New subject: Troubleshooting rasptor4273 (was: Decline in relays)

24 Oct 2017

      My IP/ORPORT is 24.132.17.230:9001.

My relay is still running. arm shows traffic going through and several
circuits on the connections page. And from my notices.log file:
Oct 24 16:35:45.000 [notice] Heartbeat: It seems like we are not in the
cached consensus.
Oct 24 16:35:45.000 [notice] Heartbeat: Tor's uptime is 6 days 0:00 hours,
with 2 circuits open. I've sent 47.17 MB and received 237.75 MB.
Oct 24 16:35:45.000 [notice] Average packaged cell fullness: 66.463%
Oct 24 16:35:45.000 [notice] TLS write overhead: 8%
Oct 24 16:35:45.000 [notice] Circuit handshake stats since last time: 0/0
TAP, 0/0 NTor.

However there's also a lot of this in that file:
Oct 24 16:55:45.000 [warn] Your server (24.132.17.230:9001) has not managed
to confirm that its ORPort is reachable. Please check your firewalls,
ports, address, /etc/hosts file, etc.
Oct 24 16:55:45.000 [warn] Your server (24.132.17.230:9030) has not managed
to confirm that its DirPort is reachable. Please check your firewalls,
ports, address, /etc/hosts file, etc.

I added the log line to my torrc and sent a SIGHUP signal. Entries are
being added to the log file, so that worked.

Regards,
Joep

Interesting. And it is still running as of now without any problems? Can you
give me the IP/ORPORT tuple?

You think you can add this to your torrc and then HUP your relay (very
importatnt to NOT restart it).

    Log info file <FULL_PATH_TO_LOG_FILE>

And then after a some hours (maybe a day), we'll be looking for "Decided to
publish new relay descriptor".

If it appears, we know that your relay keeps uploading to the directory
authorities so thus chances are that there is a problem on the dirauth side
not finding you reachable.

Thanks!

Alias: rasptor4273
Am running Tor 0.2.5.14 on Debian, Raspberry Pi 2B. I upgraded to that
version on September 3rd.
I grepped through these:
https://collector.torproject.org/archive/relay-descriptors/consensuses/
and
the latest entry I found for my alias is in the file
./17/2017-09-17-13-00-00-consensus.
Not sure what other information I can provide. Do let me know if I can do
anything else to help troubleshoot.
Best,
Joep

Hello everyone!
Since July 2017, there has been a steady decline in relays from ~7k to
now
~6.5k. This is a bit unusual that is we don't see often such a steady
behavior
of relays going offline (at least that I can remember...).
It could certainly be something normal here. However, we shouldn't
rule
out a
bug in tor as well. The steadyness of the decline makes me a bit more
worried
than usual.
You can see the decline has started around July 2017:
https://metrics.torproject.org/networksize.html?start=
2017-06-01&end=2017-10-23
What happened around July in terms of tor release:
2017-06-08 09:35:17 -0400 802d30d9b7  (tag: tor-0.3.0.8)
2017-06-08 09:47:44 -0400 e14006a545  (tag: tor-0.2.5.14)
2017-06-08 09:47:58 -0400 aa89500225  (tag: tor-0.2.9.11)
2017-06-08 09:55:28 -0400 f833164576  (tag: tor-0.2.4.29)
2017-06-08 09:55:58 -0400 21a9e5371d  (tag: tor-0.2.6.12)
2017-06-08 09:56:15 -0400 3db01d3b56  (tag: tor-0.2.7.8)
2017-06-08 09:58:36 -0400 64ac28ef5d  (tag: tor-0.2.8.14)
2017-06-08 10:15:41 -0400 dc47d936d4  (tag: tor-0.3.1.3-alpha)

...
2017-08-01 11:33:36 -0400 83389502ee  (tag: tor-0.3.1.5-alpha)
2017-08-02 11:50:57 -0400 c33db290a9  (tag: tor-0.3.0.10)
Note that on August 1st 2017, 0.2.4, 0.2.6 and 0.2.7 went end of life.
That being said, I don't have an easy way to list which relays went
offline
during the decline (since July basically) to see if a common pattern
emerges.
So few things. First, if anyone on this list noticed that their relay
went off
the consensus while still having tor running, it is a good time to
inform this
thread :).
Second, anyone could have an idea of what possibly is going on that is
have
one or more theories. Even better, if you have some tooling to try to
list
which relays went offline, that would be _awesome_.
Third, knowing what was the state of packaging in
Debian/Redhat/Ubuntu/...
around July could be useful. What if a package in distro X is broken
and
the
update have been killing the relays? Or something like that...
Last, looking at the dirauth would be a good idea. Basically, when did
the
majority switched to 030 and then 031. Starting in July, what was the
state of
the dirauth version?
Any help is very welcome! Again, this decline could be from natural
cause but
for now I just don't want to rule out an issue in tor or packaging.
(Replying to OP since it went OT)
As some of you know, TDP did a little suite of shell scripts based on
OONI data to look at diversity statistics:
https://torbsd.github.io/oostats.html
With the source here for further tinkering:
https://github.com/torbsd/tdp-onion-stats/
Maybe something we could look at is "exception reports", which in some
industries means regular reports that look at anomalies or "exceptions"
which display out-of-the-ordinary statistics, generally prompting some
sort of action.
In other words, daily reports would be run on, say, bw consensus by
country, and if there was some statistically significant change over N
periods of time, it would be noted. Or if a particular OS drops or
jumps. Or if a particular AS jumps or declines for relays, bridges,
whatever.
If done right, a bunch of these reports could point to particular
changes to the network that need further investigation, and in some
cases, might quickly point to the related issue.  Eg, countryX shutdown
ISP with a particular AS number, etc.
The more reports coupled with careful optimization over time could
become an alarm system for Tor network changes, instead of just "er,
such-and-such distro didnt update their packages then, I just found out
in git."
Thoughts?
