Hardware specs for a high-bandwidth Tor exit?
by Christian Pietsch 08 Jul '20

08 Jul '20

Dear Tor friends, the NGO I am volunteering for (Digitalcourage e.V.) has been running modest Tor exits for many years. Now we finally have the opportunity to run a high-bandwidth exit relay because we found a data center with a nice internet connection (20 Gbit/s) we may use. My question is: What kind of hardware should we buy to utilize this bandwith? I am told that we need an SFP+ networking card to connect to the fibre optics cable, but what CPU and mainboard would you recommend nowadays? It should fit into a 1 height unit 19" enclosure. If you prefer to tell me in person: I will attend the Tor meetup in Brussels on Friday <https://blog.torproject.org/events/tor-meetup-brussels> and the subsequent Freedom Not Fear event <https://www.freedomnotfear.org/>.

Stable and fast flags
by David Strappazon 04 Dec '19

04 Dec '19

Hi, How long is it supposed to take to get the stable and fast flags? My bridge is up since 13 days. At the beginning I had both flags then I lost them because of a reboot I think. Since, they never came back. Envoyé depuis ProtonMail mobile

In the nyx log you see messages like 'In the last X hours we have seen X unique clients' (I don't remember the exact wording) Those are the clients that did use your bridge. > When I connect to it, all I see in nyx are OUTBOUND connections and > not even one inbound connection (maybe that’s by design in order to > protect connecting users' privacy, I don’t know). You are probably right. In the past you could see connecting users in nyx as inbound connections without visible IP-address. Now they are not displayed as inbound connections any more. The outbound connections that are needed for these users are still displayed.

Probabilities
by Vitor Milagres 03 Dec '19

03 Dec '19

What do guard, middle and exit probabilities mean? Say, for example, that the middle probability for a certain relay is 0.15% and the guard probability for the same relay is 0.20%. What does that mean? Thanks

Version 0.3 of obfs4 bridge docker image released
by Philipp Winter 27 Nov '19

27 Nov '19

We recently released version 0.3 of our obfs4 bridge docker image. To upgrade to the new image or deploy a new container from scratch, please take a look at our instructions: <https://community.torproject.org/relay/setup/bridge/docker/> Here's what changed in our new version: * We added a new script, 'get-bridge-line', which prints your bridge line. Run it as follows: docker exec CONTAINER_ID get-bridge-line * We improved our setup instructions. As part of this, we added a Makefile that facilitates the process of deploying a container. Here are the new instructions: <https://community.torproject.org/relay/setup/bridge/docker/> * Our new Makefile uses docker volumes to persistently store tor's data directory. This means that you can now upgrade to future docker images (which involves deleting your existing container) while keeping your bridge's identity. * We made tor log to stdout in addition to its log file, so the following command now shows tor's entire log output, and not just the first few lines. docker logs $CONTAINER_ID * The bridge can now bind to obfs4 ports < 1024. * One can now run multiple bridge containers on a single machine. Thanks to thymbahutymba for providing a great template for our Makefile and for suggesting docker volumes. Cheers, Philipp

MyFamily line commented out but stays valid?
by Michael Gerstacker 26 Nov '19

26 Nov '19

Hi, when i comment out the MyFamily line with an # in the torrc on one relay it seems to be still handled like before. Hitting x in nyx or waiting a few days or rebooting does not make any change. Is this expected? I expected that relay to show as part of no family now and listed as "Alleged Family Member" on all other relays which still list that fingerprint in their torrc.

switching ISP and Fallback listing
by René Ladan 24 Nov '19

24 Nov '19

Hi, I might switch my ISP soon-ish from XS4ALL to Freedom Internet so my relay [1] will get a new AS number and IPv4/IPv6 address, how does this impact being listed as a fallback candidate? I'm currently not selected as a fallback. (And yes, I know about fallback needing to be long-term reliable, but this event was caused by the big corporate powers :( ) Thanks, René [1] https://metrics.torproject.org/rs.html#details/4E8CE6F5651E7342C1E7E5ED031E…

bridge relay search is "wrong"
by David Strappazon 23 Nov '19

23 Nov '19

Hi, My bridge appears down when checking "tor relay search" on smartphone and up when checking the site from a laptop. Is there a reason? does someone already had the same issue? Sent with [ProtonMail](https://protonmail.com) Secure Email.

Newbie question about bridge
by David Strappazon 22 Nov '19

22 Nov '19

Hi, all I configure a bridge on October the 31th. On the first days I had to reboot it multiple times but few days later I had all the necessary flags, fast and stable include. Now I'm at 9+ days of uptime, I lost the fast and stable flags and the advertised bandwidth is at 792 KiB/s when my bandwidth is configured at 3 MB/s with burst at 6 MB. Of course I haven't seen a single client. My question is: is it normal and part of a relay/bridge lifecycle or is there something wrong? Ps: on metrics.torproject.org, everything is fine. Nothing wrong in my logs either and I can use it when configuring my it in a tor browser. Any opinions or advices would be welcome. David. Envoyé depuis ProtonMail mobile
