Relay that's been running for a long time suddenly saying it's new?

Hi, So my relay at https://metrics.torproject.org/rs.html#details/79E3B585803DE805CCBC00C1EF36… is suddenly saying it's a new relay. Don't know why this would happen as it's been running for a few years, but suddenly saying it's new? Thanks. --Keifer

That is the funny thing, everything else was working fine. Only the Tor relays experienced connection problems.

They're much easier to > deal with during an attack. But don't quit. It'll pass. I'm still in the process of gaining experience but don't worry about me quitting, I consider this my new hobby. My servers are exclusively dedicated to this - so there is nothing important on them for me to lose. Also, I pride myself on running exclusively exit relays as this is what is apparently needed and thus it is where the challenge lies for me. Hi, I didn't see your original email and I don't currently have it in my inbox to reply to it directly but I can tell you by looking at your metrics history for "Alberta", indeed you had the same problem on Dec.18 that happened to my relays. The attackers seem to be picking a group of relays at a time and move on to others and it may be a while before they come back again. However the problem gets amplified if you're running an exit relay without having large enough resources to deal with all this traffic. I'm not running an exit relay, so I have to deal with the problem for a few hours, but all this outgoing traffic from my relay and other relays that are under attack will inevitably end up at exit relays. This means that even if they move on from my relay to another one, the traffic will still continue to poor into exit relays, so the duration of the attack for an exit relay may be much longer. This shouldn't stop you from bringing your rely back up. You're not doing anything wrong and there's nothing wrong with your set up. If you're running other services on the same server of course the heavy load might disrupt those services as well, which is why it's always a good idea to only run Tor on the server and not to mix it with other services. My suggestion for the time being, keep running my firewall scripts as they do help making the duration of the attack shorter by putting some of those IP addresses in the block list and help making it less painful and see how it goes. And in the long run, if you find that you don't have the resources or patience to deal with such heavy load, consider running a middle/Guard relay instead of an Exit. They're much easier to deal with during an attack. But don't quit. It'll pass. Cheers. On 1/15/2024 8:14 PM, denny.obreham(a)a-n-o-n-y-m-e.net wrote: > > Sorry, but I'm going to vent a little bit.

Did not know that about port 22. I used a variant of the ReducedExitPolicy which accepts port 22 according to https://gitlab.torproject.org/legacy/trac/-/wikis/doc/ReducedExitPolicy . > Did you check > https://gitlab.torproject.org/tpo/core/tor/-/issues/ for the bug you > reported? I wasn't even sure if it was a bug, if I did something wrong, or if it was related to my ISP; hence my question on the mailing list.

Sorry, but I'm going to vent a little bit. I'm not a network specialist, so 11 days ago I sent the following email to this mailing list asking for help because two of my Tor exit relays were completely frozen and I was unable to put them online again. Nobody answered, not even a comment. No wait, there was one person - very active on this mailing list recently - who sent me an email personally to tell me that I was an idiot (referring to what, I don't know) who should kill himself. Adding furthermore that if I didn't commit suicide within 72 hours, he would personally come to my house and kill me with a Glock 9 mm. Fun stuff, very disturbing. Anyway, no serious answers, someone calling me an idiot: I tried to look as best as I could at what I did wrong. Couldn't find anything. My only available solution was to rebuild completely my server, something I wanted to do for a while because of other undesired quirks that were bothering me with my setup. I knew it would take a long time - which I didn't really have - but I finally finished my new setup yesterday. (Don't look for 25FC41154DCB2CAE3ABD74A8DFCD5B90D2CFFD57 or the bridge, they have been shut down for the moment.) Today, I read a line from Chris Endiku-6 saying: "Thereâs something going on for a while and I havenât seen any mentions of it." The exact problem I mentioned! He says it goes "as early as Dec.23"; my problem goes to Dec 18 as shown in my previous email. Also, not mentioned in my previous email, before I renewed my setup, my tor-ddos firewall rules (I use the ones from Endiku-6) had blocked about 5 times more IP than usual - if that can be useful information to anyone. Sorry for the rent, I just needed to vent a little: There was something wrong, and I wasn't crazy or incompetent! I still would like to know how to restart such a relay, if this happens again in the future - other than reinstalling the entire server, that is. Thanks in advance.

Relay’s first seen date got reset
by Rafo (r4fo.com) 16 Jan '24

16 Jan '24

I run the following relay: https://metrics.torproject.org/rs.html#details/6C336E553CC7E0416EBC8577A728…. I just noticed that my relay’s ‘first seen’ date got reset. Tor now thinks that my relay is less than 2 weeks old. But when you open the 6 months graph, you can see the actual ‘first seen’ date which is November 29th 2023. Is it possible to fix this ‘first seen’ date back to the actual value?

Relay reboots every 15 minutes
by torserver 15 Jan '24

15 Jan '24

Starting about a week or so the number of connections raised rapidly to 18000+ and since then my middle relay reboots every 15 minutes. Lowering the relaybandwidth to a few MBytes partly solved these reboots. Before these unplanned reboots the relay has run for months at 20 - 40 MBytes traffic without issues. The number of connections now is around 11000 per relay. How can I prevent these reboots?

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

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

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

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