write-history for exit relays only?
by Philipp Winter 06 Sep '16

06 Sep '16

I want to learn how many bytes exit relays forwarded. I assume that the write-history that is published in a relay's extra-info document includes bytes that were relayed as part of the exit's guard and middle role? If so, is there a way to learn how many bytes were written by the relay in its exit role only? I suspect that one could approximate this number by accounting for the probability of all exits being selected as guard, middle, and exit, but I would prefer a simpler and more reliable approach.

Tor bridge and obfs4proxy
by Arisbe 05 Sep '16

05 Sep '16

I need someone's bridge experience. I had an HD crash and lost one of my Tor bridges. So, I'm rebuilding on a leased VPS. First I tried with Debian 8 and then with ubuntu 16.04 when Debian didn't work. With both operating systems I get a warning message when I start Tor. Tor is the latest version as is obfs4proxy: Sep 04 13:39:41.641 [warn] Strange ServerTransportPlugin type 'obfs4' Sep 04 13:39:41.641 [warn] Failed to parse/validate config: Invalid server transport line. See logs for details. There are no log entries. Apparently Tor starts without the proxy. I have configured torrc as follows: ServerTransportPlugin obfs3 obfs4 exec /usr/bin/obfs4proxy ExtORPort auto /usr/bin/ does contain the obfs4proxy file. Does anyone know my problem? Is there a 'tell-all' explanation of obfs4proxy? Thanks, Arisbe

Useful metrics for relay operators
by Alison 05 Sep '16

05 Sep '16

Hello all, After Roger's recent checkin emails to this list, some of the folks from the community and metrics teams have started to brainstorm ways that we could use Onionoo data [1] to give better support and recognition to the relay operators. For example, a weekly mail of all the relays that just passed the "earned a tshirt" threshold, or some other threshold about how much bandwidth they've pushed over a period of time. The community team would then contact the operator(s) and congratulate them, thank them for their service, see if we can offer them help in any other ways, and so forth. I'd like to hear directly from relay operators about what kinds of metrics they might like to see involved in a project like this. Have you achieved milestones with your relays that you wished Tor Project would have given you some recognition for? Have there been specific times you'd wished for a checkin email, like the one Roger sent (eg 3 months after starting a new relay)? Anything else that you think Onionoo could measure that would be valuable for you as an operator? Thank you so much for running relays! Looking forward to hearing from you. Alison [1] https://onionoo.torproject.org/

Guard vs Exit Bandwidth
by Tristan 05 Sep '16

05 Sep '16

Looking at the advertised bandwidth vs bandwidth history from Tor Metrics[1], it appears that guard relays see much more traffic than exit relays. I think it might be partially because guard-only, guard-middle and guard-exits aren't separated, but would it really skew the numbers that much?

BeagleBoard-X15
by jchase 04 Sep '16

Hello, At least a year ago someone recommended the BeagleBoard-X15 as a Tor relay, partly due to its speed. The X15 does not seem to be available in the Netherlands (according to Mouser electronics). Are there any other comparable boards available in the Netherlands? Thanks, James Chase

total relay bandwidth
by jensm1 03 Sep '16

03 Sep '16

Hi, (rather new relay operator here, so excuse me, if this is a dumb question) I just saw this (https://metrics.torproject.org/bandwidth.html) graph, which shows that the advertised relay bandwidth in the whole network is more than double the actually used bandwidth. While it's certainly nice to have a bit of breathing space to absorb load spikes, I'm wondering, if new relays (i.e. non-exits) are actually helpful at this point, or if they simply don't make a difference. Am I missing something obvious? Thanks, Jens

What are the thoughts of relay operators on this? https://ghostbin.com/paste/kmnzz I can be persuaded otherwise, and perhaps i'm being naive, but i believe that operation of the network should remain independent from the politics within the organization. mk

