Try a power supply that can deliver a reliable 5.1V at 2.5A.

Re: Debian 9 to RPI3 - RDP connection? What to use?!!!

There's two ways to run RealVNC. For the start at boot time, you need to configure the machine to boot to GUI (even if you don't use it) you may also need to use

Code: Select all

hdmi_force_hotplug=1

You won't find a crystal ear piece today but I guess some mobile ear buds or whatever would do.
ebay.co.uk had at least one listed. Took me back to the days of our crystal sets and the crocodile clip that we used to clip to the metal dial on the phone as that got us a good free antenna.

Re: Debian 9 to RPI3 - RDP connection? What to use?!!!

Ditch vnc, ditch xrdp. Use RealVNC viewer on your PC, use RealVNC server (already installed) on your RPi. It's possible to run it the other way round with the VNC viewer on your RPi and the server on your PC.

RealVNC works better and is orders of magnitude more secure.

Re: Is UFW preventing access to apache, or is setup wrong?

If you get 403 that's coming from your webserver nothing to do with ufw.

Take a look in /var/log/apache2/ at the access log and error log in there.

Re: Problem re-installing weather station software

php5 is a version (compare it to php7 which is in Stretch) php5.6 is a release of version 5. Just install the latest on Jessie. sudo apt install libapache2-mod-php5 php5 php5-cli php5-mysqlnd phpmyadmin I've only included phpmyadmin as it makes mucking about with MySQL things easier (it's optional).
