Dear readers !
For my relays I looking for a torrc parameter to reduce the circuit live time from default of 10 minutes to about 5 minutes.
My intension: I dont' know is the point of time to switch the path between relays synchronized. An overlap (or different switching time) will reduce the path live time to less than 10 minutes. This is ok for me, because the circuit analysis time for attackers is less than 10 minutes (traceroute...). Synchronized relays keeps a whole circuit path open for 10 minutes, from guard to the exit. Am I right?
Am I right with my intension to change the default circuit live time or is this not necessary? A short answer would be ok.
Assuming torrc parameter: MaxCircuitDirtiness NUM (Default: 10 minutes)
The backgroud of the story (and why I want to generate more noise):
Last year, on July 19, my exit relay was seized at home. I knew about the danger, but I ignored it. According to the police, my relay was abused for about 5 months, again with the same (evil) web server as the target. I am assuming my Exit Relay was explicitly selected as an exit. To protect the relay operators, you might want to remove this function. A targeted compromising of an operator must not be possible.
The police photographed some of the current connections displayed with ARM. A test with ARM showed an indication of a seemingly complete circuit from the guard to the exit. I see Source -> Target, Guard, Middle, Exit. I'm not sure, but I get a bad feeling.
Please tell me that my interpretation of the displayed content in ARM is wrong.
For the time being, I only have 2 Middle nodes as VPS online. Later, after the completion of the law procedure, I switch the two VPS middle nodes back to Exit Relays (Provider Keyweb and FlokiNET). The third middle node at home remains only a middle node. I swear this.
Best regards!
