Help collect hidden service usage stats?
by Roger Dingledine 24 Sep '14

24 Sep '14

Hi folks, If you are comfortable compiling Tor from git, and you want to help investigate what fraction of Tor network load comes from hidden service use, I have a shiny new git branch called hs-stats that will collect per-thirty-minute statistics about number of circuits and number of cells your relay sees that have to do with exiting, with hidden services, with circuits where you're not the final hop, and a fourth none-of-the-above category. https://trac.torproject.org/projects/tor/ticket/13192 It skips all circuits and cells that come from non-relays, which should help make sure the stats aren't useful for hurting anonymity. It doesn't automatically send the output anywhere -- it just writes it to its notice-level log for now. So you'll need to either send me the log lines, or add them to the trac ticket like I did here: https://trac.torproject.org/projects/tor/ticket/13192#comment:2 Preliminary results are that load from hidden services is actually a tiny fraction of overall load. A bonus use from these statistics would be to learn what fraction of load comes from exit connections vs middle connections, for relays with various consensus flags. And of course, it's possible there are bugs in how I'm doing the counting. I'll keep investigating to make sure I'm doing it right. Thanks! --Roger

How about a TWN entry about hosting locations?
by Jens Kubieziel 24 Sep '14

24 Sep '14

Hi, it seems quite much work for a person to collect information about hosting locations. So what do you think about putting a section into next TWN which links to a wiki page where everyone can share information about costs in different regions? -- Jens Kubieziel http://www.kubieziel.de Es genügt nicht, keine Gedanken zu haben. Man muß auch unfähig sein, sie auszudrücken. Karl Kraus

A friendly reminder for all ScrambleSuit bridge operators.
by Yawning Angel 24 Sep '14

24 Sep '14

Hello all, This is a friendly reminder to all ScrambleSuit bridge operators that unless you are running tor-0.2.5.x, you should not be running a ScrambleSuit bridge. This is because the method for propagating the ScrambleSuit password (or any other future pluggable transport server side argument) for inclusion in the Bridge line served from BridgeDB was implemented in 0.2.5.x, and is not present in 0.2.4.x, and to make matters worse, 0.2.4.x has a bug that will allow this configuration to run instead of failing with an error[0]. If you are running a ScrambleSuit bridge with tor-0.2.4.x, it is useless. Users that happen to be served your ScrambleSuit bridge will not be able to connect, because the password is missing. Approximately 1/7th of the ScrambleSuit bridges in BridgeDB exhibit this behavior and we will most likely start filtering them on the BridgeDB side. Please see https://trac.torproject.org/projects/tor/ticket/13202 if you wish to know more about this. Best Regards, -- Yawning Angel [0]: Apparently this is not worth patching 0.2.4.x for, which I personally view as unfortunate.

I assume the distribution of authorities is similar. Apart from China, no Asia-Pacific country makes the top 20 in Tor compass.[1] And no southern hemisphere country makes the top 20 at all. The first Asia-Pacific countries after China are Japan at #29, then Singapore at #37. And unless I've missed something, the first southern hemisphere country is Australia at #42. Details aside, I'd love to see more routers and exits in countries other than the top 4 (Germany, France, Netherlands, United States). This helps spread failure risk, sovereign risk, and the risk from 3 letter agencies and the like. And it would make Tor faster for those in the southern hemisphere, Africa, and the Asia-pacific. But I don't know how much hope there is for this - I've tried to find pricing in Australia, and the figures I've found are: $8000 per month for 100Mbps.[2] $1500 per month for 25Mbps.[3] $800 per month for 10Mbps.[4] That seems ridiculously pricey… I'd rather wait for the National Broadband Network and run one on 100Mbps fibre at 1% of the price.[5] (Except bandwidth would not be guaranteed on a "home"-style plan.) Time to find a sympathetic university?

I've updated the list of good/bad ISPs. It shows relay [ ] exit [ ] in front of every good ISP. Please verify that information is accurate. Special information, like anonymous hosting, would be appreciated. Thanks

Correctly setting up arm
by Chris Whittleston 23 Sep '14

23 Sep '14

Dear all, Previously, I've run arm using 'sudo -u debian-tor arm'. As was mentioned here previously, this is not how you should run it - in fact there is a bit of documentation to suggest how it should be done. Unfortunately I'm having some issues getting arm working correctly as described here in step 14: https://www.torproject.org/docs/tor-relay-debian.html.en#after Having added my user (pi) to the debian-tor group, I try to run 'arm' and get the following: Failed to read authentication cookie (permission denied): /var/run/tor/control.authcookie I've tried reinstalling arm, relogged and checked that I'm in the right group still using 'groups' (which I am) - no joy. I've checked my torrc and found the following lines: ## If you enable the controlport, be sure to enable one of these ## authentication methods, to prevent attackers from accessing it. #HashedControlPassword 16:872860B76453A77D60CA2BB8C1A7042072093276A3D701AD684053EC4C #CookieAuthentication 1 CookieAuthentication wasn't initially enabled, turning it on makes no difference, I get the same error. I am able to get it working when setting up HashedControlPassword by generating a has using tor --hash-password <password> and editing torrc accordingly. Am I missing something when it comes to setting up CookieAuthentication? I guess I must be...although it seems strange that I was getting that error even with CookieAuthentication disabled. Any insight appreciated :) Chris -- *Dr Chris Whittleston 栗主* Department of Chemistry University of Cambridge Lensfield Road, Cambridge, CB2 1EW Email: csw34(a)cam.ac.uk Tel: +44 (0)1223 336423

help with getting CentOS 5
by I 23 Sep '14

23 Sep '14

Hej, Following the installation on CentOS instructions on https://www.torproject.org/docs/rpms.html.en it appears there is no package for CentOS 5 only 6 and 7. "http://deb-master.torproject.org/torproject.org/rpm/el/5/i386/repodatarepom…: [Errno 4] IOError: <urlopen error (110, '\xe8\xbf\x9e\xe6\x8e\xa5\xe8\xb6\x85\xe6\x97\xb6')> " Could someone tell me whether CentOS 6 version can be used on CentOS 5?

Mac OS X configuration problem(s)
by Surf Norway 23 Sep '14

23 Sep '14

I've installed the tor package via homebrew, and cofigured /usr/local/etc/tor/torrc according to the documentation. My problem is that every time I try to use launchctl I get an error, both as an admin user and via sudo. As an admin user: Could not open job overrides database at: /private/var/db/launchd.db/com.apple.launchd.peruser.502/overrides.plist: 13: Permission denied launch_msg(): Socket is not connected When run via sudo it complains about "dubious owbership on file" and says "nothing found to load". I followed whatever documentation I could find. The torrc config is on torproject.org under "configuring a relay graphically" (I know this isn't graphically), the homebrew info is linked to in the same article and looks to be from a mailing list discussion. I wanted to set up a simple relay to run automatically when the (OS X) machine boots. It's a home server on a 30MB/sec symmetrical fiber line. Since I run the machine as a file server anyway, I figured I could allocate some bandwidth and help support the community. Thanks, Surf Norway
