Thanks for your reply. Running a VPS feels great

Yes, and you can do so much more with it! Try this (untested as little time until tomorrow, but approx like that):
sudo apt-get install apache2
sudo mkdir /var/www/html/me
sudo chmod 777 /var/www/html/me
echo "hello world" > /var/www/html/me/hello.txt
Then open your browser at
http://your.ip.address.here/me/ or at
http://your.ip.address.here/me/hello.txtJust one example ...
P.S.: the chmod 777 is dangerously unsafe, but it circumvents access rights problems, until you have learned more about users, groups, chmod, and chown.
