Right now, in the default torrc ( https://gitweb.torproject.org/tor.git/blob_plain/HEAD:/src/config/torrc.sample.in ), it is said : ## Uncomment this if you run more than one Tor relay, and add the identity ## key fingerprint of each Tor relay you control, even if they're on ## different networks. You declare it here so Tor clients can avoid ## using more than one of your relays in a single circuit. See ## https://www.torproject.org/docs/faq#MultipleRelays #MyFamily $keyid,$keyid,... However, as rransom pointed out to me, bridges should NEVER see their fingerprints set in the MyFamily setting. rransom | DO NOT include a bridge's fingerprint in any Tor instance's MyFamily torrc line. rransom | Anyone can use a bridge's fingerprint to find its current TCP address. This should be clearly enunciated both in the torrc file AND in the FAQ ( https://www.torproject.org/docs/faq#MultipleRelays ) to be sure to avoid any user error. **Trac**: **Username**: koolfy
