replace TCP timestamp

[proper]

The JonDonym documentation ​states, "[...] TCP timestamps can be used for tracking [...]" and "The JonDonym mixes automatically replace your potentially insecure TCP packets by their own.".

Tor should probable do the same or state somewhere why they believe why it's not necessary.

_{Sorry, if this is a duplicate or elsewhere documented. Search term site:torproject.org TCP timestamp or similar didn't bring results.}

If I understand their web page correctly, Tor does this automatically just like the Jondonym mixes do. It's a property you get for free by terminating the underlying traffic flows at each hop rather than packaging up IP packets and sending them across the network.

See e.g. https://trac.torproject.org/projects/tor/wiki/doc/TorFAQ#DoesTorresistremotephysicaldevicefingerprinting

Though, ugh, the faq entries around that on the torfaq have been overrun by idiots. I wonder if I should transfer that particular faq entry over to the 'real' faq.

arma: I think that could be a clever thing to do

How was this fixed? @Sebastian

[Sebastian]

I marked it fixed because we moved the faq entry.
