Upgrade your 'tarragon' Tor relay?
by Roger Dingledine 06 Apr '20

06 Apr '20

Hi William, You are running a Tor relay, which is great: http://rougmnvswfsmd4dq.onion/rs.html#details/1D4AB6248E3D7DF9C4FBE40DCFAA3… First: that Tor version is obsolete, and because of old bugs, we will soon cut relays running those versions out of the network. Please consider upgrading! Second: let us know if there is any way to help you bump up the bandwidth that you are allocating to the Tor relay. :) You can find Tor packages for your distro / OS here: https://trac.torproject.org/projects/tor/wiki/TorRelayGuide#Platformspecifi… Ideally you will switch to keeping up with our stable releases, but if you need a stable that is especially stable, the Tor 0.3.5 branch will be maintained until Feb 2022: https://trac.torproject.org/projects/tor/wiki/org/teams/NetworkTeam/CoreTor… and you can see the lifetimes of other Tor versions on that table too. Let us know if we can do anything to make the process easier. And lastly, I am cc'ing the new network health mailing list (which has public archives), to help us stay synced: https://trac.torproject.org/projects/tor/wiki/org/teams/NetworkHealthTeam Thanks! --Roger

Your Tor bridge is running an obsolete version

Hi there, You seem to be running the following Tor bridge, which is great: 2B280B23E1107BB62ABFC40DDCC8824814F80A72 But that Tor version (0.2.9.16) is obsolete, and because of old bugs, we will soon cut bridges running those versions out of the network. Please consider upgrading! You can find Tor packages and instructions for your distro / OS here: <https://community.torproject.org/relay/setup/bridge/> Ideally you will switch to keeping up with our stable releases, but if you need a stable that is especially stable, the Tor 0.3.5 branch will be maintained until Feb 2022: <https://trac.torproject.org/projects/tor/wiki/org/teams/NetworkTeam/CoreTor…> and you can see the lifetimes of other Tor versions on that table too.

Tor Exit Failures
by [REDACTED] 19 Mar '20

19 Mar '20

hello >From time to time (about once a week for one day) the exit scanner of arthur edelstein[1] shows my windows exit[2] with a failure rate. I usually only see this happening when the "Average probability weighted failure rate" is high too so i wonder if his measuring is reliable or if it is not a problem on my side. If the failure rate is correct is there a way for me to find out why or when the failures are happening? Georg, you wrote that you are currently doing these tests too. Could you tell me the results of my relay? Thanks [1] https://arthuredelstein.net/exits/ [2] DC81AA3B1D51566DBF27BFA562E4047AEB1C52DA

anonduke is failing to relay exit traffic
by Georg Koppen 16 Mar '20

16 Mar '20

Hello! Your relay anonduke[1] seems to fail relaying exit traffic according to our measurements. We ran tests from different vantage points and it was not possible in 10/10 cases to reach https://example.com or https://eff.org. Could you please look into that and resolve the issue on your end? Some of our runs and results are available on Github.[2] Please let us know if you have further questions and when the problem is resolved on your side. Thanks for running a relay!

Exits and Tor's IPv4 /16 Path Restriction
by teor 16 Mar '20

16 Mar '20

Hi, I'm in contact with one of the exit operators in 185.220/16, which currently contains about 28% of the Tor networks exit capacity: https://metrics.torproject.org/rs.html#aggregate/as/185.220. They have asked me when that /16 will start causing path selection issues for tor clients. The guard and middle probabilities in that /16 are almost 0%, so I think the answer is: "Try not to put guards or middles in that /16." But I thought I'd also mention it here, because there might be wider network health issues I'm not aware of. (Since 0.3.5.1-alpha, Tor also checks the IPv6 /32 during path selection. 2 operators in that IPv4 /16 have separate IPv6 /32s, and the others don't have IPv6. So IPv4 is the stricter condition here.) T -- teor ----------------------------------------------------------------------
