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

TransPort: Convert iptables to pf _ nat

>>> scrub in all >>> nat pass on $ext_if from $NET_JAIL to any -> $IP_PUB >>> rdr pass on $ext_if proto tcp from any to $IP_PUB port $PORT_TOR_JAIL -> >>> $IP_JAIL_TOR port $PORT_TOR_JAIL >> >> That looks good. >> >> There is no "pass out quick" or "pass out on" statement? > > Sure, there is. > pass out on $ext_if proto { tcp udp icmp } all modulate state Remove 'pass' form 'nat pass' if the packet shall flow through the 'pass out' rule after 'nat'. 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 :)

George Shuklin relays: please specify MyFamily in torrc
by nusenu 26 Dec '16

26 Dec '16

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…

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. :)]

iptables stats

This machine is dedicated as a tor-relay. Is it normal that the INPUT bytes count is much greater than the OUTPUT bytes or did I configure the iptables wrong? iptables -L -v Chain INPUT (policy ACCEPT 0 packets, 0 bytes) pkts bytes target prot opt in out source destination 6 328 ACCEPT all -- lo any anywhere anywhere 38 2557 ACCEPT icmp -- any any anywhere anywhere 1135 68123 ACCEPT tcp -- any any anywhere anywhere tcp dpt:http 27432 6416K ACCEPT tcp -- any any anywhere anywhere tcp dpt:https 6274 479K ACCEPT tcp -- any any anywhere anywhere tcp dpt:ssh 93821 129M ACCEPT all -- any any anywhere anywhere ctstate RELATED,ESTABLISHED 1050 54292 DROP all -- any any anywhere anywhere Chain FORWARD (policy ACCEPT 0 packets, 0 bytes) pkts bytes target prot opt in out source destination Chain OUTPUT (policy ACCEPT 70579 packets, 36M bytes) pkts bytes target prot opt in out source destination
