Yes, Mark-1 (Debian Jessie) has a firewall protecting the messagebus port by default. You need to ‚sudo ufw allow 8181‘ to open it.
Okay, but not the rest of the ports, like the one the skill operates on 4445?
I dont remember, maybe i have turned the firewall completely off - will look it up and report back…
I give an idea for you. It would be possible under mycroft.home to set up family names or other and then say “computer spock on the bridge” as in Star Trek or “Hey mycroft Andreas is ready to eat”. it would then also be possible “hey mycroft add andreas to family / company”.
