ORCONN
by Yannick Krueck 04 Sep '14

04 Sep '14

Hello, I provide a Tor-Relay Server. I have a questions regarding the Tor control protocol. If i use "setevents orconn", i get a lot of Connections. Mostly i get first a "New/Launched" message, then a "Connected" message and then a "Failed/Closed" message. But sometimes i get only a "New"-message, and a "Connected" message, but I never receive a "Failed" or "Closed" message. In this case, i only get the IP Adress, but no LongName. For example: 650 ORCONN 81.219.94.108:1976 NEW 650 ORCONN 81.219.94.108:1976 CONNECTED => Never Receive a Closed oder Failed Message Additional i can not find the IP-Adress 81.219.94.108 on https://onionoo.torproject.org/details . The question: What or Who is 81.219.94.108? Another relay? A Bridge? A normal User (Entry Guard)? 81.219.94.108 is only an example, their are many more Nodes with the similar procedure. Thank you for answering my question Y. Krueck (Germany)

Hi, I like to suggest adding oniontip.com to the "Donate" section on the tor website. It's a nice possibility to help the Relay-Oerators.

is a KVM fine for a first quick test to setup a tor exit node
by Toralf Förster 02 Sep '14

02 Sep '14

I do have here a Gentoo Linux and a KVM (Gentoo too) - now I'm wondering if I can just emerge the Gentoo Tor package here in the KVM and play with it or should I prepare few things before to avoid that it will be used by the Tor network immediately ? -- Toralf pgp key: 0076 E94E

Hi, The key from deb.torproject.org archive is expired, a new one would be nice. The installation information in the docu should be updated to the new key id as well.

Authdir is rejecting routers in this range
by Davíð Steinn Geirsson 30 Aug '14

30 Aug '14

Hi all, I rented a dedicated server to run a tor relay (100Mbit/s) to contribute to the network. On this machine, tor gives messages like these on startup: http status 400 ("Authdir is rejecting routers in this range.") response from dirserver '<...>'. Please correct. The server is hosted with https://fdcservers.net/. Did I just get unlucky in picking a provider? Is there a way to check these things before spending money on setup + monthly fees? Best regards, Davíð

Key expired problem - Ubuntu 12.04 LTS

I'm experiencing difficulties running apt-get update as it complaints that the repository's key is out of date. Here's the error: W: A error occurred during the signature verification. The repository is not updated and the previous index files will be used. GPG error: http://deb.torproject.org precise Release: The following signatures were invalid: KEYEXPIRED 1409325681 KEYEXPIRED 1409325681 KEYEXPIRED 1409325681 KEYEXPIRED 1409325681 W: Failed to fetch http://deb.torproject.org/torproject.org/dists/precise/Release W: Some index files failed to download. They have been ignored, or old ones used instead. When I set the relay up, I used Option Two on this page https://www.torproject.org/docs/debian to install tor and deb.torproject.org-keyring . Updates worked for 10 weeks or so and now don't. I've tried going through the same processes again, to no avail. Any assistance very gratefully received.

There are no packages for centos 7 yet. Is there an ETA? Is there anything we can do/contribute?

To clarify, because the nodes are physically close to one another, they are in the same /24, namely x.x.x.x - x.x.x.y. Yes, the real issues is the traffic concentration to a specific set of routers, which is why I'm asking. I'm trying to get a sense of where to draw the line, but from the responses so far it looks like I've got room to spare. - -- Jesse V. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.14 (GNU/Linux) Comment: Using GnuPG with Thunderbird - http://www.enigmail.net/ iQF8BAEBCQBmBQJT/lfPXxSAAAAAAC4AKGlzc3Vlci1mcHJAbm90YXRpb25zLm9w ZW5wZ3AuZmlmdGhob3JzZW1hbi5uZXQxMjgyMjhENjEyODQ1OTU1NzBCMjgwRkFB RDk3MzY0RkMyMEJFQzgwAAoJEK2XNk/CC+yAYCwH/i6Ci/SS6dpXr703mlajr31C fXX2WOKVWoGGTkPDXkQJM18+uI0DGRaieahmQ99VAGwA8+PAFhq9QsISLZ/Bby9g rZCOkY9E9xel2uu80hiMlP99h4WkjJtbgeX1cGXXOoJq1d+MLHIzQqgzZvmVry2+ piIUsXRO693r+TiU6BzZjnpBm+Omo6BzvOuJmUq34/XztdrGWSfoCvpwlesbMJZc sNGN1N5wQ3U1FcQTkwJc2wVyTpQNyu+tgvZyqwusIwAlH7J9cN/zg+eNZ+3ZpPUv 7DjiKhwQCQUqv/LHC5sK7FmQNELLwXPGvTaflvjfhF9uSBWCAX9JVEBNsHrB1M0= =77pe -----END PGP SIGNATURE-----

