Authdir is rejecting routers in this range
by Davíð Steinn Geirsson 29 Aug '14

29 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

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

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----- [View Less]

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 … [View More]

managing bandwidth quotum
by Kees Goossens 26 Aug '14

26 Aug '14

Dear all, A question on how to manage a bandwidth quotum of my internet provider. I run a non-exit relay on a hosted server with 1000 GB bandwidth per month. In essence, should I A- only set the AccountingMax, and let the relay figure out the RelayBandwidthRate & RelayBandwidthBurst by itself B- set the AccountingMax, and set RelayBandwidthBurst to whatever the provider will allow (much higher than the average rate) C- set the AccountingMax, and set RelayBandwidthRate to the average rate … [View More]

Advantage in more exits in the same /8?
by Jesse Victors 26 Aug '14

26 Aug '14

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA384 Hey everyone, I run some relays and an exit in a university setting. 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. It seems to me that too many nodes under the same ISP is problematic because it concentrates too much … [View More]

how long till the axe falls on little guard relays?
by starlight.2014q3＠binnacle.cx 25 Aug '14

The guard status of the relay here is hanging on by a thread (consensus 5-in-favor 4-against) and this had me wondering until I read [tor-relays] don't worry (to much) if your relay is loosing the guard flag https://lists.torproject.org/pipermail/tor-relays/2014-July/005043.html Looking at the Consensus Health page it's clear that about 1000 other relays are also separated from Guard Oblivion by a single vote. I'm curious if anyone knows roughly when the next authority will … [View More]
