Request for Tor to support armhf architecture
by Landon 30 Aug '24

30 Aug '24

I am running a Raspberry Pi Raspbian OS (debian) mini computer. Tor software does not support this hardware without me having to compile it myself for my platform. Which I don't know how to do. My specific APT error message says this: N: Skipping acquire of configured file 'main/binary-armhf/Packages' as repository 'https://deb.torproject.org/torproject.org bookworm InRelease' doesn't support architecture 'armhf' The Raspberry Pi is a perfect computer to run Tor because it has 8 GB RAM, is tiny, only uses a max of 25 watts of power and works great as a network server. Plus, I don't have to leave my big power hungry desktop computer on all the time to run Tor. Raspberry Pi info page: https://www.raspberrypi.com/products/raspberry-pi-5/ Landon

a couple noob questions
by observatory123 27 Aug '24

27 Aug '24

Dear fellow relay operators, I've been hosting a tor relay on a VPS (strato) for a couple days now. I've never done this before, so I have a couple of questions: - Is it normal for my relay to only use up only about 2 MB/s after nearly 5 days of uptime despite bandwidth speed tests done with speedtest-cli generally reporting significantly higher bandwidth? - Is it normal for my relay to advertise 7.37 MiB/s on its relay search page despite bandwidth speed tests done with speedtest-cli generally reporting significantly higher bandwidth? - Do I have to mark somewhere that I'm hosting the tor relay on a VPS (which means technically a company also has control over the relay)? - Is this mailing list a good place to ask these questions? Or am I reaching too many people by doing this? When I say I performed a bandwidth test, I mean I performed a bandwidth test with the speedtest-cli debian package. The test generally tells me I have about 217 MB/s download speed and 113 MB/s upload speed. The nickname of my relay is observatory123 and its fingerprint is: 45431BF8AB66C673942C1E344BB520625CE5F817 Kind regards, observatory123

Hi, don't worry, a relay will be removed from metrics 7 days after you shut it down.

DMARC helps prevent Tor-exit from being abused for email SPAM.
by boldsuck 20 Aug '24

20 Aug '24

Hi @all, I thought DMARC was unimportant for a small domain, but I played around with it a few days ago. There are some DMARC monitor sites that you can use for free & I was surprised when I saw that in 2-3 days about 1500 emails were sent via my exit subdomains. Then I set DKIM and SPF to strict adkim=s; aspf=s; and DMARC subdomain policy to reject sp=reject; Since then, emails about Tor-exits have dropped to 0 ;-) -- ╰_╯ Ciao Marco! Debian GNU/Linux It's free software and it gives you freedom!

DDOS alerts from my provider
by Rafo (r4fo.com) 20 Aug '24

20 Aug '24

Hi,I have been running a relay for a few months now without any problems. But this week I’ve received 2 DDoS alerts from my provider (Netcup), both are ~3 gigabits. They seem to be coming from other Tor relays.I’m running an Invidious like instance on my server (which uses around 600 megabits) but I have a 2.5 gigabit port. So I configured my Tor relay to use 300-400 megabits.I’m not sure where that 3 gigabit of data comes from.I have lowered my advertised bandwidth to 100 megabits, would that be enough to prevent these kind of issues?Kind regards,Rafo

