Anyone have any more information on any of this stuff? They claim it's a 0day but I have yet to see proof.

Possible DDoS
by Christian Burkert 26 Dec '14

26 Dec '14

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA512 Hi *, I'm running a non-exit Tor node for a few months now on a virtual server hosted in a professional datacenter. That's the node: https://globe.torproject.org/#/relay/4C246EA9C950B872FD77F761CEAAB41D93D976… Yesterday, December 25th, the support wrote me, that my server is under a DDoS attack with 2GBit/s lasting over more than two hours. So, the hoster black holed my traffic to protect the other customers. The hoster wanted to know which services I'm running and told me that if I continue running Tor and further attacks will happen, then I would have to bear the costs. Eventually, I took down the Tor node to avoid further confrontation. Now I seek for your interpretation of this event: - - Has there been more recent incidents against Tor nodes? - - How can I investigate it? - - How should one react to a hoster? I mean they could have made up the whole thing... Looking forward to your comments Chris -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.12 (GNU/Linux) Comment: Using GnuPG with Icedove - http://www.enigmail.net/ iQIcBAEBCgAGBQJUnUdDAAoJEHAzZ6ooPDSy0nMP/1lyHPPFBxpAOvEiWL+ijrvA SPViJvZH/cPUS/11M7qm+bsZa/fbiRk6kY8ADcY8abe1Z8lHzMYPGwZvKaIijiZG M8hjCHtMWLipO6iLmVfFskDtRn37Ga2ibEhGkVesDV53kPcotgg4i7tIqIuNb11X Gnkk+WpYwkrS9nPZjYNLmce093s4lux/N5GyRY/gQii+h9mfDJ++W+1ueNU94UQ0 bvK1wF7MdicWlu0kR49hCgFtDFh7uUjP87MPZmmQYHI82qWhTJxqOuuImrnJew2k pCFSzn03x/hXg1QFNPNLsqHU9OhUob3/z17Azcpbir15mY4/YE7Gq14/LBM+FKh0 LqGjzaVbQo0hs0kE2yFk5sEP0Dsv5aiOUItqFIMTG52FYZ6cUh/eTxMd6vblHwfU ujil0rFCRqtmbF6wIDBuXDxc0fmdaRMWTDfSlPxYGkfUaq1tSea1OAvjFpheOcNM wu9QiTSq9BTLY010iHSYQDknSr+gFkc/ooNLsPV1AAZFyMlG0epLww6tqR7C9hZq RyEX9piqGal7mU56gETxhDrD0Z/aKgXMbS+KvYfZhopGWEVg5vbWPGxAId53nhr6 hjvLyFmy68hBdbOB/pvp8qvw8veQR3niiHIxhxAl+BIQzXX45x0uVCPHFUpbbLp5 POIwpEJ46oaz7+cddAHf =TcPt -----END PGP SIGNATURE-----

So, > the hoster black holed my traffic to protect the other customers. I've seen this behaviour from some ISP's before and it's rather sad. If something like this happens my ISP is taking care of it without disabling my systems. I'm just getting a note with all the technical information and that's it. > The hoster wanted to know which services I'm running and told me that > if I continue running Tor and further attacks will happen, then I > would have to bear the costs. > Eventually, I took down the Tor node to avoid further confrontation. 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? Nothing with that magnitude on my end for weeks. > - - How can I investigate it? You can ask your ISP for their logs regarding that attack. Do you have any logs on your system, maybe from a intrusion detection or anything else ? > - - How should one react to a hoster? I mean they could have made up the > whole thing... If you are already considering this than i would recommend changing to another ISP, sounds like there is already some distrust. > > Looking forward to your comments > Chris > -----BEGIN PGP SIGNATURE----- > Version: GnuPG v1.4.12 (GNU/Linux) > Comment: Using GnuPG with Icedove - http://www.enigmail.net/ > > iQIcBAEBCgAGBQJUnUdDAAoJEHAzZ6ooPDSy0nMP/1lyHPPFBxpAOvEiWL+ijrvA > SPViJvZH/cPUS/11M7qm+bsZa/fbiRk6kY8ADcY8abe1Z8lHzMYPGwZvKaIijiZG > M8hjCHtMWLipO6iLmVfFskDtRn37Ga2ibEhGkVesDV53kPcotgg4i7tIqIuNb11X > Gnkk+WpYwkrS9nPZjYNLmce093s4lux/N5GyRY/gQii+h9mfDJ++W+1ueNU94UQ0 > bvK1wF7MdicWlu0kR49hCgFtDFh7uUjP87MPZmmQYHI82qWhTJxqOuuImrnJew2k > pCFSzn03x/hXg1QFNPNLsqHU9OhUob3/z17Azcpbir15mY4/YE7Gq14/LBM+FKh0 > LqGjzaVbQo0hs0kE2yFk5sEP0Dsv5aiOUItqFIMTG52FYZ6cUh/eTxMd6vblHwfU > ujil0rFCRqtmbF6wIDBuXDxc0fmdaRMWTDfSlPxYGkfUaq1tSea1OAvjFpheOcNM > wu9QiTSq9BTLY010iHSYQDknSr+gFkc/ooNLsPV1AAZFyMlG0epLww6tqR7C9hZq > RyEX9piqGal7mU56gETxhDrD0Z/aKgXMbS+KvYfZhopGWEVg5vbWPGxAId53nhr6 > hjvLyFmy68hBdbOB/pvp8qvw8veQR3niiHIxhxAl+BIQzXX45x0uVCPHFUpbbLp5 > POIwpEJ46oaz7+cddAHf > =TcPt > -----END PGP SIGNATURE----- > _______________________________________________ > tor-relays mailing list > tor-relays(a)lists.torproject.org > https://lists.torproject.org/cgi-bin/mailman/listinfo/tor-relays -- Sincerely yours / Sincères salutations Sebastian Urbach ----------------------------------------- Definition of Tor: 10% luck, 20% skill, 15% concentrated power of will, 5% pleasure, 50% pain and 100% reason to remember the name! -----------------------------------------

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.

Tor Relay Operators Meetup at 31c3 - 28.12. 14:15
by Moritz Bartl 24 Dec '14

24 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
