Bad exit
by grarpamp 17 Sep '12

17 Sep '12

Exit (one of these two I think, no guarantees): 109C56AC68DB55D16E79F832E19313E6C3E47363 67FD1D03F922975269F94EC7E4FD38C6D0E5E900 - torservers? It's not occurring now via them, but whatever exit it was generated these... Error: mail.google.com uses an invalid security certificate.

Massive ongoing google groups spamming
by tor-admin 13 Sep '12

13 Sep '12

Hi all, there is a massive spamming of google groups ongoing. I received several complains as below. From the domain list it seems that all major Tor exit nodes are affected. Running an Exit without custom WHOIS, all abuse message are received by my ISP and forwarded. So I have to temporarily ban google groups. How do other operators deal with this? Regards, Torland "This is some voluminous, off-topic flooding and harassment on the ba.broadcast Usenet newsgroup. It is being reported to abuse reporting mailboxes based on the contents of the NNTP-Posting-Host: and X-Complaints-To: headers, and lookup of the originating IP address via WHOIS and the Network Abuse Clearinghouse. They are sometimes also crossposted to unrelated newsgroups such as rec.arts.tv, soc.culture.new-zealand, and several other newsgroups in the nz.* hierarchy. It is disruptive, and completely off-topic, as well as causing disruptive, cascaded flame wars among those unrelated newsgroups. This user has also been posting from other sources, including 100tb.com, 51.net, 62.net, all.de, bahnhof.se, bayern.de, boingboing.net, broadviewnet.net, ccc.de, formlessnetworking.net, hessmo.com, noisetor.net, oceanic.net, plebia.org, privacyrepublic.org, riseup.net, ru.is, sbcglobal.net, servers.com, snydernet.net, solidonetworks.com, stanford.edu, stargrave.org, torland.me, torservers.net, dmzglobal.com, telstraclear.net, xtra.co.nz, clear.net.nz, orcon.net.nz, netgate.net.nz, freeparking.co.nz, powerusenet.com, giganews.com, thundernews.com, altopia.com, comcast.net, groups.google.com, and tigerusenet.com. It appears that you are merely the latest of his victims. The charter of ba.broadcast is as follows: "This group is here for discussions, comments and program reminders about broadcast media in the San Francisco Bay Area, both radio and television. It also includes cable systems and TVRO/BCRO in the SF Bay Area.

Issues of national interest should be posted to one of the groups in rec.arts.tv or rec.radio." (see: http://groups.google.com/group/ba.broadcast/browse_thread/thread/ddfbd8175e…) The charter does not include sexual innuendo and libel, abusive threats, bigotry and minority bashing, or any off-topic discussion of subjects not reasonably related to broadcasting in the Bay Area, which now consitute the overwhelming majority of current message traffic on ba.broadcast, to the detriment and exclusion of on-topic participation by others.

[OT] ExcludeNodes no longer working
by Scott Bennett 12 Sep '12

12 Sep '12

I know this really belongs on tor-talk, but I haven't been subscribed to it for a long time now. Sorry if posting this here bothers anyone. Back in early July, I upgraded from 0.2.3.13-alpha to 0.2.3.18-rc. I immediately ran into problems with a python script that honors the http_proxy environment variable, which I normally have set to the localhost port for privoxy, which, in turn, connects to tor's SOCKS port. I couldn't really see what was going wrong, but using arm to ask for a new identity seemed to help sometimes to get a circuit that worked. Sending tor a SIGHUP instead also seemed to work about as often. A bit over a week ago, I switched to 0.2.3.20-rc, and the problem still occurs. However, 0.2.3.20-rc now also emits a new message from time to time, the most recent occurrence of which is Sep 06 06:02:45.934 [notice] Low circuit success rate 7/21 for guard TORy0=753E0B5922E34BF98F0D21CC08EA7D1ADEEE2F6B. Wondering whether such circuit-building failures might be related to the other problem, I began a little experiment: each time I saw a "Low circuit success rate" message, I added the key fingerprint of the node in question to my ExcludeNodes list in torrc and sent tor a SIGHUP. The problem is still occurring, though, and when I look at the circuits involved, they all seem to have at least one of the excluded nodes in them, usually in the entry position. So my question is, what changed between 0.2.3.13-alpha and 0.2.3.18-rc (or possibly 0.2.3.20-rc) in the handling of nodes listed in the ExcludeNodes line in torrc? And is there anything I can do to get the ExcludeNodes list to work again the way it used to work? Thanks in advance for any relevant information. Scott Bennett, Comm.

The very best place would be the bugtracker, of course.

But a bug >report on the mailing list is much much better than no bug report at >all.) You switched trackers a year or two ago. I don't recall whether I've tried the new one. Either way, I hesitate to submit a bug report until I'm pretty sure I'm looking at a bug, which is why I asked on this list whether anyone else could suggest anything. > >>> Back in early July, I upgraded from 0.2.3.13-alpha to 0.2.3.18-rc. >>> I immediately ran into problems with a python script that honors the >>> http_proxy environment variable, which I normally have set to the localhost >>> port for privoxy, which, in turn, connects to tor's SOCKS port.

