Hello is there a any difference between changing tor circut via nyx and pressing n vs tor-ctrl signal NEWNYM ?
no real difference, nyx just talks to the control port for you. pressing n in nyx sends SIGNAL NEWNYM, same thing tor-ctrl does, so both end up as the exact same control command.
worth knowing what NEWNYM actually does though. it does not tear down circuits that still have streams on them, it just stops new streams from reusing the old ones, so anything already downloading keeps going on the old path. and your entry guards dont change, only the middle and exit. so if you are expecting a totally fresh path to the network thats not what you get.
