Why is Cloudflare displayed when I do a speed test?
by templeos＠skiff.com 19 Jan '24

19 Jan '24

A blog post I discovered brought up that when they perform a speed test through Tor browser, Cloudflare is quite frequently displayed as the local host. I had the same result. Is there a reason for this, like perhaps the exit relay is proxied through Cloudflare? You can easily replicate this yourself by going to speedtest.net in Tor Browser.

A new kind of attack?
by Chris Enkidu-6 19 Jan '24

19 Jan '24

I've noticed a new kind of possible attack on some of my relays, as early as Dec.23 which causes huge spikes of outbound traffic that eventually maxes out RAM and crashes Tor. The newest one today lasted for 5 hours switching between two of the three relays on the same IP. During the attack, Tor becomes so busy processing the traffic that it becomes unresponsive to new connections for minutes at a time and effectively becomes a zombie exclusively processing the attacker's traffic until it eventually crashes and restarts. The interesting part is that when Tor restarts, it doesn't start from scratch building new circuits but it starts right from where it left out and keeps processing the previous connections. I have tried shutting down Tor for over 5 minutes and within one minute of restart, The RAM maxes out and the outbound traffic reaches the previous heights. This has been happening, not to all relays but to a select group of relays at a time and unless you're monitoring your Tor port from outside, you may not notice it's unresponsive. Another way to see if it's happening to you too is to check your monthly history on the metrics page and look for spikes of written bytes or sudden decrease of read bytes where you see a big gap between the two. I have included charts and excerpts from the log in my post in Tor forum at below link: https://forum.torproject.org/t/new-kind-of-attack/11122 I'd appreciate your insights and comments. Thank you.

Relay in Japan being marked as a US relay?
by Jag Talon 18 Jan '24

18 Jan '24

Hello, I have a relay in Japan with the IP of 198.13.48.219, but it's being marked as being in the US. I've tried using different websites like www.iplocation.net, iplocation.io, and www.wolframalpha.com and they're all telling me that the IP is in Japan. I'm wondering if perhaps there's an issue with the GeoIP lookup? Or perhaps an outdated database? Thanks! -- Jag Talon Designer for the Tor Project

PSA: Tor 0.4.7 reaches end of life (EOL) on 2024-01-31
by Georg Koppen 17 Jan '24

17 Jan '24

Hello! In case it affects you as you are still running your relay or bridge on Tor 0.4.7.x: the 0.4.7 series is going EOL on *2024-01-31* (roughly in 2 weeks from now). That's currently still 1346 relays, which means roughly 15% of the advertised bandwidth of the network (and 964 bridges, which means roughly 45% of the advertised bridges bandwidth). Please make sure you have upgraded to the 0.4.8.x series by then. Supported releases in general can be found on the network team wiki.[1] Thanks, Georg [1] https://gitlab.torproject.org/tpo/core/team/-/wikis/NetworkTeam/CoreTorRele…

Relay that's been running for a long time suddenly saying it's new?
by Keifer Bly 17 Jan '24

17 Jan '24

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.

I manage the two following exit relays: * https://metrics.torproject.org/rs.html#details/25FC41154DCB2CAE3ABD7 4A8DFCD5B90D2CFFD57 * https://metrics.torproject.org/rs.html#details/3B85067588C3F017D5CCF 7D8F65B5881B7D4C97C 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!

Last messages after the server reboot are: ``` Jan 6 08:34:17 a-n-o-n-y-m-e Tor-Nestor[998]: Bootstrapped 100% (done): Done Jan 6 08:35:21 a-n-o-n-y-m-e Tor-Nestor[998]: Performing bandwidth self-test...done.

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.

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?
