Re: [tor-relays] A few questions about my setting up my first Tor relay.

I'm researching more on Raspberry and I see its way cheaper to run a relay this way. Won't cost me more the 100ε for a relay that will be self-sustaining. Considering there won't be any monthly expenses (except the internet) the initial investment can be recovered, 24/7 relay and no electricity cost, perfect!

"What fraction of the tor network by consensus weight are the openssl-vulnerable relays?"

Why is it empty? Didn't look into it.] - http://ravinesmp.com/volatile/challenger-stuff/vuln1024-combined-uptime.json The 'combined-weights.json' is probably the one you might be after. But that's all I did for now. You also said that these aren't all the vulnerable relays that there are out there. You linked to a more complete list[3], but it has some typos, etc. I haven't done anything with it, maybe someone will take over, or I will do something later on.

False warnings about inaccurate clock
by Stephan 18 Apr '14

18 Apr '14

Hi all, I got two strange warnings within three days that I've never found in my logs before: > Apr 15 21:58:08.000 [warn] Our clock is 1 minutes, 52 seconds behind > the time published in the consensus network status document (2014-04-15 > 20:00:00 UTC). Tor needs an accurate clock to work correctly. Please > check your time and date settings! > Apr 18 15:58:03.000 [warn] Our clock is 1 minutes, 57 seconds behind > the time published in the consensus network status document (2014-04-18 > 14:00:00 UTC). Tor needs an accurate clock to work correctly. Please > check your time and date settings! My "problem" with these warnings is: my server's time is correct. I'm running an NTP demon and verified the time manually - there is not even one second deviation, much less nearly two minutes. Has anyone else experienced such warnings these last days? Is it really my server or could it be an error with the consensus network status document? -Stephan

Well, this really convinced me on using Raspberry as a relay. Very nice guide. Due to the very low power consumption I'm thinking on setting relays that are battery and solar powered (I'll build some grapheme supercapacitators) and using an anonymous internet connection (3G/4G via a mobile router, very easy to obtain). Could be something nice.

Re: [tor-relays] Init.d script for two simultaneous Tor instances
by Jesse Victors 18 Apr '14

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA512 I prefer "ps aux | grep tor" and then you can seem them running side by side. You can also seem them on htop, which I prefer over top. My init.d script sets a different log file to each instance, allowing you to monitor the logs of each independently. If you are clever though, you could do something like alias torlogmon='watch -n 10 "cat /var/log/tor/notices.log | tail -8 && echo \"***************\" && cat /var/log/tor2/notices.log | tail -8"' and watch the logs of both at the same time. If you want to use arm you will have to set arm up for each instance. I've been moving away from arm in favor of other tools, one of which is "speedometer", a nifty package that allows you to monitor bandwidth usage remotely. If Tor is the only thing on your machine, you get basically the same thing as the arm graph. alias speedometer="speedometer -l -m 1048576 -rx eth0 -c -tx eth0" Where 1048576 is the maximum bytes/sec value that will be shown in the y-axis on the linear graph. Modify depending on your utilization. I prefer working with powers of 2 with this. The man page is useful of course. Jesse V.

Re: [tor-relays] Init.d script for two simultaneous Tor instances
by Jesse Victors 18 Apr '14

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA512 Yes, it's better to have faster relays. However, if you are setting up a relay or exit on a gigabit connection it may take some time before you see significant utilization of the pipe. By running two Tor instances at once you can increase the contribution of the Tor network without sacrificing the speed of either relay. Monitoring and good judgment is key here, I wouldn't run multiple relays on a slow computer or one with a slow Internet connection. Watch the logs and just make sure everything is running well, as always. Jesse V.

A few questions about my setting up my first Tor relay.
by Robert Smith 18 Apr '14

18 Apr '14

Judging by the level of your computer skills implied by the emails, those involved in Tor have better things to do than help a guy like me. I think it is important to the entire world that the internet links us together, and Tor may be the most crucial part of that. I have 3 machines as possible candidates for a Tor relay: A) A decent PC (around 6 years old) with Vista installed. It's been unused for 2 years. I am willing to do a clean re-install of Vista or even Linux (with help) to run it as a Tor relay, night and day. B) A MacBook Pro (4gb ram, Intel, Snow Leopard). Again, I am willing to wipe it, and do a clean install of the OS and use it for a Tor relay, night and day. C) My personal laptop an Asus G74S (12gb ram, i7 quad core 2.2ghz, Win7 Home Premium 64bit), which I "sleep" most nights. Modem: DSL from "Telus" (in Victoria, BC, Canada) with 4 ports (I use 1 cable port to my personal computer, 1 wireless port for my iPad or Android cell phone). Questions: 1) If I run a Tor relay with that modem, are there any security risks to the other devices? I am no technical guru. 2) If I run a Tor relay on either (or both the Vista PC and MacBook) of the computers mentioned above, will it be mostly a "set it and forget it" maintenance? I cannot devote much time (and definitely don't have much expertise). 3) Will I compromise the anonimity of Tor users due to my lack of technical skills while running a Tor relay? I don't want to do more damage than good. 4) Can I throttle down the bandwidth on my Tor relay(s) when I need it for my own personal machine? I don't want to disrupt the Tor net. 5) Can you suggest the best way to use my machine(s) to make a reliable, maintenance free and secure Tor relay, requiring the least amount of time? I am guessing it's the MacBook cabled to the DSL, running only Tor relay software, and running only a normal relay. 6) At this point is it worth my while, to attempt a Tor bridge or exit relay or am I even capable of doing it properly? I have little experience or expertise in networking and not much time. Thanks for spending your valuable time reading my questions. I hope to make it pay off, in a long term Tor relay. Rob Smith
