While testing, sometimes it's nice to try it in a more 'real' environment (or you're using this project for red-teaming). Before deploying the default LaikaCNC target to a public-facing VPS, we'll need to make some changes.

Generate a good keypair

Make sure you have a unique, self-generated keypair. You can do that by following this.

Pass port && ip back to cmake

This step can be combined with the compilation after you generated your keypair. Just set the LAIKA_CNC_IP and LAIKA_CNC_PORT configs in cmake, like so:

cmake -B build -DLAKA_CNC_IP=127.0.0.1 -DLAIKA_CNC_PORT=13337

Make shell keypair

This keypair is unique per 'admin' user. Generate another keypair and update shell.ini && server.ini

Replace the pre-existing keypair with your newly generated key!!

Example shell.ini

; replace these!!!!
[auth]
public-key = 2d89362e935f96ab967938a279c786958cd4d2f5e6a05c8e2cdee916042f8700
private-key = a8e25e49ffb13b2e1beb90b15ce3a4f1f037e2409af822aab138cdbd9927c468

Example server.ini

Deployment

Note that the CNC target expects 'server.ini' to be in the working directory. If you need to more this file for whatever reason, the ini config path can be passed to the server as a command line argument. Eg:

$ ./bin/LaikaCNC /root/server.ini
