Re: [tor-relays] Consensus weight dropped
All, Consensus weight of my relays and those of others is still near zero, and not improving. For a network that attempts to break censorship, it is peculiar that this is getting so little attention. Apparently a few malfunctioning bwauth systems is enough to censor specific Tor relays. Endless research and development effort is put in tweaking and optimizing the relay-to-relay communication, but having only a few systems in the world that determine the consensus weight of the entire network does not seem to trouble anyone. Wierd. I hope the bwauth operators can find a way to correct the problem. I am feeling silly spending good money on a high-end server with unmetered bandwidth that has now been relaying a whopping 300 Kb/s on average during the last five weeks. Thanks, Bram Thank you all for looking into this. Karsten wrote: You could start a second relay on the same physical machine on a different port and see whether the bandwidth scanners pick that up.

Re: [tor-relays] Consensus weight dropped
Hello List, at this point I want to thank Bram de Boer for spending an unmetered server. Dediacted servers with unmetered network is not cheap and should be treated differently as a virtual server at OVH. I can totally agree why he is disappointed about that. Just deleting the identity is not a solution for me. The identity of a server is also a certificate of the spend effort. If something like that would happen to my relays I would be out of here. Especially I'm not using Tor at all but want to help people who can not access the web like I can do. I recently tried to check why the consensus dropped by reviewing the votes data and digged into the source but my knowledge about that is far below the average.

Yeah we knew about it actually, ot was discussed extensively but in a different context. We knew that each dirauth misses up to 40% of all relays in absolute amount, which means it misses an unknown amount of bandwidth.

Re: [tor-relays] Consensus weight dropped
Very thorough explanation, thanks. I assume that there is nothing I can do except wait until a.) a new BWauth script is being introduced or b.) hope that a third node rediscovers me and once I have 3 votes in the bag I'm back on track. What still confuses me is why several nodes were being dropped by the BWauths all on Dec 28. Then on Jan 6th all of the affected nodes have been rediscovered for a day. I tracerouted all of the BWauths and I don't have trouble sending ICMP packets to said hosts, so it doesn't seem routing related.

You can read about the reasoning for requiring Measured votes here: https://trac.torproject.org/projects/tor/ticket/2286 In theory gabelmoo and longclaw are supposed to have opinions about your relay too: https://consensus-health.torproject.org/consensus-health.html#bwauthstatus But they don't, so here we are. The problem is likely that the bwauth (bandwidth authority) scripts are old and buggy and unmaintained. See https://trac.torproject.org/projects/tor/query?status=!closedcomponent=Torflow especially the tickets towards the bottom. We've already known about this in the context of the bandwidth authority scripts are very poorly tuned for the changes that have happened in the Tor network since the scripts were written, so they vote wildly varying numbers for relays. But I don't think that we'd realized the some relays don't get three votes at all, so they basically get zeroed out issue. Hm. (Ultimately I am hoping for the bwauth scripts to get phased out, in favor of one of the secure bandwidth measurement schemes that various research groups have been working on lately. Those other designs also will have the advantage that it's harder to game the system by lying about your bandwidth. But it will be some months at least until we have one of those designs to evaluate.) --Roger ___ tor-relays mailing list tor-relays@lists.torproject.org https://lists.torproject.org/cgi-bin/mailman/listinfo/tor-relays ___ tor-relays mailing list tor-relays@lists.torproject.org https://lists.torproject.org/cgi-bin/mailman/listinfo/tor-relays

Hello, You are not alone with this issue ( https://lists.torproject.org/pipermail/tor-relays/2015-January/006055.html ).