What is the >behavior for the circuits that don't work, and to what extent is >0.2.2.x better? The problem is that the python script in question often has no trouble, but also often does. When it does, it usually gets a good connection twice and fails on the third connection. (Or at least I *think* that's what it does.) Then I either ask tor nicely with arm for a new set of circuits or I pound on tor with a SIGHUP for same, and then try the python script again. The process is slow, so it's very irritating to have to babysit it repeatedly until it finally gets a good connection. If I've left the script a small list of work to do, the failure may come at any point in the list, which then terminates the script. :-( I think it may have an option to ignore errors, but I don't really see an option like that as being very helpful in this situation because it would just fail its way through the rest of the list from that point, but it would take a long time to do that.

Okay. Skipping over local port and IP address usage, here's some client-side stuff. TunnelDirConns 1 PreferTunneledDirConns 1 UseEntryGuards 1 NumEntryGuards [if you really need the number here, let me know--SB] AllowDotExit 0 LongLivedPorts 20-23,47,115,119,143,144,152,178,194,563,706,989,990,992-994,1863,5050,5190-5193,5222,5223,6000-6063,6523,6667,6697,8021,8300 There are also several NodeFamily statements and extensive ExcludeNodes and ExludeExitNodes statements. If there is other stuff you want, let me know, but depending upon what you ask for, I may choose to send it to you directly rather than post it here. > >(To answer your question: looking through the changelogs, and the >commit logs for src/or/circuitbuild.c and src/or/routerlist.c, I can't >find anything that stands out to me as something that might cause an >ExcludeNodes regression.

Fixes bug 5623; bugfix on 0.2.2.25-alpha. It probably has nothing to do with what has been causing me trouble, but it was the only item I found about either of the Exclude{,Exit}Nodes statement that mentioned a change between 0.2.3.13-alpha and 0.2.3.18-rc.

Tor Weather - Node Down
by torhoste＠tor.host-ed.me 12 Sep '12

12 Sep '12

Hi, this is my very first post to this list. I operate tor exit relays vks24784 and vks24949 and subscribed to Tor Weather Reports. Now, at Sun, September 2, 2012 12:17 am and Thu, September 6, 2012 12:33 am, I received "Node Down" Reports for either of the nodes, 1st report for vks24949, 2nd for vks24784. That said, I noticed that these events reset the respective uptime counters at Atlas web application to "zero" and the nodes would lose the already earned stable, guard, named, etc. flags for a certain time period. The problem is that both nodes definitely were online to the best of my knowledge (they are 24/7 actually), please see the official Atlas logs at https://atlas.torproject.org/#details/AAD948023527A6D33FAA96816E4B5F101A664… and https://atlas.torproject.org/#details/B41CBB97CF4DCFF724F272F28FD3F0D683C2F… I even checked the "uptime" through ssh and there hasn't been any reboots occurring. Also, I'm wondering what actually would happen to guard, stable, named, etc. flags if I'd actually need to reboot the nodes cause of maintenance? I feel it unfortunate to lose these flags (also for the Tor network itself(?)) and would like to ask: 1. What does Tor Weather consider a "Node Down" event? 2. How long does it take to regain the mentioned flags? I.e. does the node start from scratch earning them (so to speak), i.e. does it take as long as initially? Last thing I'd like to ask in that context: Do these "Node Down" events and/or needed maintenance reboots have any effect on a potential Tor T-Shirt claim? I'd actually really like to make myself a communicative, green Tor advertising column at some point in time ;-) Thanks!

Um, no, it seems to me that Exclude{,Exit}Node matters are client-side stuff. That's where the circuit routes are selected, which is where those torrc lines come into play, right? > >> Back in early July, I upgraded from 0.2.3.13-alpha to 0.2.3.18-rc. >> I immediately ran into problems with a python script that honors the >> http_proxy environment variable, which I normally have set to the localhost >> port for privoxy, which, in turn, connects to tor's SOCKS port.

I have Right, but the guard's problem really shouldn't be my problem, although I suppose I could try emailing the node's operator about it. >to admit, I'm more interested in the former... Is there a pattern to the >failures? That is for the 7 successes for that node, did you see >anything interesting? Were say, the nodes that worked somehow in the >same country as that guard? Or perhaps were the other failed circuits >all seemingly unrelated to the guard? I haven't the foggiest. I don't even know over how much time tor has been calculating the ratio before it decides to issue that message. It could be minutes, hours, days... The failures I started getting with 0.2.3.18-rc were really irritating, but I didn't have a clue to follow until switching to 0.2.3.20-rc, which issues the interesting messages. That prompted me to turn INFO logging back on and watch what happened when I ran that script. Between the log and looking at arm's display of current circuit routes, I was able to see that nodes were being used that were supposed to have been excluded. > >As far as the ExcludeNodes - did you set StrictNodes at the same time? No. However, there are usually 800 - 900 guards active at any time these days, so I figured that excluding only the ones that gave me trouble would leave plenty of others available for selection. >Are you also a relay? Yes. See MYCROFTsOtherChild in the consensus, descriptors, or tor status pages. It's the same one I've been running for years, apart from short hiatuses in 2007 and 2008. Scott
