Assume you run a webserver on your local machine. You configured it as hidden service. In the morning when you wake up. you turn on your computer and the hidden service is available to the world. Before you go to bed, you turn off your computer and the hidden service disappears. An attacker can send requests to your hidden service to check if it is online. He will learn that it is turned off for some hours and online for some hours. With this information he knows (or can assume) in which timezone your computer is located and maybe some more. > Also, does one need to be connected (online), to the Tor network in > order to "precheck" a Hidden Services site in order to make sure it is > working properly? Can it open in Firefox browser offline and whatever You need to be connected with the Tor Network, because your software needs to connect to certain servers (introduction and rendezvous points, i.e.). regards, -- Jens Kubieziel http://www.kubieziel.de Wer viel Charakter hat, hat wenig Eigentum.
