Relay down, "rejected", help
by kbesig 30 Apr '14

30 Apr '14

My relay became one of the "rejected" since the heartbleed vulnerability surfaced so I reformatted my XP relay and did a fresh Ubuntu 14.04 LTS install. Built vidalia-0.2.21 from source using: deb http://deb.torproject.org/torproject.org trusty main deb-src http://deb.torproject.org/torproject.org trusty main apt-get install build-essential fakeroot devscripts qt4-dev-tools qt4-designer libqt4-dev g++ cmake apt-get build-dep vidalia mkdir ~/debian-packages; cd ~/debian-packages apt-get source vidalia cd vidalia-* debuild -rfakeroot -uc -us cd .. sudo dpkg -i vidalia_*.deb Edited /etc/tor/torrc allowing connection ports. I'm unable to open vidalia with these error messages: 1. As non-admin: /usr/bin/vidalia (process:540): GConf-WARNING **: Client failed to connect to the D-BUS daemon: An AppArmor policy prevents this sender from sending this message to this recipient, 0 matched rules; type="method_call", sender="(null)" (inactive) interface="org.freedesktop.DBus" member="Hello" error name="(unset)" requested_reply="0" destination="org.freedesktop.DBus" (bus) (<unknown>:540): GLib-GIO-ERROR **: No GSettings schemas are installed on the system Trace/breakpoint trap (core dumped) 2. As root: /usr/bin/vidalia No protocol specified vidalia: cannot connect to X server :0 3. As root: /usr/bin/X11/vidalia No protocol specified vidalia: cannot connect to X server :0 I've seen similar errors searching for a fix, but none that seemed "resolved". Any suggestions would be appreciated as I'd like to get back up and running ASAP Thanks ------------------------------------------------------------------------

MaxAdvertiseBandwith
by jchase 30 Apr '14

30 Apr '14

Hi, I have a non-exit relay running Tor 0.2.25 on a Pi. Consensus weight 37. exit-policy: reject *:* Now Iḿ back from vacation and my relay has 1600 incoming conncts and arm warns me that my bandwidth is too small to support so many incomers. Would I kindly restrict my reject policy or limit my MaxAdvertiseBandwidth. Which I believe is no longer supported(?). Can anyone help me cut down on the traffic and the notices? J. Chase

can the old compromised keys be invalidated, "named" be recovered
by starlight.2014q2＠binnacle.cx 29 Apr '14

29 Apr '14

I just read that the relay can't get its old name back for six months now that the keys have been changed due to Heartbleed. Does any way exist to invalidate the old keys and transfer the name to the new relay? I realize that naming a relay is strictly an exercise in vanity, but hey, who is entirely immune?

Compiling tor-0.2.5.3-alpha on Raspberry Pi
by Lance Hathaway 29 Apr '14

29 Apr '14

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA512 Apologies if this would be better addressed in a different list... I know there are a couple of people here who are working on making the Raspberry Pi a good option for running Tor--and the work is appreciated! Gordon Morehouse has built binary pickages for the Pi, but I wanted to try compiling it myself (for good practice, mostly). I followed the directions for compiling from source on a Debian-based system, but the compile fails with the following: config/parse_bridge_line: FAIL ../src/test/test_config.c:373: a.b.c.d was supposed to fail, but it didn't.

Have I overlooked something stupid? I don't want to open a "bug" unless it's an honest-to-goodness bug (developers have better things to do with their time than chase down "bugs" which are actually "user errors"), but I don't have the knowledge to say whether this is a bug or not...

