"Graceful" Restart of Tor-Relay ?
by mistral.relay＠posteo.net 30 Dec '16

30 Dec '16

Hello all, a newbie question: assuming that I want to shut down and restart a running tor-relay (for whatever reason; e.g. a linux reboot is required) - is it fine to just shut down the relay or is there a nicer, more tor-user friendly way so circuits don't drop for them unexpectedly? I was thinking about a command to tell tor to complete whatever is ongoing, but to not accept any new circuits or other requests and then stop working. Would setting the BandwidthBurst to 0 followed by a tor-reload do this over some time (checking with e.g. arm what is still ongoing)? Many thanks!

TransPort: Convert iptables to pf
by diffusae 29 Dec '16

29 Dec '16

Hello! Does anybody know how to convert this to pf rules in FreeBSD: iptables -t nat -A OUTPUT -p tcp -d 10.192.0.0/10 -j REDIRECT --to-ports 9040 I' running a Tor client in a jail on a different IP and want to route only the .onion traffic through. The DNS stuff is working fine, but I can't find a solution for the above iptables rule, which is working. I like transparently do DNS and Routing for .onion traffic on the network. I looked into the wiki and also find some pf rules, which are routing all the traffic though Tor, but this only works locally. The machine is on FreeBSD 11.0-STABLE. Tor is running in a jail with cloned loopback interface (lo1) and has also a private IP address on the main NIC. Maybe you have some hints. Thanks a lot Regards,

Relay is missing Running flag in the consensus
by Dmitrii Tcvetkov 28 Dec '16

28 Dec '16

Hello, I have a problem with one[1] of my exit relays: about a week ago this relay lost its Running flag, but it was running all the time. I upgraded Tor on this relay to 0.2.9.7-rc from "tor-devel" FreeBSD port and restarted it. Relay was and still is accessible from outside via ports 80 and 443. FreeBSD version is 11.0-RELEASE-p2. After about 24 hours running on new version I decided to check votes from bwauth on detailed page here[2]. Back then the relay had votes for Running flag from maatuuska, dizum and dannenberg. I've checked the relay's ability to open connections to bwauths and it couldn't connect to longclaw - connection timed out, all other bwauths are reachable from the relay. Test was performed by command "openssl s_client -connect <bwauth ip>:443". Ipfw and pf are disabled on the server, there are only tor, ssh and local_unbound running, unbound uses my recursive DNS resolver on another server. DNS queries are resolved fine. Then I saved /var/db/tor directory and started Tor with fresh identity[3], but in about 6 hours it showed similiar symptoms: only maatuska, dizum and dannenberg were voting for it, so I switched back to old identity[1] since. In December 23th I decided to downgrade Tor version back to 0.2.8 from FreeBSD port "tor" and I enabled info level logging. The relay was running since with version 0.2.8.11, at the moment still only 3 bwauth are voting "Running" flag for it: maatuska, dizum and dannenberg. All bwauths except longclaw are accessible from the server. All bwauths are accessible from my neighbour relays in the same datacenter[4][5]. Log info.log has size of 200 megabytes at the moment, first concerning message is: Dec 23 11:54:23.000 [warn] Cannot make an outgoing connection without a DirPort. messages during relay startup, but they disappear eventually: # grep -c 'outgoing connection without a DirPort' info.log 19 They don't look like a reason for the problem. Another anomaly is huge amount of messages like Dec 23 11:54:24.000 [info] router_pick_published_address: Success: chose address '85.143.213.44'. ... Dec 26 13:58:31.000 [info] router_pick_published_address: Success: chose address '85.143.213.44'. # grep -c router_pick_published_address info.log 1653449 I upgraded Tor to version 0.2.9.8 from FreeBSD port "tor". The flood of router_pick_published_address doesn't reproduce with new version. I can compress the log file to 2 mb file with xz -9 and publish it, though I don't want to do it right away because of the warning: Dec 23 11:54:20.000 [warn] Your log may contain sensitive information - you're logging more than "notice". Don't l og unless it serves an important reason. Overwrite the log afterwards. as I don't really know what exact info I should scrub from it. Currently relay is running with identity[1] and version 0.2.9.8 with info logging.

I was made to spontaneously organise one (after I asked a certain Moritz if there would be one) on day 3 (Thursday), 10pm : https://events.ccc.de/congress/2016/wiki/Session:Tor_Relays_Operators_Meetup We currently have hall C.2, which can host ~50 people, but I will try to organise a larger venue based on the success of tomorrow's meetup. Best, and hoping to see you there, nicoo

Otherwise it will pass out without respect to any rule. [] https:// www.freebsd.org/cgi/man.cgi?query=pf.conf&sektion=5#end -- imho, looking forward to 33C3 :)

Hi George Shuklin, thanks for running tor relays. Please do not forget to set the MyFamily parameter in your torrc configuration to tell clients your relays belong to a single operator. If you need help with the MyFamily option let us know. thanks, nusenu https://github.com/nusenu/ansible-relayor https://raw.githubusercontent.com/ornetstats/stats/master/o/potentially_dan…

Minimum requirements for becoming a guard

What are the absolute minimum requirements for becoming a guard? [I am not asking about being trustworthy which I am obviously not, only about bandwidth etc. :)]
