Unless you've been really messing with your configuration, you're likely to end up hopping out of your home country at least once per circuit anyway. And if the network is slow, you'd want your traffic to get out of there as soon as possible; no/little sense adding a relay in a slow network area. Exit relay positioning is more dependent on filtering and network diversity rather than geographical proximity; I can only see that being helpful for guard relays. That said, if we're low on Australian relays it'd be good to get more there. I believe both UK and Australia keep bouncing around ideas for legally-required net filtering; that's the only thing I'd keep in mind other than speed when choosing between them. -- PGP key available on request

Effectively donating bandwidth
by Curtis Gagliardi 30 Apr '15

30 Apr '15

I'm running a relay with the extra bandwidth on my VPS, but I'm unsure if it's optimally configured. I have 2.5TB of bandwidth I want to use every month. Given that, how do I configure my relay in the most helpful way? The docs mention dividing my bandwidth by 30 and setting an accounting max of 1 day. It also suggests "You might also consider rate limiting to spread your usefulness over more of the day". What not use an accouting period of a month and spread it out over the full month? Spreading it out feels like the right thing to do, but is it actually the most helpful? Maybe burning my bandwidth is faster bursts is more helpful. If spreading it over the month using a low bandwidth rate and a monthly accounting period is ideal, is there a better way to configure it than busting out a calculator and coverting TB/month to KB/s? How should I determine my BandwidthBurstRate? I understand what it is, but should it be defined in relation to my bandwidth rate? Thanks in advance, Curtis Gagliardi

(onion / directory) The second instance would be able to use another of the processors on your multiprocessor machine. (Unfortunately, tor multithreading only offloads some of the work.) There is currently a limit of two instances per IP address, but if you have 2 IP addresses, you could potentially run 4 instances, one instance per processor. teor teor2345 at gmail dot com pgp 0xABFED1AC https://gist.github.com/teor2345/d033b8ce0a99adbc89c5 teor at blah dot im OTR D5BE4EC2 255D7585 F3874930 DB130265 7C9EBBC7

running multiple bridges on one machine?

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA512 hello relay operators! i've asked this question on IRC once or twice, but it seems the right people aren't online/active when i am. i think i might be able to get a better audience to answer my questions here on the mailing lists. let's begin: is it possible to run 5 bridges on one low-end VPS? each bridge would be hosted on a different IP address from five different /24 IP blocks, so that's not an issue. would i have to use multiple Tor processes, and would 5 processes be too much for a 2-core VPS with 256mb memory? also, how much bandwidth does a bridge normally burn through per month? on said VPS, the economical choice is to provide 200gb bandwidth per month. if that is not sufficient, the offer isn't financially feasible. thanks for all you do! - -- @syndikal A9FF 2FE3 A171 FE53 AEC3 A0F9 72B5 44E0 4417 11B2 twitter.com/syndikal -----BEGIN PGP SIGNATURE----- iQIcBAEBCgAGBQJVPuKmAAoJEHK1ROBEFxGyfUQP/irH1HzKPCe+t9TFSMignsRq oX5tK6YfInQ7vmfdhpPyHodM6DneeC1uBVdY6+qyJ6g3Ef5JXblSua+2zqJe8mlI rlwL9ll+i4tYSquqpaht3dWU1xY/UoqnlwCSO8+xaCz0zYBmOafib1MHI8nCDblp Y1PXMVWs3nhaXP/ev8JS3y8HuVeVy03lRF8pAaxKJmFI5YZJpNqHO/gVXTwU0O6M OrlqPT/YPmN/cD00TrnT5k+dVEHIPzEt7vK20NlUfCTS7vLOZync+jwRBYPzS6es fFq7C/gTP3oxyx6RIGLXpHEtKmvUwQeC89GKrgrDfb0EynX7bZ+jcvzXBCq5TPFz rgz19ogAbDZ167FshkVhMc+twfhkaq1FN2ADIHF7iIFLd6z93Img3IVMk+i2nijy lb4CtfHFqhJKSxuAfUYVFHx5GnC2u37gOCKdF+ZOCtpOAyP7ozrSwVYLY+OjsPf2 7F9dq22x8QxOdSccyK4lrmyl0SZpliMDCIoJk4IvJT2elqStntwH/Ecur2I48mWv UvPcwUEbsUhZg/u3xDkuvhB5zcVYB01gqbFSr8N7nYgMgx9Ww7lVVMmj+2ADQS9e ttOHmck50ewjz/EVN/xbWcemdGyiNl1M0aPyoysWgn/8TZ12TLhAL1jgJxOJFE99 7K8kTak9an5FOf+RbpY6 =eeGb -----END PGP SIGNATURE-----

Hi there, After a long month of not having time for this, I've got it working thanks to Sina's help.

Although the information on the subject is scattered across several issues on this list, I hope others can use it to build some bridges! http://www.zipplet.co.uk/index.php/content/raspberrypi_golang was a useful page on getting go 1.2 or higher installed on a Pi2.

Hi I just wanted to let you know that Washington sent us a subpoena regarding one of our exit nodes in Romania. They want to know the real IP behind the Tor Network. I mailed them what Tor is and why I can't help them in identifying this person. Nevertheless I will give you the link to the full subpoena. Maybe you guys find it interesting. I will forward the subpoena to our lawyer as well. https://mega.co.nz/#!ilIjlZSb!-deirKharWaDtp_UMxhev58E14zeouyoWUbzxeWPvEQ Greetings -- Sam Grüneisen - President Frënn vun der Ënn A.S.B.L. enn.lu

Relay Consensus Weight
by Marco Morgia 24 Apr '15

24 Apr '15

Hello, on friday my realay's Consensus Weight felt down suddenly to 20 and the its bandwidth is not used anymore (https://atlas.torproject.org/#details/94212674A2C6AEBF77354D959D464E49BC878…) I don't understand why, as nothing is changed in its configuration. And, I don't know if it's related, but I noticed that the tor network has slow down in the last days and some times it's very difficult to use it.
