Congrats, now you should have a running Raspberry Pi and now all you need to do to securely remote access and control it is to setup remote.it!
If you haven't already, make sure you have your Pi connected to your LAN via Ethernet and you have SSH'ed into it from a computer on the same LAN:
Before you start, make sure to update your Pi's software by running the following on the command line which connected to your Pi:
sudo apt updatesudo apt full−upgrade
Now that you are all up to date, it is time to install the remote.it connectd software which lets you configure services on your device to connect to via remote.it. Run the following to install the remote.it connectd package.
sudo apt install connectdsudo connectd_installer
Now you should see an interactive installer menu that will guide you through the process of configuring remote.it to access the various TCP services on your device. Follow the link below for more details on using connectd_installer.
