Tor Software Update Question
by Keifer Bly 24 May '18

24 May '18

Hello, So I just updated the tor software using command “brew upgrade tor” on macOS. It upgraded from tor 0.3.3.0 to tor 0.3.3.6. I am wondering, do I need to restart my relay after doing this? I am also wondering, I have this email address in the “ContactInfo” in my torn file for tor project to contact me regarding issues with my relay, etc, but am wondering if there is a way to have this email for them to contact without displaying it publicly on my relay? Thank you very much.

Verizon AS701 blocking Tor consensus server tor26 (86.59.21.38)
by Neel Chauhan 24 May '18

24 May '18

Hi tor-relays mailing list, I have noticed that the Tor consensus server tor26 (https://metrics.torproject.org/rs.html#details/847B1F850344D7876491A54892F9…) is blocked on Verizon's UUNET (AS701) backbone, and therefore, Verizon's retail services like FiOS and Wireless. I can confirm this on FiOS, but I don't use Verizon Wireless (my smartphone uses Sprint) so I can't test it there. A traceroute to tor26's IP address 86.59.21.38 from a Brooklyn apartment shows this is filtered on Verizon's backbone: neel@xb2:~ % traceroute 86.59.21.38 traceroute to 86.59.21.38 (86.59.21.38), 64 hops max, 40 byte packets 1 unknown (192.168.1.1) 1.128 ms 0.780 ms 0.613 ms 2 lo0-100.NYCMNY-VFTTP-401.verizon-gni.net (173.68.77.1) 1.001 ms 3.632 ms 0.900 ms 3 B3401.NYCMNY-LCR-22.verizon-gni.net (100.41.137.96) 2.291 ms B3401.NYCMNY-LCR-21.verizon-gni.net (100.41.137.94) 3.172 ms 4.046 ms 4 * * * 5 * * * 6 * * * 7 * * * 8 * * * 9 * * * ^C neel@xb2:~ % In a normal traceroute, you will see ALTER.NET at hop 5.

It's also possible that Verizon could be doing it because the FCC repealed Net Neturality, and wants to discourage use of Tor to mine FiOS/VZW customers' browsing habits. But despite a NN repeal I can still access Tor on FiOS, and also run a relay (I do both) because other consensus relays are still unblocked. But if Verizon didn't unblock tor26, could it actually mean that Verizon wants to discourage Tor (and VPN/proxy) use to try to mine information of their customers (and sell ads/information) and direct users to VZ-owned AOL and Yahoo? Well, I hope they were just sloppy and don't mean to wage war on Tor. While I'm not saying you should avoid using anything Verizon at all costs (I certainly wouldn't want to go to the local cable company), I just want to point out a blocked consensus server.

Hi all, I have set up a tor relay on my Ubuntu machine by following the instructions given in the link <https://trac.torproject.org/projects/tor/wiki/TorRelayGuide>. To confirm whether the setup was done properly, I checked the status using the command: $ sudo service tor status and was getting status as "Active". Further, I looked into the log file /var/log/tor/notices.log using the command: $ tail -f /var/log/tor/notices.log and following was the output: May 24 18:24:54.000 [notice] Starting with guard context "default" May 24 18:24:54.000 [notice] Bootstrapped 80%: Connecting to the Tor network May 24 18:24:54.000 [notice] Signaled readiness to systemd May 24 18:24:55.000 [notice] Guessed our IP address as x.x.x.x (source: 204.13.164.118).

Re: [tor-relays] tor-relays Digest, Vol 88, Issue 41

Hi Jonathan, Thank you for offering your support. Yes, you are absolutely right.The exact problem which I was facing was that, I wasn't able to find the "Self-testing" line in /var/log/syslog file. I followed the instructions as told by you and I'm mentioning their results as well below. 1. I executed the command: $ sudo systemctl status tor I got the following output: [image: tor status.jpg] 2. I checked whether there was an issue related to permissions for the command: $ cat /var/log/syslog I figured out that there wasn't any error running that command (although I'm not attaching the output of that command). I am still not getting that "Self-testing" line in /var/log/syslog, which is the problem I'm facing specifically. It would be of great help if you can think of any other possible issue because of which I am facing this problem.

