Wouldn't it be possible to code the Tor clients to not build circuits using relays in the same /24 or with "similar" names? While that wouldn't fix ALL possible attack scenarios, that could certainly help, and help against accidental (or malicious) misconfigured nodes.

Probably just misconfigured. If there are emails attached to the nodes you could try mailing them directly about it. brwyatt On Fri, 6 Jan 2012 01:29:42 +0100, "Aurel W." <aurel.w(a)gmail.com> wrote: > Hi, > > when I browse through the list of relays I find many router names, > which correlate in some way, but which don't specify a family in their > descriptors. > > Just to name a few: > * 2* c5VycfOP > * 3* c516a > * Caldron, Caldron2, Caldron3 > * BlgTOR2, BlgTOR > * DwarfHappy, DwarfSleepy, DwarfSneezy, DwarfDopey > * DONATIONxTORx0 - DONATIONxTORx7 > and so on,... > > is there a reason, why there is such a high number of relays, which > fail to specify a family, since this seams rather striking? > > aurel > _______________________________________________ > tor-relays mailing list > tor-relays(a)lists.torproject.org > https://lists.torproject.org/cgi-bin/mailman/listinfo/tor-relays

Internal server error while fetching from dizum
by Klaus Layer 09 Jan '12

09 Jan '12

Hi, my relays are getting 500 error while fetching data from authority dizum. Can someone explain what is happening with this tor authority? Regards, Klaus 14:25:51 [WARN] Received http status code 500 ("Internal Server Error") from server '194.109.206.212:80' while fetching "/tor/server/d/C539CB98343680892C46D0A70770E6D0A4A39564+E5A7994519731C2C3349AAA4C2A38CED2CE74457+E8507D31268490E9E4E8A2110E371F1537156C75+E8BCD670FFB8ADF73195BDB9362ACDDB28F704A5+E94B92087B4614CB7F1C9CC1191C383- 7D890C60E+EA71B375FC45F026C854C903887D981CF19B7326+EA9DE146A13B316D2F3D5C2ACF491C068B93FF9D+EB896E11C16C0531D83560D3CBBEF97AF2FFF4D5+ECEBAAF01CA177EEB68A8A6838E4A16- BD54749F6+ED5A60237FDCA188DF30DC380536754DFBF01404.z".

consensus update request

08 Jan '12

The last consensus document expired about 15 hours ago. I understand that the authority operators and tor developers are probably occupied with fixing whatever is the trouble, but if someone in that group of individuals can spare a moment to fill us in on what is happening, I, for one, would greatly appreciate it. FWIW, I think a page on the torproject.org web site for very brief status updates on extraordinary situations like this one would be a good and helpful addition. Thanks much, and best of luck getting things working right again. Scott Bennett, Comm.

Relay vs. bridge: difference in traffic?
by Steve Snyder 05 Jan '12

05 Jan '12

Can someone tell how being a bridge compares to being a regular exit node in terms of traffic? I can see how there would less traffic as a bridge since the node isn't advertised. On the other hand, there are many fewer bridges than regulat nodes so maybe the traffic on a given bridge is greater? Thanks.

not specified families
by Aurel W. 05 Jan '12

05 Jan '12

Hi, when I browse through the list of relays I find many router names, which correlate in some way, but which don't specify a family in their descriptors. Just to name a few: * 2* c5VycfOP * 3* c516a * Caldron, Caldron2, Caldron3 * BlgTOR2, BlgTOR * DwarfHappy, DwarfSleepy, DwarfSneezy, DwarfDopey * DONATIONxTORx0 - DONATIONxTORx7 and so on,... is there a reason, why there is such a high number of relays, which fail to specify a family, since this seams rather striking? aurel

I'm showing that tor is currently using 12 - 14 Mbps on my relay, however, the status page for my relay ( http://torstatus.blutmagie.de/router_detail.php?FP=192bdf2831c1b007a08dc3c1… ) does not reflect this speed. Is there a reason for this? Nick

Received botnet/drone abuse complaint
by Steve Snyder 03 Jan '12

03 Jan '12

I received a botnet/drone complaint from shadowserver.org today (delayed due to holidays) regarding my exit node: timestamp ip port type infection cc cc_port 12/29/2011 19:52 173.208.132.210 48586 32097 US MISSOURI KANSAS CITY tcp mebroot ukixxuug.com|MAOS/0EC20201 14DF137A55320641 84.163.151.128 80 3320 DE 1 If I'm reading this correctly, they identify "mebroot" as the source of the problem. As this is a Windows MBR trojan it obviously doesn't apply to my Linux system. I scanned my system anyway and found no unexpected processes running. My DirPort is set to 80, which may explain that value in the complaint. Any thoughts on what to do to avoid further complaints? Shadowserver addresses the topic of Tor exits here: http://www.shadowserver.org/wiki/pmwiki.php/Involve/TORNodesAndReporting Thanks.
