Re: [tor-relays] Consensus weight dropped

2015-01-31 Thread Bram de Boer
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.

 Give it a day or two, and see if only tor26 and moria1 measure it.

 In fact, both the 7C3AE76BB9E9E6E4F2AE9270FD824DF54A944127 and
 E6D740ABFFAAAD8052EDF95B2C8DC4059763F365 relays operate on the same IP
 address. Both dropped to 0.00%.

 However, other nodes in the same AS16265 are doing fine (e.g.
 B144DC5C08AF1FB3ABD729AFC2CF938CF63F78AC). This seems to suggest that the
 route between the bwauths and the relay is irrelevant and connectivity is
 not an issue.

 I can imagine that an overloaded bwauth occasionally skips a few relays.
 But wouldn't that be corrected automatically during the measurement the
 next day? Given that the relays are missing votes consistently during many
 consecutive days, some other mechanism must be causing this.

 Would a quick-fix be to randomize the order in which relays are measured?
 That way, if a bwauth has trouble processing the entire list in 24h, every
 day other relays are given a chance?

 Thanks,
 Bram

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. So I hope someone with more knowledge is reviewing
this case and post a solution or declare it as a general probleme and
write a bug report.

I am the operator of the bandwidth authority reporting to maatuska. This

This should not have been a big deal, but since two other bw auths

My dropping consensus overlaps exactly with the blue line on that graph 
time-wise. The 1 Month Graph shows this pretty well.


https://atlas.torproject.org/#details/3D7E274A87D9A89AF064C13D1EE4CA1F184F2600

It feels as if I am almost completely dependent on that blue node, 
although since one needs multiple measures, it shouldn't be possible.

You could start a second relay on the same physical machine on a
different port and see whether the bandwidth scanners pick that up.
Give it a day or two, and see if only tor26 and moria1 measure it.

You can find out the latter by fetching the latest votes from all
directory authorities and searching for your nickname and subsequent
w lines in them:

https://collector.torproject.org/recent/relay-descriptors/votes/

And of course you'll notice on Atlas whether the consensus weight
fraction of your new relay will be 0.0% or not.

It feels as if I am almost completely dependent on that blue node,
 although since one needs multiple measures, it shouldn't be 
 possible.
 
 Ah, sorry for being unclear.  The blue line is not bandwidth
 authority number 4, it's the number of relays for which there are
 measurements from 4 bandwidth authorities.
 
 But here's another graph, specifically for your relay schokomilch:
 
 https://people.torproject.org/~karsten/volatile/schokomilch-cw-2015-01-21.png

 
 
 14C1 is tor26, 4901 is maatuska, and D586 is moria1.  It looks
 like maatuska stopped measuring your relay between December 29 and
 January 5, which is a general problem with maatuska's scanner, not
 specific to your relay, AFAIK.
 
 And unrelated to this, neither gabelmoo nor longclaw ever measured 
 your relay.  I'd say this is something to investigate and then
 fix.
 
 All the best, Karsten

 Yes, it dropped from 0.193553% to 0.00%

 Please post your relay fingerprint(s) here, and I'll investigate this.

 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. Grr.

Re: [tor-relays] Consensus weight dropped

2015-01-20 Thread Network Operations Center
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.

The votes from the directory authorities for the last consensus period
are here:
http://freehaven.net/~arma/moria1-v3-status-votes

In this case it looks like schokomilch has these votes for the w line:

w Bandwidth=2525 Measured=1600  [moria1]
w Bandwidth=2525[dizum]
w Bandwidth=2525[Faravahar]
w Bandwidth=2525[gabelmoo]
w Bandwidth=2525[dannenberg]
w Bandwidth=2525[urras]
w Bandwidth=2525[longclaw]
w Bandwidth=2525 Measured=674   [tor26]
w Bandwidth=2525[maatuska]

So since only two directory authorities vote a Measured value for it,
and the design calls for three opinions, it ends up unmeasured, and 
thus

with a consensus weight of 20.

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.)

figuring out what happened will likely involve looking at the directory

If all consensus weights dropped by a certain factor, there's no

Hello,

You are not alone with this issue (

amount and then dropped back to 20. So far there is no helpful response 
regarding this subject.
