Using your own Relay as Entry Node
by fr33d0m4all 14 Apr '16

14 Apr '16

Hi, I've seen some time ago a discussion about using your own Tor Relay as an Entry Node, but I'd like to have your opinion in the following two scenarios (if it makes any difference switching from 1 to 2): 1) You point at your node when you're in the same network where the node resides (I mean always by setting EntryNodes in torrc, not by using it as a SOCKS proxy) 2) You point at your node from a different network than the one in which the relay is I think that if your node is being used by others, you would simply be one of the lots of users passing through it, with the advantage of removing the risk of a bad Entry node, what do you think about that? And about using it as a SOCKS proxy to enter the Tor network? Do the same considerations apply or is it even worse to use a relay as a SOCKS proxy? I'm sure that I've read about reasons to avoid using your own node, but I don't remember the considerations about this argument...

I'm running stable 0.2.7.6 from the Jessie repo, I hope the new ARMv8-AES-enabled version will be out "soon" in the repo (but I don't think it will happen soon, at least for the stable branch, right?) BTW, I can't offer more than 14 Mbps, which are about 75% of my upload BW, so I can live for a while without AES acceleration :) You're work is really appreciated!

Hi Tim! I've just started researching www.torproject.org website and doing some practical examination of Tor browser. The great feedback from you. Thanks a lot! Cheers.

Would Tor relays work in a dynamic manner switching from one to another from time to time? I am at the beginning of my research regarding a Tor network and I could use some support from you, guys. I would read a bit about entry, middle and exit relays as well as layers of encryption, but I need more realistic explaination how all of these operate in a practice. Thank you!

important DNS tuning for high volume exit relays, fix for Unbound DNS DOS problem
by Dhalgren Tor 11 Apr '16

11 Apr '16

I believe I now understand the cause of exit relay failure when Unbound is the resolver and GoDaddy null-routes the exit. Both to prevent this DOS from taking out your relay if Unbound is running and to maximize DNS performance: with a local instance of Unbound running /etc/resolv.conf should look like options timeout:5 attempts:1 max-inflight:16384 max-timeouts:1000000 nameserver 127.0.0.1 with a local instance of 'named' running /etc/resolv.conf should look like options timeout:5 attempts:2 max-inflight:16384 max-timeouts:1000000 nameserver 127.0.0.1 background material for the above recommendations found at https://trac.torproject.org/projects/tor/ticket/18580#comment:11 https://unbound.net/pipermail/unbound-users/2016-April/004301.html

First (positive) experiences with a Tor Relay on Raspberry Pi3
by fr33d0m4all 10 Apr '16

10 Apr '16

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA512 Hi, I've just moved my Tor relay installation from my alix1.c embedded system (500Mhz CPU with 256Mb ram) which was able to offer only 4Mbps (100% CPU utilization) to a new Raspberry Pi3 (quad-core 1.2Ghz 64-bit cpu with 1 GB ram). Some days ago I've seen some messages on the ML about Pi2 performance (if I remember well) and I'd like to share my first experiences with Pi3. I have only 20Mbps connection in the uplink direction, so I'm offering about 15Mbps for Tor relay and I've just seen that it is able to offer 14Mbps with 40% of a single core utilization.. In conclusion, I think that a single relay on Pi3 can offer about 30-40 Mbps, and if you run 4 tor relays on the same Pi3 you can offer more than 100Mbps which is definitely not bad for such a small system. The only drawback is that you need to find a good way for keeping it cold, since after 1 hour of 1 core at 100% I've reached about 70°C with heatsinks on the CPU. I just wanted to share my experience with you, hope you find it interesting :) Have a nice week Fr33d0m4All - -- _____________________________________________________________ PGP Key: 0DA8 7293 D561 3AEE A3C0 7F63 101F 316A F30E ECB4 IRC Nick: fr33d0m4all (OFTC & Freenode) _____________________________________________________________ -----BEGIN PGP SIGNATURE----- iQIcBAEBCgAGBQJXCpLUAAoJEBAfMWrzDuy0KpQQAKG1Su24A3O1keFdPGk2zdzw lwEk+pSvRzfoHfmocv5ia9PQ8ZtBws3QfaxfZOYIA0DxdKVK7Rcs+r0ekL6VtAdp y3HU3SlAoCxFDsHycsPhuXZPmQqU/+OAS0lrzo2KrKk/lN/K+b2YYzLfJ+9SWzE1 kg4dcCnWfQrMsLLK72R9qIjSmDsXDGzzNRq0qM3nDjDmE5GPmMJajSbWsHP12v/q BnA786RdB/CDiFVifGPYsKEuughpJ1ryVSRm3LdmTdIjZ+u/sxz0/TQrmj7idgdr TenFk4rf0NbiLU/7sruNJNYPFHvUMUOC8Xu7wBJU2LTF/8fcjYOaQp2UWch4aGQa nM4tMetvhEmoGxcEmJSsi2CHdLkMZ8G67gfufb7Gmsmd59q0KvRQktPxqnJ0GJIs 20x2PX2qzXX7P4mKL8nO0aX32OP+1xScuSH/85Lu6Nnh1jL+T81QPjk/CUHB86ho gbuGt154KEnMoKx+w3aXrzSKVH5kRMgWhIcbRt/xELWprx2zsxGM+gIOCdLQ/vXi PugDblYL8sa8Uds6cz0fjNsuCBI19X0NlnmGFAbU9qOHEhUzYpuF4VlH7sOkL0n2 HWkJTSIjizjZCS0PDPeaqj3lOtoFJiYcAxef+HnGEI/5dameIBB/MDJyOrf+oRfL 1kNo6Zd5KqJesnljCac5 =pk6h -----END PGP SIGNATURE-----
