obfsproxy not working on bridge relay
by jchase 08 Oct '14

08 Oct '14

Hi, Due to m limited bandwidth I've decided to turn my relay into a bridge. I seem to have everything right except if I restart tor I get a warning that "managed proxy obfsproxy is 'closed'". I'm sure this has come up in the past but I can find it in the archives. In torrc I have: SocksPort 0 ORPort 9001 Exitpolicy reject *:* Log notice file /var/log/tor/notices.log Contact info [] Nickname rasptorholland BridgeRelay 1 ServerTransportPlugin obfs3 exec /usr/bin/obfsproxy managed ServerTransportListenAddr obfs3 0.0.0.0:9030 DisableDebuggerAttachment 0 Both ports are forwarded, though I can't find proof that tor is actually using port 9030. Any suggestions? -J. Chase

Trying Trusted Tor Traceroutes
by Sebastian Urbach 08 Oct '14

08 Oct '14

Dear list members, We are happy to present the preleminary analysis results from TTTT: http://arxiv.org/pdf/1410.1823v1.pdf The conclusions are: 1. We have found that AS-path prediction techniques significantly overestimate ASes and IXes traversed by Tor traffic, calling into question the results of previous evaluations of the network-level adversary threat. 2. Our simulations show that Tor may currently be less vulnerable to an AS or IXP adversary than has been previously found. We also find that proposed path-selection algorithms to avoid a network adversary still leave a significant chance for users to be deanonymized over time due to the errors in path prediction, and these algorithms lead to significant rates of connection failures, even though in the large majority of cases the failures could be avoided with better measurement. 3. Thus our results suggest the importance of accurate measurement both for understanding Tor security and for improving it. -- Mit freundlichen Grüssen / Sincerely yours 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! -----------------------------------------

Less Traffic on my relay
by Tor Zilla 07 Oct '14

07 Oct '14

Hi All, I am a noob to the Tor community and its fun serving Tor as one of the relays. I am planning to setup multiple relays however before i jump into anything further i setup one machine as a non exit relay to test how much traffic i can route.. Not to forget i also read the article on torproject.org which mentions the life cycle of a relay.. Now its the 4th day of my relay and the traffic is almost nothing but as per the article i must see an increase in traffic on day 4.. The machine is ON for almost an hour now and the traffic is too less. Received : 3.62MB Sent : 1.6MB My dedicated bandwidth to Tor is 60 KB/s.. Do i need to keep the machine on 24/7 because as of now its just ON for 3 to 4 hours.. Assuming that the traffic is low on the entire Tor network is this kind of traffic normal or something is wrong on my side..? Your help will me much appreciated.. Thanks and Regards, Torzilla11

Tor metrics regarding bridges running transports
by Jan Nielsen 07 Oct '14

07 Oct '14

Hi all. I was wondering if these metrics exist? I couldn't find anything on tor metrics. They list the amount of users using transports but there is no information regarding the number of bridges running particular pluggable transports.

My relay hibernated unexpectedly
by Derric Atzrott 07 Oct '14

07 Oct '14

Hello all, I recently set up the relay zelltor. I just got a notification that it went down about 10 hours ago. From what I can tell it looks like it decided to hibernate and that it will be hibernating for the rest of the month. I think I may have configured something wrong because this was rather unexpected. I want it to hibernate at a certain point, but I do not think its reached that threshold yet. Arm tells me: Accounting (hard) 15 MB / 250 GB 598 KB / 250 GB Time to reset: 31:02:20:23 I have the following configured in torrc: AccountingMax: 250 GB AccountingStart: month 3 15:00 Tor's log files: [notice] Configured hibernation. This interval began 2014-10-03 15:00:00; the scheduled wake-up time is 2014-10-03 15:00:00; we expect to exhaust our quota for this interval around 2014-11-03 15:00:00 (all times local) [notice] Commencing hibernation. We will wake up at 2014-10-03 15:00:00 local time. [notice] Heartbeat: Tor's uptime is 3 days 12:00 hours, with 0 circuits open. I've sent 6.08 GB and received 6.08 GB. We are currently hibernating. [notice] TLS write overhead: 6% [notice] Circuit handshake stats since last time: 2039/2039 TAP, 753/753 NTor. [warn] eventdns: Address mismatch on received DNS packet. Apparent source was 216.69.185.43:53 [notice] Heartbeat: Tor's uptime is 3 days 18:00 hours, with 0 circuits open. I've sent 6.08 GB and received 6.08 GB. We are currently hibernating. [notice] TLS write overhead: 6% [notice] New control connection opened. Note: I stripped the timestamps out because I am viewing these on a different computer and had to retype them. My ISP caps me at 500 GB up+down data per month, which is why I've capped it at 250 GB. I was planning to adjust that down a little bit as needed when my next month's bill came in and I got to see how much overhead Tor produces above the 500 GB cpa. Clearly I've come nowhere close to that though, so I don't think my node should be hibernating yet... Any ideas? Thank you, Derric Atzrott

Arch Linux packages?
by Eric Hocking 05 Oct '14

05 Oct '14

Hi all, I looked through the Arch Linux repository, and wasn’t able to find any packages for Tor or arm. Does anyone use archlinux that could create a package for Tor and arm?

French Flag
by Sebastian Urbach 02 Oct '14

02 Oct '14

Hi, I saw that a lot of services around tor are using a bright blue in the french flag. It should be a dark blue like the one used in the Dutch flag for example ... The following services are concerned: Atlas Globe Compass Oniontip (already fixed, thanks Donncha) If there are more services around that i don't know about then i would like to ask if someone could check them as well. It hurts a bit to see the Tricolore like that ...

Re: [tor-relays] scramblesuit
by Jan Nielsen 02 Oct '14

02 Oct '14

When I restart tor with that option enabled I get: " 2014-10-02 00:52:38,199 [WARNING] Obfsproxy (version: 0.2.3) starting up. 2014-10-02 00:52:38,199 [INFO] Entering server managed-mode. 2014-10-02 00:52:38,200 [INFO] No transports launched. Nothing to do." I noticed it says version 0.2.3 starting up. $obfsproxy --version gives me O.2.12 Why is tor starting the old version? This must be the reason it is not working since scramblesuit was only rolled into obfsproxy in version 0.2.6 . How do I get $sudo service tor start To start obfsproxy v0.2.12?

Scramblesuit
by Jan Nielsen 02 Oct '14

02 Oct '14

Hi. I am trying to enable Scramblesuit for my bridge. I am wondering if there is a method to verify that it is working, similar to how obfs3 shows "registered server transport". There is not much out there about scramblesuit but there is one mention that the log should show " registered server transport scramble suit". Tor version is 0.2.5.8-rc Obfsproxy version 0.2.12 ExtORPort auto ServerTransportPlugin obfs3,scramblesuit exec /usr/bin/obfsproxy managed Oct 01 03:03:28.000 [notice] Registered server transport 'obfs3' at ' 0.0.0.0:39491' Is there something wrong with my config? Thank you.
