I have used Tor for a while in the past, and just started to use Whonix recently (with VirtualBox). I can’t seem to understand or find extensive documentation for Arm (Tor Controller).
My questions are mainly regarding the connections / circuits (page 2) in arm in Whonix-Gateway:
Why does it display so many circuits? is there a way to refresh this list to include only active / current circuits? when I just start the Tor Browser in the Workstation, I already see 4 different circuits. When I use several tabs, then close all but one, I still see many circuits, all of them show the same number of seconds / minutes.
How can I easily identify the last circuit opened? for example, if I open a new Tab in the Tor browser in the Workstation, where exactly does it appear and when?
I noticed a few times that instead of 3 nodes (Guard-Middle-Exit), I got 4 nodes in some of the circuits (Guard-Middle-Middle-Exit). In which cases does that happen?
