Title: Tor always connects to same 3 entry nodes and they cannot be blocked
Post by: masterblaster on August 01, 2012, 07:32 pm
Attempted to edit my torrc config file from within the control panel gives an error, even if i just open it up and save it. If i try to boot up tor after making changes to the file itself then it gets overwritten with a default one, if i switch the modified file with the default one while tor is running then it will show up as being used but will not work. I've been trying to use this with no success:

ExcludeNodes $fingerprint,$fingerprint,...
    A list of nodes to never use when building a circuit.

Anyone else seeing similar behavior/nodes from tor? This shouldnt be happening.

You beat me to it! Tor reuses entry guards to help protect you from being profiled via traffic correlation: https://www.torproject.org/docs/faq#EntryGuards

Oh, it seems like reusing the same entry's would let an attacker gain advantage by profiling the traffic coming through it.
