Problem description:
After trying to install Jackett and make it run through /etc/init.d/, I can't SSH anymore. Trying rebooting, but lost access to it.

I get "ssh_exchange_identification: read: Connection reset by peer" all the time.

All services are up and running (Couchpotato, Sickrage, Transmission, VNC, Kodi), but I can't ssh to try to solve this.

Is there anyway I can run commands other than SSHing?

I've tried shutting down Kodi, but it loads back automatically. Tried cleaning my Mac's known_hosts.

I can access Kodi through VNC, but hadn't find a way to run commands through the GUI.

Is there anyway?

Thanks in advance!
