Camping Porticciolo, Bracciano (Rome), Italy
After several years using others stable Linux distributions, I changed to Debian mainly for the better support in upgrading the system.
My small net includes 7 PCs; one PC as firewall/router and running squid for the authentication of the guests connected trought wi-fi, 3 PCs for managing the camping, 1 as backup server, two PCs as Internet point for the turists.
