I would like to access a Raspberry Pi with DietPi 8.3.1 externally via Putty.
I have installed Dropbear and entered my data from https://www.twodns.de/ under dietpi-launcher/misc Dyn.DNS.
Shouldn’t it now be possible to access the device via the IP of the DynDNS provider or the URL?
I am currently installing an RSA key for Dropbear.
You need to check that your external internet IP is registered at your DDNS provider correctly. As well, did you forward SSH port on your router to the DietPi device?
