Reminder: exit nodes probably shouldn't be using Google's DNS servers
by Nick Mathewson 25 Feb '16

25 Feb '16

Hi, all! While looking into a bug report, I noticed that an exit node was using one of Google's well-known public DNS servers for its own DNS server. No disrespect to the operators of Google's fine public DNS service, but my sense is that using it for a Tor exit node might not be the greatest idea for users' privacy, having one DNS provider that gets to see so many requests. It's probably a better idea to have your own local cacheing DNS server. Would anybody like to share a guide about how to set one of those up safely and migrate correctly? best wishes, -- Nick

Relay Consensus Weight
by Marco Morgia 24 Apr '15

24 Apr '15

Hello, on friday my realay's Consensus Weight felt down suddenly to 20 and the its bandwidth is not used anymore (https://atlas.torproject.org/#details/94212674A2C6AEBF77354D959D464E49BC878…). I don't understand why, as nothing is changed in its configuration. And, I don't know if it's related, but I noticed that the tor network has slow down in the last days and some times it's very difficult to use it.

Tor and Freenode
by Markus Hitter 20 Apr '15

20 Apr '15

Hello all, after yesterday watching "State of the Onion", a speech held at 31C3 recently, I spontanuously decided to also run a Tor relay. After some back and forth it appears to be running fine on my OpenWRT based router. The only ORPort is 9001, which is also the only hole punched into the firewall, I hope I did this right. Today I wanted to continue at Freenode IRC, like I did for years, not even using an anonymous connection. But they wouldn't let me in: [12:02] * You are banned from this server- Your tor exit node must not allow connections to freenode (tor exit node (chat.freenode.net:8000)). Email tor-kline(a)freenode.net when corrected. (2015/1/24 09.41) I understand that my router and my PC share the same IP address to the remaining internet and IRC operators try to identify users by their IP address (which isn't possible). Reading up on the matter I found two texts: http://www.freenode.org/policy.shtml "The freenode network welcomes Tor users" http://www.freenode.org/irc_servers.shtml#tor "If you do want to be a Tor exit node and still use freenode, you will have to configure your exit policy to block all of the IRC ports we use, in addition to ports 80 and 443 as these are used for webchat." To me this sounds like "We welcome it, but please block all of its usage". They recommend to add a "reject *:*" rule, but that means the relay is no longer a relay, right? And blocking port 80 and 443 means Tor to become useless. As I can't find much on the matter by googling: is this actually a misalignment of Freenodes' statement to freedom as bad as it looks? If yes, what could I do about it? I'm a fairly experienced hobbyist hacker and admin, so I wouldn't fear writing some code. Cheers, Markus -- - - - - - - - - - - - - - - - - - - - Dipl. Ing.

New relay not recognised by weathermap
by Sharif Olorin 30 Mar '15

30 Mar '15

Hi all, I configured a new relay[0] yesterday, and recently tried to sign up for the Weathermap[1], wherein I get a "could not locate a Tor node with that fingerprint" error message. The node's definitely been up for more than an hour, and Atlas can see it[2]. Is this expected behaviour, or might it indicate an issue with my configuration? I've checked everything on the "potential problems" list - the node does exist, the fingerprint is correct, it's been up for more than an hour, hasn't been down for over a year, and running a recent (0.2.5.11) version of Tor. Thanks, Sharif [0] dendrocyte.wiredlaboratories.com.au/03B5C7B81CA56DF3CCC31FDA8032A7763B8B50B4 [1] https://weather.torproject.org/subscribe/ [2] https://atlas.torproject.org/#details/03B5C7B81CA56DF3CCC31FDA8032A7763B8B5… -- PGP: 6FB7 ED25 BFCF 3E22 72AE 6E8C 47D4 CE7F 6B9F DF57

Re: [tor-relays] Installing obfs4 on Raspberry Pi bridge
by jchase 30 Mar '15

Thanks for your answer. Your instructions were good and explicit, but you hit on two of the problems I run into. I installed tor 0.2.5.11-1 from torproject.org and got two error messages that I couldn't solve. I would have to go back and re-install 0.2.5.11-1 to tell you what they were. In any case they weren't configuration problems. I had pretty much the same problem months ago when I installed a tor 0.2.5.x on Pi. Which leads me to want to use a raspbian repo. only I am unable to get /etc/apt/sources.list to recognize http://archive.raspbian.org/raspbian/pool/main/t/tor/ (or variations thereof) as a repository. And in my main raspian repo tor doesn't go any higher than 0.2.4.26 . So simply updating tor does not work. How do I add http://archive.raspbian.org/raspbian/pool/main/t/tor/ http://archive.raspbian.org/raspbian/pool/main/o/obfs4proxy/ http://archive.raspbian.org/raspbian/pool/main/libc/libcap2/ as one or more alternative repositories or force an install?

https://globe.torproject.org/#/relay/9DCF76179FCF47224D235ECD4A6165FED22ECE… So, i am running exit node. My provider send me an email .. "This IP is infected with, or is NATting for a machine infected with s_downloaderbot-mxb" Any idea what can i do with this problem ? Now i can see my IP in my server exit policy ... After my "delist action" is clean .. http://www.senderbase.org/lookup/ip/?search_string=37.157.192.208 I need just wait ? And all outgoing packet from my server still droped ? Thanks ..
