ansible-relayor, how to ?
by Petrusko 01 Apr '18

01 Apr '18

Hey! I'm planning to try the "ansible-relayor" to deploy some Tor relay instances. If I'm not wrong, it's a main goal ? 2 instances / IP... (soooory for being really noob about this!!!) But I'm lost... not found a tutorial, step by step, you know the tutorial so loved by all noobs! For now, on a fresh Debian8 install, there are : - tor 0.2.9.8 (fresh install from depo, client is ok when opening log file) - ansible - ansible-galaxy install nusenu.relayor - git clone https://github.com/nusenu/ansible-relayor (the folder is stored in my /home...) Will it configure (automatically) many torrc file per instance ? +every key files /relay ? (I'm not too much lost!) Do have I to do this install on every server built ? Or relayor can manage few servers on different locations ? Command lines list use this tool if available ? Many thx for help !!! (and hard work for this tool :) -- Petrusko C0BF 2184 4A77 4A18 90E9 F72C B3CA E665 EBE2 3AE5

Want to help test 'Sandbox 1'? (Linux only)
by nusenu 02 Aug '17

02 Aug '17

Hi, I'm aiming to enable tor's 'Sandbox' feature by default on Debian based relays starting with the next release of ansible-relayor [1]. Before doing so I'd like to collect some feedback from tor relay operators willing to test this feature. If you - run tor 0.3.0.x >= 0.3.0.8 - are on Linux - willing to report proplems it would be greate if you could add the following line to your torrc configuration file: Sandbox 1 Ideally you have also a system monitoring in place that tells you whether this config change has any impact (i.e. on CPU or bandwidth).

Util helping maintain MyFamily
by Ryru 02 Aug '17

02 Aug '17

Hello Everyone I wrote a bash script helping maintaining the MyFamily string in torrc. The idea is to have one single file with all relay nicknames and there fingerprints and generate the MyFamily string uniquely for every node in the family. You will find a copy here: https://github.com/ryru/myfam If you like a bit more background check out: https://blog.addere.ch/2017/07/13/myfam-a-utility-helping-you-maintaining-y… Hope this helps anyone! cheers pascal

Best configuration for high speed exit relay with limited bandwith (1Tb)
by King Queen 01 Aug '17

01 Aug '17

hi, I have a relatively new VPS on CockBox running a Tor exit node. It's the $10/month one https://box.cock.li/ which means it has very fast network (Gigabit I think) but I can only use 1TB per month. I've done some reading round of previous posts on here over the year, and as a result I have variously tried / toyed with RelayBandwidthRate (set at 150KBps so it averages ~800gb/month) and with AccountingMax (15GB with AccountingStart day 00:00) But I don't know what's best for the network. Is it best to have a very fast exit relay for a small portion of the day (so AccountingMax set but no RelayBandwidthRate), a not-so-fast exit relay for more of the day (so AccountingMax set at 15Gb and RelayBandwidthRate at 250KBps) or a slower-still exit relay for all the day (RelayBandwidthRate 150KBps and no AccountingMax?) What is of the most benefit to the Tor network? Also: I read somewhere that Tor should un-hibernate at a random point each day and not directly at 00:00 as set in AccountingStart, but that doesn't appear to be what happens. It just sets off at midnight. To combat any deleterious effect that lots of people doing this might have on the Tor network, if I do use AccountingMax, should I set AccountingStart to a random time in the day? Thanks - your guidance would be very much appreciated. Doug

100K circuit request per minute for hours killed my relay
by Felix 31 Jul '17

31 Jul '17

Hi everybody I observed two circuit bursts around July 19th. On a poor server Tor crashed, on a strong it didn't. The logs below are from the crashed one. I'm on FreeBSD. To my mind the circuit burst exhausts the nmbclusters (not memory, Inact tells). Strong servers have more. How long is more enough ? On FreeBSD nmbclusters is a boot tunable. The strong server took 140k circuits for several hours. Is it worth thinking about a Tor setting like MaxCircuitsPerTime ? MaxAdvertisedBandwidth won't help directly. 1) Normal operation kern.openfiles: 5516 Mem: 36M Active, 1288M Inact, 455M Wired, 1452K Cache, 425M Buf, 191M Free Swap: 3072M Total, 3072M Free USERNAME PRI NICE SIZE RES STATE TIME CPU COMMAND _tor 87 0 309M 283M RUN 125.7H 50.00% tor{tor} _tor 22 0 309M 283M uwait 167:32 3.96% tor{tor} 2) Last minute before crash: kern.openfiles: 5467 Mem: 296M Active, 935M Inact, 692M Wired, 21M Cache, 425M Buf, 27M Free Swap: 3072M Total, 1592K Used, 3070M Free USERNAME PRI NICE SIZE RES STATE TIME CPU COMMAND _tor 85 0 465M 438M RUN 126.8H 43.99% tor{tor} _tor 33 0 465M 438M uwait 186:39 15.97% tor{tor} 3) Crashed: kern.openfiles: 5455 Mem: 295M Active, 936M Inact, 699M Wired, 21M Cache, 425M Buf, 21M Free Swap: 3072M Total, 1592K Used, 3070M Free kernel: [zone: mbuf_cluster] kern.ipc.nmbclusters limit reached sysctl kern.ipc.nmbclusters 126138 Heartbeat: Tor's uptime is 15 days 16:00 hours, with 1611 circuits Heartbeat: Tor's uptime is 15 days 17:00 hours, with 40471 circuits Heartbeat: Tor's uptime is 15 days 18:00 hours, with 88052 circuits Heartbeat: Tor's uptime is 15 days 19:00 hours, with 78444 circuits [warn] Your computer is too slow to handle this many circuit creation requests!

100K circuit request per minute for hours killed my relay
by Pascal Terjan 31 Jul '17

31 Jul '17

Last night for 4h30 (until VPS provider shut it down) one of my middle relays seems to have got in a bad state where it was using 100% CPU continuously It was not using much bandwidth, about 4MB/s, but reading the logs it seems it was getting a lot of circuit requests (70K/minute initially, 100K at the end).

Tor relay operators at DEF CON
by Joel Cretan 30 Jul '17

30 Jul '17

Hi relay operators, If anyone at DEF CON is interested in meeting up, perhaps we could set up a meeting time, maybe in/around the Crypto and Privacy Village. Of course we're all interested in anonymity, so no pressure to speak up. But if enough people tell me they're interested, I'll try to organize something. Hope to meet some of you. Joel
