You relay isn't getting indexed by Authorities?
by Dedalo 13 Jan '15

13 Jan '15

Some months ago I started running another tor relay (middle relay) and something happened, My relay wasn't getting indexed by any authority, neither wasn on atlas. A friend recommended me to make some tests, the problem was the ISP had blacklisted 6 Authorities, but to figure out this I had to make some tests... I made a very simple script which tests if your isp has blacklisted any authority or if you have a problem with your DNS... https://github.com/Dedal0/TorAuthoritiesScript Just run the script in the vps before you setup a relay to avoid indexing problems... The script makes a simple test but is efficient in most of authority cases. Regards, Dedalo -- twitter: @SeguridadBlanca Github: Dedal0 Blog: https://blog.dedalo.in

Extreme Overclocking / Relay Performance
by Thomas White 13 Jan '15

13 Jan '15

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA512 Having discussed this with my partner earlier today, I am curious as to what knowledge the community might have on overclocking a CPU or using other speciality hardware to create an ultra fast Tor relay. I am aware of what IPredator have done but I feel confident better can be done. Has anyone looked into FPGA's at all or know what features, other than AES-NI enabled CPUs could bring big performance boosts? T - -- Activist, anarchist and a bit of a dreamer.

Use an in-memory cache 2. Don't cache images While these strategies might not technically/legally offer much more protection (IANAL): 1. If the cache disappears as soon as the machine shuts down, it's much harder to prove the possession of anything illegal. (However, the proxy headers, live imaging, or an insecure/subverted server might give away what was being cached.) 2. And if images aren't being cached, while textual material could still be illegal, it's less likely to be specifically targeted by law enforcement. In my opinion, if you use HTTP over the internet, you are essentially consenting to caching, inspection, or worse. And most people know that by now. And if you use HTTP over Tor, you should be much more aware of this. teor teor2345 at gmail dot com pgp 0xABFED1AC https://gist.github.com/teor2345/d033b8ce0a99adbc89c5 teor at blah dot im OTR C3C57B23 349825DE 929A1DEF C3531C25 A32287ED

Hi, chutney can be used to setup a large test tor network running solely on a single machine, with no outside network access required. The tor/src/test/test-network.sh script will configure an entire test tor network and verify connectivity from each client through the network. This works best with tor 0.2.6.2-alpha due to some bootstrap speed improvements, although with larger networks you may need to use --delay to increase the bootstrap time. I suggest you start with --flavour basic-min, and move through the sizes to --flavour basic-100 (my machine can barely run basic-100). You can also manually modify the amount of random data sent while verifying connectivity (look for "Octets" in chutney's TorNet.py). It would be nice if this amount was configurable (patches gladly accepted). It would also be nice if these connections were done in parallel, but I don't think that's the case (clarification or patches gladly accepted). teor > Date: Sun, 11 Jan 2015 14:18:01 +0100 > From: webmaster <webmaster(a)defcon-cc.dyndns.org> > > Hi Julien, > > thats exactly the setup I'm actually using.

please put jego00X relays in a "family"

Dear Tor relay operator, thanks for running your relays with such a great diversity (not two relays in the same network). Please be so kind to put all your relays [1] into a so called family to tell Tor clients that these relays are managed by one entity and should not be used toghther in one circuit. thanks! Nusenu The relevant configuration option is: > MyFamily node,node,… > > Declare that this Tor server is controlled or administered by a group > or organization identical or similar to that of the other servers, > defined by their identity fingerprints. When two servers both declare > that they are in the same 'family', Tor clients will not use them in > the same circuit. (Each server only needs to list the other servers > in its family; it doesn’t need to list itself, but it won’t hurt.) Do > not list any bridge relay as it would compromise its concealment. > When listing a node, it’s better to list it by fingerprint than by > nickname: fingerprints are more reliable.

Tor in Spain
by Torizen 09 Jan '15

09 Jan '15

Hello, I've been running a non-exit relay on a EDIS VPS located in Spain for 5 months. Yesterday, without warning, I received an email because apparently I was abussing the network and my VPS was suspended. I was asked to reduce the amount of traffic Tor is allowed to use and after that I received another email where they claimed running a Tor relay, or any other "anonymization software", is now forbidden. I'm from Spain and this is the first time I've heard of this. Does anyone know if this is true? Torizen.