Help setting up an exit relay on CentOS linux
by Chuck Bevitt 28 Apr '14

28 Apr '14

Hello all, I've run an exit node from my home in the past using my consumer ISP service (Time Warner) and Windows 8, I'm pretty much of a Windows guy (I make my living building business applications with Microsoft tools) but now I have an opportunity to run an exit node on a hosted server running CentOS linux. I've loaded CentOS at home to test it out and the problem I'm having is that I can't get the Vidalia control to run. The browser bundle works OK - I can open FireFox and make a Tor connection. As far as I know I've downloaded the correct files for CentOS linux and I have the Vidalia start icon. However nothing happened when I try to open the Vidalia icon. Since I'm not familiar with linux, I don't know where to start looking. I had assumed that I would just open Vidalia and set up my exit relay the same way I did on Windows 8. I greatly appreciate help with this especially from someone who's configured a relay on CentOS. Thanks, Chuck Bevitt

Bridge Operators - Heartbleed, Heartwarming, and Increased Help
by Matthew Finkel 26 Apr '14

26 Apr '14

Hi All, Below is an email we sent last week to almost all of the bridge operators who provided contact information for their bridge(s). For those operators we missed and for those we couldn't contact, this hopefully provides some useful information. All the best, Matt ----------------------------------------------------------------------- Hi Tor Bridge Relay Operator! Unfortunately this email must begin with bad news, but it gets better. Due to the recent Heartbleed OpenSSL vulnerability that was disclosed earlier this week, we are reaching out to you to ask that you install an updated version of OpenSSL. The vulnerability has the potential to decrease the security of your bridge as well as the anonymity of any user connecting to your bridge. As a result of this, we also ask that you generate a new identity key due to the possibility that your current one was leaked. The process to upgrade your version of OpenSSL depends greatly on your operating system. Please ensure you are using a version that was released within the past four days, see the Heartbleed website[0] for more details on the vulnerability and for which versions are affected. Please do this before you regenerate your identity key. When this is done, you will need to restart Tor. At this point you can ask us to retest your bridge to confirm that it is not vulnerable anymore. Next, to regenerate your identity key simply stop Tor and delete the current key. This is done by opening Tor's Data directory and removing the contents in the keys/ directory. Tor's Data directory is located at /var/lib/tor, by default. Let us know if you have trouble locating it. When this is complete, start Tor and it will automatically create a new identity for you. See the recent blog post for many more details: https://blog.torproject.org/blog/openssl-bug-cve-2014-0160 Now that the bad news was said, we want to take this opportunity to thank you, from the bottom of our hearts, for volunteering to run a bridge relay. We know we do not say it often, but it is really appreciated! Please let us know if you have any question, concerns, or suggestions, especially related to how we communicate with you and how bridge relay operators can be more involved. Lastly, if you are not already running the obfsproxy pluggable transport[1] (i.e. obfs3) on your bridge, please follow the Debian instructions[2] (for a Debian-based system) on the website and install it. Your bridge is a great contribution to the Tor network, however as censorship on the internet increases around the world users are forced to use a pluggable transport. Tor does not understand how to communicate with them by default, though. Therefore we are asking that all bridge operators install obfsproxy and help as many users as possible. In addition, also consider subscribing to the tor-relays mailing list[3], if you are not already; we will be posting instructions on how to maximize the contribution of your bridge on that list every now and then. [0] http://heartbleed.com [1] https://www.torproject.org/docs/pluggable-transports.html.en [2] https://www.torproject.org/projects/obfsproxy-debian-instructions.html.en#i… [3] https://lists.torproject.org/cgi-bin/mailman/listinfo/tor-relays Again, thank you for running a bridge relay and sorry for the bad news. Let us know if you have any questions or if you have any suggestions. All the best, Matt The Tor Project

Relay reading more than it writes??
by Rupert Roe 26 Apr '14

26 Apr '14

Hi All, I recently started running these two relays on raspberry Pis in the UK: http://torstatus.blutmagie.de/router_detail.php?FP=515a9887a426c1dc2bb4b9b1… http://torstatus.blutmagie.de/router_detail.php?FP=e3e6a7de02caa12ac5712884… Both of my relays seem to consistently read more from the network than they write, and I can't figure out why. Are my relays dropping loads of packets? If so is that harming the speed or reliability of the network? Why are my relays doing this when other ones seem to have a perfect read / write balance?? If anyone has any ideas why this is happening or how I could troubleshoot the issue I'd be really grateful! Thanks, Rupert