An Internet backbone blocklisted my Tor server!
by Landon 20 Aug '24

20 Aug '24

TL;DR... Write down your Tor server's GATEWAY IP address. if your server goes offline, try tracerouting to your Tor server's gateway IP address as well as your Tor server's IP address! You might be surprised by what you see! And also install MTR... It is helpful!! Here's the detailed explanation on how you can perform MTR command on your computer and server https://support.gcore.com/hc/en-us/articles/19864311353105-How-to-run-MTR-o… Okay, here is what happened... Late last night I tried to log into my VPS where I am running my Tor bridge server. I was unable to connect. It seemed like my server was offline so I filed a ticket with my service provider which is GCore Labs ( https://hosting.gcorelabs.com/ ) (I've been running my Tor bridge on their server for 4 years.) However, I discovered that my server was not actually down. I was able to login to my server using VNC in the control panel. I did some network diagnostics to diagnose my network connectivity problem. Even though my server was running, it was essentially offline. I could not ping or traceroute from my server to 8.8.8.8 or 1.1.1.1. It looked like there was a network outage. I used some looking glass servers to see what was going on as well. Here was what I discovered... From the Internet, I could ping and traceroute my VPS server's gateway (which is one hop away from my server) but if I tried to ping or traceroute using my server's actual IP address then this is where it stopped working. The culprit was Cogent Communications' routers! [AS174] As soon as packets destined for my server's IP address reached Cogent's routers, they were dropped!! However, packets destined for my server's gateway went through! >From what I understand, my server's gateway is the physical machine running my VPS. How can a packet reach my server's gateway, but not reach my server? It's not like the packet was not making it from my gateway to my server. The packets were being dropped at the edge of Cogent's network [AS174]. I also ran a traceroute on Cogents own looking glass server ( https://cogentco.com/en/looking-glass ) and when I used my server's IP, it showed nothing but when I used my gateway IP it worked! Tell me how that is possible if Cogent was not blocking my server's IP address? I sent Cogent an email asking why they were blocking my server's IP address in their routers. By the time they got back to me, my server was back online and was not being blocked. They sent me an email saying that packets going to my server were routing through their network, which by that time they were. What is so interesting about my Tor server that a major network backbone blocks my IP? If you look at my Tor server's usage graphs, you can see where it is periodically offline. Look at the 6 month graph for the average number of connected clients and you will see places where it is not online. https://metrics.torproject.org/rs.html#details/4A0B065DB3CF807C6910DFEF6D9C… I bet the reason that my server periodically goes offline is because it is being blocked and not because it is actually offline! Have you ever had this happen to your server? Landon

Re: [tor-relays] [tor-dev] Fwd: Introducing & Discussing "Reflec-Tor"s as concept | Exit-Relay as Entry-Relay | Tor & Echo | Adding Entry-Relays as Reflec-Tor to Exit-Nodes
by George Hartley 19 Aug '24

Hello, > Similar to Briar, even developers of such clients above tell the loss of messages and low reliability of the hidden to hidden path. Some of you might know, that there were use cases with missing messages in a range of 35-45 %. Sorry, but this is just not the case from my experience - it may take a while to fetch the descriptor of the hidden service, but once a TCP connection is established, aka. the ACK packet has been received, there should be no problems with packet-loss, this is one of the core features of TCP: Retransmission on various conditions. I also hosted a hidden IRC server, as well as a Tor hidden service on my grandmothers laptop, to be able to SSH in through Tor and troubleshoot problems. Experienced no packet loss, unless a relay in the circuit suddenly went offline. If you want, I can measure packet loss from various locations (Northern Europe, East Europe, and New York, USA). Also, to improve latency and throughput, you could make the server a one hop hidden server by enabling: > HiddenServiceSingleHopMode This way the looking up the server is faster, but clients remain anonymous using a normal 3-hop circuit. I don't think we need extra code for this, you could just build your app using the programming language of your desire and use the existing network. That's what I was doing with my ~200 user IRC server, and it worked fine, even while being hosted at home at a limited uplink of 15 Mbps, which now got upgraded to 30 Mbps. Unfortunately fiber is not an option, so we have to rely on 60+ years old copper wires maintained by Telecom, I have a quite fancy industrial router with modem software and capabilities, and we still use VDSL2 17a G.Vector (ITU G.993.5). I do however own a virtual machine machine on my friends colocated server at DataWagon, they are very exit friendly, zero abuse so far, I believe they just redirect abuse mails to /dev/null or something.. lol. Anyway, point is that I never encountered packet loss, and even if, the protocol would compensate for it. This became kind of a rant while I'm at work, so if it's not that useful, Im sorry.
