The first command runs a TCP server that sends the current password as soon as a client connects. The second command is the client that receives the current password, and replies with the next.

$ ./suconnect 3000

Level Goal 24 → 25

A daemon is listening on port 30002 and will give you the password for bandit25 if given the password for bandit24 and a secret numeric 4-digit pincode. There is no way to retrieve the pincode except by going through all of the 10000 combinations, called brute-forcing.

You do not need to create new connections each time

Ciljni nivo

Daemon (DEMON) osluškuje port 30002 i dat će vam lozinku za `bandit25` ako dobijete lozinku za `bandit24` i tajni numerički 4-cifreni PIN kod. Ne postoji način da se povrati PIN kod osim prolaskom kroz svih 10000 kombinacija, što se naziva brute-forcing.

Ne morate svaki put kreirati nove veze.

AJMO @coja DI SMO ZAPELI?

KAKO DALJE? HH hack bandit xDD
