Command and Control

Hackers often use this approach when taking control of computers. They create their own CnC server which issues commands to its slaves. Our program uses a similar approach for handling automatic updates. You can run the CnC server with:

./comix cnc

It will default to port 1337, but you can change it like so:

./comix cnc --port 4242

The following environment variables also must be set:

• COMIX_REDISADDRESS
• COMIX_REDISDBNUMBER
• COMIX_UPDATEDISTRIBUTIONURL

With this running, you can update the command you run on your raspberry pi to (be sure to change ip address!):

./comix-pi downloader --source xkcd --cnc 127.0.0.1:1337 --client-id 123

The CnC service can also be run with docker.
