Relay not connecting

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!

[14254 similar message(s) suppressed in last 180 seconds] ``` There are a few more of these messages appearing afterward (My bandwidth is unlimited). 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.

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.

Remove my relay from relay search on Tor Metrics
by nemeto 27 Dec '23

27 Dec '23

Hi, I set up a middle relay at first, but I changed my mind to run a bridge to avoid blacklisting of my public IP by certain websites. Is it possible to immediately remove my relay from relay search on Tor Metrics? If not, when will my relay be removed from the relay list? Thanks! Nemeto

Reboot torservers.net @ 37C3
by Stefan Leibfarth 25 Dec '23

25 Dec '23

Hello everyone, torservers.net has been inactive for quite some time. I have organized a meeting at the 37C3 to change this in the future, if you want to. You are a representative of a non-profit who is running Tor relays and you think it could be useful to a have some kind of umbrella association? Please attend this meeting. When: 30.12.2024 0:00 Where: Saal D Link: https://events.ccc.de/congress/2023/hub/de/event/torserversnet-meeting/ If you are not @ 37C3 but you'd like to work on a future for torservers.net, please contact me via mail. All the best Leibi

Tor Relay Operators Meetup @ 37C3
by Stefan Leibfarth 25 Dec '23

25 Dec '23

Hello everyone, there will be a Tor Relay Operators Meetup @ 37C3: https://events.ccc.de/congress/2023/hub/de/event/tor-relay-operators-meetup/ As always, TROMs are open for everyone (if you have a 37C3 ticket of course) who is running a relay, wants to run a relay or just thinks about it. :-) At this point we don't have a agenda, but everyone is free to bring up questions or topics at the meeting itself. Please share with your friends, social media and other mailing lists! See you there Leibi

Relay data limit
by Dan 22 Dec '23

22 Dec '23

Hi all, I've been running a middle relay on a VPS for about 2 months now. The provider limits the monthly data transferred to 5TB but does not charge for over-usage. Instead, the bandwidth is throttled to 1Mb/s after the limit is reached until the 1st of the next month. I currently have AccountingMax set to 2.5 TB (since it's the max in each direction) and AccountingStart set to "month 1 00:00". Generally that 5TB limit is hit between the 15th and 17th of the month, causing the relay to go dormant until the 1st. What I'm wondering is: 1 - Is it better for the network if the relay is active 24/7, even if sometimes it's much slower? 2 - Will it negatively affect my relay's reputation if sometimes it's very slow? Thank you -- Dan

Dutch Relays
by Christopher Sheats 19 Dec '23

19 Dec '23

Hello, Emerald Onion is looking for co-location and IP transit opportunities in the Netherlands for deploying new exit relays. We have our own ASN, v4 and v6 IP space. Priorities are: - Free or cheap transit - Free or cheap cross-connects - Free or cheap colo - Amsterdam Internet Exchange - Netherlands Internet Exchange Working with collectives, or starting a new one, is interesting too. Please share your thoughts! -- yawnbox https://disobey.net/@yawnbox https://digitalcourage.social/@EmeraldOnion

Declining Relay Usage
by likogan 18 Dec '23

18 Dec '23

My exit relay has seen steadily decreasing traffic from 8MBps to 6MBps over the span of three weeks. It averages a load of ~50% CPU usage and ~65% RAM usage. It's rated network capacity is 17Mbps on a 10GB link. Why would traffic decrease if I have plenty of spare resources? Are there ways I can configure my server to boost traffic? <https://metrics.torproject.org/rs.html#details/292FCACE773DC259B799914A23BE…>

If you mean that HardwareAccel is needed, I would still disagee. If I'm not mistaken the AES-NI support is implemented in OpenSSL not via an "engine" that you have to "use", it is just built-in internally on some deeper level. For a proof you can run "openssl engine" in the console of any AES-supporting machine, and you will not see any loadable engines there, aside from rdrand, which is unrelated, and "dynamic" which just means it can load some acceleration engines if it had any. And for instance VIA Padlock would show up as "padlock" in that list. Please use reply to all the mailing list. Sorry for bringing out your mail into the public, but it didn't seem to be strictly private in any case. -- With respect, Roman

Hi, will there be a Tor relay operators meetup @37C3 [*]? Also, there were apparently no meetups in November and December this year? Kind regards telekobold [*] https://events.ccc.de/congress/2023/infos/startpage.html
