That's interesting, they gave you some infos like the time and the amount but nothing else ? Seems to me that they're pretty clueless and are fishing in the dark. Another reason for their behaviour could be that they want to get rid of you / your Tor node. Threatening customers is really sad, sounds like they heard the word Tor from you and then concluded "oh, than he basically asked for the attack". > > Now I seek for your interpretation of this event: > - - Has there been more recent incidents against Tor nodes?

Tor Weather doesn't register my fingerprint
by Giovanny Andres Gongora Granada 26 Dec '14

26 Dec '14

Hi, Today I decided to run a Tor Relay and contribute to Tor Project on a Rackspace that I have free for it. I want to use Tor Weather to get notifications about my relay, but when I try to register my fingerprint it doesn't accept it. What could be needed to register it? My fingerprint is: 4C90453B94DAC00BE356283F427CECE024B9D224 This is the info about my relay: https://globe.torproject.org/#/relay/4C90453B94DAC00BE356283F427CECE024B9D2… Regards, Gio -- Mozilla Hispano: http://mozilla-hispano.org Mentor en mozilla-hispano.org: Gioyik <https://www.mozilla-hispano.org/documentacion/Usuario:Gioyik> Mozilla Colombia: Miembro en MozillaColombia <http://mozillacolombia.org/our-contributors/> twitter: Gioyik <https://twitter.com/Gioyik> Blog: gioyik.wordpress.com irc: gioyik

help needed to setup a bridge on amazon and relay on PC

I've been trying to setup a bridge on amazon cloud and relay node on PC but never succeeded in setting it up. I always get an error "Your server (IP:9001) has not managed to confirm that its ORPort is reachable". 1. My PC is behind netgear router and I had configured portforwarding (portforwarding seems to work but tor-relay fails complains about ORPort reachability). 2. Follow the steps https://cloud.torproject.org/#get_started and created an instance on amazon cloud but facing the ORPort reachability.

Tor Relay Operators Meetup at 31c3 - 28.12. 14:15
by Moritz Bartl 23 Dec '14

23 Dec '14

Hi, Torservers.net invites Tor exit relay operators and organizations to a meetup. If possible/relevant, for example if you're a member of one of the 'Torservers partner organizations', please prepare some slides on your activities. You're obviously also welcome to suggest sessions as a member of the broader relay community! We will do quick presentations on recent and future activities around Torservers.net, talk about events relevant to the Tor relay community, and what lies ahead. https://events.ccc.de/congress/2014/wiki/Session:Tor_Relay_Operators_Meetup 2014/12/28 14:15 - 16:15 See you there! -- Moritz Bartl https://www.torservers.net/

DDoS attack targeted on my exit node
by Michael Renner 22 Dec '14

22 Dec '14

Hi, my tor exit node was targeted with two DDoS attacks, one on 2014-12-20 01:00 CET and one on 2014-12-22 18:00 CET [1], both lasting about 5 minutes each. This alone wouldn’t be too noteworthy if it weren’t for the fact that a) there’s a certain state of alarm WRT the Tor networks integrity and b) these are the only attacks my ISP has on record for the over 2.5 years of operating the Tor Exit node. If no other operators have noticed anything out of the ordinary (given by the silence on the list) this is most likely a fluke (getting rid of pesky IRC users?), but better be safe than sorry. best, Michael [1] http://i.imgur.com/Zu9UkW3.png <http://i.imgur.com/Zu9UkW3.png> Summary screen

Hibernation and Guard flag
by Filippo Valsorda 21 Dec '14

21 Dec '14

Hello, I set up a relay node on my VPS to eat up all that unused bandwidth, and it's doing well so far [1]. Since I have ~3TB per month and I heard hibernation is preferable to throttling, I set up monthly accounting with that cap. However I have two doubts: 1. Is daily accounting preferable? That is, what's best, shorter or longer hibernation periods? 2. How does hibernation play with the Guard flag? I know Guards rotation plays a crucial role in users privacy, and it seems to me hibernation would really hurt a client that selected you as its Guard, since it will have either to run with one less available Guard, or pick a new one and increase its risk. Also, I know there are talks about making only 1 Guard selected, how would that play with hibernation? N.B. please cc me into the replies, I might not be getting only-in-list replies. Thanks, Filippo [1] https://globe.torproject.org/#/relay/2EC042F4274CC8A54381C78E8D1BF322FA26A0…
