Tor relay operator research
by Ana Custura 14 Jan '24

14 Jan '24

Dear operators, I'm conducting a study to understand relay operator motivations and needs, funded by OTF. If you had about 30-45 minutes to talk (completely anonymously if you wish) about your experience as a relay operator, it will really help this research, especially if you're running a relay in non-western country. If interested please reach out to me either on acute(a)torproject.org or ana(a)sr2.uk. Cheers Ana

OrNetStats Update Interval
by nusenu 14 Jan '24

14 Jan '24

Hi, OrNetStats, https://nusenu.github.io/OrNetStats/ a website for relay operators and other interested parties, showing various stats about the tor network used to update its stats on a daily basis and recently switched to ~weekly updates while still maintaining a daily granularity. If you have any expectations or opinion on how often the stats should be updated on OrNetStats please let me know. Off-list replies are fine as well. kind regards, nusenu -- https://nusenu.github.io

[To the maintainers of Tor Metrics] Metrics showing erroneous data for my two relays, can somebody responsible please take a look at the issue?
by George Hartley 11 Jan '24

11 Jan '24

Hello, for about 3 months I have been hosting two Tor relays: https://metrics.torproject.org/rs.html#details/AF42E6C77196A37F041A1A1E953E… https://metrics.torproject.org/rs.html#details/7F7D1A5BE88FA7C9358955705AE7… After doing system maintenance (mainly upgrading packages), slightly adjusting my "BandwidthRate" and "BandwidthBurst" for both relays and then rebooting the server earlier, the guard relay now shows the following on Metrics, even though the graphs still show the old, correct data: > The first time that this relay was seen in the consensus: 2024-01-10 16:00:00 (8 hours 57 minutes and 21 seconds) This is even though metrics shows an uptime of almost 16 hours?! The fingerprints did not change according to both the metrics page, and the Tor log. I did not delete or mess with each relays DataDirectory or the secret keys. I have a MyFamily setting in both relays configs: > MyFamily $AF42E6C77196A37F041A1A1E953E51B4656BDC1B, $7F7D1A5BE88FA7C9358955705AE7AFA61EEDA2B0 Yet the relays don't show up as being in a family, and Metrics doesn't at all display the other relay counterpart as a family member when visiting the page for the guard or exit. There is also no line in the relays journal (from journalctl -u tor@guard) indicating that the guard relay is new to the network, and it retains its older flags. This only seems to affect my guard relay, the exit metrics page shows mostly valid data, except for the missing family member. Since I did not change anything that would cause this, this is likely a bug with the metrics page, and I would encourage you to look into it. Thank you very much, George

Re: [tor-relays] Remove my relay from relay search on Tor Metrics

I think it's after 30 days it gets automatically removed.

Relay not connecting
by denny.obreham＠a-n-o-n-y-m-e.net 06 Jan '24

06 Jan '24

I manage the two following exit relays: * https://metrics.torproject.org/rs.html#details/25FC41154DCB2CAE3ABD74A8DFCD… * https://metrics.torproject.org/rs.html#details/3B85067588C3F017D5CCF7D8F65B… They are both on the same IP and servers. A few hours ago they lost contact even though I have both Apache and I2P servers on the same machine that are reachable. The weird log messages seem to go back to Dec 18, after a restart: ``` Dec 18 07:49:47 a-n-o-n-y-m-e Tor-Alberta[904715]: Bootstrapped 100% (done): Done Dec 18 07:54:18 a-n-o-n-y-m-e Tor-Alberta[904715]: Your computer is too slow to handle this many circuit creation requests!

This is the typical Heartbeat that comes afterward: ``` Dec 18 13:49:42 a-n-o-n-y-m-e Tor-Alberta[904715]: Heartbeat: Tor's uptime is 6:00 hours, with 476 circuits open.

Relaxed timeout for circuit 527 (a Measuring circuit timeout 3-hop circuit in state doing handshakes with channel state open) to 60000ms. However, it appears the circuit has timed out anyway. ``` I have stopped both relays until I figure out what is going on. Help would be appreciated.