Wrong mode on /var/run/tor
by Alexander Dietrich 31 Aug '16

31 Aug '16

Hello, I just had a tor instance exit with these error messages: [warn] Failed to parse/validate config: Failed to bind one of the listener ports. [err] Reading config failed--see warnings above. For usage, try -h. [warn] Restart failed (config error?). Exiting. Above that, the log contains an endless stream of these errors: [warn] Permissions on directory /var/run/tor are too permissive. [warn] Before Tor can create a control socket in "/var/run/tor/control", the directory "/var/run/tor" needs to exist, and to be accessible only by the user and group account that is running Tor. (On some Unix systems, anybody who can list a socket can connect to it, so Tor is being careful.) When I checked, the /var/run/tor directory had the mode "rwxr-sr-x". After removing the permissions for "other", tor started without problems. Did anyone else see this? I'm using Ubuntu packages from the deb.torproject.org repository.

new relay package for Ubuntu 16.04+
by Chad MILLER 31 Aug '16

31 Aug '16

tl;dr: $ sudo apt install snapd; sudo snap install tor-middle-relay Hi. Ubuntu has been working on a new kind of software package* that aims for isolation from the rest of the system, so 1) anyone can create packages for others without review, 2) security is better, and 3) it can be the basis for lots of supposedly single-purpose systems like cars, watches, home security systems, etc. The packages work for desktop and server too. The upshot is that soon, they hope, many devices will run the miniature Ubuntu plus the single package that makes the device do what it does to act like that device. If the mfr doesn't restrict it, we users can add other things that they never intended to make our device do more. Your Wifi Router could also be your print server. Why not? I made a tor-middle-relay package, so the TVs, Wifi Routers, Toasters, Self-driving Cars, Phones... of the world that are running that new kind of Ubuntu (or other OS that implements this package system!) can also help the Tor network. The code that enables that new package system is already in Ubuntu 16.04 LTS, so even existing desktops and servers can already use it. So, if you use Ubuntu 16.04 LTS, this should get you a Tor relay $ sudo apt install snapd $ sudo snap install tor-middle-relay (The ARMHF architecture has an open bug where the new package security rejects the "personality" syscall that Tor calls, so ARMHF doesn't work out of the box right now.) Once you have it installed, try $ sudo /snap/bin/tor-middle-relay.configure to bump up your bandwidth limit over the conservative defaults. There are a few dozen users already. https://atlas.torproject.org/#search/UbuntuCore I'd be happy to have an explosion of devices all over the world. Please send bug-reports privately, not to this list. - chad * https://developer.ubuntu.com/en/snappy/ http://snapcraft.io/ -- Chad Miller chad.org c2c3 0e6c a4ce d49e 79cf 06c61 a806 deac 3042 0066

Re: [tor-relays] Cheapest HW to get 20Mbit?
by Joel Cretan 29 Aug '16

29 Aug '16

Having run a relay on an older RPi with standard Raspbian, I would caution you to look carefully at the packages you're using, if you choose that hardware. Of course the Tor package itself is woefully out of date, so you have to build from source. But it's worse than that. I noticed that running regular apt-get update && apt-get upgrade was not enough to keep openssl up to date. Over a year after Heartbleed had been fixed, I noticed that my "up-to-date" version was still vulnerable, not to mention all the other bugs discovered there in the last few years. I thought maybe I could replace openssl with one of the forks, but was unable to find any pre-built packages or even signed source distributions with signing keys distributed over TLS. It was a pretty bad state of affairs, so I shut that relay down entirely. Maybe it has improved since then, but be careful.

Closing a relay, to move/upgrade, identity question ?
by Petrusko 29 Aug '16

Hey, Planning to close, then re-build a relay. (1st time I'm testing it on the whole system!) Some useful informations here about : https://www.torproject.org/docs/faq.html.en#UpgradeOrMove I think it's useful to stay on the same "identity"... But if the new torrc will use others TCP ports, will it be a mess ? No problem for me if this (new) relay will not have the same identity has before. But it will be nice to retore Atlas old graphs ;) If I'm paranoiac, and if this current relay has been corrupted, I think it's better to start a clean identity without the old keys ?

tor 0.2.8.x: in 26 days to the top

~26 days after the first stable tor 0.2.8.x release, it has become the most prevalent tor version on the network by consensus weight [1].
