running Tor relay live with AddressSanitizer
by starlight.2013q4＠binnacle.cx 28 Jun '14

28 Jun '14

Has anyone tried running a live relay with an image built using GCC 4.8 and -fsanitize=address? AddressSanitizer documentation says it should be no worse than about x4 on CPU and typically about x2, so it looks reasonable to try. I'm seeing peak CPU of about 7-8% of a 2.2GHz AMD core. I'd probably create a static build, with 'libevent' and 'tor' compiled using -fsanitize=address -O1 -fno-omit-frame-pointer -g per the Google documentation and 'libz' compiled normally since 'zlib' is stable and mature. Any thoughts or experience? Thanks

Need help to get TorDNSEL compiled
by BlueStar88 26 Jun '14

26 Jun '14

Hi there, today I've read about the outage at "check.torproject.org". Since my torcheck-service "torcheck.xenobite.eu" needs the underlying TorDNSEL feature I'm trying to get this to work on my host. Like this I won't need to query the TorDNSEL-part of "check.torproject.org" anymore. I'm not into programming and do not know anything about haskell, c++ and such. So be patient with me on such matters. ;-) I've DL'ed the code from the internet website mirror [2]. I've prepp'ed all the dependencies using lucid binary packages: ghc6 6.12.1-12 libghc6-mtl-dev 1.1.0.2-10 libghc6-network-dev 2.2.1.7-1 libghc6-time-dev 1.1.2.4-2 libghc6-hunit-dev 1.2.2.1-2 libssl-dev 0.9.8k-7ubuntu8.15 libghc6-stm-prof 2.1.1.2-5 libghc6-binary-prof 0.5.0.2-1 First error I got on compile attempt was: src/TorDNSEL/Main.hs:81:21: parse error on input `#' That was quite easy thought: import GHC.Prim (Addr#) I deleted the '#' hopefully making it correct this way. Next error is some numbers too high for me now: src/TorDNSEL/DeepSeq.hs:20:7: Could not find module `Data.ByteString': It is a member of the hidden package `bytestring-0.9.1.5'. Perhaps you need to add `bytestring' to the build-depends in your .cabal file. Use -v to see a list of the files searched for. The libghc6-bytestring-dev-0.9.1.5-125af ist installed by it's main package ghc6 6.12.1-12. Any ideas? Or are there some binary packages for TorDNSEL around, to make this more easy for me? :-P Thanks, BlueStar88 [1] https://blog.torproject.org/blog/tor-check-outage-03-and-04-july-2013 [2] https://www.torproject.org/tordnsel/dist/tordnsel-0.0.6.tar.gz

Checking a bridge
by Martin Kepplinger 08 Feb '14

When my bridge uses only the same few MBs each day, i guess it isn't used at all right? Is there a simple way to ensure it is in bridgeDB and functioning as it should? thanks, martin

Your system clock just jumped
by Jobiwan Kenobi 04 Dec '13

04 Dec '13

I've been running a relay for about months now. It runs on an 1.6 Ghz single core Atom with hyperthreading, 1GB of RAM. It's on my home connection; I advertise only 176 KB/sec. Under normal conditions, it pumps around 100KB/sec, it has around 600 connections, it uses around 20% CPU. Everything looks very healthy. Lately I have seen a couple of incidents where the number of connections suddenly goes up to over 3000, traffic increases heavily, CPU usage goes well over 150% (out of possible 200). Traffic can go up to between 500 and 1000 KB/sec for long periods of time. Sometimes it seems that my relay just can't take it anymore. In the log, the ratio of TAP handshakes goes wild, and I get clock jump warnings. My clock does not jump. This is Tor hanging while allocating memory. Today I had a really bad episode, where the box started thrashing. When it became responsive again, Tor was left in a state where it was constantly downloading about 400KB/sec more than it was uploading. Normally I have a little bit more up than down, because I'm a directory server as well. I can not explain having a lot more down than up. I can fantasize that those hangs/clock jumps ("assuming established circuits no longer work") could leave 'half' circuits. Finally I restarted my relay, (which I really don't like to do) and after a while it stabilized. At this point, my router shows a peak of almost 8000 NAT sessions. Is this normal behavior of the network (esp. the sudden increase in connections) or is this another kind of attack/probe like what we've seen in early September? Is this because this machine is just too underpowered? Should I collect/provide any diagnostics? Have others seen similar events?

Proper bandwidth units [was: Exit nodes on Gandi]

People, can we please mind using the proper units. I know Tor doesn't make it easy because Tor itself incorrectly uses Bytes. But Tor is a network application, and real network apps are measured in 'bits per second', not 'bytes transferred off disk', even if the latter is what silly hosters sell by... mostly due to their presumed need to tie in with their typical customers supposed Apache access_logs. But believe me, what hosters really care about is their upstream bill in bps rate, they're just converting that for access_log presentation to you. Your further mixing of 'giga bits per month' doesn't help *at all*. Please try to use 'bits per second' as the common denominator on this (network application) list. BTW, Gandi is historically a fairly progressive company. The right approach could have some good wins there.

