THIS PROJECT IS NOT A PRODUCT but rather an improvisation for the sake of learning and fun. Do not expect it to work for you or to be somewhat close to production quality.
A simple HTTP server which allows to wake up a server that has Wake On Lan feature enabled.
In 2022, 2nd & 3rd of June were public holidays in the UK. It supposed to be only one holiday but this year, in addition to the Spring Bank Holiday, the country celebrated Queen's Platinum Jubilee. That left only three working days on that week, and on 1st of June I felt like I have unused energy to spend doing a silly project to have some fun.
To make things interesting, I shall not use any of the tools I use day to day. I always liked C/C++ although, I don't have production experience using those, I have purchased a few books to learn them and the time has come to try something. I've tried modern C++ a few times already so decided to go with plain C this time.
I didn't want to mess around with tooling and environment setup, so I've chosen Clion IDE with an intention to see how it's doing (I've used it a few years ago) and with a hope it will sort most of the stuff out for me.

- A bit of StackOverflow - not going to lie here, but I've tried to use it only as the last resort.
TODO: there is for sure a room for improvement!
Use ReleaseAarch target to build the binary on the Raspberry Pi server.
Note the target directory, it will be something like /tmp/tmp.2gOYvaraa/cmake-build-releaseaarch.
I couldn't figure out how to do cross-compilation on my Mac so here we are. Probably, should have used Docker for that tho.
SSH to the server the copy files from it to the web folder:
cp BUILD_DIR/awakener /var/www/awakener
cp -r BUILD_DIR/public /var/www/awakener
sudo chown -R www-data:www-data /var/www/awakener
sudo chmod 700 /var/www/awakener/awakenerThe process runs via supervisorctl with awakener.conf config. If changed, upload it to /etc/supervisor/conf. d/awakener.conf and then:
sudo supervisorctl reread
sudo supervisorctl restart awakenerEven tho it's a standalone web server it runs behind lighttpd and the config is lighttpd.conf. Put its content
into /etc/lighttpd/external.conf. Validate the config:
sudo /etc/init.d/lighttpd configtestRestart lighttpd:
sudo /etc/init.d/lighttpd reload
