Need Routing Info on Relays
by Tor Zilla 09 Oct '14

09 Oct '14

Hi Folks, I am trying to figure out how the packet flows over a Tor network.. There is a mix of information.. Some claim that the ISP is not aware of the payload as the complete data is encrypted whereas some say that your ISP is not used at all when using Tor network. AFAIK my packets go to the outer web via my ISP and there is no way to by pass that. I might be wrong. Can someone give me a detailed packet flow? Thanks, Torzilla11

Re: [tor-relays] . obfsproxy not working on bridge relay
by Jan Nielsen 09 Oct '14

I believe that error means obfsproxy was either not installed correctly or your torrc is not pointing to the correct location. Follow the below link's instructions. Also, a quick google search for that error provided resukts from this mailing list. Follow its instructions as well. https://lists.torproject.org/pipermail/tor-relays/2014-February/003892.html On Oct 8, 2014 6:00 AM, <tor-relays-request(a)lists.torproject.org> wrote: > Send tor-relays mailing list submissions to > tor-relays(a)lists.torproject.org > > To subscribe or unsubscribe via the World Wide Web, visit > https://lists.torproject.org/cgi-bin/mailman/listinfo/tor-relays > or, via email, send a message with subject or body 'help' to > tor-relays-request(a)lists.torproject.org > > You can reach the person managing the list at > tor-relays-owner(a)lists.torproject.org > > When replying, please edit your Subject line so it is more specific > than "Re: Contents of tor-relays digest..." > > Today's Topics: > > 1. obfsproxy not working on bridge relay (jchase) > 2.

Bridges and advertised bandwidth
by Jan Nielsen 09 Oct '14

09 Oct '14

Hi everyone. I am currently operating 4 bridges on VPSs. They all appear to working correctly. However, 2 of the 4 bridges have 0kb/s as their advertised bandwidth while the other two are advertising around 100KB/s. Is there a reason for the 0kb/s? Does this indicate an error in my bridges or simply a gitch? See this for reference. https://globe.torproject.org/#/search/query=acrossthebridge Thank you.

Hello, Thanks for your advice! I had installed obfsproxy with apt-get on a Pi. I removed that and tried pip. It took me a while to find out that pip was actually python-pip. (Maybe the Tor website could be more specific about that.) That install went well. You asked me to see what happened after the command '/usr/bin/obfsproxy managed'. It took me a while to find that obfsproxy was installed in /usr/local/ , not in /usr/bin/ . And now, until further notice from tor, things seem to work fine. Thanks, J. Chase

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