Newly configured relay questions
by Conrad Rockenhaus 01 Dec '13

01 Dec '13

Hello all, I brought a new non-exit relay online: ec2bridgerocks001 D06C B145 56C1 F73A F317 B555 C279 2F7B 105C 95B4 It's been operational for 6 days now, Tor has been reporting bandwidth usage, but when I try to look for it in the TorStatus page, it's not listed. I'm operating this relay on EC2 and I've opened all the usual ports. I've also checked the Tor metric portal, can't find it there either. So, I'm wondering - is there something I missed in the configuration? The torrc is pretty much the default EC2 one. Thank you I appreciate any thoughts/assistance. Respectfully, -- Conrad Rockenhaus http://www.rockenhaus.com/ http://www.lagparty.org/~conradr/

Named flag
by Sebastian Urbach 28 Nov '13

28 Nov '13

Dear colleagues, Im a bit confused about the "named" flag. My relay is running smooth and i already received the "guard" flag but still no named flag. I also read the directory specification paper. I dont have the unnamed status nor is there another server with that name in use. Im not sure if the authority supports name binding but from what i understand the authority should support it. Maybe someone on this list is able to look into that matter ... Router Name: ParEpistemenTaksis Fingerprint: 3C82 285F AC21 71FA 5178 340A 82B0 5F21 90AB 68E9 -- Mit freundlichen Grüssen / Sincerely yours Sebsstian Urbach ----------------------------------- Religion is a symptom of irrational belief and groundless hope. ----------------------------------- Gregory House, M.D.

Huge harrassment by Irdeto and IP-Echelon, 83 mails, in 2 weeks, need your help
by julien.robin28＠free.fr 19 Nov '13

19 Nov '13

Hello everybody, My 2 exit nodes servers are ArachnideFR35 and ArachnideFR35v2, with respective observed bandwidth of approximately 100Mb/s and 30 Mb/s (12 200 KB/s and 3800 kB/s). They are momentarily down since I have decided today to put them down while I will be trying to solve this enormous Irdeto/IP-Echelon problem. I want to keep my servers alive but I realize that it will not be possible if harassment doesn't stop quickly. My ISP is just transmitting to me a huge amount of abuse complaints every day (and never makes any comment) but they are too many and the incredible patience of my ISP cannot be unlimited. And all this, despite of the fact that my reverse DNS are set, since the first day, to http://digi00277.torproxy-readme-arachnide-fr-35.fr and http://digi00433.torproxy-readme-arachnide-fr-35.fr with the Tor Exit Notice on port 80. And it is this address that appears into the Tor Relay lists. I have decided to temporarily shut down my servers today (November 13, 2013, 14:50 UTC) while I'm trying to solve this enormous Irdeto/IP-Echelon problem, and to send a mail to my ISP to tell them that I will try to fix this problem before to restart my servers. Since August 18, 2013, the two machines that I'm running as Tor Relays are full exit nodes (reject *:25, *:26, *:27, accept *:*) (before it, since May 2013, they was only Relays nodes) because I was thininking that : if there is abuse complaints, I will be able to face them. I'm not the only one in this case (accept *:*), But as I see in this mailing-list it seems that the amount of abuse complaint I'm receiving is completely abnormal. My service provider is Digicube.fr, it's a really little company that doesn't seems to be able of handle everything in time. I not sure if there was no abuse complaints before end of October, but if there was, I never seen them. I have tried everything: by mail or by the Web Interface that figures in the mails, with all these arguments: - Since 08/18/2013, 95.130.10.70 and 95.130.9.89 are dedicated high speed Tor Exit Router, they do not host or share anything, they are just international network routers with empty hard disk drives. - All reports you sent about these permanent IP Addresses (95.130.10.70 and 95.130.9.89) for several weeks are wrong: the IP Address that appears into your reports is the IP Address of the router, not the user. - These routers and his responsible are NOT infringing any copyright. Neither technically nor legally. - You got to understand that the goal of such a network is a way much fair goal than movies on the Internet. In March 2011, the Tor Project was awarded the Free Software Foundation's 2010 Award for Projects of Social Benefit on the following grounds: "Using free software, Tor has enabled roughly 36 million people around the world to experience freedom of access and expression on the Internet while keeping them in control of their privacy and anonymity. Its network has proved pivotal in dissident movements in both Iran and more recently Egypt." But for both Irdeto and IP-Echelon, they don't care, and every day, the harassment procedure continues. I think they don't read my emails, I hope they can receive them; I never had any answers from them. I told them that if there is no answer, I will not have any reason to keep watching their emails... may be I need to ask my ISP to put a spam-filter about that, but I think that such a proposal have no chance to be welcome into an abuse service ! Don't be horrified: here is, below, the list of all abuse complaints I've received from them. You will understand why I love my ISP, and why I need to quickly find a solution!

Thank you in advance, Arachnide needs your help ! Best regards, Julien ROBIN PS : I will be at work the entire day tomorrow, sorry if I don't answer before tomorrow evening.

Apologies for the email about Sugarcube
by Sriakhil Gogineni 19 Nov '13

19 Nov '13

Hello all, I'm very sorry about an email that went out yesterday that some of you received. It was only supposed to go to my contacts, around 2000 people. I exported my contacts and removed all mailing lists from the pool but it seems some people who were cc'd on threads got added in. It seems I have deeply offended about a dozen of you and for that I'm sorry. I know how precious inbox sanity is and I did not intend to spam anyone -- this email was only supposed to go to family and friends. Rest assured there is no 'list' and you will not be receiving any future email from me regarding Sugarcube. Best, Sri
