Help - My relay consensus has been stripped back to 20
by Sebastian Urbach 03 Jan '15

Hi, Found the snippet with the changes for the guards: Tor Weekly News, 30th of July 2014 Once directory authorities have upgraded, they will “assign the Guard flag to the fastest 25% of the network”. Some experiments showed that “for the current network, this results in about 1100 guards, down from 2500.” -- Sincerely yours / Sincères salutations Sebastian Urbach ----------------------------------------- Definition of Tor: 10% luck, 20% skill, 15% concentrated power of will, 5% pleasure, 50% pain and 100% reason to remember the name! -----------------------------------------

Help - My relay consensus has been stripped back to 20
by bigbudtor＠Safe-mail.net 03 Jan '15

03 Jan '15

On the 29th December one of our relays, bigbud (6911888F83565892FE23F1B03EB501D80E1E8780) which had a consensus of 630+ and had been running for nearly 18 months (100 days uptime running 2.5.8) suddenly started receiving much less traffic. I have seen a gradual reduction in traffic over the course of the last year but on the 29th the drop off was very significant and I saw in Atlas that the consensus is dropped to 20. When I look at the consensus files it shows that bigbud has a consensus of 20 and that Unmeasured was set to 1. Any ideas please? I upgraded Tor to 2.5.10 after I noticed the consensus drop. Is this something to do with the Lizard new relay flood or something or is there an actual problem with the relay? On a related note the relay lost guard status too a few months ago and I couldn't see why that would be.

Not sure if related, but I noticed today one of my exit relays was not operating properly. Turned out the bind server was not resolving properly. I turned off dnssec and it started working again...

RPM upgrade issue.
by Sascha Siekmann 01 Jan '15

Hello, Happy New Year, everone! I've been chasing this down here for the last hour or so and I thought I might as well share it since others might also experience it. I am running https://atlas.torproject.org/#search/plutonium After running yum update this lead to a different fingerprint being generated for the same host. Nov 29 01:09:27 Installed: tor-0.2.5.10-tor.2.rh6_5.i686 Dec 29 19:21:07 Installed: torsocks-2.0.0-2.el6.i686 Dec 29 19:21:10 Updated: tor-0.2.5.10-1.el6.i686 Then, traffic collapsed by going down from <> 8MB/sec to pretty much nothing. I checked the logs and found permission errors. The group for Tor was changed from _tor to toranon, so the permissions were wrong after the rpm was installed. Also, /etc/tor/torrc had this line commented : ## The directory for keeping all the keys/etc. By default, we store ## things in $HOME/.tor on Unix, and in Application Data\tor on Windows. DataDirectory /var/lib/tor So it was defaulting to ~tor directory, tor/tor.log-20141230:Dec 30 03:13:01.000 [warn] Default DataDirectory is "~/.tor". This expands to "/.tor", which is probably not what you want.

Some thoughts on the security of crowdsourced computing: Installing additional software increases the attack surface of your relay, even more so when the new software access the network. (Not to mention any additional libraries.) There is also the issue of the security of automatic updates to the any executables - Folding@home may have less of an issue with this than BOINC, as there is only one project involved. If you're willing to accept the additional risk, it seems like a worthy cause. (There's also a minor additional power cost, which really only impacts your provider and the environment…) > Date: Sat, 27 Dec 2014 12:54:24 +0100 > From: mikael <mikael(a)gutanet.sk> > > Hi, > some years ago I contributed to https://secure.worldcommunitygrid.org/ > via BOINC (https://boinc.berkeley.edu/) but stoped. > Forgive my paranoia, but I couldn't find proof that it really helps what > they write, that the provided cpu power could doesn't land at NSA for > example :/ > > Any different experience? > >> On 12/26/14 6:55 PM, Sebastian Urbach wrote: >> Dear list members, >> >> I would like to invite any operator, who has some idle Cores (CPU or >> GPU) left,to join the folding@home distributed computing project: >> >> http://folding.stanford.edu/ >> >> There is now a brandnew team called Tor Project (Unofficial) with the >> id 227615.
