Checksystem:

https://github.com/pomo-mondreganto/ForcAD

What tokens are for:

After you've connected to the flag submission system, you must type your team token in the first line, followed by flags (one per line).

Simple script for flag submission:
https://gist.github.com/pomo-mondreganto/a864e3a259045846dee1fa0cb9fa68ea
Protocol for checksystem (for Destructive Farm):
https://github.com/DestructiveVoice/DestructiveFarm/blob/master/server/protocols/forcad_tcp.py


Teams ips: 10.80.[0-N].2 (N is the number of teams).
There also will be an NPC team (with ip 10.80.0.2 )
Flag regex: [A-Z0-9]{31}=
Scoreboard will be available on http://10.10.10.10 inside the wireguard network and on http://cbsctf.live in global network.
Flags are accepted at 10.10.10.10:31337 (tcp service)

Actual formula of service points change can be found here:

https://github.com/pomo-mondreganto/ForcAD/blob/master/backend/scripts/create_functions.sql#L41

Service statuses:

- OK: service works perfectly
- DOWN: service is inaccessible
- CORRUPT: checker can't get one of the old flags
- CHECK FAILED: organizers mistake, oops
- MUMBLE: everything else

IMPORTANT
There will also be checksystem api route to help you during the game. It will be accessible on http://10.10.10.10/api/attack_data during the game and will contains JSON data of the following format:

{
"task_name": {
"ip1": ["hint1", "hint2", ...],
"ip2": ["hint1", "hint2", ...]
}
}


Hints are useful for situations when there are a lot of traffic on services and you can't find users with flags.
So hints will be ids, usernames, etc of users with alive flags.

Information about hints for each service will be posted after the game start.

- 2 configs for team members

(*)
If you choose Cloud hosting, you don't need it. Config will be automatically loaded to the your machine. Services can be found in /tasks directory.
