Cheapest HW to get 20Mbit?
by Daniel Armyr 28 Aug '16

28 Aug '16

Hi Since a few months back I have two RPi running Tor relays and delivering about 1Mbit each of peak throughput. Now my ISP has increased my max upload speed and I am looking to contribute more, somewhere in the 20Mbit range or possibly more. But what hardware do I need? Has anyone written down a list of minimum requirements to get a certain throughout? I have tried to google, but failed. Sincerely Daniel Armyr.

Hi Daniel, Judging from my pi3 mid relay where 5mbit traffic is about 20% of 1 core (tor uses 1 core mostly) 20-25mbit should be fine for pi3. In the peak hours it will be probably close to maximum what pi3 is capable on 1 core but when cost is a factor I would not think of anything else 1gb ram is more than enough, my tor uses about 150mb If you think of exit, cpu load may be higher

The regular bandwidth cap holds traffic back for a time, then the burst bandwidth cap lets some through at a higher speed for a short period. -J

GeoIP
by Fred Rauch 27 Aug '16

27 Aug '16

Hi, I just started up another relay, and atlas' GeoIP data on it is incorrect (says it is in Netherlands when it is in fact in Lithuania). Where does Atlas get its GeoIP data from? Can this be corrected? It's not a huge issue but it would be nice for the correct country to be displayed. albino

Some information about Tor relays
by Liu, Zhuotao 26 Aug '16

26 Aug '16

Hi Folks, This is Sky from University of Illinois. Currently we are working on research project related with Tor. To help us to better design and evaluation our proposal, we need some information about the Tor relays that is currently unavailable from the Atlas. Thus, if someone who operates Tor relays could provide us such information, your help will be greatly appreciated. :) We hope to have an estimate about computation capacity of Tor relays. For instance, how many circuits a relay can maintain when its CPU is driven to about 100%? On average, how many circuits are maintained by a busy guard and what the CPU utilization is. These kinds of information would be really helpful. Further, in Sep 2013, Tor saw a spike in its clients. https://blog.torproject.org/blog/how-to-handle-millions-new-tor-clients The suspicion is that a botnet used Tor as its C&C channel. Is there any data about the relay utilization during that time? For instance, how many more circuits a relay had to maintain during that time? Thanks a lot for your help. :)

BSD buildbot: call for enrollment
by George 24 Aug '16

24 Aug '16

There is a BSD-focused buildbot at https://buildbot.pixelminers.net/ for admins running *BSD relays: FreeBSD, NetBSD, OpenBSD. . . The buildbot is a useful tool for Tor developers working on development versions of Tor. The BSDs are particularly important for a variety of reasons, including addressing portability issues with Tor code. Certainly the operating system monoculture problems with the Tor network shouldn't need any comments at this point (ie RFC5961). For those interested in enlisting their BSD relay, this TDP blog post provides more information: https://torbsd.github.io/blog.html#buildbot http://bptfp7py2wclht26.onion/blog.html#buildbot g -- 5F77 765E 40D6 5340 A0F5 3401 4997 FF11 A86F 44E2

Tor not running since last Debian update
by Martin Kepplinger 24 Aug '16

24 Aug '16

Hi So I think 2 days ago I updated tor on my debian stable machine and since then it's seen as not running anymore. It should be a relay. And locally it doesn't listen on port 9050, so it's not even a client now. My torrc hasn't changed. What's going on? Any config changes I missed? thanks martin

Sorry to bother you guys again Its 6am here and after reading the FAQ and other install guides I am out of ideas I just complied TOR (hurray!) on a NON-ROOT server. 1. Issue: I cant find the torrc file. I found out that the rest of the stuff is in ~./tor but no torrc at all. Where is it/should I put it? 2. Issue: I only need the complied TOR executable and I can safely delete all the other stuff? Cheers, Markus
