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. Cheers. -----Original Message----- From: tor-relays <tor-relays-bounces(a)lists.torproject.org> On Behalf Of teor Sent: Monday, January 28, 2019 10:24 PM To: tor-relays(a)lists.torproject.org Subject: Re: [tor-relays] Having Trouble With Speed Of OBFS4 Bridge On January 29, 2019 3:45:55 AM UTC, Keifer Bly <keifer.bly(a)gmail.com> wrote: >Thanks.

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!

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

Shutdown of fallback directory mirror armbrust: E781F4EC69671B3F1864AE2753E0890351506329
by Michael Armbruster 27 Jan '19

27 Jan '19

Dear tor-relay list, After a long time maintaining an exit relay that was also chosen to be a fallback directory mirror, I decided that the time has come to shut the relay down. It has only financial reasons (being a cheap server, but still using money out of my own pocket) and I will stay a happy user of Tor and, of course, will provide a new relay as soon as my financial situation gets better. How should we proceed and how long should I still let the fallback mirror run in order to gracefully migrate the fallback status away from my server? I do not want to disappear immediately without any further notice, so I wanted to ask how to further proceed. Kind regards, Michael Armbruster
