Re: [tor-relays] Considering setting up an exit, need advice

Thanks again guys for the help. "usuexit" is now online, and should be functioning properly, but there seem to be a few mystifying issues: 1) TorStatus marks it as "hibernating" which it clearly isn't; it's online and accepting connections. I'm not sure what made TorStatus think it was offline. 2) For the first nine hours it has moved about 12 MB of data. I would think it would be more than that, especially for an exit. There's a blog post outlining the growth rate for guards, but how about for exits? 3) There are mysterious warnings in the log: Jan 30 21:57:36.000 [notice] Circuit handshake stats since last time: 0/0 TAP, 50/50 NTor. Jan 30 22:57:36.000 [notice] Circuit handshake stats since last time: 0/0 TAP, 31/31 NTor. Jan 30 23:07:29.000 [warn] EXTEND cell received, but not via RELAY_EARLY. Dropping. [4 similar message(s) suppressed in last 3600 seconds] Jan 30 23:07:29.000 [warn] (We have dropped 95.24% of all EXTEND cells for this reason) Jan 30 23:57:36.000 [notice] Circuit handshake stats since last time: 0/0 TAP, 39/39 NTor. Jan 31 00:01:41.000 [warn] Got headers "HEAD / HTTP/1.0\r\n\r\n" with unknown command. Closing. Jan 31 00:57:36.000 [notice] Circuit handshake stats since last time: 2/2 TAP, 41/41 NTor. Jan 31 01:04:46.000 [warn] EXTEND cell received, but not via RELAY_EARLY. Dropping. Jan 31 01:04:46.000 [warn] (We have dropped 95.45% of all EXTEND cells for this reason) I'm familiar with the meaning of the "EXTEND" cell, but I'm not sure what RELAY_EARLY is, nor do I know what this warning means. If the relay has an exit policy, why are circuits being extended beyond it? Hidden services, maybe? Basically the log has more warnings in it than it should (at least based on my experience with regular relays) and I'm not sure why. I tried restarting Tor, but the warnings still appeared. Any ideas on what I can do about them, if anything? Thanks, Jesse

Using syslog for monitoring bridges
by Andreas Fritzel 30 Jan '14

30 Jan '14

Hey all, In two different countries I run 3 Tor bridges for a while now. For monitoring, I want to quit using the local filesystem for storing files, filled by syslog and be able to store the syslog info on a remote system. This is done easily with rsyslog[1], but I want to store it at home without the link between the three bridges and my home IP. So, I was thinking about sending it with rsyslog over TCP to a Tor Hidden Service. Is there anyone who can help me out with this? I was thinking about using SOCKS, but it didn't work out :(.

Problems with domestic ISP blocking publicly listed relays
by Paul Blakeman 28 Jan '14

28 Jan '14

Hi all Wondered if anybody could help out/advise as to what’s happened here… I’m based in UK and have domestic internet with Virgin Media. This service is fibre optic based - config: 30Mbps d/l & 2Mbps u/l [mine is the SLOWEST package!] Last year I finally configured a Dell server (running Debian 7.3 - wheezy) to run a Tor relay (0.2.3.25) Everything has been running fine except for the last few weeks I’ve noticed a few irregularities. The first one has been Tor itself where I have noticed (using Arm to monitor) that it has been downloading far more data than uploading. A ratio of say 5:1 — it hasn’t always been this way! The other is my general difficulty in accessing certain web sites online (that once worked) e.g. Access to lovefim.com this weekend has now resulted in no longer able to stream and watch films. I can log onto system but if I try and stream I get the error message “INVALID LOCATION. Sorry, but the requested content is not available in your current location.” Opened a service desk ticket but the response was “you are trying to stream from outside the UK” WTF????? My IP provided by my ISP has been the same all this time (82.42.215.16) I have spoken with them I would have to switch off for 48hrs and MAY NOT (in fact I was told “probably not”) be assigned a different one! SO… Can using a Tor relay result in your IP getting a “bad” flag? Is there anyway of running a relay where you “hide” your IP? Any advise would be greatly appreciated. Best wishes, Paul

which browser for BSD systems?
by Scott Bennett 28 Jan '14

28 Jan '14

I'm about a year behind on reading this list, so in the event that my question has been addressed during that time, please forgive me for skipping ahead to the present. In the past week, I have *finally* managed to upgrade from FreeBSD 8.2 to 9.2 and am now slogging through the rebuilding of all my installed ports. The ancient version of firefox that I had been stuck with due to later versions' memory allocation bugs now no longer works. For the moment, I have built firefox 26, but because there is no longer a version of torbutton to be found for love or money from anywhere I'd trust, I'd really like to install something safer than just firefox with NoScript, AdblockPlus, Better Privacy, and a couple of other add-ons. The tor project's web site still has no browser available for the {Dragonfly,Free,Net,Open}BSD, so what I'd like to know is which browser and security add-ons can the tor community recommend for use with tor? Thanks in advance for any clues. Scott Bennett, Comm.

TTTT scoreboard
by Sebastian Urbach 28 Jan '14

28 Jan '14

Dear list members, The scoreboard mentioned above is now displaying the data from the first transmission ever made and from the last one ever made. Until a few hours ago it was just the data from the first run no matter what was done afterwards. This was a problem from the "we never expected multiple runs" era. It's kind of great that bugs are occurring because you are submitting data from multiple runs ;-) ! Please feel free to check it out: http://128.174.241.211:443/relay_scoreboard This is a project were literally every run counts. If you want to help, visit the project site and join us: http://web.engr.illinois.edu/~das17/tor-traceroute_v1.html It seems that there will be a data review in 03/2014, so it would be great to have enough data to actually draw some conclusions this time.

0.2.4.20 logging duplicate messages
by Scott Bennett 28 Jan '14

Along with my recent OS upgrade I have also updated my tor relay from 0.2.4.3-alpha to 0.2.4.20. The latter version write two identical copies of every message to the log file. I have only one uncommented "Log " line in my torrc, which is Log notice file /var/log/tor/notices.log but every single message is getting written to the file twice.

Considering setting up an exit, need advice
by Jesse Victors 28 Jan '14

28 Jan '14

Hello everyone, I'm thinking about setting up an exit here at my university here in the US. My ISP has no problem with Tor relays on the fast connections, but I haven't inquired about exits. I'd be running the exit on a surplus computer that I have control over in a lab in one of the main buildings. How do I ask my ISP about it? I'll be doing some research as to what ports I can open to contribute yet avoid being flooded by complaints, but if anyone has any tips I'd appreciate it. Would it be a good idea to copy the exit policy of the node at MIT? Is there a way to configure the Linux firewall so that only Tor has Internet access, in order to help show that I wasn't behind anything that comes out of the exit? I'm basically just looking to get started here if this is feasible, and looking for advice.

NTor handshake
by Sebastian Urbach 27 Jan '14

27 Jan '14

Hi, May i ask when the NTor handshake is going to be recommended by the majority of the directory authorities ? It's probably not a surprise that i prefer NTor handshake as a relay operator. I checked constantly since the switch to 0.2.4.20 and the values are pretty constant. (35k TAP / 700 NTor). I didn't notice any complaints so i assume that it should be possible to push forward. -- Mit freundlichen Grüssen / Sincerely yours Sebastian Urbach ---------------------------------------------- Those who would give up essential Liberty, to purchase a little temporary Safety, deserve neither Liberty nor Safety. ---------------------------------------------- Benjamin Franklin (1706 - 1790), Inventor, journalist, printer, diplomat, and statesman

To anyone whom might give a suggestion or answer.
