Hi, So for Debain 12, what is the command to install OBFS4? For my bridge at https://metrics.torproject.org/rs.html#details/0E547D99DEB753B20A19EEAA053C… Even though I configured obfs4 in torrc its saying no transport protocols. Thanks.

Solicitation for an IPv4 block
by Christopher Sheats 20 Nov '24

20 Nov '24

Hello everyone, In light of Tor Project's push into the global south, I'm bringing on a new advisory board member (https://freeradical.zone/@kedislav) from Chile, and together we're documenting co-location and IP transit costs in the country for a possible Tor exit relay deployment. However, in order to do this, we need some company/university/nonprofit, or some kind person, to donate to us a /24 (or greater) IPv4 block. If said entity is in the USA, it's possible to make this a tax-deductible donation since we are a 501(c)(3). If you could connect me to anyone who might be able to do this for Tor, please feel free to connect me over Signal or email. We can use our existing IPv6 block for dual-stack relays. Or we might get a new ASN and new IPv6 block for that region. If you have any information about Chilean co-location and/or IP transit deals, or contacts, or even good places to get used or new servers, please let me know. I'm hoping that our involvement in the region will help inspire others to do something similar. We'll of course do a full bi-lingual write up like we did in 2017 (https://emeraldonion.org/blog/starting-a-human-rights-isp/). -- Christopher Sheats Director, Emerald Onion Signal: +1 206.739.3390 // emerald.01 Web: https://emeraldonion.org Mastodon: https://digitalcourage.social/@EmeraldOnion

Journal warnings spam
by Dionysios K. 19 Nov '24

19 Nov '24

Hey guys, Do you have any solution to stop the spam caused by tor: The IPv4 ORPort address 127.0.0.1 does not match the descriptor address <IP>. If you have a static public IPv4 address, use 'Address <IPv4>' and 'OutboundBindAddress <IPv4>'. Indeed I have a static IP but behind nat, so defining it in torrc is not possible as it can't bind to it.

Re: Looking for a new provider? Try Wedos.
by George Hartley 15 Nov '24

15 Nov '24

First of all, sorry for the late re-post of this e-mail to the list. An individual also active on the tor-relays list messaged regarding a new provider, I recommended one which is not crowded with Tor nodes, but our fellow decided to lie about the provider. Please read their quote. I can still recommend Wedos.cz for Guards/Middle relays, as well as bridges, and if you have very restrictive exit policy, maybe also for exits - however, confirm with staff first, and let them know which ports you want to allow. Also, always reply to all non-automated abuse reports, and forward them to the address for processed abuse reports given to you by staff. This was my original reply: Because their AI chat bot has infinite intelligence right? I know 2 people working there personally, Michal Jakubec and Roman Mondek, and they both reassured me yesterday that Guard/Middle and Bridge are NOT a problem, as long as they stay Guard/Middle or Bridge nodes. Using Tor FROM their network is also no problem.. using Tor to access THEIR is no problem. But, I did not trust their word.. So I tried it myself: No problem accessing the website using around 10 different exit nodes.. Then, I tried to order: Again, no problem! Received bitcoin payment information using a Tor mail service within 10 minutes: This is where I stopped, I did not pay the invoice and e-mailed Wedos stafff to please remove the order. But, Wedos supports Tor, and is a great choice especially for Guards/Middle nodes as well as bridges. Please don't lie about providers.. alternatively, if they still don't support Tor for you, please show the symptoms you are encountering. -GH On Thursday, November 7th, 2024 at 5:11 PM, Red Oaive clearly(a)ivegotyour.pw wrote: > On 2024-11-05 16:32, George Hartley via tor-relays wrote: > > > Also, please consider using a provider that is not overcrowded with > > Tor nodes already like OVH. > > > > I can recommend Wedos.cz ... https://wedos.cz/en/ > > They block access to their web site to Tor users.

Update: Tor relays source IPs spoofed to mass-scan port 22
by gus 12 Nov '24

12 Nov '24

Hello everyone, I'm writing to share that the origin of the spoofed packets has been identified and successfully shut down today, thanks to the assistance from Andrew Morris at GreyNoise and anonymous contributors. I want to give special thanks to the members of our community who have dedicated their time and efforts to track down the perpetrators of this attack. Although this fake abuse incident had minimal impact on the network -- temporarily taking only a few relays offline -- it has been a frustrating issue for many relay operators. However, I want to reassure everyone that this disruption had no effect on Tor users whatsoever. We're incredibly fortunate to have such a skilled and committed group of relay operators standing with Tor. Thank you all for your resilience, ongoing support and for making the Tor network possible by running relays. Gus -- The Tor Project Community Team Lead

Hi, So wondering for running a middle relay on a raspberry pi esque micro computer, what are the recommed maximum bandwidth for running a middle relay on a hole network (by a stock isp router, etc?)? Thanks. --Keifer

Tor relays source IPs spoofed to mass-scan port 22?
by Pierre Bourdon 10 Nov '24

10 Nov '24

Hi relay ops, A few hours ago I received a forwarded abuse report from Hetzner for one of my machines running a Tor relay (not exit). Some random ISP was claiming I was sending SSH connections to them, and at first I couldn't find any corroborating evidence in my own network logs and I was ready to dismiss it. But then I noticed that there is in fact something weird: all 4 of my machines running Tor relays are seeing *return* TCP traffic (RSTs or SYN-ACKs) from port 22 from various machines all over the world, at a very low rate. Kind of like someone spoofing source IPs to send SYNs everywhere. I can't figure out at all whether that's actually what's happening and what the intent would be though. Some tcpdumps showing random RSTs coming back to my machines running relays (with no traffic being initiated by said machines beforehand): 04:19:14.705034 IP 198.30.233.69.22 > 172.105.199.155.39998: Flags [R.], seq 0, ack 171173954, win 0, length 0 04:20:15.135733 IP 124.198.33.196.22 > 172.105.199.155.23506: Flags [R.], seq 0, ack 1985822135, win 0, length 0 04:21:30.222739 IP 223.29.149.158.22 > 172.105.199.155.27507: Flags [R.], seq 0, ack 3614869158, win 0, length 0 04:14:25.286063 IP 45.187.212.68.22 > 195.201.9.37.59639: Flags [R.], seq 0, ack 41396686, win 0, length 0 04:14:25.291455 IP 107.152.7.33.22 > 195.201.9.37.39793: Flags [R.], seq 0, ack 1391844539, win 0, length 0 04:14:25.322255 IP 107.91.78.158.22 > 195.201.9.37.48900: Flags [R.], seq 0, ack 1434896088, win 65535, length 0 04:12:39.470366 IP 121.150.242.252.22 > 77.109.152.87.57627: Flags [R.], seq 0, ack 2452733863, win 0, length 0 04:13:05.549920 IP 46.188.201.102.22 > 77.109.152.87.9999: Flags [R.], seq 0, ack 3253922544, win 0, length 0 04:14:33.027326 IP 1.1.195.62.22 > 77.109.152.87.52448: Flags [R.], seq 0, ack 351972505, win 0, length 0 By any chance, any other relay ops seeing the same thing, or am I just going crazy? (it does kind of sound insane...) Any speculation as to the reason for this? Best, -- Pierre Bourdon <delroth(a)gmail.com> Software Engineer @ Zürich, Switzerland https://delroth.net/