Please need urgent help with the DNS resolver of a fast exit relay
by s7r＠sky-ip.org 25 Apr '14

25 Apr '14

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 Hi, The servers from my ISP are not stable or good enough to handle the traffic for this Tor exit router. I get this in the log very often: Apr 24 15:14:07.000 [notice] Circuit handshake stats since last time: 91633/91636 TAP, 15962/15962 NTor. Apr 24 17:40:45.000 [warn] eventdns: All nameservers have failed Apr 24 17:40:45.000 [notice] eventdns: Nameserver <ip>:53 is back up Both nameservers fail and come back after 1 second, or less. I don't know what impact will this have on the exit node. Is it any problem at all? I have decided also to setup my own DNS resolver and not use the ones from ISP, so I have installed named. What I need help is, for your someone to tell me exactly how do i have to edit named.conf in order to: 1. Enable DNSSEC, for the clients who want to use it. Not make it a requirement, just enable it and prefer it over normal DNS if and when possible. 2. Be able to resolve all TLDs as described here: https://trac.torproject.org/projects/tor/wiki/doc/DnsResolver#DNSResolverSe… Now I can clearly understand the message from that post but there is no instruction anywhere about how to do it, those links for Alt Roots are broken. Is this a requirement? Who needs to resolve silly TLDs not supported by IANA / ICANN anyway? 3. Cache the records for as long as possible - my relay is already using a lot of traffic so I have to spare as much as I can. Please provide me with a good named.conf and description of settings so I can properly configure a good DNS resolver for my relay.

Exit node rejection of special IPv4 blocks
by Zack Weinberg 24 Apr '14

24 Apr '14

I'd like a sanity check on this list of special-purpose IPv4 blocks which I'm currently forbidding in the CMU exit node's policy. I'm most uncertain about denying access to multicast (224.0.0.0/4) and 6to4 router anycast (192.88.99.0/24) -- I *think* there are no scenarios where someone would actually need to get at either of those via Tor, but I could be wrong. # Reserved IPv4 addresses, sorted by RFC and then numerically reject 255.255.255.255/32:* # RFC 0919: "limited broadcast" reject 224.0.0.0/4:* # RFC 1112: multicast reject 240.0.0.0/4:* # RFC 1112: future addressing modes reject 0.0.0.0/8:* # RFC 1122: "This host" source address reject 127.0.0.0/8:* # RFC 1122: Loopback reject 10.0.0.0/8:* # RFC 1918: private use reject 172.16.0.0/12:* # " " " reject 192.168.0.0/16:* # " " " reject 198.18.0.0/15:* # RFC 2544: test environments reject 192.88.99.0/24:* # RFC 3068: 6to4 relay anycast (???) reject 169.254.0.0/16:* # RFC 3927: link-local reject 192.0.2.0/24:* # RFC 5737: documentation reject 198.51.100.0/24:* # " " " reject 203.0.113.0/24:* # " " " reject 100.64.0.0/10:* # RFC 6598: "shared space"/"carrier grade NAT" reject 192.0.0.0/24:* # RFC 6890: future special purposes TIA, zw

Bridges included in Tor Browser -- should they regen keys because of Heartbleed?
by David Fifield 23 Apr '14

23 Apr '14

I wondered whether operators of bridges that are included in the browser bundle should generate new identity keys after upgrading their OpenSSL. The argument for generating new keys is that old keys may have been compromised by Heartbleed. The argument against is that a new fingerprint will prevent existing browser bundle users from using the default bridges, because the fingerprint is built into the browser: https://gitweb.torproject.org/builders/tor-browser-bundle.git/blob/HEAD:/Bu… What I heard from some developers is that it would be good to set up new bridges with new keys (could be on the same IP address), and give the new information to the browser devs so they can put it in the bundles. Leave the old ones running for a while until usage drops off. A question is how to actually do this, running two copies of tor on the same IP. Offhand I would say that using a separate DataDirectory will be enough, but I don't know for sure. David Fifield
