Considering setting up an exit, need advice
by Jesse Victors 28 Jan '14

28 Jan '14

Hello everyone, I'm thinking about setting up an exit here at my university here in the US. My ISP has no problem with Tor relays on the fast connections, but I haven't inquired about exits. I'd be running the exit on a surplus computer that I have control over in a lab in one of the main buildings. How do I ask my ISP about it? I'll be doing some research as to what ports I can open to contribute yet avoid being flooded by complaints, but if anyone has any tips I'd appreciate it. Would it be a good idea to copy the exit policy of the node at MIT? Is there a way to configure the Linux firewall so that only Tor has Internet access, in order to help show that I wasn't behind anything that comes out of the exit? I'm basically just looking to get started here if this is feasible, and looking for advice.

NTor handshake
by Sebastian Urbach 27 Jan '14

27 Jan '14

Hi, May i ask when the NTor handshake is going to be recommended by the majority of the directory authorities ? It's probably not a surprise that i prefer NTor handshake as a relay operator. I checked constantly since the switch to 0.2.4.20 and the values are pretty constant. (35k TAP / 700 NTor). I didn't notice any complaints so i assume that it should be possible to push forward. -- 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

To anyone whom might give a suggestion or answer. Just set up tor browser and relay package wanted to volunteer my computer and connection to those in parts of the world who don't have as much freedom of accesses as us.Question if I just set my computer to not go into sleep mode is that all that is needed to let people use my connection when I am not using it.Specs home built as-rock 787 pro3 8gig of ram dsl connect low speed att offers.

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
by Sebastian Urbach 26 Jan '14

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 25 Jan '14

25 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

Re: [tor-relays] Would be good if Tor were more multithreaded.

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.
