Freebsd trial with greypony.it was a success
by zimmer linux 24 Aug '18

24 Aug '18

Hi, Conrad Rockenhaus - with your guidance and support with freebsd, within just 21 days total running time, you have helped me set up and manage the fastest exit relay in all of Canada. See https://metrics.torproject.org/rs.html#search/country:ca%20flag:exit https://metrics.torproject.org/rs.html#details/D9B1E08CC91F7F42EEE5578EA8B0… Give yourself a pat on the back. If anyone wants to talk through running a freebsd relay, feel free to contact me off list. Zim

Snowflake PT
by Nathaniel Suchy 24 Aug '18

24 Aug '18

Hi everyone, Tor Browser 8 Alpha includes the Snowflake PT as it comes near a final release, the adoption and usage of the Snowflake PT will continue to rise. I now have the following questions... 1) Will a command line tool like an obfs4proxy come out so those of us with infrastructure can run high capacity snowflake bridges. 2) Is the goal to replace OBFS4 with Snowflake or will they continue to co-exist? 3) How does Snowflake attempt to obfuscate, if at all it's traffic? How strong is the cryptography compared to obfs4proxy Looking forward to learning more about this :) Cordially, Nathaniel Suchy

Dropping packets with TCP MSS=1400 to foil GFW active probing
by David Fifield 22 Aug '18

22 Aug '18

A paper from FOCI 2018 by Arun Dunna, Ciarán O'Brien, and Phillipa Gill on the subject of Tor bridge blocking in China has this interesting suggestion (Section 5.2): https://www.usenix.org/conference/foci18/presentation/dunna To do this, we write a series specific rules using iptables in order to drop packets from Chinese scanners. ... We use a rule to drop incoming Tor packets with an MSS of 1400. Further investigation would be needed to analyze potential false positives... We note that this method of dropping scan traffic successfully keeps our bridge relays from being blocked and allows our client in China to maintain access to the bridge. Like https://github.com/NullHypothesis/brdgrd, surely this trick won't work forever, but if you're setting up a new bridge, it's worth a try? This is completely untested, but I think the iptables rule would look something like this: iptables -A INPUT --protocol tcp --dport [your-bridge-port] -m tcpmss --mss 1400 -j DROP Then, after a while, check /var/lib/tor/stats/bridge-stats and see if you have any connections from "cn".

Interested in running a FreeBSD Relay on Cogent?
by Conrad Rockenhaus 21 Aug '18

21 Aug '18

Would you like to trial a FreeBSD Relay on Cogent until October 1st? Yes, it has to be FreeBSD, because I use Bhyve as my hypervisor and some of my blades don’t support UG, which means, I support FreeBSD only on these series of servers. If you’re interested in a Model “A” (25GB HDD, 1vCPU, 2GB RAM, burstable up to 1gbit of bandwidth/unlimited transfer) running FreeBSD and would like to try it out until October 1st, just send me your Public Key. My hope is you will keep it online and hopefully increase the BSD Relay percentage to 7%. After October 1st its only $15/mo, which is my costs alone. You don’t have to worry about abuse complaints, I handle that for you. You just worry about running your exit and maintaining your OS. I take care of everything else. If you’re interested, send me a public key. Thanks, Conrad

Rendezvous on non-OR circuit?
by tor-markus 20 Aug '18

20 Aug '18

I've been running a tor relay for several days now (C65EF5E06B8338CF976D376048BE2C8FBD499C9C). During my regular checks I noticed something odd within the tor log files. [WARN] Tried to establish rendezvous on non-OR circuit with purpose Acting as rendevous (pending) It occurs several times per hour and I couldn't find anything except the [bug tracker](https://trac.torproject.org/projects/tor/ticket/15618) which seems to be outdated (newest message is four weeks old). I'm concerned that this could be some kind of "attack" that could compromise users, as I'm running an exit node. Does somebody have more information on this matter?

question related to consensus weight fraction calculation
by Toralf Förster 19 Aug '18

I do wonder about any changes in the algorithm which drops the cw of a relay [1] by a magnitude within 1 year as seen in [2]?

How long before a new relay shows up in Relay Search?
by hanzer＠riseup.net 17 Aug '18

17 Aug '18

Hello, I've recently set up a new relay: Tor 0.3.3.7 (git-035a35178c92da94) on a FreeBSD-11.2 machine. The Tor server's identity key fingerprint is: 'Chiron420 9C7BB4BCB58AC876D83B67277A0CF3BC73F4FDF6' A search for this relay on the metrics site says "No Results found!" <https://metrics.torproject.org/rs.html#search/Chiron420%209C7BB4BCB58AC876D…> Is this typical or might there be something awry in my setup? Thanks!

Random Relay Reset On Mac OS + OS Support Question
by Keifer Bly 17 Aug '18

17 Aug '18

Hello, So something strange happened recently with my relay running on Mac OS via homebrew at https://metrics.torproject.org/rs.html#details/DB1AF6477BB276B6EA5E72132684… Just this morning, my relays uptime had been reset to 0 days. When I checked the software it indeed said the uptime was back to six hours. This is odd as I did not reset thee software within the last 24 hours (that I remember), there was a brief time when my network went down due to an ISP glitch however has been working fine ever since. I am wondering, do newer versions of the tor relay software automatically reset if they detect the internet is unreachable? I also have one more question, around when does tor / homebrew drop support for older versions of an OS? I am asking this because the computer that runs this relay is a 2011 iMac, and Apple has confirmed it will run the new MacOS coming this year (Movari) however versions of macos afterwards are unconfirmed. Thanks all.

Shutdown by ISP / Hoster? [was Albania]
by grarpamp 16 Aug '18

16 Aug '18

When these ISP's give their shutdowns and excuses, regardless of size of ISP, you could in turn... - Offer to work there, they probably need the help, and you get something from the experience. - Start your own, customers probably need the services, and would be willing to pay. Why vote with only your own customer dollars, when you can add your brain and voice into the production.
