An application which formats them ready for printing, calculates the stamp required, perhaps also prints some customs stickers depending on destination. Here volunteers can easily help and there's no need to hide such discussions, because such software doesn't require the real data, can be written/tested with dummy data instead. All the trusted person (you) has to do is to run this software on the real data and hit the "print" button. Your post office or shipping company might have software like this already - and if it's done using their software, getting the stamps and stickers right is their responsibility, not yours. Of course, this software might not be free, in either sense of the word. 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

Determining geographical locations for a new exit relay would help most
by Seth 04 May '15

04 May '15

I'm standing up a new exit relay on the VULTR network. How would a person go about determining which location is in most need of additional exit relay capacity? Available locations: https://www.vultr.com/locations/ * Miami, Florida * Chicago, Illinois * New York / New Jersey * Dallas, Texas * Seattle, Washington * Atlanta, Georgia * Los Angeles, California * Silicon Valley, California * (AU) Sydney, Australia * (Asia) Tokyo, Japan * (EU) Amsterdam, NL * (EU) London, UK * (EU) Paris, France * (EU) Frankfurt, DE Also, curious to hear people's thoughts on any potential jurisdictional arbitrage benefits to be gleaned by choosing a location other than ones country of residence or citizenship. For the sake of argument, consider a VULTR account opened by U.S. citizen residing in the U.S. Choopa LLC (VULTR parent company) is also a US based company. http://start.cortera.com/company/research/k5o8lvm2j/choopa-llc/

Why can't I see authorities bandwith stats
by Dedalo 04 May '15

04 May '15

Hi, I was making some changes in my relay configuration and I made some queries in GLOBE and ATLAS and something happened. I noticed that all authorities are not showing bandwidth stats from the last week and I was wondering why. Regards, Dedalo. -- twitter: @SeguridadBlanca Github: Dedal0 Blog: https://blog.dedalo.in

Re: [tor-relays] T-shirts and Confirming Relay Control

Matt, Inspired by the options to confirm domain ownership with Google, Could you ask the relay operator to include a randomly generated (by you) token in their contact field? It may take a while to propagate and it requires action on the operator's part, but it's not difficult and I expect it provides the assurance you need. > On 05/03/2015 04:20 PM, Matthew Finkel wrote: >> On Sun, May 03, 2015 at 12:05:49PM -0700, Aaron Hopkins wrote: >>> On Sun, 3 May 2015, Matthew Finkel wrote: > >>> Or as Robert suggests, just send verification mail to the listed contact >>> address of the relay.

OS X still ships with OpenSSL 0.9.8 by default. But Darwin is such a small fraction of the network, and it's less likely that a Darwin server would push enough data to get a t-shirt unless it had an OpenSSL version with aes-ni. 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

Drop in relay count
by Linus Nordberg 03 May '15

03 May '15

Hi, Looking at the graphs showing the number of relays in the network it seems like we've lost about 500 (-7%) relays since the beginning of this year. https://metrics.torproject.org/networksize.html?graph=networksize&start=201… https://metrics.torproject.org/networksize.html?graph=networksize&start=201… Looking at the graphs showing the total relay bandwidth of the network it seems like the advertised bandwidth has increased with about 25 Mbps (+23%). https://metrics.torproject.org/bandwidth.html?graph=bandwidth&start=2015-01… https://metrics.torproject.org/bandwidth.html?graph=bandwidth&start=2012-01… Seems a bit contradictory at first sight. A guess would be that a lower number of fast relays have replaced a higher number of slow ones but I haven't looked into it more. Anyone who's looked into this? And can back up their theory with some numbers. Thanks, Linus

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?
by syndikal 28 Apr '15

28 Apr '15

-----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-----
