 - Subfolder 'site2'
 
 To avoid annoying CORS errors, if the PC complains, serve the site through a local server, for instance http-server on node.js
+
+
+
+COMMANDS (most need sudo):
+
+LINUX:
+- lsof  -i:PORT  -->  list processes listening on PORT on linux
+- ss -ltnp  -->  list processes listening on various ports
+- ip a  -->  various machine ips
+- top, nohup  -->  old friends
+- ssh-keygen  -->  generate public/private key pair. TAKE CARE OF THE FORMAT: EGI virtual machines seem to NEED RSA. The public key needs to be saved in /home/USERNAME/.ssh, and to be cat-ed in the /home/USERNAME/.ssh/authorized_keys file. The private key needs to be used by the user wanting to login; on linux, permissions must be 700.
+- journalctl -xe  -->  ???
+
+
+APACHE:
+- systemctl start/stop/restart/reload apache2
+- a2ensite NOMESITO  -->  apache2 command to add 'site' (configuration file NOMESITO.conf in /etc/apache2/sites-available) to sites-enabled
+- a2enmod proxy  -->  command to enable reverse proxy setup in virtualhost (use together with proxy_http)
+- a2enmod proxy_http  -->  command to enable reverse proxy setup in virtualhost (use together with proxy)
+
+
+PYTHON:
+- waitress-serve --listen=127.0.0.42:5000 app:app  -->  example of command to serve flask app (file app.py, app name = app) on the waitress WSGI
+
+
+DOCKER:
+- docker exec -it tigro000 bash  -->  explore Docker image 'tigro000' filesystem (with bash); more generally, docker exec will execute commands on it.
+- docker run -d --name tigro -p 80:80 tigro000  -->  example of running Docker: run image 'tigro000' in container named 'tigro'; expose internal port 80 on external port 80 (-p); detach (-d)
+- docker images  -->  check existing Docker images
+- docker ps  -->  check running docker containers
