Need advice on IPv6 bridge config
by Steve Snyder 19 Sep '12

19 Sep '12

I'm getting my feet wet with IPv6 bridges, so far without success. I set up a test bridge (0.2.3.22-rc) on one network and plugged the address:port into Vidalia (TBB x86_64-2.2.39-1) on another. The bridge config looks like this in part (local IPv4 address hidden): Address aa.bb.cc.dd OutboundBindAddress aa.bb.cc.dd ORPort [2a00:1d70:ed15:37:235:53:64:0]:443 At run time the final Tor log entries are: [notice] Tor has successfully opened a circuit. Looks like client functionality is working. [notice] Bootstrapped 100%: Done. In Vidalia the message log entries are: [Notice] Learned fingerprint 24432B99CA2533BC95ABF66C7AFE835F96DD2B2D for bridge 2a00:1d70:ed15:37:235:53:64:0:443 [Notice] no known bridge descriptors running yet; stalling That last line is repeated periodically forever. So I have enough connectivity to correctly determine the fingerprint, bit not enough to get bridge descriptors. What am I doing wrong? Thanks.

Bad exit

Exit (one of these two I think, no guarantees): 109C56AC68DB55D16E79F832E19313E6C3E47363 67FD1D03F922975269F94EC7E4FD38C6D0E5E900 - torservers?

Massive ongoing google groups spamming
by tor-admin 14 Sep '12

14 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.

[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. Quitting outright is much faster. > >>> A bit over a week ago, I switched to 0.2.3.20-rc, and the problem >>> still occurs.

Okay. Skipping over local port and IP address usage, here's some client-side stuff.

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!
