IPv6 not showing up on tor exit node
by pimpnet 10 Jun '21

I run a tor exit node and have properly configured IPv6 but sometimes it does not appear on the tor relay list. This is fixed when I reboot the tor service but what could be the reason?

More Tor measurements next week [opt out]
by Zachary Newman 07 Jun '21

07 Jun '21

tl;dr: Low-load measurements coming; no action needed unless you would like to opt out. Hi all, Next week (week of 2021-05-31), we will be starting a wide-scale measurement of the latencies between relays on the Tor network for a research project; these measurements will last an estimated 1-2 months. We have the permission of the Tor Research Safety Board and this information will ultimately be used to improve the network. Further, the load at any one time on the Tor network from these measurements will be limited and negligible (approximately the same load as the start-up tests of a few new Tor clients). We are coordinating with the currently-running speed test[1], and will start our measurements after the conclusion of this speed test. If you operate a relay and would like to opt out of these measurements, please send us an email (shortor(a)csail.mit.edu) including the fingerprint of your relay(s). We will stop sending you traffic and, if the test has begun, delete past measurements involving your relay(s). Status updates will be posted publicly[2], and we will bump this thread before we start and if anything important changes. Please contact shortor(a)csail.mit.edu with any questions. Regards, Zack Newman (on behalf of the ShorTor team) [1] https://lists.torproject.org/pipermail/tor-relays/2021-May/019649.html [2] https://people.csail.mit.edu/zjn/tor.txt

New Test for Measuring the Accuracy of Tor Relays' Advertised Bandwidths
by Georg Koppen 07 Jun '21

07 Jun '21

Hello everyone! Some of you might remember the speed test Rob had been running during August 2019 to investigate the accuracy of the advertised bandwidth a relay is reporting in its server descriptor.[1] Back then this involved, for each relay, downloading several large data streams for a period of about 20 seconds to get a better estimation of the relay's true capacity (See: [1] and follow-up emails for the exact details of the experiment). We plan to do this speed test again in about 1 week and relay operators can opt-out of it (again) if they want to. We still believe that the overhead of this speed test is in line with regular usage, but if anyone doesn't want to participate that's fine. Let us know if so (by replying to this thread or off-list, if preferred) and we remove your relay(s) from the list to scan. Thanks, Georg [1] https://lists.torproject.org/pipermail/tor-relays/2019-July/017535.htmlff.

current HSDir flag requirements
by Scott Bennett 03 Jun '21

03 Jun '21

What are all the current requirements for a relay to get a HSDir flag? 96 (97?) hours of uptime and what else? Can someone tell me what my relay, MYCROFTsOtherChild, is missing for a HSDir flag? Thanks in advance for any relevant information. Scott Bennett, Comm.
