Unmeasured - 69D9FF1BE14B9AE77701A6BCBC075FF837F5AFF9

Greetings, my relay 69D9FF1BE14B9AE77701A6BCBC075FF837F5AFF9 (darkmatter) recently (3 days) received an Unmeasured flag and is considered to be offline. I could not detect any issues on my side and wondered if you could help me to resolve this. Best regards, Dark

Exit in Turkey blocking torproject (komm EA93C), BadExit, Node Subscription Services, Censorship
by grarpamp 02 Sep '18

02 Sep '18

This particular case receiving mentions for at least a few months... D1E99DE1E29E05D79F0EF9E083D18229867EA93C kommissarov 185.125.33.114 The relay won't [likely] be badexited because neither it nor its upstream is shown to be doing anything malicious. Simple censorship isn't enough. And except for such limited censorship, the nodes are otherwise fully useful, and provide a valuable presence inside such regions / networks. Users, in such censoring regimes, that have sucessfully connected to tor, already have free choice of whatever exits they wish, therefore such censorship is moot for them. For everyone else, and them, workarounds exist such as,,, https://onion.torproject.org/ http://yz7lpwfhhzcdyc5y.onion/ search engines, sigs, vpns, mirrors, etc Further, whatever gets added to static exitpolicy's might move out from underneath them or the censor, the censor may quit, or the exit may fail to maintain the exitpolicy's. None of which are true representation of the net, and are effectively censorship as result of operator action even though unintentional / delayed. Currently many regimes do limited censorship like this, so you'd lose all those exits too for no good reason, see... https://ooni.torproject.org/ https://en.wikipedia.org/wiki/Internet_censorship_and_surveillance_by_count… And arbitrarily hamper spirits, tactics, and success of volunteer resistance communities and operators in, and fighting, such regimes around the world. And if the net goes chaotic, majority of exits will have limited visibility, for which exitpolicy / badexit are hardly manageable solutions either, and would end up footshooting out many partly useful yet needed exits as well. If this situation bothers users, they can use... SIGNAL NEWNYM, New Identity, or ExcludeExitNodes. They can also create, maintain and publish lists of whatever such classes of nodes they wish to determine, including various levels of trust, contactability, verification, ouija, etc... such that others can subscribe to them and Exclude at will. They can further publish patches to make tor automatically read such lists, including some modes that might narrowly exclude and route stream requests around just those lists of censored destination:exit pairings. Ref also... https://metrics.torproject.org/rs.html#search/as:AS197328%20flag:exit https://metrics.torproject.org/rs.html#search/country:tr%20flag:exit In the subect situations, you'd want to show that it is in fact the exit itself, not its upstream, that is doing the censorship. Or that if fault can't be determined to the upstream or exit, what would be the plausible malicious benefit for an exit / upstream to block a given destination such that a badexit is warranted... a) Frustrate and divert off 0.001% of Turk users smart enough to use tor, chancing through tor client random exit selection of your blocking exit, off to one of the workarounds that you're equally unlikely to control and have ranked, through your exit vs one of the others tor has open? b) Prop up weird or otherwise secretly bad nodes on the net, like the hundreds of other ones out there, for which no badexit or diverse subscription services yet exist to qualify them? c) ??? Or that some large number of topsites were censored via singular or small numbers of exits / upstreams so as to be exceedingly annoying to the network users as a whole, where no other environment of such / chaotic widespread annoyance is known to exist at the same time.

Policy Question: Tor Exits at Universities, Corporate Networks, etc
by Nathaniel Suchy 02 Sep '18

02 Sep '18

Recently we've been discussing a Tor Exit in Turkey censoring access to various websites. It's less to some err, disagreements on what should and should not be allowed. I've seen a few opinions: *) It grants an outside view at what Turkey censors *) It could push new tor users away This leads me to question if it's okay for a Tor Exit to be on a censored network are the following scenarios now allowed? *) A Tor Exit behind a Corporate Network and Web Filter *) A Tor Exit behind a University Network and Web Filter Under the logic with the Turkey exit relay it should be right? Cordially, Nathaniel

Message to devs, please don't change log strings
by gustavo 02 Sep '18

02 Sep '18

Hi In the last few months I started to monitor more closely my relays parsing their logs, but every new update changes the log strings. Can the devs be mindful to relay ops and not change strings needlessly? Here is an example 0.3.3.9 Sep 1 00:01:32 serverhostname tor[15341]: Sep 01 00:01:32.042 [notice] 0.3.something Sep 1 00:01:32 serverhostname Tor[15341]: Sep 01 00:01:32.042 [notice] 0.2.9 Sep 1 00:01:32 serverhostname Tor[15341]: [notice] I'm logging to syslog thanks! -- IRC: gfa GPG: 0X44BB1BA79F6C6333

Abuse Complaints
by Paul Templeton 30 Aug '18

30 Aug '18

Question: are exit operators seeing many abuse complaints now days? I have only had one in the last two months from 5 exits. I used to see a lot now nothing really. I just find it weird. Paul 137CF322859E400455E457DB920F65FFDD222CDF

log "Is your outbound address the same as your relay address?"
by Tim Kuijsten 30 Aug '18

30 Aug '18

Hi, I just setup a new relay[0]. One of the messages I got is the following: "Your relay has a very large number of connections to other relays. Is your outbound address the same as your relay address? Found 12 connections to 8 relays. Found 12 current canonical connections, in 0 of which we were a non-canonical peer. 4 relays had more than 1 connection, 0 had more than 2, and 0 had more than 4 connections." When I had setup another relay last week[1] I got the same message, and it didn't reappear so I assume this is about starting up a new relay and is nothing to worry about. I just thought I'd let you know. The hostnames of both machines matches the public dns and reverse dns names. Furthermore each machine has only one public ipv4 address, which is also set in it's local /etc/hosts file. At one machine I had set "Address" in the torrc as well, but this didn't avoid getting this message once. Kind regards, Tim [0] tosk B183A69592D2E8C8C487C054D0849E3C9561DC11 [1] kali 2C76951164C5184A3B8B7CC1914B34E4622B225F

Test bed in MyFamily?
by Totor be 30 Aug '18

30 Aug '18

Hi list, Just a quick question about families: I'm in the process of setting up a 4th relay as test bed VM in order to validate the Linux and Tor updates before updating my 3 live relays (none of these are exits) This 4th relay will be fully operational, but will only be started from time to time, when updates are available After the updates are installed, I plan to leave it running for half a day or so until it appears in Tor Metrics Question: should I include this test bed relay in MyFamily or leave it completely stand alone? What would you recommend? Thanks! Patrick

Limiting open port RST response from N to M packets/sec (FreeBSD)
by nusenu 30 Aug '18

30 Aug '18

Hi, I'm curious as to how frequent FreeBSD relay operators that do not make use of any packet filter get something like the following line in their logs: kernel: Limiting **open** port RST response from ... to 200 packets/sec -- https://twitter.com/nusenu_ https://mastodon.social/@nusenu
