Alright. Yeah, certbot is mainly for the simple configurations. I use caddyserver.com to automatically get certs and renew them

Alright, not the best solution, but this should be temporary. You're gonna need https://www.cygwin.com/ with python3 and python3 requests, then go to the /cygdrive/c/.../Darwinbots/IM/outgoing in cygwin terminal, and

Code: [Select]
while :; do for bot in $(ls *dbo | shuf | head -n1); do curl -T$bot https://dbim.theblazehen.com/anythinggoes && rm $bot; done; rm *stats; sleep 1; done
Then save the following as im_incoming.py
Code: [Select]
import requests
import time
import random
while True:
time.sleep(0.5)
try:
print("getting bot")
r = requests.get('https://dbim.theblazehen.com/anythinggoes')
botData = r.content
if r.ok:
with open(str(random.randrange(0,1000)) + '.dbo', 'wb') as f:
f.write(botData)
f.close()
except:
print("failed to get bot")

Then cd to /cygdrive/c/Users/.../IM/incoming and
Code: [Select]
python3 /cygdrive/c/path/to/im_incoming.py
You can replace the anything goes with whichever world you want to connect to, so you can easily create your own. Note that per IP you need to stay within a range of -10 to +10 bots uploaded, so you'd be up to 10 quite quickly, then you get 1 point closer to 0 each minute. There needs to be a pool of 200 bots in the world before you can retrieve any, so it requires 200-10 minutes before you can receive anything back from the world.

@Numsgil will you be able to support using HTTP GET and PUT in the darwinbots client directly, or will it still use an external program with an incoming and outgoing directory?

@Numsgil will you be able to support using HTTP GET and PUT in the darwinbots client directly, or will it still use an external program with an incoming and outgoing directory?

Although Visual Basic 6 is supposed to support http libraries, in practice we've had better success with external programs that read and write the files, with the DB2 app just reading and writing files.

...

For the server code, can you explain which abuses you're trying to protect against?

Someone flooding the sim with one of their bots, or grabbing all the bots available in the pool. It tries to keep a balance between bots in / out for each client
