Questions to ask exit node providers
by F67 Group 08 Oct '19

08 Oct '19

We are thinking of running a Tor Exit Node. Does anybody have a list of questions to ask before purchasing a VPS or colocation? I came up with some basic questions: - Do you allow a Tor exit node? [with explanation] - What are the policies for handling abuse complaints? - How much uplink bandwidth do you provide? Any other questions one should ask? Thanks.

Relay without OpenSSL
by Alexander Nasonov 30 Mar '19

30 Mar '19

I recently tried updating one of my relays to Tor 0.4.0.1 compiled with NSS (and without OpenSSL) but it failed to start, see the logs below. I wonder if this configuration is supported at all and whether I should try running a brand new relay instead of updating?

note to Falback Directory operators: bandwidth wasting bot
by starlight.2018q2＠binnacle.cx 03 Feb '19

03 Feb '19

For the last year a bot of some kind has loaded Fallback Directory relays with excessive directory document requests. Some detail can be found in ticket #27921 at https://trac.torproject.org/projects/tor/ticket/27921. To determine if your relay is affected, look the relay up in https://metrics.torproject.org/rs.html, click the 6-Month history tab, and examine the graph for significantly higher "write bytes per second" relative to "read bytes per second". I find this annoying (since I pay for the wasted bandwidth) and came up with a one-line hack that mitigates the abuse without impairing the usefulness of the DIR service to normal relays and clients. If you compile your daemon from source and are interested contact me directly for the patch.

Circuit storms
by Felix 31 Jan '19

31 Jan '19

Hi everybody Circuit storms observed of up to 100k and 250k per relay for over hours. Consumed BW rises by about 10%. Number of stateful server connections is higher. Using Tor 356 to 401. Anybody else observes that? Switching to some paranoid server settings for some days :) -- Cheers, Felix

Installing Tor As Windows Service And Updating Via Script (was RE: Having Trouble With Speed Of OBFS4 Bridge)
by Keifer Bly 30 Jan '19

30 Jan '19

Darn, I just restarted the relay because tor 0.3.5.7 came out today before seeing this email. I have been playing with the Windows Powershell regarding this and made some interesting discoveries. So, I found that the Windows Powershell equivalent to linux's "apt-get" is "install-package -Name". And so, I tried running "install-package -name tor" and got this error (see the attached screenshot). The error is that tor project is not in the list for Windows to install packages from on Windows (it's not finding tor packages as a result), as I discovered at the other attached image. However, according to my research at https://docs.microsoft.com/en-us/powershell/module/packagemanagement/regist… Windows Powershell can register sources to install packages from via Register-PackageSource -Name command listed. So Something along the lines of PS C:\> Register-PackageSource -Name "tor" -Location "http://torurl" -ProviderName "TorProject" may have interesting results possibly. What is the tor packages download url so I may try this? Once this is returned to me I will return to the list with my findings.

Hmm, I thought someone answered this question already, but I can't find the answer in the list archives. 0.3.4.8 is still a supported version. You don't need to update. One simple way to keep Tor up to date on Windows is to use the Chocolatey package manager to install the tor package: https://chocolatey.org/packages/tor It has Tor 0.3.3.9, which is still a recommended version. You can script chocolately using the "choco" command. Otherwise, you can script powershell to download and install packages. I can't help you with the details, because I don't do a lot of work on Windows. But maybe someone else on the list can. If you work out how to do it, please write back to the list with the scripts you used.

IRC relay operator meetups
by Colin Childs 29 Jan '19

29 Jan '19

Hi everyone, The IRC Tor relay operator meetups are beginning again! To get started, we are going to be holding these meetups once per month. The meetups will be held the first Thursday of the month, at 2:00UTC. This means the February meetup will be held next week, on the 7th. To allow us to use meetbot for recording the meetup, we will be holding them in #tor-meeting. On the first Monday of the month, I will send out a reminder email with the date and time, along with a pad that people can add discussion topics to. For February, the reminder email will go out on the 4th. I look forward to seeing everyone there!