This config doesn't work, and that's a bug: https://trac.torproject.org/projects/tor/ticket/26136 >does a command utility or method exist for querying dirport documents via tunnelled-dir-server? including miscellanous documents such as > >/tor/status-vote/current/consensus.z … Stem master supports ORPort endpoints in stem.descriptor.remote.Query requests: https://stem.torproject.org/change_log.html There might not be convenience functions for some of the document types you listed, so you'll need to pass their paths in the resource argument. You might also want to avoid compression locally by dropping the ".z". There don't seem to be any examples of ORPort endpoints in the Stem repository. I think Dave plans to add some more documentation as part of Tor Summer of Privacy. T

Setting up tor relay
by Yash Kumar 23 May '18

23 May '18

Dear all, I want to setup my machine as a tor relay. I am using Ubuntu 16.04 LTS on a Intel i5 processor with 4 GB of memory. I followed the instructions given on this link <https://trac.torproject.org/projects/tor/wiki/TorRelayGuide>, but was getting some issue. In one of the later steps, it says "Verify that your relay works". This is done by checking my logfile(syslog) contains the following text: "Self-testing indicates your ORPort is reachable from the outside. Excellent. Publishing server descriptor." I checked the syslog by the command: $ cat /var/log/syslog To bring it to your knowledge, I have followed all the previous steps mentioned on that link <https://trac.torproject.org/projects/tor/wiki/TorRelayGuide>, and was successfully able to execute all the commands. I would request you to please help me out in setting up my machine as a relay to make tor network faster and more usable. Thank you, Yash Kumar

tor enters uninterruptible sleep forever when using transparent proxy
by Nicolás Dato 23 May '18

23 May '18

Hello there, First thanks for reading! I've been running a tor relay for almost two weeks from my home. Yesterday,* I did some upgrades to my Slackware 14.2 including glibc and kernel*. I run tor there and it worked fine. After upgrading Slackware I had to reboot and run windows for the night. Windows messes with the machine time. Today, *I rebooted and run Slackware and (as usual after running windows) *the clock was -3 hours apart. I do run NTP but looks like it doesn't make the adjustment if the difference is way too big. I adjusted the time and run the NTP service again. *Tor daemon launches at startup* so it was running when my clock was -3 hours from present time. I use irssi (IRC client) connecting to the tor transparent proxy using iptables. As usual, I runned irssi and tried to connect to a server but the connection hangs forever and tor hangs forever too, hanging the relay too. I tried a different server but hangs too. *Before trying to connect with irssi, this works:* The tor relay works fine and accepts connections and delivers traffic. I can run nyx and it connects fine and shows me the stats. I can connect to the socks proxy and it works and doesn't hangs tor daemon. After trying to connect with irsse, *all of that stop working.* I didn't changed any tor configuration neither the iptables configuration I did build the tor packages (recompiling it) and installed it, but didn't work I removed some files and folders from /var/log/tor, only removed the ones modified yesterday and today, but it didn't work neither. tor is reported by ps to be on uninterruptible sleep 1347 ? Dl 0:06 11 0 491216 87432 2.2 /usr/bin/tor and there is no way to kill it other than rebooting, neither kill -9 as root works after all the reboots, after removing some /var/lib/tor files, and having the machine clock on time, tor still hangs when using the transparent proxy this are the last lines from the debug log: https://paste.debian.net/plain/1025878 (that's from the time I tried to connect to freenode and it hanged, no more logs after that) this is my iptables: http://paste.debian.net/plainh/c949bc2a (irssi runs as ircuser) this is my torrc: http://paste.debian.net/plain/1025881 (I didn't copy some lines) Thanks again for reading.

Running a bridge remotely
by Keifer Bly 22 May '18

22 May '18

Hello, I have been running my home computer as a public tor relay for some time now with no issues, and unfortunately do not have a data center or anywhere else to run my relay from. I have noticed that there are far fewer bridges (about 2,000) then there are relays (about 7,000). As I have been running my home computer as a relay since last year, my ip address has already been in the tor network for a while, and thus will already be known as a relay to begin with. Is there a free way that I could remotely run an obfuscated bridge as well? I would need a way to do this remotely as I said my only available network ip has been on the public tor network for a considerable while.

DirPort DOS activity against Fallback Directories
by starlight.2017q4＠binnacle.cx 22 May '18

22 May '18

Recently I noticed excessive DirPort requests to my relay, where DirPort bandwidth reached 15% of ORPort bandwidth. Normal DirPort load is around 2%. https://lists.torproject.org/pipermail/tor-relays/2018-May/015253.html Just looked over a sample of FallBackDir relays in Relay Search and it appears this excess-load abuse is directed at them in particular. Some fall-back directories show more than a month of excess request traffic, presumably on the DirPort. Logs here indicate six weeks of abuse escalating in increments. Possibly this foreshadows a major increase in an effort to impair FallBackDir relay functionality. Either an iptables connection-rate limit or disabling DirPort resolves the problem.
