High processor usage - just curious
by Gary Smith 08 Feb '18

08 Feb '18

Hi, I have noticed that after a few minutes of becoming online, and randomly perhaps a couple of times every hour (??) tor uses 100 % processor on all cores for about 40/50 seconds. I am curious what is tor doing internally to need so much power? There is normally isn't more than 4 mbits going through my relay, I noticed this a while back on htop before the December load increase and on previous versions so this has got to be an "internal thing". There is no log entry when this happens. I do not think it is a bug I am just curious why it needs this much computational power, Thanks.

Exit Relay Up
by Conrad Rockenhaus 05 Feb '18

05 Feb '18

Hello All, I just brought up my third relay, ConradsOVHRelay03, as an exit. I appreciate the feedback that everyone provided me with before and I hope that this relay is configured perfectly. I’m glad to add more bandwidth to the cause. Thanks, Conrad

by nusenu 05 Feb '18

05 Feb '18

Hi, relayor v0.3.1 has been released. https://github.com/nusenu/ansible-relayor Whether you run a single or many relays, relayor helps you with running relays with minimal effort (automate everything). Introduction to get you started: https://medium.com/@nusenu/deploying-tor-relays-with-ansible-6612593fa34d Main benefits for a tor relay operator ====================================== * automation - no more manual setup tasks * security: offline Ed25519 master keys every tor instance is run with a distinct user * automatically makes use of IPv6 IPs (if available) * automatic tor instance generation (two by default - configurable) * enables tor's Sandbox feature by default on Debian-based systems * easily choose between alpha/non-alpha releases * easily restore a relay setup * easily choose between exit relay/non-exit relay mode * automatic deployment of a tor exit notice html page via tor's DirPort * automatic MyFamily management Supported Operating Systems ---------------------------- Debian 8, 9 and Debian Testing OpenBSD 6.2 FreeBSD 10.4, 11.1 HardenedBSD 11.1 Ubuntu 16.04 CentOS 7 Fedora 27 Changes since v0.3.0: ------------------------------ - support custom tor-exit-notice.html files (fixes #140) - increase tor_alpha_version: 0.3.2.x -> 0.3.3.x - Debian/Ubuntu: add support for tor nightly builds - implement per-instance ExitRelay settings (fixes #146) - make tor package state configurable (latest vs. present) regards, nusenu -- https://mastodon.social/@nusenu twitter: @nusenu_

Relays not in cached consensus
by Tyler Durden 05 Feb '18

05 Feb '18

Hi Just ~3 weeks before the 34C3, two of our newer Exits were thrown out of the consensus weight and since than never came back in. I'm talking about: geri (geri.enn.lu) 93FAB6F91C2EF33D0ACEEF7448177FCA2CEB99A0 freki (freki.enn.lu) C8AB1B2AF0CBAAE3611A814B4C7D38DCE0CBFEB4 We tried to purge the Tor installation, generate completely new keys, switched to alpha versions, switched back to stable, waited for weeks but it's always the same result. Only the authority servers moria1, longc. and dizum seem to "recognise" our exits. The logs say the same for every authority server except the 3 ones mentioned above: [info] handle_response_fetch_desc(): Received http status code 404 ("Servers unavailable") from server '154.35.175.225:80' while fetching "/tor/server/d/[__redacted__] I'll try again soon. Any ideas how to fix this? Greetings -- Frënn vun der Ënn A.S.B.L. (NGO) e. virii(a)enn.lu (GPG: 0xce8c12f32a2cf11b) t. +352-27-40-20-30-4 w. https://enn.lu/

nyx question on info on top right side, present on CentOS, missing on Debian.
by Stijn Jonker 04 Feb '18

04 Feb '18

Hi All, I initially went to the nyx website to find the right forum to ask questions. I understood this is the one :-), if not apologies. So I'm running two relays, one is running on CentOS7, the other Debian Stretch. On both I have nyx (2.0.4) installed. The "Debian" one is missing the CPU, Exit policy etc info. It's not tor version specific, as I recently upgraded the tor software on the nodes regularly. So on the CentOS node I see this on the top at the right; cpu: 61.3% tor, 5.0% nyx mem: 371 MB (12.4%) pid: 1279 uptime: 02:59:09 fingerprint: 328E54981C6DDD7D89B89E418724A4A7881E3192 exit policy: reject *:* On the Debian node it's simply not printing any of these three lines. I can't find in the (debug) logging whether an utility or library is missing. It's nothing major, but annoying. Especially with the new alpha releases it's nice to keep an eye out on mem/cpu. Does anyone have an idea what the trick is to get it to work on debian? -- CentOS info: [user@tornode ~]$ tor --version Tor version 0.3.3.1-alpha (git-de8bc9eed6eaadfc).

tor cpu / MBit/s benchmarks
by tor7 04 Feb '18

04 Feb '18

Hello! I'd like to collect some samples for how many MBit/s on a single tor daemon are possible on given CPU model before it is limited by the CPU. If your single tor daemon routes more than 350 MBit/s in each direction and you are running on bare metal it would be awesome if you could share your - CPU model (ideally a link to ark.intel.com if it is an intel cpu) - avg. daily CPU usage (ie. from munin graphs) - actual traffic (MBit/s) - optional: relay fingerprint thank you! tor7
