Re: [tor-relays] Scoreboard enhancements / Trying Trusted Tor Traceroutes

Hi Renke, Do you care to elaborate ? If you need assistance we can talk via private mail as well ... Bandwidth consumption is very low as you possible read on the project site. Do you run the test with scamper and or did you turn down the scanning speed ? The question remains why did many relay ops canceled the test before completion. As the scoreboard shows most of them would have completed the test in the estimated lowest time frame (around 4 days). The estimated max. time is about 24 days not 96 if you choose to run with traceroute and the default values instead of scamper. My best guess is that even 4 days was too long. After the test was started they wondered how long it would take and checked back with the faq, then decided to quit. Call it a hunch ;-) My system, as an example, took about 2 days and 23 hours to complete the run. I use scamper with the default settings. You can also turn up the pps value and finish even faster. How long will this take?: http://web.engr.illinois.edu/~das17/tor-traceroute_v1.html#q-howlong How much bandwidth, disk space, RAM, and CPU will this consume?: http://web.engr.illinois.edu/~das17/tor-traceroute_v1.html#q-howmanyresourc… -- Mit freundlichen Grüssen / Sincerely yours Sebastian Urbach ---------------------------------------------- Those who would give up essential Liberty, to purchase a little temporary Safety, deserve neither Liberty nor Safety. ---------------------------------------------- Benjamin Franklin (1706 - 1790), Inventor, journalist, printer, diplomat, and statesman > I am wondering why only 68 out of 283 completed the traceroute.

Scoreboard enhancements / Trying Trusted Tor Traceroutes

Dear list members, Sorry for the completely empty mail a few minutes ago. What can i say, it's sunday and i had way less sleep than i should. But here the good news. The live scoreboard was modified. There is now a new column which shows the number of completed runs per IP and also at the bottom a value which displays the total sum of systems who completed at least 1 run. The board: http://128.174.241.211:443/relay_scoreboard Thanks for your attention. -- Mit freundlichen Grüssen / Sincerely yours Sebastian Urbach ---------------------------------------------- Those who would give up essential Liberty, to purchase a little temporary Safety, deserve neither Liberty nor Safety. ---------------------------------------------- Benjamin Franklin (1706 - 1790), Inventor, journalist, printer, diplomat, and statesman

How effective is "NumCPUs"?
by Alexander Dietrich 24 Jan '14

24 Jan '14

Hello, a relay I'm running is currently at about 0.80 load average. It has a dual-core CPU and I have configured "NumCPUs 2". I'm still in the process of finding the bandwidth limit. Should I keep increasing "RelayBandwidthRate" on the single Tor process, or is it a better idea to start a second process? (Also, does a second process need its own identity, or can it use the existing one?) Best regards, Alexander -- PGP Key: 0xC55A356B | https://dietrich.cx/pgp

I've added "numCPUs 2" to torrc and restarted via the init script. It does not seem to have made a difference. I presume that's where/how it should have been added? The FAQ says it doesn't do multi-core well. Seems unfortunate - multi-core is everywhere, now.

Trying Trusted Tor Traceroutes
by Sebastian Urbach 24 Jan '14

24 Jan '14

Dear list members, Some relay operators asked if it would be useful to run the script multiple times on the same system. The short answer is yes. It was unclear if enough operators would be willing to help with the script even one time. No one expected that there would be operators who like to do more than one run :-) Thats awesome ! Multiple runs could show temporal routing changes and therefore valuable new information. The value for multiple runs will be implemented into the live scoreboard within reasonable time. Thank you very much for participating ! You want to help ?

Hi Alexander A Tor daemon running with numCPU2s is better than a single daermon on each core because there is less "overhead". You can also get a great boost by enabling AES-NI hardware encryption if you don't have it already ...

So I just started using Tor and I`m getting "The connection has timed out" It doesnt look like I can set up a relay,any hints would be awesome.Thanks in advance.