Hetzner - "no.spam@example.com" relays

Hi, to the operator of the relays listed bellow. You care currently not setting the MyFamily option on your relays, which puts tor users at risk. Please configure your relays with MyFamily to avoid getting your relays rejected. more information: https://medium.com/@nusenu/some-tor-relays-you-might-want-to-avoid-5901597a… https://trac.torproject.org/projects/tor/wiki/doc/ReportingBadRelays#Whatis… 2019-01-28 | Up | Ext | JoinTime | Nickname | Version | IP | AS | CC | ORp | Dirp | OS | Contact | eFamMembers | FP | |------+-------+------------+---------------------+-----------+----------------+---------------------+------+-------+--------+-------+---------------------+---------------+------------------------------------------| | 0 | 0 | 01:34:19 | somerelay | 0.3.3.7 | 116.203.57.161 | Hetzner Online GmbH | de | 9001 | 9030 | Linux | no.spam(a)example.com | 1 | 24C3BC672621D6FCB7923DE031738B23EE0C1819 | | 0 | 0 | 01:48:53 | somerelay | 0.3.3.7 | 116.203.57.161 | Hetzner Online GmbH | de | 9001 | 9030 | Linux | no.spam(a)example.com | 1 | CBDCA8B16E2D4111A6618BAB3F114C358B8E35DB | | 1 | 0 | 05:00:50 | somerelay1IHcuer9Cn | 0.3.3.7 | 116.203.57.161 | Hetzner Online GmbH | de | 9001 | 9030 | Linux | no.spam(a)example.com | 1 | CA307A53194D6DE8B033226C541654117AFCF5F2 | | 1 | 0 | 02:54:44 | somerelayId8wPoBbRJ | 0.3.3.7 | 116.203.57.160 | Hetzner Online GmbH | de | 9001 | 9030 | Linux | no.spam(a)example.com | 1 | F9578C192A76062C2B49F938A53291AA5CE3CFBF | | 1 | 0 | 02:54:49 | somerelayT7WbYRznBW | 0.3.3.7 | 116.203.59.81 | Hetzner Online GmbH | de | 9001 | 9030 | Linux | no.spam(a)example.com | 1 | CFDF026F3FC52BF347A395A1224D70D9ACBEF9C5 | | 1 | 0 | 02:55:45 | somerelayung2AiqzXu | 0.3.3.7 | 116.203.66.45 | Hetzner Online GmbH | de | 9001 | 9030 | Linux | no.spam(a)example.com | 1 | 97F47C07A3DEA4C1A885C2C15008592635DA54B6 | | 1 | 0 | 02:54:46 | somerelayvpoDStFnGZ | 0.3.3.7 | 94.130.184.189 | Hetzner Online GmbH | de | 9001 | 9030 | Linux | no.spam(a)example.com | 1 | 5CD0F83B59229F86419757FE54CFF6EE859EA0ED | https://nusenu.github.io/OrNetRadar/2019/01/28/a7 -- https://twitter.com/nusenu_ https://mastodon.social/@nusenu

Having Trouble With Speed Of OBFS4 Bridge
by Keifer Bly 29 Jan '19

29 Jan '19

Hello, So my OBFS4 bridge at https://metrics.torproject.org/rs.html#details/148BD64BED9F2C27637D986DE032E CF14E5B9E9A seems to be having some speed issues, only reaching about 40-50 kb/s of speed. This is strange, as it should be much faster than this. My thoughts on why this is happening: Where I living, am probably nowhere near the bridge authorities for one. I am running an obfuscated bridge (which as this requires an additional process to be running alongside the tor process, could this be a part of it?) I am running off of the only internet provider available in my area (Charter / Spectrum) which is an isp that uses cable structure so maybe they have some kind of limitation in place? My router is a Netgear Orbi router which should be able to handle up to 60,000 connections at once so there should be no issue there. Any help is appreciated, thank you. --Keifer

diff-cache OOM
by notatorserver 28 Jan '19

28 Jan '19

I am running tor 4.0.1-alpha inside a docker container with a memory limit (6GB). Tor runs out of memory and aborts or crashes periodically. Usually I see an error message like this: Could not mmap file "/var/lib/tor/data/diff-cache/1149": Out of memory ...(repeated some number of times) followed by segfault Sometimes I see a message: Out of memory on malloc(). Dying followed by abort. Am I correct to assume the diff-cache is the issue here? Looking at the files it seems they are all pretty small (~500K). Is some badly behaved client requesting 12,000 of these diffs causing my relay to mmap them all at once? or is it just expensive to generate and generating 30-60 at once is enough to use all the memory? Are there any config options to reject expensive queries or otherwise limit concurrency? Thanks