The nodes are in the same /8 block and are physically close to one another as well. Is there any advantage in turning one of the relays into another exit? This is something that my ISP would be agreeable to, but I'm also pondering the effects on the Tor network as a whole. > Just want to be clear here: Do you really mean /8 and not /24? There's > only one university I can find with a /8 block. Anders, no I literally mean the same /8. The university has its own /16 and recently required another /16, but since my nodes are physically close to one another they are in the same /8. My concern is that too many nodes in a small block can result in a large concentration of Tor circuits in that block. No circuit should use any two nodes from the same /16 unless forced to, so my question really revolved around how many is too many Tor circuits and how much is too much traffic through the same /8 or /16 in people's opinion. - -- Jesse V.

I'm aware that no circuit should contain two nodes from the same /16 unless forced to, and the MyFamily value further helps with that. My concern was not with a single circuit using multiple nodes there, but rather many circuits preferring that AS. Diversity helps security. That being said, by your advice I'm nowhere near that threshold, so I could keep going. Thanks for the tips on the multiple Tor instances and the optimization tips. - -- Jesse V. /CS, Network Security / -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.14 (GNU/Linux) Comment: Using GnuPG with Thunderbird - http://www.enigmail.net/ iQF8BAEBCQBmBQJT/e7iXxSAAAAAAC4AKGlzc3Vlci1mcHJAbm90YXRpb25zLm9w ZW5wZ3AuZmlmdGhob3JzZW1hbi5uZXQxMjgyMjhENjEyODQ1OTU1NzBCMjgwRkFB RDk3MzY0RkMyMEJFQzgwAAoJEK2XNk/CC+yAu0wIAK3rn17vEWQZTZy5KVBgOnUI TstJAkqO9Wjkfxf++E/5h8OMRdU1f3rV2mArJgGbgc344ttueM8iPntneaK4jI9W 4FrEqiMf7X6boYZXyeG81gYaGT6nf8ePSK5+1xY3pGR+2R3gXbDt/AU/LIZFsL2w r+9znukltzWBudfM76Fzd7jJcrwC+2giguHKU1/oxpKDh1xWuQC4maOYxZexGSLw JFz/O9Ca/CIDH/5Pbm6uJFe3Ec1zzm6z8cgsfBmGY8GHj3xBM8bNttP+a+fW7J5Z W01uoYss6tuw3jhVAp/+LKm4GcXsdtUjJIAX56yvEURCa6L9CbuTYha4cBI4zFw= =OHSc -----END PGP SIGNATURE-----

Ongoing scan from FDCServers block
by linenoiz＠Safe-mail.net 27 Aug '14

27 Aug '14

For the past week or so I've been seeing unsolicited echo replies coming from FDC servers block and one that looks like it is owned by China(?) Most of the entries are from 67.159.54.101 and I am seeing around one per minute. I verified by running tcpdump for a couple minutes (no longer, I'm not an illegal wiretapper!) that I'm not sending echo requests. IPTables is configured to drop and log this invalid traffic. Any idea what they are trying to accomplish? Some convoluted way of pinging me because they don't get an ICMP unreachable back? And why every minute?
