Some questions about the uptime requirement
by David Hu 05 Jan '22

05 Jan '22

Hello Tor Relay operators, I am hosting a rather new Tor relay and my uptime is only about 13 hours, while I would like to contribute to Tor by continuing as a relay (NOT an exit one though because of frequent abuse of exit relays and my ISP won't allow it). My question is that I am going to another location for vacation for 3 days and my relay would probably not be up during that time. Does that forfeit my chance to be chosen by clients forever? Thank you! Regards, David

TOR Metrics showing relay as down but logs show it is apparently active
by Tor Geheimschreiber 05 Jan '22

05 Jan '22

Not sure if this is the correct list on which to ask but a new node created just over 7 days ago is now being shown on Tor Metrics (atlas.torproject.org) as being down. However local logs show heartbeat activity and some directory activity. A port scan of the IP address shows: -- cut here Starting Nmap 7.80 ( https://nmap.org ) at 2022-01-05 14:22 GMT Nmap scan report for [redacted] Host is up (0.018s latency).

Maybe the next step in russian Tor discrimination
by Tor Relays 03 Jan '22

03 Jan '22

Hello, i have a relay at profitserver.ru at their Chelyabinsk location and recently the relay fell out of the consensus. I can ping all authorities with IPv4 and IPv6 and torproject.org is not blocked. I opened the ControlPort and tried to manually create circuits to the authorities. extendcircuit 0 authoritynickname getinfo circuit-status I observed that i can successfully create circuits to no more than three authorities and it seems to change to which authorities i can create circuits. The unsuccessful circuits stay in EXTENDED but never reach BUILT until Tor gives up eventually. Currently no other of my russian relays are affected. I am not an expert with the ControlPort but i hope this is proving what i tried to prove. Here is the conversation with the support: me: Hello, I am running a (non-exit) Tor relay on the VPS and it stopped working a few weeks ago. I can ping the Tor authorities IP addresses but when i try to manually create a Tor circuit it seems to timeout 6 out of 9 times which indicates some blocking attempts on your (or your upstream providers) side. I have a couple of other Tor relays in russia and i have never seen routinely failing manually created circuits to the Tor authorities. Do you block Tor or do you otherwise mess with Tor traffic? support agent: Hello, i can't say something about TOR network, now. We have black box from government, which can control traffic, and perhaps block TOR. Ourselves don't block TOR me: Thanks for your answer. The TSPU from Roskomnadzor that is doing Deep Packet Inspection? I feel with you and all the russian citizens... :( Good luck support agent: Maybe it's a black box If this is indeed their blackbox messing with Tor traffic then it is quite subtile because it does not block torproject.org and pings to the authorities are going through. The relay suddenly was online for one consensus in the last weeks and i can still use it when i manually set it as a Guard in my Tor client. So if you run a relay in russia and you experience weird stuff with it then you may not only want to check if you can reach the authorities by ping but you may want to try to manually craft a circuit to all of them. Hope that helps anyone Cheers

[Censorship in Russia] More of my bridges got blocked
by spaceoddity＠disroot.org 29 Dec '21

29 Dec '21

Hello Tor people, just me chipping in about recent event. Today, I discovered that somewhere around Dec, 22, all three of my recently launched bridges have been censored on at least one network (MegaFon Moscow AS25159). Metrics show a drastic traffic drop in the range of Dec, 21-23 for all three bridges. Investigating further, I discovered (using tcptraceroute/nc) that all three hosts started responding with RSTs to all of their open ports (not only bridge ports but SSH and other recently opened ports too). NATd source IP address was unchanged from my usual one in every case. One of the bridges had distribution method set to HTTPS, and the other two were distributed via Moat. All ran recent Tor 0.4.6.8 Docker image. NB: One of the bridges has incorrect 'First seen' date on the metrics portal - it displays '2021-12-25' despite being launched several days prior. To summarize: 1. Bridge blocking happens via the common 'fast RST' method 2. It happened relatively quickly (all bridges are less than 10 days uptime by now). 3. Somehow, all three of my recently launched bridges were blacklisted despite using different ASs/hosters/countries for each. Is it a coincidence, or it's because Moat prefers to hand out newer bridges first, or due to something else entirely? Also, I can not rule out that some step in my distribution chain was compromised -- I gave out these bridges privately to a few friends. -- Best regards, Space Oddity.

Incorrect "first seen" info
by a tor op 28 Dec '21

28 Dec '21

I notice that the "first seen" info on my obfs4 bridge status page on tor atlas / metrics all of a sudden is incorrect, by years. Not sure if it's something that introduced itself with latest update or what. The various graphs on traffic and users are still correct through. A tor op

[Censorship in Russia] Make HTTPS/Moat captcha more complex?
by spaceoddity＠disroot.org 27 Dec '21

27 Dec '21

Hi there. I was thinking, what could be the ways Russian authorities could get bridges to block. One of the obvious ways to do this is to grab bridges from Moat/HTTPS, but since that would require solving a captcha, this would indicate its strength is insufficient, or they are able to crowdsource/mass solve somehow. The other thought is an attack via email. Can we do something with it, what do you think? -- Best regards, Space Oddity.

Hello again. I'm found it weird that all resources says that "Distribution mechanism" should change after a few days and mine was still "none". So now I'm trying torix's suggestion and deleted the keys and all the /var/lib/tor/ directory, changed nickname and started it again. The hashed fingerprint for my bridge is now: 3B5D1AE581EE4113610E094D5993D6299E64EDEF Its the same torrc file I shared before, just new nickname.
