Re: [tor-relays] Tor Consensus Weight Stuck at 20 (Even on Relay with Stable Flag)

2015-05-14 Thread Speak Freely
From my experience, this happens only with exit relays. Changing from
an exit relay to a guard fixes the problem immediately.

I've seen past threads that mentioned deleting your id key would fix
the problem, but that never fixed it for me. But that is also
counter-intuitive given that going from exit to guard while keeping
the same id fixes the problem. If I recall correctly, going back to
exit causes the problem to re-appear - I will see if I can confirm
that again with one of my guards-that-was-exit.

The common theme I keep seeing is that the bwauths need to fix their
systems, but beyond that, or which part of their system, I don't know.

We still have a depressingly low number of relays that support IPv6

In short, you add:

[tor-relays] amount of unmeasured relays continuously rising since 2 weeks

2015-05-14 Thread nusenu
-BEGIN PGP SIGNED MESSAGE-
Hash: SHA512

Dear Tor BW Authories,

we'd like to bring the following issue to your attention.
Since the last two weeks the amount of unmeasured relays is steadily
rising [1].

unmeasured relays on 2015-05-01: 387
unmeasured relays today: 1087 (and growing)


Graph showing the last 5 months:
https://trac.torproject.org/projects/tor/attachment/ticket/13450/unmeasured_relaycount.png

Data:
https://trac.torproject.org/projects/tor/attachment/ticket/13450/2015-01-01__2015-05-13_unmeasured_count.csv


Would be great if you had some time to look into this:
https://trac.torproject.org/projects/tor/ticket/13450
(follow ups should probably go to trac)

..so bw doesn't go wasted. A contributed but unused relay doesn't make
relay ops happy.

thanks!

Re: [tor-relays] Tor Consensus Weight Stuck at 20 (Even on Relay with Stable Flag)

2015-05-14 Thread Speak Freely
A quick update regarding my guard-that-was-exit.

This relay, when it was an exit relay, never got past consensus weight
of 20. When I changed it to guard, the consensus weight immediately
jumped, and bandwidth was finally starting to be used. As usual, it
took a few days for full usage, but it did come.

Instead of measured bandwidth at 20b/s, it now read 45kb/s. Though arm
indicated the average speed was 7-11Mb/s.

A few hours ago I switched that relay back to exit, and so far
everything looks goodish. The measured bandwidth still says 45Kb/s.

I'm now averaging 10.6Mb/s, and have downloaded 16GB and uploaded 17GB
since my last email.

In arm, I lost my HSDir flag, but I have received Exit flag, and have
just over 500 exit connections and 1700 in/out connections.

The consensus weight, or anything for that matter, hasn't changed in
Atlas yet, but that's not terribly surprising. There were recent
changes in how/when Atlas report things now, right?


So... perhaps I just found a fix? Err... Workaround. This isn't a fix.

I'll take a look at doing this to the other relays to see if this
fixes the problem for them as well.

Maybe some other people can do the same thing to confirm?

1) Comment out your ExitPolicy accept rules
2) service tor restart
2) Run the relay as a middle/guard until you see in Atlas your
consensus weight rises - it should rise within a few hours, but seeing
as how your relay isn't working anyway - you can try to wait a day to
make sure all those bwauths pick you up.
3) Uncomment your ExitPolicy accept rules
4) service tor restart
5) Report your status back.



How exciting!

Matt

Hello nusenu,

Thanks for the kick.

For other statistics, each hour I copy over the votes that moria1 sees:
http://freehaven.net/~arma/moria1-v3-status-votes

And there's also
https://consensus-health.torproject.org/#bwauthstatus

It is clear that the bwauth scripts are buggy and need a rewrite. And
not just buggy -- I think their design is probably flawed too.

I know of several research groups who have been working on better
bandwidth estimation schemes, with the main goal of making them more
robust to cheating, but with the secondary goal of still being adequately
accurate.

I had been hoping that one of those would be ready by now, but the
research group I've been paying the most attention to has quite a bit
of work left to do before they have a cheating-resistance estimation
scheme that doesn't open up too many other problems.

Another hope we have is Aaron Gibson's upcoming OTF fellowship, which
focuses on improving the bwauth system. I think we'll have to find the
right balance there between a redesign, which would take a while but
could be better for us in the long run, and bugfixes on the current
system, which would help things in the short term but take time away
from the redesign.

I'll call Aaron's attention to this thread too and see if he can provide
some insights.
