 's/.$//'
        done

after we got all the names , we sorted and deleted uniq.

we got all the names , we searched google for all years.(Using Xgoogle python)
and wrote a simple python script that answer to the server and get us the flag.
